A refrigerator storage is supplied with 3600 kg of fish at a temperature of 270 C. The fish has to be
cooled to – 230C for preserving it for a long period without deterioration. The cooling takes place
in 10 hours. The specific heat of fish is 2.0 kJ/kg K above freezing point of fish and 0.5 kJ/kg – K
below freezing point of ish which is - 30C. The latent heat of freezing is 230 kJ/kg. What is the
power to drive the plant if the actual COP is half that of the ideal COP?
(a) 30 kW (b) 15 kW (c) 12 kW (d) 6 kW
