Title: Integrated gas-fired desiccant dehumidification vapor-compression cooling system for residential application. Phase 2. Final report, December 1987-December 1988

Abstract

Field tests of a residential liquid-desiccant dehumidifier are described. From analysis done in Phase I of this program, a gas-fired boiler for regenerating the desiccant was selected with a one-ton capacity dehumidifier. Three field-experiment units were built. One was installed at a test house in Gaithersburg, Maryland owned by GEOMET Technologies. The second was installed in Atlanta, Georgia, supported by the Atlanta Gas Light Company. The third unit was shipped to Lone Star Gas Company, Forth Worth, Texas, to be installed in 1989. Once startup problems were corrected, the units ran reliably, controlling indoor humidity accurately. The seasonal COP for the Gaithersburg installation was 0.58; for Atlanta the COP was 0.50. By extending the operating periods (typically 5 minutes in these tests), the COP should increase. A manufacturing cost study of the residential dehumidifier showed that a factory cost of $553.62/unit is achieved at 50,000 units/year volume.

  • The development of an air conditioner that uses a liquid-desiccant dehumidifier is described. Three air-conditioning systems that integrate the operation of a conventional vapor-compression system with a liquid-desiccant dehumidifier were first simulated in seasonal performance studies. These studies showed that there was little benefit from attempting to recover reject heat from the vapor-compression system for regenerating the liquid desiccant. The preferred version of the liquid-desiccant dehumidifier was one that used a simple gas-fired boiler for regenerating the desiccant. When added to a conventional vapor-compression air conditioner, this liquid-desiccant system could maintain comfortable humidity levels in the living space for almostmore » the entire cooling season at a modest premium in operating costs.« less
  • A residential liquid desiccant-boosted evaporative cooling system was developed. The major components included a cross-flow heat exchanger, interchange heat exchanger, and brine boiler. The unit measures approximately 64 inch (L) x 46 inch (W) x 49 inch (H). Economic studies using DOE-2 project a large market potential for the system, with Fresno, California, and El Paso, Texas, the top two market areas. Considerable engineering effort must still be carried out before the system can be commercialized. Some of the outstanding issues include the development of a method for mass-producing a low-cost leaktight cross-flow heat exchanger, tests for corrosion in themore » boiler, and the development of system controls.« less
  • A unique, alternative cogeneration system was designed that will provide an industrial or commercial energy user with high-pressure steam and electricity directly from a packaged cogeneration system. The Integrated Gas Engine Vapor Compression System concept includes an engine-generator set and a steam screw compressor that are mechanically integrated with the engine. The gas-fueled engine is ebulliently cooled, thus allowing its water jacket heat to be recovered in the form of low-pressure steam. This steam is then compressed by the steam compressor to a higher pressure, and when combined with the high-pressure steam generated in the engine's exhaust gas boiler itmore » provides the end user with a more useable thermal energy source. Phase 1B of this project was completed in 1986 and consisted primarily of the procurement of equipment and the final design and assembly of a prototype integrated gas-engine vapor-compression system.« less
  • This report describes the results of a field evaluation of state-of-art desiccant dehumidification equipment in Houston, TX. The evaluation demonstrated that comfort control in a quick-service restaurant could be improved dramatically. However, available gas-fired desiccant dehumidification equipment is too expensive, inefficient, and unreliable to be considered for wide application in the restaurant industry. Results of a technical and economic analysis of four HVAC options in four U.S. cities indicated that improved comfort control could be achieved with only a modest increase in operating costs with an advanced system. This, coupled with the economic benefits achieved through lower indoor humidity suchmore » as improved crew performance and reduced maintenance costs, could justify the introduction of an advanced, integrated, HVAC system using desiccant technology which has an installed cost similar to current equipment.« less
  • In Phase II a gas-fired high-temperature regenerative radiant-tube burner system with a 'W' shaped radiant tube was developed. Phase III successfully applied that system to the Surface Combustion, Inc. 'Ultracase' furnace resulting in higher furnace temperatures, heating rates, and higher efficiencies than conventional gas-fired furnaces.
