Vapor-Compression Cycle and operates with P1 = 140 kPa and xị at the outlet of the evaporator, and P3 = 800 kPa and x3 = 0 at the outlet of the condenser. Complete a thermodynamic analysis of the system assuming ideal operation of the compressor. Adding an isentropic efficiency of nc = 75% for the compressor, repeat the analysis for the real system. Compare the coefficient of performance for the ideal system versus that of the real system and the Carnot system where TH= 25 °C and Tz = -10 °C. The refrigerator in the diagram below uses R-134a as its working fluid

Transcribed Image Text:The refrigerator in the diagram below uses R-134a as its working fluid
Vapor-Compression Cycle
and operates with P = 140 kPa and x, at the outlet of the evaporator, and P3 = 800 kPa and x3 = 0 at the outlet
of the condenser. Complete a thermodynamic analysis of the system assuming ideal operation of the
compressor. Adding an isentropic efficiency of nc = 75% for the compressor, repeat the analysis for the real
system. Compare the coefficient of performance for the ideal system versus that of the real system and the
Carnot system where TH= 25 °C and TL = -10 °C.
