Q7: An air conditioning system is used to maintain a house at a constant temperature of 20 C. The house is gaining heat from outdoors at a rate of 21000 kJ/h, and the heat generated in the house from the people, lights, and appliances amounts to 9000 kJ/h. For a COP of 2.4, determine the required power input to this air conditioning system.
