A heat pump supplies 40 kw of heat to maintain the inside, Ask an Expert

Engineering

A heat pump supplies 40 kW of heat to maintain the inside of a house at 25 degree C in cold winter months when the ambient temperature is 0⁰C. Power required to operate the heat pump cycle is provided by a heat engine cycle which receives 10 kW of heat from a reservoir at 50⁰ degree C. The heat engine has thermal efficiency of 50%. The heat engine rejects heat to the ambient reservoir at 0⁰C.

a) Calculate the coefficient of performance of the heat pump.

b) Determine the net rate of heat transfer (kW) for the ambient reservoir.
