Question

It is proposed to design a cold storage for maintaining certain vegetables under frozen conditions at -20°C. The ambient temperature in summer is 37°C and the estimated energy transfer as heat into cold storage through the doors, walls and roof is 3 kJ/s. Determine the minimum power required to operate a refrigeration plant for maintaining the cold storage and maximum possible COP of the refrigerator.
