. Refrigerant 134a enters the compressor of a refrigerator as superheated vapor at 0.20 MPa at -10°C at a rate of 1.0 kg/s and it leaves at 1.2 MPa and 70°C. The refrigerant is cooled in the condenser to 44°C and 1.15 MPa and it is throttled to 0.12 MPa. Disregarding any heat transfer and pressure drops in the connecting lines between the components, show the cycle on a T-s diagram with respect to saturation lines and determine the following: [MO1, M02, MO3, M04] a. The rate of heat removal from the refrigerated space and the power input to the compressor b. The isentropic efficiency of the compressor c. The COP of the refrigerator
