Performance of environmentally friendly CFC-12 replacements for refrigerator/freezers
1995
The paper presents the capacity and energy consumption of refrigerant replacements for HFC-134a and/or CFC-12 as determined by experimental testing and analysis. Refrigerator/freezer (R/F) tests were run according to the Association of Home Appliance Manufacturer`s testing conditions in an environmental test chamber. The charge was optimized for each refrigerant, and the results were compared to those for HFC-134a and CFC-12. The numerical model and experiment results were compared to verify the model. The paper investigates HFC-245cb/HFC-134 and HFC-134. Computer modeling predicts that these azeotropes will perform similarly to HFC-134a, which has a higher global warming potential than any of the mixtures except HFC-245cb/HFC-134.
