1. A food compartment is kept at -12°C by a refrigerator in an environment at 30° C. The total heat transfer to the food compartment is estimated to be 3300 kJ/hr and the heat rejection in the condenser is 4800 kJ/hr. Determine the power input to the compressor, in kW, and the COP of the refrigerator. 30°C 800 kJ/h in 3300 kJ/h -12°C
