Refrigerant ammonia enters the compressor of a refrigerator as superheated vapor at 0.14 MPa, -20°C at a rate of 0.04 kg/s, and leaves at 0.8 MPa, 50°C. The refrigerant is cooled in condenser to 0.75 MPa and is throttled to 0.14 MPa. Disregarding any heat transfer and pressure drops in the connecting lines between the components, determine the rate of heat removal from the refrigerated space. kW
