18 C at a rate of 0.25 kg/s and leaves at 26C. The refrigerant enters the condenser at 1.2 MPa and 50°C and leaves at the same pressure sub cooled by 5°C. It the compressor consumes 3.3 kW of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, () the COP, and () the minimum power input to the compressor for the same refrigeration load.
