A household refrigerator that has a power input of 500 watts and a COP of 2 is to cool eight large watermelons, 5 kg each, to 10°C. If the watermelons are initially at 20°C, determine how long will take for the refrigerator cool them. The watermelons can be treated as water whose specific heat is 4.2 KJ/kg-K.

A Carnot heat pump is to be used to heat a house and maintain it at 25°C in winter. On a day when the average outdoor temperature remains at about 2°C, the house is estimated to lose heat at a rate of 55,000 kJ/h. If the heat pump consumes 4.8 kW of power while operating, determine how long the heat pump ran on that day.
An air-conditioning system is used to maintain a house at 70°F when the temperature outside is 100°F. The house is gaining heat through the walls and the windows at a rate of 800 Btu/min, and the heat generation rate within the house from people, lights, and appliances amounts to 100 Btu/min. Determine the minimum power input required for this airconditioning system.
