WebQ c Q h = T c T h. Finally, with Equation 4.2, we find that the efficiency of this ideal gas Carnot engine is given by. e= 1– T c T h. (4.5) (4.5) e = 1 – T c T h. An engine does not necessarily have to follow a Carnot engine cycle. All engines, however, have the same net effect, namely the absorption of heat from a hot reservoir, the ... WebJun 13, 2024 · The COP is defined as the ratio of the desired heat transfer to the work required to make the transfer. What is considered to be the "desired heat transfer" depends on whether you are looking at it as a heat pump or as an air conditioner/refrigerator. C O P H P = Q H W C O P A C = Q L W and since W = Q H − Q L C O P H P = Q H Q H − Q L
