Determine coefficient of performance for this refrigerator

Assignment Help Mechanical Engineering
Reference no: EM13711721

Consider a refrigerator that accepts 15 kW of heat in the evaporator and rejects 19.76 kW of heat from the condenser. The compressor requires an input of 5 kW of power and loses 0.24 kW of heat. Determine the coefficient of performance for this refrigerator.

A detailed solution will be greatly appreciated.
