RA heat pump that operates on the ideal vapor-compression cycle with refrigerant-134a is used to heat a house and maintain it at 75°F by using underground water at 50°F as the heat source. The house is losing heat at a rate of 82000 Btu/h. The evaporator and condenser pressures are 60 and 180 psia, respectively. Determine the power input to the heat pump and the electric power saved by using a heat pump instead of a resistance heater.
