A refrigerator is used to keep the cold space at 5 °C by rejecting 8 kJ/s of heat by the condenser to the outdoor air at 25 °C. If the compressor consumes 3 kJ/s of power, determine i. the rate of heat removed from the cold space (kJ/s), ii. the COP of the refrigerator iii. the minimum power input to the compressor for the same rate of heat removed (kJ/s), and iv. draw the schematic of the refrigerator as a reversed heat engine.
