Problem 1: A refrigerated compartment is maintained at a temperature of -5 °C. Heat from the surroundings, at 25 °C, leaks into the compartment at a rate of 1.2 kW. Find the compressor power required to maintain the temperature difference for the following scenarios: a. The refrigeration cycle is a Carnot cycle. The high temperature reservoir can be taken to be that of the surroundings. b. The refrigeration cycle has a coefficient of performance (COP) equal to half that of the Carnot value.
