Laundry heat recovery system  

SciTech Connect

A laundry heat recovery system includes a heat exchanger associated with each dryer in the system, the heat exchanger being positioned within the exhaust system of the dryer. A controller responsive to the water temperature of the heat exchangers and the water storage for the washer selectively circulates the water through a closed loop system whereby the water within the exchangers is preheated by the associated dryers. By venting the exhaust air through the heat exchanger, the air is dehumidified to permit recirculation of the heated air into the dryer.

Commercial laundry heat recovery system  

SciTech Connect

In a commercial laundry that is connected to a source of fresh water and generates heated waste water, a method is described for recovering heat from the heated waste comprising the steps of: (a) pumping the heated waste water through a heat exchanger; (b) introducing fresh water into the heat exchanger to receive heat from the waste water through a heat transfer effected by the heat exchanger; (c) withdrawing a first proportion of the heated fresh water at a first temperature; (d) conveying the first proportion of the heated fresh water to cold water storage tank; (e) withdrawing a second proportion of the heated fresh water at a second temperature higher than the first temperature; (f) conveying the second proportion of the heated fresh water to a hot water storage tank.

Commercial laundry heat recovery system  

SciTech Connect

Waste water of above ambient temperature in a commercial laundry is directed through a self-cleaning plate and frame heat exchanger to heat incoming fresh water. Some of the fresh water heated to a first temperature is directed to a cold water storage tank to raise the water therein above ambient temperature which results in substantially lessened downstream requirements for heat input with commensurate cost reductions. The remainder of the fresh water is heated to a higher second temperature and is directed to a hot water storage tank. A system of valves regulates the temperature of the water flowing into each of the hot and cold water storage tanks to maintain a preset temperature in each of the storage tanks.

Heat recovery in laundry yields 18-month payback  

SciTech Connect

A heat exchanger used to preheat hot water in a commercial laundry paid for itself in 19 months, despite a 10% increase in local natural gas rates. The Aurora, Illinois hospital commercial laundry chose a water-to-water shell and tube heat reclaimer system. A programmed control panel opens and closes valves at the proper temperature. Dirty water from the laundry cycle is screened to remove particles and returned to the heat exchanger to preheat incoming city water. Dirty water from the exchanger is discharged into the city sewer.

Laundry list  

SciTech Connect

The laundry list approach characterized early building conservation efforts in which checklists of varying lengths could guide building owners and systems designers toward energy consevation. These lists failed to warn that performance would be reduced and that this would have an effect on integrated systems. Operating costs also increased. The data gathered from energy audits and building studies can now be used to develop more useful lists to remind designers and analysts of the categoris for fuel or electric energy in which significant energy is used and toward which conservation efforts should be directed. The categories for large commerical and institutional buildings inlude space heat, control heat, domestic hot water, exhaust fans, lighting, refrigeration, and cooling/heating auxiliaries.

Heating remote rooms in passive solar buildings  

DOE Green Energy (OSTI)

Remote rooms can be effectively heated by convection through a connecting doorway. A simple steady-state equation is developed for design purposes. Validation of a dynamic model is achieved using data obtained over a 13-day period. Dynamic effects are investigated using a simulation analysis for three different cases of driving temperature; the effect is to reduce the temperature difference between the driving room and the remote room compared to the steady-state model. For large temperature swings in the driving room a strategy which uses the intervening door in a diode mode is effective. The importance of heat-storing mass in the remote room is investigated.

Process and apparatus for conserving energy in laundry equipment  

SciTech Connect

In a tumbler type of dryer, particularly for large capacity commercial and institutional laundries, a heating control system is provided which is responsive to the rate of increase of temperature of hot air leaving the dryer. When this temperature increase exceeds a preselected rate the dryer control system is automatically instructed to shut off or diminish the hot air supply, as well as the tumbler operation if desired. Thus energy is not wastefully consumed after the laundry is already dry; on the other hand, the dryer does not prematurely shut down while laundry is still damp, whereby the dryer must be started up again and energy again is unnecessarily wasted. Different settings are selected in accordance with the characteristics of the type of laundry being processed.

Energy and the laundry process  

SciTech Connect

Energy usage in the residential laundry process is discussed. The various parts of the washing and drying cycles and areas where energy is being wasted or where its usage can be optimized are analyzed. The application of R and D to these areas will result in energy savings. The work was centered on standard and large-size automatic washers and dryers, as compact, portable, and manual models comprise a small part of the market. However, the principles discussed apply to them also. Data from many sources were used to compile this report. Most sources show very good general agreement so far as energy consumption and usage patterns are concerned. The results suggest that improved and/or integrated controls utilizing modern electronics can indeed help conserve energy. A better understanding by the consumer of the factors involved in the laundry process can also lead to the purchase and wise use of that laundry equipment which best suits the individual needs.

Energy survey of Army Laundry Facilities, Fort Bragg, North Carolina. Executive summary. Final report  

SciTech Connect

This Final Report details Energy Conservation Opportunities (ECOs) for the Laundry and Boiler Plant at Fort Bragg, North Carolina. The ECOs noted in the table on the next page were evaluated for individual energy savings and are recommended for implementation. The energy savings and implementation costs for each measure are summarized on the following page in order of decreasing savings-to-investment (SIR) ratio. ECIP life cycle cost analyses were performed on all ECOs as a preliminary step, though all of the measures will fall into other funding categories. Because of the high internal heat gain produced in the Laundry, coupled with the fact that the laundry is not air conditioned, building envelope measures do not produce any energy savings. The most viable ECOs are related to the Boiler Plant (Boiler Replacement), recovering energy wasted in the wash water (Rinse Water Reuse) or utilizing Low Temperature Wash Water, and Changing the Hours of Laundry Operation. Additional operation and maintenance items are listed that can be addressed by the Directorate of Engineering and Housing (DEH) or the Laundry contractor, Integrity Management International, Inc., to generate quick energy savings. There are also several items included that will not produce energy savings but will improve the comfort level of the Laundry. These items should be given consideration as a method of improving productivity and/or employee morale. All ECOs evaluated by the project team are described in detail with engineering calculations for each following in Appendix 2.

Estimation of Radionuclide Content in Contaminated Laundry  

SciTech Connect

Radioactively contaminated laundry is normally sent off site for processing. Laundry is defined as radiologically contaminated anti-cs and respirators. This laundry is shipped as "limited quantity," in accordance with 49CFR173.421. This requires that 95% of the radionuclides shipped are characterized and quantified. In addition, the total quantity must be 10(-3) below the A2 limits specified in 49CFR173. In any facility evaluated, the most conservative (highest activity) waste stream was used as the source term. If a new waste stream is established for a facility, its normalized activity should be compared to the evaluated waste stream to ensure the limits are not exceeded. This article documents a method used for estimating the radionuclide content in contaminated laundry. The maximum values were compared to 49CFR173. Itwas determined that if the contaminated laundry/respirators are shipped in an Interstate Nuclear Services (INS), L-59, limited quantity shipping container and the highest contact radiation level on any side, as measured with an ion chamber, does not exceed 0.5 mR h(-1), the container complies with the requirements of 49CFR173 and could be shipped "limited quantity" from any of the facilities evaluated.

AN IONIZATION CHAMBER LAUNDRY MONITOR  

SciTech Connect

The determination of the amount of contamination remaining on a garment after it has been washed is an important part of hot laundry operations. In the past garments were monitored by measuring the contamination concentrated in the crotch with a GM tube probe. This type of spot check does not detect any isolated hot spots on other pants of the garment. To monitor the entire garment with a GM tube instrument is excessively time consuming for a large number of garments. To overcome these difficulties a sensitive, large-volume ionization chamber was constructed. It is rectangular in shape, 5 ft high by 2 1/2 ft wide by 4 in. deep. The center electrode is of a grid type and is mounted halfway between the front window and the back of the chamber. In a 0.5-mr/hr field, 180 v is sufficient to saturate toe chamber. In order to insure beta sensitivity, the front window has an equivalent thickness of approximately 7 mg/cm/sup 2/. The measuring device is a line-operated electrometer circuit equipped with an alarm that may be set at the rejection limit for the type of garment being monitored. A fullscale deflection on the most sensitive range is given by 2 to 3 mu C of liquid mixed fission products deposited on a garment. Since the chamber monitors the entire garment, the results are independent of the location of the contarnination. In practice, garments may be monitored at the rate of 7 per min, while only 3 per min may be completely checked with a GM tube probs. Field tests indicate that this instrument is stable and trouble free. Background causes a meter deflection of about 20 divisions, which is low enough to give reliable accuracy for monitoring garments. (auth)

CLOTHING DECONTAMINATION AND EVALUATION OF LAUNDRY METHODS  

SciTech Connect

The over-all objectives of this project encompassed testing the suitability of standard and special laundering methods and standard equipment for field decontamination of clothing; evaluating the contaminability and decontaminability of selected fabrics, and testing of experimental clothing monitoring instruments. Garments and fabrics contaminated by controlled methods were used during the operation for testing the equipment and evaluating fabrics and formulae. 8tandard Army laundering methods and equipment, including wooden washers, were effective for decontaminating clothing in the field. A decontaminating laundry formula employing citric acid and tartaric acid followed by either an organic or inorganic chelating agent results in a higher degree of decontamination than other formulae tested. The standard Quartermaster Corps mobile field laundry formula resulted in satisfactory decontamination with the type of soil and activity encountered and the cost of supplies is approximately one-tenth as much as the special formulae. Woolen garments and fabric swatches were decontanninated by laundering as readily as cotton or synthetic fabrics. Clothing monitoring instruments under development appear suitable for monitoring clothing under field conditions to determine the degree of contamination both before and after precessing. (auth)

The system utilizes 140 collectors manufactured by Ying. The collectors are flat plate and lexan glazed. They provide an effective aperture area of 6500 square feet. The collectors are mounted in 24 rows on the flat roof of the building. The 12,500 gallon insulated fiberglass storage tank is mounted on an above ground slab in a partially enclosed area. All solar energy system piping is copper. All exterior piping is insulated with fiberglass covered by an aluminum jacket. The solar energy system is used in conjunction with a heat recovery system. Softened cold water is first pumped through a heat exchanger which recovers heat from the laundry wastewater. The water then flows into the solar storage tank and circulates through the collectors. It is then pumped through another heat exchanger which boosts the water to the required temperature of 170/sup 0/F. Steam from a low pressure gas-fired boiler located in the building is used as the auxiliary energy source. The hot water is stored in a 4,000 gallon holding tank which contains an immersed heat exchanger that adds heat to the water from the steam condensate. The ARATEX solar system has an average hot water demand of over 30,000 gallons per day at a temperature of 180/sup 0/F. The heat recovery system reduced the hot water load at the laundry by 30 percent. Of the remaining load, 25 percent was provided by solar energy.

Ultrafiltration treatment for liquid laundry wastes from nuclear power stations  

SciTech Connect

The authors conduct a comprehensive analysis of the waste constituents--radioactive and organic--of the laundry water resulting from the on-site laundering and decontamination of clothing worn in nuclear power plants. The primary isotope contaminants consist of niobium and zirconium 95, manganese 54, cobalt 60, iron 59, and cesium 134 and 137. A variety of filter and adsorbent materials used in an ultrafiltration process are comparatively tested for their effectiveness in removing not only these isotopes but also the organic contaminants in the process of recycling the water. Those materials consist of copper hexacyanoferrate, polyacrylophosphonic acid, and several metal-polymer complexes.

What happened on the way to the laundry?  

SciTech Connect

In Santa Fe, New Mexico, there is an Interstate Nuclear Services (INS) laundry that washes protective clothing worn by workers at nuclear facilities such as Los Alamos National Laboratory (LANL)-clothing that can be contaminated with radioactive material. Some of the radioactivity goes into the sewer system, thereby going to the wastewater treatment plant (WWTP) and then coming out in the water effluent or the digested sludge. Some of the water effluent is used to water playing fields, a golf course, and the infield of the horse-racing track, and the sludge is interred into a field. This study investigates contamination from a waste water treatment plant.

Method and apparatus for improving the fuel efficiency of a laundry dryer  

SciTech Connect

A laundry dryer of the type having a pair of upstream and downstream side-by-side gas burners is modified by the removal of the upstream burner and replacing the burner with a reheat plenum. The reheat plenum is generally tear-shaped in cross section to provide an inlet portion having a relatively large airflow cross sectional area located laterally adjacent the burner so that the recirculated airflow enters the reheat plenum at a relatively low velocity conducive to settlement of lint therein at a point in the plenum away from high temperature heat exchange relation with the burner. The lower wall of the reheat plenum is angularly inclined and preferably curvilinear in contour and extends above the downstream burner in flame deflecting and heat exchange relation therewith to heat the recirculated air within the reheat plenum. The reheat plenum also has a discharge portion of relatively smaller cross sectional area which injects the reheated air at relatively high velocity into the flow of heated makeup air to effect mixing of the reheated and makeup airflow.

Improving laundry plant energy efficiency. A study done for the department of defense. Final report  

SciTech Connect

To comply with Presidential Executive Order 12759, which requires federal facilities to increase industrial/process energy efficiency 20 percent by the fiscal year 2000 (FYOO) in comparison with FY85, the Department of Defense must improve the efficiency of its laundry facilities. Army laundry managers presently reduce utility consumption by using setback timers on equipment and lights, disconnecting or disabling unused equipment, installing occupancy sensors in seldom-used areas, and replacing worn out conventional equipment with more efficient models. This study surveyed Army laundry facilities to determine and characterize their current condition and utility consumption. Those facilities were compared with commercial facilities of similar size, and alternative facility designs using advanced technologies were developed. This study concluded that it is still in the government`s interests to own and operate military laundry facilities. However, to isolate waste and inefficiency, Army laundries must supplement current practices by consistently monitoring their energy and utility consumption. It was also concluded that Army laundry facilities can significantly improve efficiency by adding advanced technologies to increase utility savings by further reducing energy and water consumption, and to decrease production costs by reducing the amount of labor required to process laundry.

Solar energy system performance evaluation: Aratex Services, Inc. , Industrial Laundry, Fresno, California, November 1977--May 1978  

SciTech Connect

An operational summary of how the solar energy system installed at ARATEX Services Inc., an industrial laundry located in Fresno, California, performed during the report period is provided. This analysis is made by evaluation of measured system performance and by comparison of measured climatic data with long term average climatic conditions. Performance of major subsystems is also presented to illustrate their operation. Included are: a brief system description, review of actual system performance during the report period, analysis of performance based on evaluation of meteorological load and operational conditions, and an overall discussion of results. Monthly values of average daily insolation and average ambient temperature measured at the ARATEX site are presented. Also presented are the long-term, average monthly values for these climatic parameters. The ARATEX system collected an average of 67 million Btu of solar energy per month. The available solar radiation was 75 percent of the long term average. The use of both a solar energy and heat recovery system at ARATEX has combined to reduce the total load of a system without heat recovery by approximately 45 percent. The solar energy system alone contributed 16 percent of the total hot water load at the site. Damage to the Lexan covers on fourteen of the total 140 collectors was reported. This damage is believed to have been caused by winds.

Laundry dryer lint: A novel matrix for nonintrusive environmental lead screening  

SciTech Connect

North American health agencies have set ambitious goals to reduce childhood and occupational lead poising. A central tool in attaining lead exposure reduction objectives is screening populations to identify persons at risk. The authors have identified laundry dryer lint as a novel matrix with potential use as a nonintrusive, first stage screening mechanism for households with elevated lead levels. This Edmonton, AB, pilot study provides the first measures of lead levels in household laundry dryer lint. Three populations were included: a control group, a group using communal dryers at an inner city service agency (Bissel Centre), and households where a family member had occupational exposure to lead. Background levels of lead in laundry dryer lint from a Canadian urban environment were established, households with elevated lead levels resulting from the transport of occupational lead by an adult family member were identified, and scanning electron microscopy was used to identify the form of the lead particles and determine their source.

Development of position sensitive proportional counters for hot particle detection in laundry and portal monitors  

SciTech Connect

This report summarizes research which demonstrates the use of position sensitive proportional counters in contamination monitoring systems. Both laundry monitoring and portal monitoring systems were developed. The laundry monitor was deployed at a nuclear power plant where it was used to monitor clothing during an outage. Position sensitive proportional counter based contamination monitoring systems were shown to have significant advantages over systems using conventional proportional counters. These advantages include the ability to directly measure the area and quantity of contamination. This capability permits identification of hot particles. These systems are also capable of self calibration via internal check sources. Systems deployed with this technology should benefit from reduced complexity, cost and maintenance. The inherent reduction of background that occurs when the counter is electronically divided into numerous detectors permits operation in high background radiation fields and improves detection limits over conventional technology.

In this study, we describe a new laundry system to wash clothes, including those contaminated with radionuclides, without using detergent. The main part of this system is electrolytic cell that consists of a cathode with a special coating of nickel, an anode of nickel, and a cation exchange membrane between the two electrodes. The electrolyte is supplied to the anode and the tap-water to the cathode. When an electricity of 5 volts and 25 amperes is applied to the electrodes, the processed water is produced from the cathode. This processed water containing no detergent was investigated experimentally with regard to its decontamination efficiency of radionuclides and detergency of soil as compared to the conventional washing using detergent. It was found that the processed water from this system has an ability to simultaneously remove radionuclides and soil from the cloth with good efficiency.

Los Alamos test-room results  

DOE Green Energy (OSTI)

Fourteen Los Alamos test rooms have been operated for several years; this paper covers operation during the winters of 1980-81 and 1981-82. Extensive data have been taken and computer analyzed to determine performance parameters such as efficiency, solar savings fraction, and comfort index. The rooms are directly comparable because each has the same net coefficient and solar collection area and thus the same load collector ratio. Configurations include direct gain, unvented Trombe walls, water walls, phase change walls, and two sunspace geometries. Strategies for reducing heat loss include selective surfaces, two brands of superglazing windows, a heat pipe system, and convection-suppression baffles. Significant differences in both backup heat and comfort are observed among the various rooms. The results are useful, not only for direct room-to-room comparisons, but also to provide data for validation of computer simulation programs.

Report on the Best Available Technology (BAT) for the treatment of the INEL Central Laundry and Respirator Facility (CFA-617)  

SciTech Connect

The Central Laundry and Respirator Facility (CLRF) designated by the building number of CFA-617 has been addressed as a potential source of contamination to the Central Facilities Area (CFA) subsurface drainage field which also receives waste water from the current CFA Sewage Treatment Plant (STP). Currently, discharges from the CLRF have been below set guidelines, DCG. A new STP has been proposed for the CFA. Since the CLRF has been designated as a potential source of contamination, a Best Available Technology (BAT) assessment was requested to determine what action should be taken in respect to the aqueous discharges from the CLRF. The BAT assessment involved source definition, technology evaluation, BAT matrix development, BAT selection, and BAT documentation. The BAT for the Central laundry and Respirator Facility selected the treatment which would impact the CLRF and the new STP the least in all aspects considered and was the system of filtration and a lined pond for natural evaporation of the water. The system will provide an isolation of this waste stream from all other CFA waste water which will be treated at the new STP. Waste minimization possibilities exist within the laundry process and are considered. These minimization actions will reduce the amount of waste water being released, but will result in raising the contaminate's concentrations (the total mass will remain the same). The second option was the use of ion exchange to remove the contaminates and recycle the water back to the wash and rinse cycles in the laundry. 3 refs., 9 figs., 11 tabs.

Study of the efficacy of aerosol versus nonaerosol laundry products. Final report  

SciTech Connect

The California Air Resources Board estimates that 6.6 tons of photochemically reactive organic compounds (PROC) are released into the environment in California every day because of the use of aerosol laundry products. The project studied the efficacy, ease of product use, and PROC content for three major brands of pre-wash stain removers in available product forms and for five starch products in their available product forms. Efficacy of pre-wash products was generally found to be limited. They were particularly useful for oil and ball point ink removal. Aerosols were found to be slightly superior. PROC content varied from 16-76% on aerosols; none was found in nonaerosols. Aerosols were found to be slightly easier to use by the laboratory investigator. For starches, on synthetic fabrics Faultless aerosol was found to be superior. For natural fabrics, results were mixed. Efficacy per unit cost was found to be high for bulk starches. PROC content for the two aerosols was 5.8% for Faultless and 8.5% for Niagra. Aerosols were easiest to use and bulk products rather difficult to use.

H-Coal pilot plant. Topical report: evaluation of a commercial laundry process for cleaning work clothing from a synthetic-fuels facility, E and H-12  

SciTech Connect

A scientific study was undertaken by Ashland Synthetic Fuels, Inc., to evaluate the cleaning efficiency of work clothing from the H-Coal Pilot Plant by a commercial laundry facility. Laundry process conditions for cleaning clothes were determined, and procedures were developed for laboratory analysis to detect coal liquefaction heavy distillate in work clothing and laundry wastewater. Laboratory testing and longwave ultraviolet light were used to monitor for skin contamination from recycled work clothing. Laboratory studies with spiked, unwashed cloth swatches showed a heavy distillate recovery efficiency of 86%. The laundry process was found to remove 98% of heavy distillate from spiked, washed cloth swatches. Low levels of heavy distillate and three polynuclear aromatic hydrocarbons were found in laundry wastewater, recycled work shirts and uncleaned T-shirts worn in process areas. Hydrocarbon material content in wastewater can be satisfactorily treated by process wastewater treatment units at synfuels facilities. There were data to suggest that process material accumulates in recycled work shirts (outer clothing) to about three times the level in new control shirts, but this accumulation was not noted in T-shirts (underclothing). Although residual process material was found in work shirts and gloves after cleaning, skin fluorescence monitoring with ultraviolet light indicates that skin contamination from contact with recycled gloves and work shirts is not occurring.

Evaluation of a precipitation-ion exchange process for treatment of laundry waste  

SciTech Connect

Bench-scale pilot plant studies were conducted to evaluate chemical coagulation and ion exchange for decontamination of 2724-W laundry wastewater. Chemical coagulation is accomplished at pH 11 to avoid complexant problems and assure good transuranic radionuclide removals. Clinoptilolite is used to remove cesium and strontium. Results of the pilot plant studies are summarized as follows: Decontamination factors of 70 (strontium) and more than 100 (cesium) were achieved by chemical coagulation and ion exchange. Decontamination factors exceeding 90 were measured for europium by coagulation with a combination of ferric chloride, magnesium chloride, and calcium chloride added to the wastewater at pH 11. Coagulation with these three agents in the wastewater at pH 11 was more effective for turbidity removal than coagulation with lime. Addition of up to 1.7 lb of clinoptilolite fines per 1000 gallons of wastewater during coagulation did not substantially increase strontium and cesium removal. Filtration without chemical coagulation reduced suspended solids by only 25%. About 70% of the suspended solids remaining in the filtered wastewater were removed in the zeolite column causing plugging which could not be easily dislodged by backwashing. Plugging of the ion exchange columns by previously clarified wastewater required short periods of limited backwashing to relieve the plug. The plugging is due to CaCO/sub 3/ and is not expected to be a severe problem in a full-scale plant with brief detention times between filtration and ion exchange. A high pressure surface wash should be included in the columns to break up crust or plugs at the surface of the zeolite. Centrifugation of iron sludges for 2 min at 2000 g reduced the sludge volume to about 1% of the total wastewater volume. Wet iron sludges from the sludge storage tank were readily dewatered by vacuum filtration. 14 tables, 9 figures.

Replacement solvent identification for the laundry and decontamination drycleaning system (LADDs). Final report, October 1991-March 1992  

SciTech Connect

A comprehensive industry search was carried out for the U.S. Army Natick Research, Development and Engineering Center (Natick) to identify potential solvent alternatives for use in present prototypes and future versions of Natick Laundry and Decontamination Drycleaning System (LADDS). The present LADDS prototype used 1,1,2-trichloro- 1,2,2-trifluoroethane, a chlorofluorocarbon compound known as CFC-113, as the drycleaning solvent. However, CFC-113 has been identified as a ozone-depleting compound and its production and use are scheduled for phaseout under U.S. and international regulations to protect the stratospheric ozone layer. Consequently, Natick needs to identify alternative solvents available for use in the LADDS as well as to understand the engineering design changes that may be necessary in order to use the types of solvents that will be available for future LADDS.

Compatibility of the ultraviolet light-ozone system for laundry waste water treatment in nuclear power plants  

SciTech Connect

As an alternative treatment system for laundry waste water in nuclear power plants, a system was chosen in which such organic compounds as surfactant would be oxidized by ultraviolet (UV) light and ozone. The system compatibility, UV light source, and dissolved ozone concentration were examined through experiments. First, ozone gas was absorbed in the waste water. After the dissolved ozone concentration equilibrated at the desired value, the waste water was irradiated by a mercury lamp. Then, the time dependence of the concentrations of the organic compounds, the dissolved ozone, and the hydrogen peroxide were measured to estimate the treatment rate of the system. The mercury lamp with a 10{sup 5}-Pa vapor pressure achieved large UV radiation and a treatment rate increase, leading to a compatible system without secondary waste generation. The effect of the dissolved ozone concentration on the treatment rate was saturated when concentration was >3.3 {times} 10{sup {minus}4} mol/10{sup {minus}3} m{sup 3} at the time UV radiation was started. Numerical results indicated the saturation was due to hydrogen peroxide generation, which prevents hydroxyl radical generation.

Geothermal heating for Caliente, Nevada  

DOE Green Energy (OSTI)

Utilization of geothermal resources in the town of Caliente, Nevada (population 600) has been the objective of two grants. The first grant was awarded to Ferg Wallis, part-owner and operator of the Agua Caliente Trailer Park, to assess the potential of hot geothermal water for heating the 53 trailers in his park. The results from test wells indicate sustainable temperatures of 140/sup 0/ to 160/sup 0/F. Three wells were drilled to supply all 53 trailers with domestic hot water heating, 11 trailers with space heating and hot water for the laundry from the geothermal resource. System payback in terms of energy cost-savings is estimated at less than two years. The second grant was awarded to Grover C. Dils Medical Center in Caliente to drill a geothermal well and pipe the hot water through a heat exchanger to preheat air for space heating. This geothermal preheater served to convert the existing forced air electric furnace to a booster system. It is estimated that the hospital will save an average of $5300 in electric bills per year, at the current rate of $.0275/KWH. This represents a payback of approximately two years. Subsequent studies on the geothermal resource base in Caliente and on the economics of district heating indicate that geothermal may represent the most effective supply of energy for Caliente. Two of these studies are included as appendices.

Research on Thermal Properties in a Phase Change Wallboard Room Based on Air Conditioning Cold Storage  

E-Print Network (OSTI)

After comparing the thermal performance parameters of an ordinary wall room to a phase change wall (PCW) room, we learn that phase change wallboard affects the fluctuation of temperature in air-conditioning room in the summer. We built a PCW room and an ordinary wall room, which are cooled by an air-conditioner. We used differential scanning calorimetry (DSC) to test the temperature field and heat flow fluctuation in these rooms. Through analyzing the data tested, we found that the mean temperature of PCW is lower than that of ordinary wall room by 1 to 2?, and PCW can lower the heat flow by 4.6W/m2. Combining phase change material with the building envelope can lower the indoor temperature, make the room thermally comfortable, and cut down the turn-on-and-off frequency of the air-conditioner and the primary investment and operating costs. It alleviates the urgent need for electricity.

Ground Loops for Heat Pumps and Refrigeration  

E-Print Network (OSTI)

Ground loops are used for water source heat pumps. Refrigeration can be put on a ground loop. Water-cooled condensing units are more efficient than air-cooled, and they can be put indoors. Indoor location makes piping for desuperheater hot water easy. Since refrigeration equipment runs more than heat pumps, energy savings can be large for ground-coupled refrigeration. The paper presents a design procedure for ground loops for heat pumps, hot water, ice machines, and water-cooled refrigeration. It gives an overview of the commercial ground-coupled systems in Louisiana that have both refrigeration and heat pumps. Systems vary from small offices to a three-story office building with 187 tons. A chain of hamburger outlets uses total ground-coupling in all of its stores. A grocery store has ground-coupling for heat pumps and refrigeration. Desuperheaters provide 80 percent of the hot water for a coin laundry in the same building. A comparison of energy costs in a bank with a ground-coupled heat pump system to a similar bank with air-conditioning and gas for heat revealed a 31 percent reduction in utility costs for the ground-coupled building. Two buildings of the Mississippi Power and Light Co. have ground-coupled heat pumps in one, and high efficiency air source heat pumps in the other. Energy savings in nine months was 60,000 kWh (25 percent), and electric peak demand was reduced 42 kW (35 percent).

Control and Room Temperature Optimization of Energy Efficient Buildings  

SciTech Connect

The building sector consumes a large part of the energy used in the United States and is responsible for nearly 40% of greenhouse gas emissions. It is therefore economically and environmentally important to reduce the building energy consumption to realize massive energy savings. In this paper, a method to control room temperature in buildings is proposed. The approach is based on a distributed parameter model represented by a three dimensional (3D) heat equation in a room with heater/cooler located at ceiling. The latter is resolved using finite element methods, and results in a model for room temperature with thousands of states. The latter is not amenable to control design. A reduced order model of only few states is then derived using Proper Orthogonal Decomposition (POD). A Linear Quadratic Regulator (LQR) is computed based on the reduced model, and applied to the full order model to control room temperature.

Energy Consumption Estimation for Room Air-conditioners Using Room Temperature Simulation with One-Minute Intervals  

E-Print Network (OSTI)

For the purpose of developing optimized control algorithm for room air-conditioners to ensure their energy efficiency, a short time interval (i.e., one minute) simulation of building thermal performance is necessary because the sampling time interval for room air-conditioner control is one minute in general. This paper studies the short-time interval room air temperature simulation method using the response factor method. Using the simulated room air temperature, an air-conditioner's running time can be known so that its energy consumption can be estimated accurately. In order to verify the simulation accuracy, an actual room equipped with a gas-engine heat pump (GHP) air-conditioning system is studied by both simulation and measurement. The cooling amount produced by the GHP is calculated using measured refrigerant pressure and temperature at condenser and evaporator respectively. The Root Mean Square Error (RMSE) between measured cooling amount and simulated cooling load is 18.9 percent of the average measured value. The profile of simulated room air temperature in both air-conditioned daytime and nighttime without air-conditioning can match the measured room air temperature. With respect to the estimated energy consumption, the profile of simulated energy consumption can match the measured data. The simulation accuracy of room air temperature and energy consumption during the air-conditioner start-up period is not good and needs to be improved in future research. But in general, the verification shows that this energy consumption simulation method is acceptable for evaluating the energy performance of a room air-conditioner, and can also be a useful tool for commissioning room air-conditioners.

Environmental Management Waste Management Facility Waste Lot Profile 155.5 for K-1015-A Laundry Pit, East Tennessee Technology Park Oak Ridge, Tennessee  

DOE Green Energy (OSTI)

In 1989, the Oak Ridge Reservation (ORR), which includes the East Tennessee Technology Park (ETTP), was placed on the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) National Priorities List. The Federal Facility Agreement (FFA) (DOE 1992), effective January 1, 1992, now governs environmental restoration activities conducted under CERCLA at the ORR. Following signing of the FFA, U.S. Department of Energy (DOE), U.S. Environmental Protection Agency (EPA), and the state of Tennessee signed the Oak Ridge Accelerated Cleanup Plan Agreement on June 18, 2003. The purpose of this agreement is to define a streamlined decision-making process to facilitate the accelerated implementation of cleanup, to resolve ORR milestone issues, and to establish future actions necessary to complete the accelerated cleanup plan by the end of fiscal year 2008. While the FFA continues to serve as the overall regulatory framework for remediation, the Accelerated Cleanup Plan Agreement supplements existing requirements to streamline the decision-making process. The disposal of the K-1015 Laundry Pit waste will be executed in accordance with the 'Record of Decision for Soil, Buried Waste, and Subsurface Structure Actions in Zone, 2, East Tennessee Technology Park, Oak Ridge, Tennessee' (DOB/ORAH-2161&D2) and the 'Waste Handling Plan for the Consolidated Soil and Waste Sites with Zone 2, East Tennessee Technology Park, Oak Ridge, Tennessee' (DOE/OR/01-2328&D1). This waste lot consists of a total of approximately 50 cubic yards of waste that will be disposed at the Environmental Management Waste Management Facility (EMWMF) as non-containerized waste. This material will be sent to the EMWMF in dump trucks. This profile is for the K-1015-A Laundry Pit and includes debris (e.g., concrete, metal rebar, pipe), incidental soil, plastic and wood, and secondary waste (such as plastic sheeting, hay bales and other erosion control materials, wooden pallets, contaminated equipment, decontamination materials, etc.).

Solar ponds for industrial process heat  

DOE Green Energy (OSTI)

Solar ponds offer perhaps the simplest technique for conversion of solar energy to thermal energy, which can be used for industrial process heat. It is unique in its capability in acting both as collector and storage. Further, the cost of solar pond per unit area is less than any active collectors available today. Combination of these economic and technical factors make solar ponds attractive as a fuel saver in IPH applications. Detailed calculations are given for solar ponds in two specific applications: providing hot water for aluminum can washing in a manufacturing plant and hot water for washing in a large commercial laundry. With the help of computer codes developed at SERI for other solar IPH systems, it is shown that solar ponds are far more cost effective than any other solar IPH technology for these applications.

Room temperature terahertz polariton emitter  

SciTech Connect

Terahertz (THz) range electroluminescence from intersubband polariton states is observed in the ultra strong coupling regime, where the interaction energy between the collective excitation of a dense electron gas and a photonic mode is a significant portion of the uncoupled excitation energy. The polariton's increased emission efficiency along with a parabolic electron confinement potential allows operation up to room temperature in a nonresonant pumping scheme. This observation of room temperature electroluminescence of an intersubband device in the THz range is a promising proof of concept for more powerful THz sources.

Applications Tests of Commercial Heat Pump Water Heaters  

E-Print Network (OSTI)

Field application tests have been conducted on three 4 to 6-ton commercial heat pump water heater systems in a restaurant, a coin-operated laundry, and an office building cafeteria in Atlanta. The units provide space cooling while rejecting heat to a water heating load. The tests, conducted for Georgia Power Company, examined both quantitative and qualitative aspects of the heat pumps and the overall water heating systems. The results provide valuable insight into the actual operating characteristics of heat pump water heaters and useful guidelines for system design and operation. The capacity and efficiency of the units agreed with manufacturers' specifications. COP values ranged from 2 .6 to 3.0 for water heating only, and from 4.1 to 5.0 when space cooling benefit was included. It was concluded that heat pump water heaters can provide economical water heating and space conditioning. However, application sites must be selected within certain constraints and a minimum level of operating control and maintenance must be observed.

Forecasting Uncertain Hotel Room Demand  

E-Print Network (OSTI)

Economic systems are characterized by increasing uncertainty in their dynamics. This increasing uncertainty is likely to incur bad decisions that can be costly in financial terms. This makes forecasting of uncertain economic variables an instrumental activity in any organization. This paper takes the hotel industry as a practical application of forecasting using the Holt-Winters method. The problem here is to forecast the uncertain demand for rooms at a hotel for each arrival day. Forecasting is part of hotel revenue management system whose objective is to maximize the revenue by making decisions regarding when to make rooms available for customers and at what price. The forecast approach discussed in this paper is based on quantitative models and does not incorporate management expertise. Even though, forecast results are found to be satisfactory for certain days, this is not the case for other arrival days. It is believed that human judgment is important when dealing with ...

Water heaters are defined by NAECA as products that utilize oil, gas, or electricity to heat potable water for use outside the heater upon demand. These are major appliances, which use a large portion (18% on average) of total energy consumed per household (1). They differ from most other appliances in that they are usually installed in obscure locations as part of the plumbing and are ignored until they fail. Residential water heaters are capable of heating water up to 180{degrees}F, although the setpoints are usually set lower.

The Influence of Operating Modes, Room Temperature Set Point and Curtain Styles on Energy Consumption of Room Air Conditioner  

E-Print Network (OSTI)

A field investigation was carried out in an office building of Changsha city in winter and summer, the influence of different running modes, curtain styles and room temperature set point on energy consumption of room air conditioner (RAC) was studied. The results show that: In summer automatic speed mode consumes the least refrigerating energy in different running modes, compared with low speed and high speed modes, it can conserve energy for 27.3% and 15.8%, respectively. In the same running mode, setting outer curtain can conserve energy for 40.9% and 20.4% compared with no curtain and inner curtain states, respectively. In winter high speed mode is the most efficient for saving energy which can decrease 40.3% and 30.9% compared with low speed and automatic speed modes. In the same running mode, setting inner curtain state makes the least heating energy consumption in cloudy day, about 10.8% and 2.7% less than no curtain and outer curtain states. However, it is not obvious when the day is fine. The heating energy consumption decreases as room temperature set point falls, compared with the energy consumption at 20.5 C and 19.5 C, it is decreases for 34.1% and17.0 % at 18.5 C, respectively. All the results will be the reference of environment design and control for air conditioning room.

Novel room temperature ferromagnetic semiconductors  

SciTech Connect

Today's information world, bits of data are processed by semiconductor chips, and stored in the magnetic disk drives. But tomorrow's information technology may see magnetism (spin) and semiconductivity (charge) combined in one 'spintronic' device that exploits both charge and 'spin' to carry data (the best of two worlds). Spintronic devices such as spin valve transistors, spin light emitting diodes, non-volatile memory, logic devices, optical isolators and ultra-fast optical switches are some of the areas of interest for introducing the ferromagnetic properties at room temperature in a semiconductor to make it multifunctional. The potential advantages of such spintronic devices will be higher speed, greater efficiency, and better stability at a reduced power consumption. This Thesis contains two main topics: In-depth understanding of magnetism in Mn doped ZnO, and our search and identification of at least six new above room temperature ferromagnetic semiconductors. Both complex doped ZnO based new materials, as well as a number of nonoxides like phosphides, and sulfides suitably doped with Mn or Cu are shown to give rise to ferromagnetism above room temperature. Some of the highlights of this work are discovery of room temperature ferromagnetism in: (1) ZnO:Mn (paper in Nature Materials, Oct issue, 2003); (2) ZnO doped with Cu (containing no magnetic elements in it); (3) GaP doped with Cu (again containing no magnetic elements in it); (4) Enhancement of Magnetization by Cu co-doping in ZnO:Mn; (5) CdS doped with Mn, and a few others not reported in this thesis. We discuss in detail the first observation of ferromagnetism above room temperature in the form of powder, bulk pellets, in 2-3 mu-m thick transparent pulsed laser deposited films of the Mn (<4 at. percent) doped ZnO. High-resolution transmission electron microscopy (HRTEM) and electron energy loss spectroscopy (EELS) spectra recorded from 2 to 200nm areas showed homogeneous distribution of Mn substituting for Zn a 2+ state in the ZnO lattice. Ferromagnetic Resonance (FMR) technique is used to confirm the existence of ferromagnetic ordering at temperatures as high as 425K. The ab initio calculations were found to be consistent with the observation of ferromagnetism arising from fully polarized Mn 2+ state. The key to observed room temperature ferromagnetism in this system is the low temperature processing, which prevents formation of clusters, secondary phases and the host ZnO from becoming n-type. The electronic structure of the same Mn doped ZnO thin films studied using XAS, XES and RIXS, revealed a strong hybridization between Mn 3d and O 2p states, which is an important characteristic of a Dilute magnetic Semiconductor (DMS). It is shown that the various processing conditions like sintering temperature, dopant concentration and the properties of precursors used for making of DMS have a great influence on the final properties. Use of various experimental techniques to verify the physical properties, and to understand the mechanism involved to give rise to ferromagnetism is presented. Methods to improve the magnetic moment in Mn doped ZnO are also described. New promising DMS materials (such as Cu doped ZnO are explored). The demonstrated new capability to fabricate powder, pellets, and thin films of room temperature ferromagnetic semiconductors thus makes possible the realization of a wide range of complex elements for a variety of new multifunctional phenomena related to Spintronic devices as well as magneto-optic components.

Fundamental heat transfer experiments of heat pipes for turbine cooling  

SciTech Connect

Fundamental heat transfer experiments were carried out for three kinds of heat pipes that may be applied to turbine cooling in future aero-engines. In the turbine cooling system with a heat pipe, heat transfer rate and start-up time of the heat pipe are the most important performance criteria to evaluate and compare with conventional cooling methods. Three heat pipes are considered, called heat pipe A, B, and C, respectively. All heat pipes have a stainless steel shell and nickel sintered powder metal wick. Sodium (Na) was the working fluid for heat pipes A and B; heat pipe C used eutectic sodium-potassium (NaK). Heat pipes B and C included noncondensible gas for rapid start-up. There were fins on the cooling section of heat pipes. In the experiments, an infrared image furnace supplied heat to the heat pipe simulating turbine blade surface conditions. In the results, heat pipe B demonstrated the highest heat flux of 17 to 20 W/cm{sup 2}. The start-up time was about 6 minutes for heat pipe B and about 6 minutes for heat pipe A. Thus, adding noncondensible gas effectively reduced start-up time. Although NaK is a liquid phase at room temperature, the start-up time of heat pipe C (about 7 to 8 minutes) was not shorter than the heat pipe B. The effect of a gravitational force on heat pipe performance was also estimated by inclining the heat pipe at an angle of 90 deg. There was no significant gravitational dependence on heat transport for heat pipes including noncondensible gas.

Waste water heat recovery appliance. Final report  

SciTech Connect

An efficient convective waste heat recovery heat exchanger was designed and tested. The prototype appliance was designed for use in laundromats and other small commercial operations which use large amounts of hot water. Information on general characteristics of the coin-op laundry business, energy use in laundromats, energy saving resources already in use, and the potential market for energy saving devices in laundromats was collected through a literature search and interviews with local laundromat operators in Fort Collins, Colorado. A brief survey of time-use patterns in two local laundromats was conducted. The results were used, with additional information from interviews with owners, as the basis for the statistical model developed. Mathematical models for the advanced and conventional types were developed and the resulting computer program listed. Computer simulations were made using a variety of parameters; for example, different load profiles, hold-up volumes, wall resistances, and wall areas. The computer simulation results are discussed with regard to the overall conclusions. Various materials were explored for use in fabricating the appliance. Resistance to corrosion, workability, and overall suitability for laundromat installations were considered for each material.

Heating Water with Solar Energy Costs Less at the Phoenix Federal Correctional Institution  

SciTech Connect

A large solar thermal system installed at the Phoenix Federal Correctional Institution (FCI) in 1998 heats water for the prison and costs less than buying electricity to heat that water. This renewable energy system provides 70% of the facility's annual hot water needs. The Federal Bureau of Prisons did not incur the up-front cost of this system because it was financed through an Energy Savings Performance Contract (ESPC). The ESPC payments are 10% less than the energy savings so that the prison saves an average of$6,700 per year, providing an immediate payback. The solar hot water system produces up to 50,000 gallons of hot water daily, enough to meet the needs of 1,250 inmates and staff who use the kitchen, shower, and laundry facilities.

Designing for man: advances in control room operation  

SciTech Connect

Considers the human factor in nuclear power plants in relation to improving control room and maintenance operations. Control room operators face thousands of dials, meters, and indicator lights dispersed over large control boards. Components may not be arranged in clearly identifiable panels of related elements; sometimes related controls may not be near each other. Extensive alarm systems may sometimes confuse rather than alert the operators; communications with other parts of the plant may be difficult. Maintenance personnel may have to squeeze past pipes and similar obstructions to make repairs while carrying equipment and tools, sometimes while wearing protective gear. EPRI has developed a cool suit consisting of 16 pounds of water-filled compartments built into a two-piece repair suit that can be frozen to keep body temperatures at acceptable levels for up to 2 hrs. in high-heat areas of the plant. An ergonomics guide, which examines alternative solutions to heat stress (such as rest cycles and worker screening) is also being developed. Because few new nuclear plants are currently being built, many of the improvements will be retrofits in existing plants. EPRI's human factors work emphasizes thorough validation of new techniques through simulators and mockups.

Hodgson, Toshifumi Hotchi, Katherine Y. Ming, Richard G. Sextro, Emily E. Wood, and Nancy J. Brown Journal Atmospheric Environment Volume 41 Start Page Chapter Pagination 3251-3265 Keywords adsorption, hazardous air pollutants, nerve agents, sink effect, volatile organic compounds Abstract Experiments were conducted to characterize organic gas sorption in residential rooms studied ''as-is'' with furnishings and material surfaces unaltered and in a furnished chamber designed to simulate a residential room. Results are presented for 10 rooms (five bedrooms, two bathrooms, a home office, and two multi-function spaces) and the chamber. Exposed materials were characterized and areas quantified. A mixture of volatile organic compounds (VOCs) was rapidly volatilized within each room as it was closed and sealed for a 5-h Adsorb phase; this was followed by 30-min Flush and 2-h closed-room Desorb phases. Included were alkane, aromatic, and oxygenated VOCs representing a range of ambient and indoor air pollutants. Three organophosphorus compounds served as surrogates for Sarin-like nerve agents. Measured gas-phase concentrations were fit to three variations of a mathematical model that considers sorption occurring at a surface sink and potentially a second, embedded sink. The 3-parameter sink-diffusion model provided acceptable fits for most compounds and the 4-parameter two-sink model provided acceptable fits for the others. Initial adsorption rates and sorptive partitioning increased with decreasing vapor pressure for the alkanes, aromatics and oxygenated VOCs. Best-fit sorption parameters obtained from experimental data from the chamber produced best-fit sorption parameters similar to those obtained from the residential rooms

Applications of Commercial Heat Pump Water Heaters in Hot, Humid Climates  

E-Print Network (OSTI)

Heat pump water heaters can provide high-efficiency water heating and supplemental space cooling and dehumidification in commercial buildings throughout the United States. They are particularly attractive in hot, humid areas where cooling loads are high and the cooling season is long. Because commercial kitchens and laundry facilities have simultaneous water heating and cooling needs, they are excellent applications for heat pump water heaters. Typical heat pump water heaters (HPWHs) operate at an annual coefficient of performance (COP) of approximately 3.0 for water heating alone. Space conditioning benefits of about 0.67 Btu are delivered at no additional cost for each Btu of water heating output. In situations in which this cooling output is valued, the dual thermal outputs for heating and cooling make heat pump water heaters particularly attractive. The comfort value of added cooling in overheated facilities and the resulting increase in employee and customer satisfaction are frequently cited as additional benefits. This paper describes currently available heat pump water heating equipment and offers guidelines for successful applications in commercial facilities. The results of field test programs involving more than 100 units in Alabama, Georgia, Mississippi, Tennessee, South Carolina, and other areas are incorporated. Initial conclusions are drawn from a reliability database, and interviews with utility applications specialists and manufacturers are discussed. Design tools are reviewed, including a new comprehensive computer simulation model. Emphasis is placed on identifying sound candidates for installations and on application and design considerations. A brief survey is provided of environmental implications of heat pump water heaters and new developments in heat pump water heater equipment.

Software Support during a Control Room Upgrade  

SciTech Connect

In 2004, after 14 years of accelerator operations and commissioning, Jefferson Lab renovated its main control room. Changes in technology and lessons learned during those 14 years drove the control room redesign in a new direction, one that optimizes workflow and makes critical information and controls available to everyone in the control room. Fundamental changes in a variety of software applications were required to facilitate the new operating paradigm. A critical component of the new control room design is a large-format video wall that is used to make a variety of operating information available to everyone in the room. Analog devices such as oscilloscopes and function generators are now displayed on the video wall through two crosspoint switchers: one for analog signals and another for video signals. A new software GUI replaces manual configuration of the oscilloscopes and function generators and helps automate setup. Monitoring screens, customized for the video wall, now make important operating information visible to everyone, not just a single operator. New alarm handler software gives any operator, on any workstation, access to all alarm handler functionality, and multiple users can now contribute to a single electronic logbook entry. To further support the shift to distributed access and control, many applications have been redesigned to run on servers instead of on individual workstations.

Optimal power consumption in a central heating system with geothermal heat pump  

E-Print Network (OSTI)

Abstract: A ground source heat pump connected to a domestic hydronic heating network is studied to be driven with the minimum electric power. The hypothesis is to decrease the forward temperature to the extent that one of the hydronic heaters work at full capacity. A less forward temperature would result in a dramatic temperature drop in the room with saturated actuator. The optimization hypothesis is inspired by the fact that, the consumed electric power by the heat pump has a strong positive correlation with the generated forward temperature. A model predictive control scheme is proposed in the current study to achieve the optimal forward temperature. At the lower hierarchy level, local PI controllers seek the corresponding room temperature setpoint. Simulation results for a multi-room house case study show considerable energy savings compared to the heat pumps traditional control scheme.

Method of remotely constructing a room  

DOE Patents (OSTI)

The testing of nuclear devices of high explosive yield has required that cavities of relatively large size be provided at considerable distances below the surface of the earth for the pre-detonation emplacement of the device. The construction of an essentially watertight chamber or room in the cavity is generally required for the actual emplacement of the device. A method is described of constructing such a room deep within the earth by personnel at the surface. A dual wall bladder of a watertight, pliable fabric material is lowered down a shaft into a selected position. The bladder is filled with a concrete grout while a heavy fluid having essentially the same density as the grout is maintained on both sides of the bladder, to facilitate complete deployment of the bladder by the grout to form a room of desired configuration.

A New Control Room for SLAC Accelerators  

SciTech Connect

We are planning to construct a new control room at SLAC to unify and improve the operation of the LCLS, SPEAR3, and FACET accelerator facilities, and to provide the space and flexibility needed to support the LCLS-II and proposed new test beam facilities. The existing control rooms for the linac and SPEAR3 have been upgraded in various ways over the last decade, but their basic features have remained unchanged. We propose to build a larger modern Accelerator Control Room (ACR) in the new Research Support Building (RSB) which is currently under construction at SLAC. Shifting the center of control for the accelerator facilities entails both technical and administrative challenges. In this paper, we describe the history, concept, and status of this project.

Solar heating apparatus  

SciTech Connect

The disclosure concerns a collector for solar heating apparatus which is adapted for vertical mounting and utilizes air as the heat exchange medium. The collector comprises a glazed insulated box containing a group of energy transfer units, each of which is formed by a pair of similar open top metal foil pans having flat bottom walls which are in abutment and outwardly flaring conical side walls. The pans carry a black energy-absorbing coating and preferably their abutting walls contain registering air flow openings. The energy transfer units are stacked in interfitting relationship in rows and columns, with the axes of adjacent interfitted units in each row and in each column extending in mutually perpendicular directions. The collector may be combined with a fan unit adapted to fit a standard window, thereby providing a portable, economical, auxiliary heater for a room of a building.

Experimental Research of Air Source Heat Pump Frosting and Defrosting in a Double Stage-Coupling Heat Pump  

E-Print Network (OSTI)

In a double stage-coupling heat pump, comprising an air source and water loop heat pump, the 13~20 ? low temperature water is supplied to the water loop heat pump unit. The water loop heat pump can extract heat from the water and heat the indoor air. The most common method of air source heat pump frost removal is reverse-cycle defrost. During the defrosting operation, the heat pump runs in the cooling mode. The defrost process is accomplished by reversing the normal heating mode. In this paper, the effect of the heat storage tank to the air source heat pump defrosting is test. Owing to the existence of the heat storage tank, thermal inertia of the loop is relatively high. The frosting and defrosting course of the air source heat pump have little effect on the room temperature.

Advanced nuclear plant control room complex  

DOE Patents (OSTI)

An advanced control room complex for a nuclear power plant, including a discrete indicator and alarm system (72) which is nuclear qualified for rapid response to changes in plant parameters and a component control system (64) which together provide a discrete monitoring and control capability at a panel (14-22, 26, 28) in the control room (10). A separate data processing system (70), which need not be nuclear qualified, provides integrated and overview information to the control room and to each panel, through CRTs (84) and a large, overhead integrated process status overview board (24). The discrete indicator and alarm system (72) and the data processing system (70) receive inputs from common plant sensors and validate the sensor outputs to arrive at a representative value of the parameter for use by the operator during both normal and accident conditions, thereby avoiding the need for him to assimilate data from each sensor individually. The integrated process status board (24) is at the apex of an information hierarchy that extends through four levels and provides access at each panel to the full display hierarchy. The control room panels are preferably of a modular construction, permitting the definition of inputs and outputs, the man machine interface, and the plant specific algorithms, to proceed in parallel with the fabrication of the panels, the installation of the equipment and the generic testing thereof.

Study on Energy Saving of the Interlayer Ventilation Walla Used in Clean Operation Rooms  

E-Print Network (OSTI)

Recovery energy of the exhaust in air conditioning is very important to clean operating rooms. In disinfected operating rooms, we often use completely fresh air conditioning system in order to maintain cleanliness. All the return air of the air conditioning must be discharged. For recovering the exhaust energy, whole heat exchangers are used, and they may bring cross-infection in clean operating rooms. Cross-infection would negatively affect cleanness. This paper puts forward an air layer inside of a building's external wall that acts as a passageway for air conditioning exhaust, and also providing a place for the thermal exchange of the air conditioning exhaust. This kind of envelope is named an interlayer ventilation wall. There are two advantages. First, it will recover and reutilize the energy that the air conditioning exhaust takes, avoid cross-infection between the fresh air and the exhaust. Second, it will lower the energy loss of the heat exchange through the envelope. The energy saving effect will be very significant in clean operating rooms.

Experimental study of natural convection heat transfer through an aperture in passive solar heated buildings  

DOE Green Energy (OSTI)

The objective of this study is to obtain correlations between natural convection heat transfer through an aperture and temperature difference between the two rooms. A one-fifth similitude model of a two-room building is used. The model is filled with Freon gas to satisfy similarity of the experiment to full-scale conditions in air. The experimental apparatus and experimental techniques are explained. Experimental results are presented in terms of Grashof, Nusselt, and Prandtl numbers. The effects of the height, the width, and the vertical position of the apertures are investigated, as is the effect of the room volume.

Oxygen Reordering Near Room temperature in YBa2Cu3O6+x: A Thermodynamic Model  

SciTech Connect

We propose a thermodynamic model to explain an unusual phase transformation occurring near room temperature in YBa{sub 2}Cu{sub 3}O{sub 6+x} that greatly affects properties of the superconductor. Based on our model, the material's thermodynamic response functions, specific heat, thermal-expansion coefficient, and elastic compliances are deduced at the critical temperature of the phase transformation. We discuss the change of critical temperature with stress, and analyze the anomaly of specific heat in critical temperature of the phase transformation.

Laser sheet light flow visualization for evaluating room air flowsfrom Registers  

SciTech Connect

Forced air heating and cooling systems and whole house ventilation systems deliver air to individual rooms in a house via supply registers located on walls ceilings or floors; and occasionally less straightforward locations like toe-kicks below cabinets. Ideally, the air velocity out of the registers combined with the turbulence of the flow, vectoring of air by register vanes and geometry of register placement combine to mix the supply air within the room. A particular issue that has been raised recently is the performance of multiple capacity and air flow HVAC systems. These systems vary the air flow rate through the distribution system depending on the system load, or if operating in a ventilation rather than a space conditioning mode. These systems have been developed to maximize equipment efficiency, however, the high efficiency ratings do not include any room mixing effects. At lower air flow rates, there is the possibility that room air will be poorly mixed, leading to thermal stratification and reduced comfort for occupants. This can lead to increased energy use as the occupants adjust the thermostat settings to compensate and parts of the conditioned space have higher envelope temperature differences than for the well mixed case. In addition, lack of comfort can be a barrier to market acceptance of these higher efficiency systems To investigate the effect on room mixing of reduced air flow rates requires the measurement of mixing of supply air with room air throughout the space to be conditioned. This is a particularly difficult exercise if we want to determine the transient performance of the space conditioning system. Full scale experiments can be done in special test chambers, but the spatial resolution required to fully examine the mixing problem is usually limited by the sheer number of thermal sensors required. Current full-scale laboratory testing is therefore severely limited in its resolution. As an alternative, we used a water-filled scale model of a room in which whole-field supply air mixing maps of two vertical planes were measured using a Planar Laser-Induced Fluorescence (PLIF) measurement technique. Water marked with fluorescent dye was used to simulate the supply airflow; and the resulting concentrations within the water filled model show how the supply air mixes with the room air and are an analog for temperature (for thermal loads) or fresh air (for ventilation). In addition to performing experiments over a range of flow rates, we also changed register locations and examined the effects for both heating and cooling operation by changing the water density (simulating air density changes due to temperature changes) using dissolved salt.

A performance data network for solar process heat systems  

DOE Green Energy (OSTI)

A solar process heat (SPH) data network has been developed to access remote-site performance data from operational solar heat systems. Each SPH system in the data network is outfitted with monitoring equipment and a datalogger. The datalogger is accessed via modem from the data network computer at the National Renewable Energy Laboratory (NREL). The dataloggers collect both ten-minute and hourly data and download it to the data network every 24-hours for archiving, processing, and plotting. The system data collected includes energy delivered (fluid temperatures and flow rates) and site meteorological conditions, such as solar insolation and ambient temperature. The SPH performance data network was created for collecting performance data from SPH systems that are serving in industrial applications or from systems using technologies that show promise for industrial applications. The network will be used to identify areas of SPH technology needing further development, to correlate computer models with actual performance, and to improve the credibility of SPH technology. The SPH data network also provides a centralized bank of user-friendly performance data that will give prospective SPH users an indication of how actual systems perform. There are currently three systems being monitored and archived under the SPH data network: two are parabolic trough systems and the third is a flat-plate system. The two trough systems both heat water for prisons; the hot water is used for personal hygiene, kitchen operations, and laundry. The flat plate system heats water for meat processing at a slaughter house. We plan to connect another parabolic trough system to the network during the first months of 1996. We continue to look for good examples of systems using other types of collector technologies and systems serving new applications (such as absorption chilling) to include in the SPH performance data network.

Solar process heat technology in action: The process hot water system at the California Correctional Institution at Tehachapi  

DOE Green Energy (OSTI)

Solar process heat technology relates to solar thermal energy systems for industry, commerce, and government. Applications include water preheating and heating, steam generation, process hot air, ventilation air heating, and refrigeration. Solar process heat systems are available for commercial use. At the present time, however, they are economically viable only in niche markets. This paper describes a functioning system in one such market. The California Department of Corrections (CDOC), which operates correctional facilities for the state of California, uses a solar system for providing hot water and space heating at the California Correctional Institute at Tehachapi (CCI/Tehachapi). CCI/Tehachapi is a 5100-inmate facility. The CDOC does not own the solar system. Rather, it buys energy from private investors who own the solar system located on CCI/Tehachapi property; this arrangement is part of a long-term energy purchase agreement. United Solar Technologies (UST) of Olympia Washington is the system operator. The solar system, which began operating in the fall of 1990, utilizes 2677 m{sup 2} (28,800 ft{sup 2}) of parabolic through solar concentrators. Thermal energy collected by the system is used to generate hot water for showers, kitchen operations, and laundry functions. Thermal energy collected by the system is also used for space heating. At peak operating conditions, the system is designed to meet approximately 80 percent of the summer thermal load. 4 figs., 4 tabs.

Heat reclaimer  

Science Conference Proceedings (OSTI)

A device for reclaiming heat from stove pipes and the like. A semi-circular shaped hollow enclosed housing with a highly thermal-conductive concave surface is mounted contactingly to surround approximately one-half of the circumference of the stove pipe. The concave surface is formed to contact the pipe at a maximum number of points along that surface. The hollow interior of the housing contains thin multi-surfaced projections which are integral with the concave surface and conductively transfer heat from the stove pipe and concave surface to heat the air in the housing. A fan blower is attached via an air conduit to an entrance opening in the housing. When turned on, the blower pushes the heated interior air out a plurality of air exit openings in the ends of the housing and brings in lower temperature outside air for heating.

Tritium Room Air Monitor Operating Experience Review  

SciTech Connect

Monitoring the breathing air in tritium facility rooms for airborne tritium is a radiological safety requirement and a best practice for personnel safety. Besides audible alarms for room evacuation, these monitors often send signals for process shutdown, ventilation isolation, and cleanup system actuation to mitigate releases and prevent tritium spread to the environment. Therefore, these monitors are important not only to personnel safety but also to public safety and environmental protection. This paper presents an operating experience review of tritium monitor performance on demand during small (1 mCi to 1 Ci) operational releases, and intentional airborne inroom tritium release tests. The tritium tests provide monitor operation data to allow calculation of a statistical estimate for the reliability of monitors annunciating in actual tritium gas airborne release situations. The data show a failure to operate rate of 3.5E-06/monitor-hr with an upper bound of 4.7E-06, a failure to alarm on demand rate of 1.4E-02/demand with an upper bound of 4.4E-02, and a spurious alarm rate of 0.1 to 0.2/monitor-yr.

The world's largest solar power plant is being built at Amilly, France and will be installed next year in Dire, Mali. Its capacity will be 80,000 watts. Each day it will pump 300,000 cubic feet of water up 23 feet from the Niger River to irrigate 37 acres of land. From a well 60 feet deep, it will pump another 21,200 cubic feet daily to supply drinking water for 10,000 people in Dire. It will refrigerate a cold room for an agricultural cooperative and, finally, after sundown, will generate 5 kW of electrical power to light both the cooperative and a 40-room tourist hotel.

SciTech Connect

In response to a request from management at the Northland Terrace Nursing and Rehabilitation Center (SIC-8051), Columbus, Ohio, a study was undertaken of headaches in workers in the laundry facility and upper respiratory infections associated with delivering Attends diapers. The study included employee interviews, environmental monitoring, and an assessment of the adequacy of the design and performance of the heating, ventilating, and air conditioning system. Northland Terrace was a nursing and rehabilitation center. Employees who work in the laundry facility reported that they experience headache while present in this area which was renovated in 1989. Carbon-dioxide (124389) concentrations exceeded 1000 parts per million. Biologically significant carbon-monoxide (630080) concentrations were not observed. Temperatures in the laundry rooms ranged from 86 to 92 degrees-F. Relative humidities ranged from 48 to 56%. A possible reaction to the dust or the fragrance associated with Attends diapers was not followed to completion as the nursing facility stopped using this product during the study. The authors conclude that there was an inadequate supply of outside air in the laundry and basement areas. The authors recommend measures to improve the ventilation system and reduce the potential for heat stress in the laundry.

THE CONSTRUCTION AND OPERATION OF EXPERIMENTAL ROOMS FOR THE STUDY OF AIR-BORNE INFECTION*  

E-Print Network (OSTI)

In order to carry out adequately controlled studies on the effects of temperature and humidity on the behavior of bacteria and viruses suspended in the air under various experimental conditions, it became necessary to have available enclosed spaces in which any desired atmospheric state could be produced and maintained. The use of conventional methods of air conditioning is unsuitable for this purpose because all of these depend upon exchange of the air inside the experimental space with conditioned air. Hence, two identical air-tight, glass-walled rooms 8 feet X 10 feet and 8 feet high were built each within a separate air-conditioned shell which can be kept constantly at any temperature and relative humidity likely to be encountered in spaces occupied by human beings. Rapid circulation of the conditioned air over all surfaces of the inner room provides a sufficiently high rate of heat transfer to insure constant temperature conditions within that space. The relative humidity of the inner room can be maintained at the same level as the air of the outer shell or can be increased by the introduction of steam. Two rooms provide much greater

We investigate how the distance and relative orientation (with respect to their optical axes) between the objects affect the heat flux. In particular, we show that by changing the angle between the optical axes it is possible in certain cases to modulate the net heat flux up to 90% at room temperature, and discuss possible applications of such a strong effect.

Renewable energy has political support, room to grow  

Science Conference Proceedings (OSTI)

Renewable energy sources enjoy growing political support and have plenty of room to grow in the worldwide energy mix. And grow they will, according to most projections. The US Energy Information Administration`s (EIA`s) International Energy Outlook 1997 says consumption of hydroelectricity and other renewables will increase by 56% during 1995--2015. The renewable share of the total energy mix will remain at about current levels, however. The EIA projection includes only renewable fuels used in the generation of electricity. It therefore excludes most biomass energy. Despite the importance of biomass energy, data on consumption of it are sparse. IEA estimates that in the industrialized world, the biomass share of primary energy consumption amounts to 3.5%. Also excluded from EIA`s projection because of insufficiency of data are dispersed renewables, a category that includes energy consumed at the site of production, such as solar panels used for water heating. This paper discusses regional trends, North American activity, Western Europe, Asian developments, and the rest of the world.

The work was initiated to find a replacement material for the 2 Kelvin low power waveguide Higher Order Mode (HOM) absorbers employed within the original cavity cryomodules of the Continuous Electron Beam Accelerator Facility (CEBAF). This effort eventually led to suitable candidates as reported in this paper. Furthermore, though constrained by small funds for labor and resources, we have analyzed a variety of lossy ceramic materials, several of which could be usable as HOM absorbers for both normal conducting and superconducting RF structures, e.g. as loads in cavity waveguides and beam tubes either at room or cryogenic temperatures and, depending on cooling measures, low to high operational power levels.

Ductless, Mini-Split Heat Pumps Ductless, Mini-Split Heat Pumps Ductless, Mini-Split Heat Pumps June 24, 2012 - 4:19pm Addthis What does this mean for me? You can take advantage of the fact that -- unlike earlier versions -- newer models of ductless mini-split heat pumps operate effectively in cold temperatures. If you are building an addition or doing a major remodel and your home does not have heating and cooling ducts, a ductless mini-split heat pump may be a cost-effective, energy-efficient choice. Ductless, mini-split-system heat pumps (mini splits) make good retrofit add-ons to houses with "non-ducted" heating systems, such as hydronic (hot water heat), radiant panels, and space heaters (wood, kerosene, propane).

Thermoeconomic Analysis of a Solar Heat-Pump System  

E-Print Network (OSTI)

This paper introduces a solar energy heat-pump system and analyzes the thermoeconomics. The results show that the solar energy heat-pump system can be operated in different modes and used for room heating in winter and cooling in summer and/or heating a hot water supply. The results also show that the efficiency of the system's components and how the investment costs greatly affect the wide acceptability and use of the system. Solar energy is clean and renewable and having not to pay the solar energy costs, the solar energy heat-pump system is still attractive and will have a large market.

HEAT GENERATION  

DOE Patents (OSTI)

Heat is generated by the utilization of high energy neutrons produced as by nuclear reactions between hydrogen isotopes in a blanket zone containing lithium, a neutron moderator, and uranium and/or thorium effective to achieve multtplicatton of the high energy neutron. The rnultiplied and moderated neutrons produced react further with lithium-6 to produce tritium in the blanket. Thermal neutron fissionable materials are also produced and consumed in situ in the blanket zone. The heat produced by the aggregate of the various nuclear reactions is then withdrawn from the blanket zone to be used or otherwise disposed externally. (AEC)

Electrorecovery of actinides at room temperature  

Science Conference Proceedings (OSTI)

There are a large number of purification and processing operations involving actinide species that rely on high-temperature molten salts as the solvent medium. One such application is the electrorefining of impure actinide metals to provide high purity material for subsequent applications. There are some drawbacks to the electrodeposition of actinides in molten salts including relatively low yields, lack of accurate potential control, maintaining efficiency in a highly corrosive environment, and failed runs. With these issues in mind we have been investigating the electrodeposition of actinide metals, mainly uranium, from room temperature ionic liquids (RTILs) and relatively high-boiling organic solvents. The RTILs we have focused on are comprised of 1,3-dialkylimidazolium or quaternary ammonium cations and mainly the {sup -}N(SO{sub 2}CF{sub 3}){sub 2} anion [bis(trif1uoromethylsulfonyl)imide {equivalent_to} {sup -}NTf{sub 2}]. These materials represent a class of solvents that possess great potential for use in applications employing electrochemical procedures. In order to ascertain the feasibility of using RTILs for bulk electrodeposition of actinide metals our research team has been exploring the electron transfer behavior of simple coordination complexes of uranium dissolved in the RTIL solutions. More recently we have begun some fundamental electrochemical studies on the behavior of uranium and plutonium complexes in the organic solvents N-methylpyrrolidone (NMP) and dimethylsulfoxide (DMSO). Our most recent results concerning electrodeposition will be presented in this account. The electrochemical behavior of U(IV) and U(III) species in RTILs and the relatively low vapor pressure solvents NMP and DMSO is described. These studies have been ongoing in our laboratory to uncover conditions that will lead to the successful bulk electrodeposition of actinide metals at a working electrode surface at room temperature or slightly elevated temperatures. The RTILs we have focused on thus far are based on 1,3-dialkylimidazolium or quaternary ammonium cations and {sup -}N(SO{sub 2}CF{sub 3}){sub 2} anions. Our results from XPS studies of e1ectrooxidized uranium metal surfaces indicate that uranium metal reacts with the anion from the RTIL, most likely through an initial f1uoride abstraction, forming decomposition products that inhibit the bulk electrodeposition of uranium metal. Similar results were found when the organic solvents were used with TBA[B(C{sub 6}F{sub 5}){sub 4}] as the supporting electrolyte, although the voltammetric data of uranium ions in these solutions is more encouraging in relation to electrodeposition of uranium metal. Preliminary results on the voltammetric behavior and bulk electrodeposition of plutonium species are also presented.

Heat pump/refrigerator using liquid working fluid  

DOE Patents (OSTI)

A heat transfer device is described that can be operated as a heat pump or refrigerator, which utilizes a working fluid that is continuously in a liquid state and which has a high temperature-coefficient of expansion near room temperature, to provide a compact and high efficiency heat transfer device for relatively small temperature differences as are encountered in heating or cooling rooms or the like. The heat transfer device includes a pair of heat exchangers that may be coupled respectively to the outdoor and indoor environments, a regenerator connecting the two heat exchangers, a displacer that can move the liquid working fluid through the heat exchangers via the regenerator, and a means for alternately increasing and decreasing the pressure of the working fluid. The liquid working fluid enables efficient heat transfer in a compact unit, and leads to an explosion-proof smooth and quiet machine characteristic of hydraulics. The device enables efficient heat transfer as the indoor-outdoor temperature difference approaches zero, and enables simple conversion from heat pumping to refrigeration as by merely reversing the direction of a motor that powers the device.

Dehumidifying Heat Pipes Dehumidifying Heat Pipes Dehumidifying Heat Pipes June 24, 2012 - 4:32pm Addthis In order to make a room comfortable in hot, humid climates, an air conditioner must lower the indoor humidity level as well as the air temperature. If an air conditioner fails to lower the humidity adequately, the air will be cool, but will feel uncomfortably damp.

Initial Study of Solar Control Film in a Hotel Guest Room in Winter  

E-Print Network (OSTI)

In recent years, energy-efficient facilities have prevailed in the Hong Kong and China markets. Many of these facilities claim to generate considerable energy and money savings. Hoteliers, however, find that there is a lack of independent and local studies about energy performance and its related financial savings and environmental improvement brought by those facilities, such as heat pumps, solar-control film on the window, sensor and dimmer for lighting control, etc. Nevertheless, there is a lack of reliable and independent data about the energy performance and economic viability of the solar-control film applied in a real environment. In many situations, consumers are only given the laboratory's result of this energy saving facility. Research was carried out in summer to estimate its positive effect on energy saving. There is also a paucity of experiments conducted in winter to show its negative effect in cold weather. This study carries out an experiment in hotel guest rooms in winter in order to estimate the energy and lighting performance of solar-control film in winter. This experiment was conducted when the illuminance under 1000lux, the average visible light transmittance for the film was 49.8%, and with very low solar radiation being transmitted into indoor environment. Under these situations, the study found that the effect of solar energy passing through the film coating in the guest room can be neglected. Instead, the film can act as a layer to prevent heat to transmit to the outdoors, just like the greenhouse effect.

The results show that low concentrations of {sup 133}Xe in room air can be reliably detected and that staff exposure to {sup 133}Xe at this institution was within ICRP recommendations.

How much sense do room occupancy sensor controls make  

SciTech Connect

Hotel operators are faced with a confusing array of both remote and local guest room energy control devices. A wide variety of decentralized electronic room controllers, each with its own control logic and vendor claims are in competition with remote front desk microprocessor controls which are essentially ''blind'' to actual occupancy. This paper is a review of the characteristics of various controllers, their behaviour with different in-room environmental equipment, and guest reactions to the potpourri of available devices.

Heating Facilities, Stepping Stones Rehabilitation Center, Klamath Falls, Oregon.  

DOE Green Energy (OSTI)

The Stepping Stones Rehabilitation Center is leased from Klamath County and operated by the Klamath Council on Alcohol and Drugs. Buildings consist of interconnected and adjoining buildings laid out in a U configuration, with a total floor plan area of about 13,000 square feet. Construction is conventional single story, with tile roofs, masonry facing on the walls, and single glazed windows. Heating is by room wall convectors using low pressure steam. Steam is generated in an oil fired boiler. It is economically feasible to heat Stepping Stones using a water to water heat pump. Low temperature geothermal water from a relatively shallow well would be boosted from 80/sup 0/F to a 150/sup 0/F in the heat pump. This hot water would supply space heating requirements and potable hot water. The existing boiler, steam and condensate piping, and room convectors would be removed. The water to water heat pump, new piping, and room convectors would be installed. Estimated capital cost is $140,000. Annual energy savings in fuel oil purchases is about 26,000 gallons with a first year value of about $19,000. This savings, less operating costs, when applied with escalation considerations over a period of twenty years, results in a present worth of $91,778 when discounted at 10%. This is the amount of surplus generated after the payment of all obligations, when the project is financed with 10% bonds.

Design of a multisystem remote maintenance control room  

SciTech Connect

The Remote Systems Development Section of the Consolidated Fuel Reprocessing Program at the Oak Ridge National Laboratory (ORNL) and Japan's Power Reactor and Nuclear Fuel Development Corporation (PNC) recently collaborated in the development of a control room concept for remote operations. This report describes design methods and the resulting control room concept. The design project included five stages. The first was compilation of a complete function list; functions are tasks performed by operators in the control room while operating equipment located in the remote area. The second step was organization of the function list into ''function groups;'' function groups are sets of functions that operate one piece of equipment. The third stage was determination of crew size and requirements for supervision. The fourth stage was development of conceptual designs of displays and controls. The fifth stage was development of plans for placement of crew stations within the control room. 5 figs., 1 tab.

Using a Research Simulator for Validating Control Room Modernization Concepts  

SciTech Connect

The Light Water Reactor Sustainability Program is a research, development, and deployment program sponsored by the United States Department of Energy. The program is operated in close collaboration with industry research and development programs to provide the technical foundations for licensing and managing the long-term, safe, and economical operation of nuclear power plants that are currently in operation. Advanced instrumentation and control (I&C) technologies are needed to support the continued safe and reliable production of power from nuclear energy systems during sustained periods of operation up to and beyond their expected licensed lifetime. This requires that new capabilities to achieve process control be developed and eventually implemented in existing nuclear control rooms. It also requires that approaches be developed and proven to achieve sustainability of I&C systems throughout the period of extended operation. Idaho National Laboratory (INL) is working closely with nuclear utilities to develop technologies and solutions to help ensure the safe life extension of current reactors. One of the main areas of focus is control room modernization. Current analog control rooms are growing obsolete, and it is difficult for utilities to maintain them. Using its reconfigurable control room simulator adapted from a training simulator, INL serves as a neutral test bed for implementing new control room system technologies and assisting in control room modernization efforts across.

Pilot Study: Measurement of Room Illuminance to Assess Automatic Brightness  

NLE Websites -- All DOE Office Websites (Extended Search)

Study: Measurement of Room Illuminance to Assess Automatic Brightness Study: Measurement of Room Illuminance to Assess Automatic Brightness Control in Televisions Title Pilot Study: Measurement of Room Illuminance to Assess Automatic Brightness Control in Televisions Publication Type Conference Proceedings Year of Publication 2012 Authors Greenblatt, Jeffery B., Mia Forbes Pirie, Louis-Benoit Desroches, Sally M. Donovan, Clancy Donnelly, Craig Billingsley, and Chris Calwell Pagination 13 Date Published August 12 Conference Location Berkeley Abstract Automatic brightness control (ABC) is an increasingly common feature found in newtelevisions (TVs) and computer monitors. ABC is intended to adjust TV screen brightness(luminance) according to the ambient light level (room illuminance). When implementedcorrectly, this can both reduce energy consumption and improve viewing quality. The currentENERGY STAR test procedure provides for a more favorable energy use rating for TVs withABC, by measuring power consumption at two light levels (0 and 300 lux) and reporting aweighted-average energy use. However, this and other studies suggest that these levels are notrepresentative of actual TV viewing conditions.As there were currently only limited data available concerning room illuminance, weundertook a small pilot study in 2011 to begin to answer two key questions: 1. To what extent doroom illuminance levels vary depending on the location of measurement (e.g., center of theroom, on the couch, or at the TV)? 2. What room illuminance conditions are prevalent whenpeople watch TV?We measured room illuminance in the homes of nine volunteers in California andColorado to begin addressing the above two questions. Although the study had the usualdrawbacks of a pilot (limited sample size, time duration, etc.), it has, nonetheless, yielded usefulresults. The study shows definitively that there is large variability between measurements madeat different locations in the room and, therefore, that location of room illuminance measurementsis critical. Moreover, the majority (over 75%) of TV viewing occurred at illuminance levels ofless than 50 lux (though measurements of up to several hundred lux were also recorded), a resultthat was consistent with subsequent larger-scale studies. This type of information can helpdetermine how ABC-enabled TVs should be tested to best represent actual viewing conditions.

Solar-assisted electric clothes dryer using a home attic as a heat source  

DOE Green Energy (OSTI)

This study was undertaken to determine the suitability of using a southeastern home attic as a means of reducing the energy consumption of an electric clothes dryer. An inexpensive duct (duplicable for $25) was constructed to collect hot attic air from the peak of a south facing roof and introduce it into the dryer inlet. Instrumentation was added to measure inlet temperatures and operating time/energy consumption of the dryer. Standardized test loads, in addition to normal laundry, were observed over the period of one year. The heat-on time of the dryer tested was shown to be reduced .16 to .35 minutes per /sup 0/C rise in inlet temperature. Inlet temperatures produced by the attic duct peaked at 56/sup 0/C(133/sup 9/F) in May/June and 40/sup 0/C(104/sup 0/F) in February. Based on peak temperatures available between 2 and 4 pm each month, a potential 20% yearly average savings could be realized. Economic viability of the system, dependant primarily on dryer usage, can be computed using a formula derived from the test results and included in the report.

Over 3,000 such heat exchangers are now in service, recovering an estimated energy equivalent of nearly 1.1 million barrels of oil annually. Energy recovered by these units has been used to either preheat process supply air or to heat plant comfort make-up air. Heat pipe heat exchangers have been applied to an ever-expanding variety of industrial processes. One notable application in recent years has been for combustion airs preheat of fired heaters in petroleum refineries and petrochemical plants. Another recent development has been a waste heat recovery boiler using heat pipes. This device has a number of advantageous features. Field operational experience of several units in service has been excellent.

Thermal Energy Corporation Combined Heat and Power Project  

Science Conference Proceedings (OSTI)

To meet the planned heating and cooling load growth at the Texas Medical Center (TMC), Thermal Energy Corporation (TECO) implemented Phase 1 of a Master Plan to install an additional 32,000 tons of chilled water capacity, a 75,000 ton-hour (8.8 million gallon) Thermal Energy Storage (TES) tank, and a 48 MW Combined Heat and Power (CHP) system. The Department of Energy selected TMC for a $10 million grant award as part of the Financial Assistance Funding Opportunity Announcement, U.S. Department of Energy National Energy Technology, Recovery Act: Deployment of Combined Heat and Power (CHP) Systems, District Energy Systems, Waste Energy Recovery Systems, and Efficiency Industrial Equipment Funding Opportunity Number: DE-FOA-0000044 to support the installation of a new 48 MW CHP system at the TMC located just outside downtown Houston. As the largest medical center in the world, TMC is home to many of the nation??s best hospitals, physicians, researchers, educational institutions, and health care providers. TMC provides care to approximately six million patients each year, and medical instruction to over 71,000 students. A medical center the size of TMC has enormous electricity and thermal energy demands to help it carry out its mission. Reliable, high-quality steam and chilled water are of utmost importance to the operations of its many facilities. For example, advanced medical equipment, laboratories, laundry facilities, space heating and cooling all rely on the generation of heat and power. As result of this project TECO provides this mission critical heating and cooling to TMC utilizing a system that is both energy-efficient and reliable since it provides the capability to run on power independent of the already strained regional electric grid. This allows the medical center to focus on its primary mission ?? providing top quality medical care and instruction ?? without worrying about excessive energy costs or the loss of heating and cooling due to the risk of power outages. TECO??s operation is the largest Chilled Water District Energy System in the United States. The company used DOE??s funding to help install a new high efficiency CHP system consisting of a Combustion Turbine and a Heat Recovery Steam Generator. This CHP installation was just part of a larger project undertaken by TECO to ensure that it can continue to meet TMC??s growing needs. The complete efficiency overhaul that TECO undertook supported more than 1,000 direct and indirect jobs in manufacturing, engineering, and construction, with approximately 400 of those being jobs directly associated with construction of the combined heat and power plant. This showcase industrial scale CHP project, serving a critical component of the nation??s healthcare infrastructure, directly and immediately supported the energy efficiency and job creation goals established by ARRA and DOE. It also provided an unsurpassed model of a district energy CHP application that can be replicated within other energy intensive applications in the industrial, institutional and commercial sectors.

Energy Savings in Buildings Using Air Movement and Allowing Floating Temperature in Rooms  

E-Print Network (OSTI)

The purpose of the research study was to determine if building loads could be reduced by using an intelligent controller rather than a thermostatic controller to operate heating and air conditioning equipment. In order to switch the equipment on and off at the proper times, the intelligent controller calculated temperature limits using a mathematical procedure that determined the percentage of people who would be comfortable in rooms of the building. Simulations showed the annual cost savings from intelligent controllers ranged from 6 to 37 percent for residences and from 6 to 29 percent for the offices. An ancillary study showed that a ceiling fan provided comfort in a 112 square foot floor area to 85 F and in a 200 to 250 square foot area to 82 F.

Information Foraging in Nuclear Power Plant Control Rooms  

SciTech Connect

nformation foraging theory articulates the role of the human as an 'informavore' that seeks information and follows optimal foraging strategies (i.e., the 'information scent') to find meaningful information. This paper briefly reviews the findings from information foraging theory outside the nuclear domain and then discusses the types of information foraging strategies operators employ for normal and off-normal operations in the control room. For example, operators may employ a predatory 'wolf' strategy of hunting for information in the face of a plant upset. However, during routine operations, the operators may employ a trapping 'spider' strategy of waiting for relevant indicators to appear. This delineation corresponds to information pull and push strategies, respectively. No studies have been conducted to determine explicitly the characteristics of a control room interface that is optimized for both push and pull information foraging strategies, nor has there been empirical work to validate operator performance when transitioning between push and pull strategies. This paper explores examples of control room operators as wolves vs. spiders and con- cludes by proposing a set of research questions to investigate information foraging in control room settings.

Heating facilities: Klamath Lutheran Church, Klamath Falls, Oregon  

DOE Green Energy (OSTI)

The Klamath Lutheran Church is a masonry structure with cathedral ceiling containing approximately 5800 sq ft of floor area. This building is currently heated by two duct furnaces and a unit heater all of which are gas fired. An Educational Wing of approximately 6300 sq ft was added in 1958. This building, containing 2 assembly rooms and a number of classrooms is of uninsulated frame construction, with extensive glass area. A gas-fired boiler supplying finned tube radiators currently heats this wing. Four specific options for displacing all or part of the heating duty with geothermal were examined. These options are: case 1 - drilling a production and injection well on the property and using the resultant hot water (180/sup 0/F) to heat the entire facility; case 3 - using effluent from the Klamath Union High School to heat the entire facility; no well drilling required; case 2 - using effluent from the Klamath Union High School to heat only the church building; the present gas boiler would heat the Educational Wing; and case 4 - drilling a production and injection well on the property and using the resulting water (70/sup 0/F) to supply a water-to-water heat pump. Of the four cases examined, case 3 (heating of both the church building and educational wing with effluent from the Klamath Union High School) seems to offer the greatest potential and earliest simple payback period.

Revzan, Toshifumi Hotchi, Alfred T. Hodgson, and Nancy J. Brown Journal Atmospheric Environment Volume 38 Start Page Chapter Issue 16 Pagination 2483-2494 Abstract We present experimental data and semi-empirical models describing the sorption of organic gases in a simulated indoor residential environment. Two replicate experiments were conducted with 20 volatile organic compounds (VOCs) in a 50-m3 room finished with painted wallboard, carpet and cushion, draperies and furnishings. The VOCs span a wide volatility range and include ten Hazardous Air Pollutants. VOCs were introduced to the static chamber as a pulse and their gas-phase concentrations were measured during a net adsorption period and a subsequent net desorption period. Three sorption models were fit to the measured concentrations for each compound to determine the simplest formulation needed to adequately describe the observed behavior. Sorption parameter values were determined by fitting the models to adsorption period data then checked by comparing measured and predicted behavior during desorption. The adequacy of each model was evaluated using a goodness of fit parameter calculated for each period. Results indicate that sorption usually does not greatly affect indoor concentrations of methyl-tert-butyl ether, 2-butanone, isoprene and benzene. In contrast, sorption appears to be a relevant indoor process for many of the VOCs studied, including C8-C10 aromatic hydrocarbons (HC), terpenes, and pyridine. These compounds sorbed at rates close to typical residential air change rates and exhibited substantial sorptive partitioning at equilibrium. Polycyclic aromatic HCs, aromatic alcohols, ethenylpyridine and nicotine initially adsorbed to surfaces at rates of 1.5 to >6 h-1 and partitioned 95 to >99% in the sorbed phase at equilibrium

Determination of the Acceptable Room Temperature Range for Local Cooling  

E-Print Network (OSTI)

Determination of the acceptable room temperature range is a key problem in satisfactory design of local cooling for energy savings. At the room temperatures ranging from neutral to warm, three sensitive body parts-the face, chest and back-were each exposed to local cooling airflow, where temperatures were 22, 25 and 28C. Thirty randomly-selected male subjects, dressed in shorts, were exposed to each condition for 30 minutes. Data were collected on their local thermal sensations of each body part, overall thermal sensation, and overall thermal acceptability on voting scales at regular intervals during the exposure. Results show that the non-uniformity of thermal sensation is a key factor affecting thermal acceptability except for overall thermal sensation. A new assessment model for local cooling was proposed. The model shows that face cooling can improve thermal acceptability more than chest or back cooling, and the upper boundary of the acceptable range of room temperature can be shifted from 26C to 30.5C when face cooling is provided.

Chemical heat pump  

DOE Patents (OSTI)

A chemical heat pump system is disclosed for use in heating and cooling structures such as residences or commercial buildings. The system is particularly adapted to utilizing solar energy, but also increases the efficiency of other forms of thermal energy when solar energy is not available. When solar energy is not available for relatively short periods of time, the heat storage capacity of the chemical heat pump is utilized to heat the structure as during nighttime hours. The design also permits home heating from solar energy when the sun is shining. The entire system may be conveniently rooftop located. In order to facilitate installation on existing structures, the absorber and vaporizer portions of the system may each be designed as flat, thin wall, thin pan vessels which materially increase the surface area available for heat transfer. In addition, this thin, flat configuration of the absorber and its thin walled (and therefore relatively flexible) construction permits substantial expansion and contraction of the absorber material during vaporization and absorption without generating voids which would interfere with heat transfer. The heat pump part of the system heats or cools a house or other structure through a combination of evaporation and absorption or, conversely, condensation and desorption, in a pair of containers. A set of automatic controls change the system for operation during winter and summer months and for daytime and nighttime operation to satisfactorily heat and cool a house during an entire year. The absorber chamber is subjected to solar heating during regeneration cycles and is covered by one or more layers of glass or other transparent material. Daytime home air used for heating the home is passed at appropriate flow rates between the absorber container and the first transparent cover layer in heat transfer relationship in a manner that greatly reduce eddies and resultant heat loss from the absorbant surface to ambient atmosphere.

Heating facilities for the city schools, Ephrata, Washington  

DOE Green Energy (OSTI)

The City of Ephrata, Washington has an existing well that has the capability of pumping 2200 gallons per minute of 86/sup 0/F water into the City drinking water system. To determine the economic practicality of using the City water to heat the schools, one school (Middle School) was selected for evaluation. Two cases were considered. Case 1 uses a two stage water-to-water heat pump to produce a 190/sup 0/F circulating hot water steam. This would be compatible with the existing system and essentially no retrofit costs for the room convective heating system would be incurred. Case 2 uses a single stage water-to-water heat pump to produce a 140/sup 0/F circulating hot water stream. Retrofit costs would incur for additional room convection equipment. In both cases the heat pump is sized to furnish the total heating and hot water requirements of the school. However, one of the existing boilers is left in place to serve as standby. The Middle School evaluation shows the single stage heat pump to be most cost effective, having a return on invested capital of about 19%. Projecting the single stage evaluation to include all the schools, the total conversion cost would be about $800,000. This includes a retrofit allowance of $100,000. The return on investment would be about 19%. Total annual savings in fuel oil consumption would be nearly 150,000 gallons, amounting to a first year savings of about $134,000. Peak water usage would be 1000 gallons per minute, about 45% of that available. Annual water usage would be about 90 million gallons, about 14% of the water used during 1978. This water would be returned to the drinking water system after extraction of heat. (MHR)

Heat transfer in freeboard region of fluidized beds  

SciTech Connect

This research involved the study of heat transfer and fluid mechanic characteristics around a horizontal tube in the freeboard region of fluidized beds. Heat transfer coefficients were experimetnally measured for different bed temperatures, particle sizes, gas flow rates, and tube elevations in the freeboard region of air fluidized beds at atmospheric pressure. Local heat transfer coefficients were found to vary significantly with angular position around the tube. Average heat transfer coefficients were found to decrease with increasing freeboard tube elevation and approach the values for gas convection plus radiation for any given gas velocity. For a fixed tube elevation, heat transfer coefficients generally increased with increasing gas velocity and with high particle entrainment they can approach the magnitudes found for immersed tubes. Heat transfer coefficients were also found to increase with increasing bed temperature. It was concluded that this increase is partly due to increase of radiative heat transfer and partly due to change of thermal properties of the fluidizing gas and particles. To investigate the fluid mechanic behavior of gas and particles around a freeboard tube, transient particle tube contacts were measured with a special capacitance probe in room temperature experiments. The results indicated that the tube surface experiences alternating dense and lean phase contacts. Quantitative information for local characteristics was obtained from the capacitance signals and used to develop a phenomenological model for prediction of the heat transfer coefficients around freeboard tubes. The packet renewal theory was modified to account for the dense phase heat transfer and a new model was suggested for the lean phase heat transfer. Finally, an empirical freeboard heat transfer correlation was developed from functional analysis of the freeboard heat transfer data using nondimensional groups representing gas velocity and tube elevation.

Absorption heat pump system  

DOE Patents (OSTI)

An improvement in an absorption heat pump cycle is obtained by adding adiabatic absorption and desorption steps to the absorber and desorber of the system. The adiabatic processes make it possible to obtain the highest temperature in the absorber before any heat is removed from it and the lowest temperature in the desorber before heat is added to it, allowing for efficient utilization of the thermodynamic availability of the heat supply stream. The improved system can operate with a larger difference between high and low working fluid concentrations, less circulation losses, and more efficient heat exchange than a conventional system.

DOE Patents (OSTI)

A heat pump apparatus including a compact arrangement of individual tubular reactors containing hydride-dehydride beds in opposite end sections, each pair of beds in each reactor being operable by sequential and coordinated treatment with a plurality of heat transfer fluids in a plurality of processing stages, and first and second valves located adjacent the reactor end sections with rotatable members having multiple ports and associated portions for separating the hydride beds at each of the end sections into groups and for simultaneously directing a plurality of heat transfer fluids to the different groups. As heat is being generated by a group of beds, others are being regenerated so that heat is continuously available for space heating. As each of the processing stages is completed for a hydride bed or group of beds, each valve member is rotated causing the heat transfer fluid for the heat processing stage to be directed to that bed or group of beds. Each of the end sections are arranged to form a closed perimeter and the valve member may be rotated repeatedly about the perimeter to provide a continuous operation. Both valves are driven by a common motor to provide a coordinated treatment of beds in the same reactors. The heat pump apparatus is particularly suitable for the utilization of thermal energy supplied by solar collectors and concentrators but may be used with any source of heat, including a source of low-grade heat.

Switchable heat pipe assembly  

SciTech Connect

The heat pipe assembly is formed into an H-shape or a Y-shape. The H-shaped configuration comprises two heat pipes, each having condenser and evaporator sections with wicking therein coupled by a tube with wick at their evaporator sections. The Y-shaped configuration utilizes a common evaporator section in place of the two evaporator sections of the H-shaped configuration. In both configurations, the connection between the vapor spaces of the two heat pipes equalizes vapor pressure within the heat pipes. Although both heat pipes have wicks, they have sufficient fluid only to saturate a single pipe. If heat is applied to the condenser section of one of the pipes, this heat pipe becomes inoperative since all the fluid is transferred to the second pipe which can operate with a lower thermal load.

Method for heat treating and sintering metal oxides with microwave radiation  

DOE Patents (OSTI)

A method for microwave sintering materials, primarily metal oxides, is described. Metal oxides do not normally absorb microwave radiation at temperatures ranging from about room temperature to several hundred degrees centrigrade are sintered with microwave radiation without the use of the heretofore required sintering aids. This sintering is achieved by enclosing a compact of the oxide material in a housing or capsule formed of a oxide which has microwave coupling properties at room temprature up to at least the microwave coupling temperature of the oxide material forming the compact. The heating of the housing effects the initial heating of the oxide material forming the compact by heat transference and then functions as a thermal insulator for the encased oxide material after the oxide material reaches a sufficient temperature to adequately absorb or couple with microwave radiation for heating thereof to sintering temperature.

Heat pipe technology issues  

SciTech Connect

Critical high temperature, high power applications in space nuclear power designs are near the current state of the art of heat pipe technology in terms of power density, operating temperature, and lifetime. Recent heat pipe development work at Los Alamos National Laboratory has involved performance testing of typical space reactor heat pipe designs to power levels in excess of 19 kW/cm/sup 2/ axially and 300 W/cm/sup 2/ radially at temperatures in the 1400 to 1500 K range. Operation at conditions in the 10 kW/cm/sup 2/ range has been sustained for periods of up to 1000 hours without evidence of performance degradation. The effective length for heat transport in these heat pipes was from 1.0 to 1.5 M. Materials used were molybdenum alloys with lithium employed as the heat pipe operating fluid. Shorter, somewhat lower power, molybdenum heat pipes have been life tested at Los Alamos for periods of greater than 25,000 hours at 1700 K with lithium and 20,000 hours at 1500/sup 0/K with sodium. These life test demonstrations and the attendant performance limit investigations provide an experimental basis for heat pipe application in space reactor design and represent the current state-of-the-art of high temperature heat pipe technology.

Heat transfer dynamics  

Science Conference Proceedings (OSTI)

As heat transfer technology increases in complexity, it becomes more difficult for those without thermal dynamics engineering training to choose between competitive heat transfer systems offered to meet their drying requirements. A step back to the basics of heat transfer can help professional managers and papermakers make informed decisions on alternative equipment and methods. The primary forms of heat and mass transfer are reviewed with emphasis on the basics, so a practical understanding of each is gained. Finally, the principles and benefits of generating infrared energy by combusting a gaseous hydrocarbon fuel are explained.

Observation of visible luminescence from indium nitride at room temperature  

SciTech Connect

InN films were grown on sapphire substrates with AlN buffer layers by reactive sputtering. C-axis-oriented crystalline InN films with a wurtzite structure were confirmed by x-ray diffraction and Raman scattering. Strong photoluminescence (PL) at 1.87 eV, together with a clear absorption edge at 1.97 eV, was observed at room temperature, which clearly demonstrates that it is not accurate in the previous assignment of an {approx}0.7 eV fundamental band gap for intrinsic InN simply from PL and absorption data. The possible origin of the present large band gap was discussed in terms of the effects of oxygen and the Burstein-Moss shift.

Generation of coherent terahertz pulses in ruby at room temperature  

Science Conference Proceedings (OSTI)

We have shown that a coherently driven solid state medium can potentially produce strong controllable short pulses of THz radiation. The high efficiency of the technique is based on excitation of maximal THz coherence by applying resonant optical pulses to the medium. The excited coherence in the medium is connected to macroscopic polarization coupled to THz radiation. We have performed detailed simulations by solving the coupled density matrix and Maxwell equations. By using a simple V-type energy scheme for ruby, we have demonstrated that the energy of generated THz pulses ranges from hundreds of pico-Joules to nano-Joules at room temperature and micro-Joules at liquid helium temperature, with pulse durations from picoseconds to tens of nanoseconds. We have also suggested a coherent ruby source that lases on two optical wavelengths and simultaneously generates THz radiation. We discussed also possibilities of extension of the technique to different solid-state materials.

COMMERCIAL UTILITY PERSPECTIVES ON NUCLEAR POWER PLANT CONTROL ROOM MODERNIZATION  

SciTech Connect

Commercial nuclear power plants (NPPs) in the United States need to modernize their main control rooms (MCR). Many NPPs have done partial upgrades with some success and with some challenges. The Department of Energys (DOE) Light Water Reactor Sustainability (LWRS) Program, and in particular the Advanced Instrumentation and Controls (I&C) and Information Systems Technologies Research and Development (R&D) Pathway within LWRS, is designed to assist commercial nuclear power industry with their MCR modernization efforts. As part of this framework, a survey was issued to utility representatives of the LWRS Program Advanced Instrumentation, Information, and Control Systems/Technologies (II&C) Utility Working Group to obtain their views on a range of issues related to MCR modernization, including: drivers, barriers, and technology options, and the effects these aspects will have on concepts of operations, modernization strategies, and staffing. This paper summarizes the key survey results and discusses their implications.

200-GeV ISA with room temperature magnets  

SciTech Connect

A conceptual design study of 200-GeV proton intersecting storage accclerators with room temperature magnets is presented. The key to this study was thc desire to keep the electric power consumptiom to an acceptable level (40 MW). The design has been optimized by choosing small-gap (4 cm) aluminum coil dipoles operating at about 15 kG. The luminosity of this machine is limited to about 10/sup 32/ cm-/sup -2/ sec/sup -1/ by transverse space-charg e effects. An order of magnitude higher luminositics can be obtained by adding a booster of modest cost. A novel vacuum system using distributed Ti-sublimation pumps results in considerable savings. A cost comparison with a high-luminosity superconducting machine is given. (auth)

Heat Pipe Integrated Microsystems  

SciTech Connect

The trend in commercial electronics packaging to deliver ever smaller component packaging has enabled the development of new highly integrated modules meeting the demands of the next generation nano satellites. At under ten kilograms, these nano satellites will require both a greater density electronics and a melding of satellite structure and function. Better techniques must be developed to remove the subsequent heat generated by the active components required to-meet future computing requirements. Integration of commercially available electronics must be achieved without the increased costs normally associated with current generation multi chip modules. In this paper we present a method of component integration that uses silicon heat pipe technology and advanced flexible laminate circuit board technology to achieve thermal control and satellite structure. The' electronics/heat pipe stack then becomes an integral component of the spacecraft structure. Thermal management on satellites has always been a problem. The shrinking size of electronics and voltage requirements and the accompanying reduction in power dissipation has helped the situation somewhat. Nevertheless, the demands for increased onboard processing power have resulted in an ever increasing power density within the satellite body. With the introduction of nano satellites, small satellites under ten kilograms and under 1000 cubic inches, the area available on which to place hot components for proper heat dissipation has dwindled dramatically. The resulting satellite has become nearly a solid mass of electronics with nowhere to dissipate heat to space. The silicon heat pipe is attached to an aluminum frame using a thermally conductive epoxy or solder preform. The frame serves three purposes. First, the aluminum frame provides a heat conduction path from the edge of the heat pipe to radiators on the surface of the satellite. Secondly, it serves as an attachment point for extended structures attached to the satellite such as solar panels, radiators, antenna and.telescopes (for communications or sensors). Finally, the packages make thermal contact to the surface of the silicon heat pipe through soft thermal pads. Electronic components can be placed on both sides of the flexible circuit interconnect. Silicon heat pipes have a number of advantages over heat pipe constructed from other materials. Silicon heat pipes offer the ability to put the heat pipe structure beneath the active components of a processed silicon wafer. This would be one way of efficiently cooling the heat generated by wafer scale integrated systems. Using this technique, all the functions of a satellite could be reduced to a few silicon wafers. The integration of the heat pipe and the electronics would further reduce the size and weight of the satellite.

Chemical heat pump  

DOE Patents (OSTI)

A chemical heat pump system is disclosed for use in heating and cooling structures such as residences or commercial buildings. The system is particularly adapted to utilizing solar energy, but also increases the efficiency of other forms of thermal energy when solar energy is not available. When solar energy is not available for relatively short periods of time, the heat storage capacity of the chemical heat pump is utilized to heat the structure, as during nighttime hours. The design also permits home heating from solar energy when the sun is shining. The entire system may be conveniently rooftop located. In order to faciliate installation on existing structures, the absorber and vaporizer portions of the system may each be designed as flat, thin wall, thin pan vessels which materially increase the surface area available for heat transfer. In addition, this thin, flat configuration of the absorber and its thin walled (and therefore relatively flexible) construction permits substantial expansion and contraction of the absorber material during vaporization and absorption without generating voids which would interfere with heat transfer.

Water heater heat reclaimer  

SciTech Connect

This invention relates to the conservation of energy in a domestic gas water heater by utilizing the hot exhaust gases in a gas water heater for the preheating of the incoming unheated water into the water heater. The exhaust gases from a domestic gas water heater carry wasted heat and the present invention provides a mean to reclaim part of the wasted heat for the preheating of the incoming unheated water during hot water usage periods. During non hot water usage periods the heat in the exhaust gases is not reclaimed to prevent overheating of the water and also to prevent the formation of water deposit in the preheating assembly or heat reclaimer. During the non hot water usage periods the heat produced in the water heater is normally needed only to maintain the desired water temperature of the stored water in the water tank of the water heater. Due to the rapid heating or recovery rate, the present invention enables the use of a smaller water heater. The use of a smaller water heater reduces the normal heat loss from the stored hot water thereby further reduces energy consumption.

Thermally activated heat pumps  

SciTech Connect

This article describes research to develop efficient gas-fired heat pumps heat and cool buildings without CFCs. Space heating and cooling use 46% of all energy consumed in US buildings. Air-conditioning is the single leading cause of peak demand for electricity and is a major user of chlorofluorocarbons (CFCs). Advanced energy conversion technology can save 50% of this energy and eliminate CFCs completely. Besides saving energy, advanced systems substantially reduce emissions of carbon dioxide (a greenhouse gas), sulfur dioxide, and nitrogen oxides, which contribute to smog and acid rain. These emissions result from the burning of fossil fuels used to generate electricity. The Office of Building Technologies (OBT) of the US Department of Energy supports private industry`s efforts to improve energy efficiency and increase the use of renewable energy in buildings. To help industry, OBT, through the Oak Ridge National Laboratory, is currently working on thermally activated heat pumps. OBT has selected the following absorption heat pump systems to develop: generator-absorber heat-exchange (GAX) cycle for heating-dominated applications in residential and light commercial buildings; double-condenser-coupled (DCC) cycle for commercial buildings. In addition, OBT is developing computer-aided design software for investigating the absorption cycle.

Integrating preconcentrator heat controller  

DOE Patents (OSTI)

A method and apparatus for controlling the electric resistance heating of a metallic chemical preconcentrator screen, for example, used in portable trace explosives detectors. The length of the heating time-period is automatically adjusted to compensate for any changes in the voltage driving the heating current across the screen, for example, due to gradual discharge or aging of a battery. The total deposited energy in the screen is proportional to the integral over time of the square of the voltage drop across the screen. Since the net temperature rise, .DELTA.T.sub.s, of the screen, from beginning to end of the heating pulse, is proportional to the total amount of heat energy deposited in the screen during the heating pulse, then this integral can be calculated in real-time and used to terminate the heating current when a pre-set target value has been reached; thereby providing a consistent and reliable screen temperature rise, .DELTA.T.sub.s, from pulse-to-pulse.
