A heat pump using refrigerant-134a heats a houseby using underground water at 8°C as the heat source. Thehouse is losing heat at a rate of 60,000 kJ/h. The refrigerantenters the compressor at 280 kPa and 0°C, and it leavesat 1 MPa and 60°C. The refrigerant exits the condenserat 30°C. Determine (a) the power input to the heat pump,(b) the rate of heat absorption from the water, and (c) theincrease in electric power input if an electric resistanceheater is used instead of a heat pump.

Question
A heat pump using refrigerant-134a heats a house
by using underground water at 8°C as the heat source. The
house is losing heat at a rate of 60,000 kJ/h. The refrigerant
enters the compressor at 280 kPa and 0°C, and it leaves
at 1 MPa and 60°C. The refrigerant exits the condenser
at 30°C. Determine (a) the power input to the heat pump,
(b) the rate of heat absorption from the water, and (c) the
increase in electric power input if an electric resistance
heater is used instead of a heat pump.
