... energy as it moves from the hot place to the cold place. This stolen energy can be used to do useful work like generating electricity or moving our car down the street. The problem is that we can only siphon off energy while heat is being transferred. Once the hot place cools off the heat flow stops ...

Heat Pumps and Refrigerators
... When a real heat engine is run backward, some of the intended work input (W ) goes into heat transfer before it gets into the heat engine, thereby reducing its coe cient of performance COPhp . In this gure, W ' represents the portion of W that goes into the heat pump, while the remainder of W is lo ...
