An air conditioner on a hot summer day removes 8 kW of energy from a house at 21?C and pushes energy to the outside, which is at 31?C. The house has a 15 000-kg mass with an average specific heat of 0.95 kJ/kgK. In order to do this, the cold side of the air conditioner is at 5?C and the hot side is at 40?C. The air conditioner (refrigerator) has a COP that is 60% that of a corresponding Carnot refrigerator. Find the actual air conditioner COP, the power required to run the air conditioner, the rate of exergy destruction inside the air conditioner, and the total rate of exergy destruction due to the air conditioner and the house.
