Question:
A refrigerator runs on the vapor-compression cycle. The boiler operates at T = 265 K and the condenser operates at 305 K. The compressor has an efficiency of 85%. Thermodynamic data for two different refrigerants is located in Appendix F.
A. What is the maximum attainable coefficient of performance for Freon® 22?
B. What is the maximum attainable coefficient of performance for refrigerant HFC-134a?
C. Besides coefficient of performance, two considerations in choosing a refrigerant are price and safety. Research Freon® 22 and HFC-134a and comment on their suitability as refrigerants.
