Low-GWP Refrigerant Evaluation in AC Systems for High Ambient Temperature Applications - Literature Survey for Impact of Varying Refrigerant Charge on AC System Performance

Technical Report Shen, Bo

The report summarizes the findings of ASHRAE Research project 1173, by Purdue University to assess the impact of varying refrigerant charge on air conditioner (AC) system performance. This project tested six residential air conditioners with varying the system charge in a wide range, using TXV or fixed-orifice as the expansion device. In summary, the systems using fixed-orifices are much more sensitive to reduction of the system charge than using TXVs. The systems using fixed-orifices had noticeable performance degradations when reducing the system charge below 90% relative to the factory charge; the systems using TXVs experienced drastic performance penalties when decreasingmore »« less

Low-GWP Refrigerant Evaluation in AC Systems for High Ambient Temperature Applications – Acquire Nortek Residential AC/HP Units for Evaluation and Model the Units Using HPDM

Technical Report Shen, Bo

For the upcoming refrigerant transition from HFCs to minorly flammable HFO refrigerants (A2L), refrigerant charge reduction is important to mitigate the fire hazard. Microchannel heat exchangers (MHXs) are a mature technology, which is effective in reducing system charge while maintaining similar heat transfer performance. MHXs will be applied more widely when the new refrigerants are used. Prior studies of the A2L HFO blends were mostly focused on fin-and-tube coils (FTC). An in-depth study for an air conditioner (AC)/heat pump (HP) system using all microchannel heat exchangers is still lacking. In FY19, a side-to-side comparison will be conducted between two residentialmore »« less

Low-GWP Refrigerant Evaluation in AC Systems for High Ambient Temperature Applications - Design and Simulation Practice to Identify Charge Reduction Opportunities for Residential AC/HP Units

Technical Report Shen, Bo

Based on three 5-ton, single-speed heat pumps (HPs), using R-410A, which use the same compressor, indoor blower and outdoor fan, the DOE/ORNL Heat Pump Design Model was used to conduct comparative modelling study. Regarding charge reduction opportunities, in general, we recommend: 1. Downsizing the outdoor condenser will reduce the required system charge, i.e. using smaller tube diameters or fewer tubes; reducing the evaporator inner volume is less important; to offset the reduced condenser tube side surface area, one can increase the air side surface area (fin density) or condenser air flow rate via using a more efficient fan. 2. microchannelmore »« less

Comprehensive Compressor Calorimeter Testing of Lower-GWP Alternative Refrigerants for Heat Pump and Medium Temperature Refrigeration Applications

Conference Shrestha, Som S ; Sharma, Vishaldeep ; Abdelaziz, Omar

In response to environmental concerns raised by the use of refrigerants with high Global Warming Potential (GWP), the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has launched an industry-wide cooperative research program, referred to as the Low-GWP Alternative Refrigerants Evaluation Program (AREP), to identify and evaluate promising alternative refrigerants for major product categories. This paper reports one of the Oak Ridge National Laboratory (ORNL) contributions to AREP. It compares performance of alternative refrigerants to that of R-410A and R-404A for heat pump and medium temperature applications, respectively. The alternatives reported in this paper are: R-32, DR-5, and L-41a for R-410A andmore »« less
Low global warming potential (GWP) refrigerant supermarket refrigeration system modeling and its application

Journal Article Sun, Jian ; Kuruganti, Teja ; Munk, Jeffrey ; ... - International Journal of Refrigeration

As an environmentally friendly low global warming potential (GWP) refrigerant, Carbon dioxide (CO₂) has continuously gained popularity and research attention as alternative refrigerant for supermarket refrigeration system. In this paper, to fulfill the increasing need of accurate Low-GWP supermarket refrigeration models for development of supervisory level control and optimization strategies, a high fidelity model is developed for CO₂ transcritical supermarket refrigeration system which includes compressor rack of low temperature (LT) compressors and medium temperature (MT) compressors, air-cooled gas cooler, evaporator, expansion valves and other auxiliary equipment. A resistance-capacity model structure is proposed to simulate the display cases. Semi-thermodynamic models aremore »« less
