A heat pump is used to meet the heating requirements of a house and maintain it at 20°C. On a day when the outdoor air temperature drops to 22°C, the house is estimated to lose heat at a rate of 80,000 kJ/h. If the heat pump under these conditions has a COP of 2.5, determine (a) the power consumed by the heat pump and (b) the rate at which heat is absorbed from the cold outdoor air.

A heat pump is used to meet the heating requirements of a house and maintain
it at 20°C. On a day when the outdoor air temperature drops to 22°C,
the house is estimated to lose heat at a rate of 80,000 kJ/h. If the heat
pump under these conditions has a COP of 2.5, determine (a) the power
consumed by the heat pump and (b) the rate at which heat is absorbed from
the cold outdoor air.
