Refrigerant R134a enters the compressor of a refrigerator at 0.14 MPa and -10°C at a rate of 0.12 kg/s and leaves it at 0.7 MPa and 50°C. The refrigerant is cooled in the condenser to 24°C and .065 MPa and it is throttled to 0.15 MPa. Disregarding any heat transfer from lines between components, show the cycle on a T-s diagram and determine the heat removed from the refrigerated space, the power input to the compressor, the isentropic efficiency of the compressor and the coefficient of performance of the refrigerator.
