WebbA. In reality, there is no 100% efficient engine because the change in internal energy of a system equals the difference between the heat taken in by the system and the work done by the system B. In reality, there is no 100% efficient engine because there is only heat transfer from hot to colder objects C. Webb23 aug. 2024 · The "efficiency" for heat pumps and chillers is called coefficient of performance (COP), because there is no conversion of electrical energy to heat energy but only a transportation. This COP can be way higher than 1, a heat pump can supply more heat energy than you put electrical energy into it.
