Question

A reversible heat engine operates between two reservoirs at temperatures of 600c and 40c. The engine drives a reversible refrigerator which operates between reservoirs at temperatures of 40c and 20c. The heat transfer to the heat engine is 2000 kj and the net work output for the combined engine refrigerator is 360 kj. (i) calculate the heat transfer to the refrigerant and the net heat transfer to the reservoir at 40c. (ii) reconsider (i) given that the efficiency of the heat engine and the
c.O.P. Of the refrigerator are each 40 per cent of their maximum possible values.
