The refrigerated space is required to cool at -25 Degrees C at a rate of 220 g/s and leaves at 23 degrees C. The refrigerant enters the condenser at 45 Degrees C. The inlet state of the compressor is 7000 Pa and -35 degrees C. The compressor is estimated to gain a net heat of 450 W from the surroundings. Determine the COP of the refrigerator, the quality of the refrigerant at the evaporator inlet, and the refrigeration load. If you vary the compressor inlet condition from 7000 Pa to 8000 Pa what are the differences.
