The new refrigerant fluid R-123 (see Table A.2) is used in a refrigeration system that operates in the ideal refrigeration cycle, except the compressor is neither reversible nor adiabatic. Saturated vapor at -26.5C enters the compressor and superheated vapor exits at 65C. Heat is rejected from the compressor as 1 kW and the R-123 flow rate is 0.1 kg/s. Saturated liquid exits the condenser at 37.5C. Specific heat for R-123 is Cp =0.6 kJ/kg. Find the coefficient of performance.
