Question

A commercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°C by rejecting waste heat to cooling water that enters the condenser at 18°C at a rate of 0.25 kg/s and leaves a 26°C. The refrigerant enters the condenser at 1.2 MPa and 50°C and leaves at the same pressure subcooled by 5°C. If the compressor consumes 4 kW of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load,(c) the COP, and (d) the minimum power input to the compressor for the same refrigeration load.
