PROBLEM 4 A heat pump is used to meet the heating requirements of a house and maintain it at comfortable temperature. On an average winter day, the house is estimated to lose heat at rate of 80,000 kJ h¯¨¹. The heat pump has a COP of 2.5 under these conditions. Questions: (a) Determine the net power input required by the heat pump, in kW. (b) The rate at which heat is extracted from the cold outdoor air, in kW.
