Using an engine of 30% thermal efficiency to drive a refrigerator having a COP of 5, what is the heat input into the engine for each MJ removed from the cold body by the refrigerator? If this system is used as heat pump, how many MJ of heat would be available for heating for each MJ of heat input to the engine.
