Aheat 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 64000 kj/h. the refrigerant enters the compressor at 240 kpa and 0°c and leaves at 1.4 mpa and 80°c. the refrigerant exits the condenser at 34°c.
a.)determine the power input to the heat pump. kw
b.)determine the rate of heat absorption from the water. kw
c.)determine the increase in electric power input if an electric resistance heater is used instead of a heat pump. kw
