Question
A real heat pump has .02 kg/s of refrigerant R-134a flowing through it and it consumes 3kW of power. The refrigerant is a mixture at 50% quality and 120 kPa entering the evaporator and leaves at 100 kPa and -20 C. The refrigerant enters the condenser at 1.4 MPa and leaves at 1.2 MPa .
Assuming no loss in pressure or temperature in the connecting pipes, determine the Temperature, Pressure, Enthalpy and Entropy at all positions in the cycle, the heat transfer coming in and leaving , the COP of this heat pump, the Isentropic Efficiency of the compressor and the rate of Entropy Generation in the compressor and of the Throttling process.
