What is the reverse Carnot principle?
Thread Content
I would like to ask the teachers for information on the reverse Carnot principle; it would be great if there were pictures available, thank you
The Carnot cycle consists of four process steps: two adiabatic processes and two isothermal processes. It was proposed in 1824 by N.L.S. Carnot (see Carnot father and son) while conducting theoretical research on the issue of the maximum possible efficiency of heat engines. Carnot assumes that the working fluid exchanges heat only with two isothermal heat sources, with no losses such as heat dissipation, air leakage, or friction. To make the process quasi-static, the heat absorption by the working fluid from the high-temperature heat source should be an isothermal expansion process without a temperature difference; similarly, the heat release to the low-temperature heat source should be an isothermal compression process. Since the restriction is to exchange heat only with two heat sources, once separated from them, it can only be an adiabatic process. A heat engine that operates in a Carnot cycle is called a Carnot heat engine. From Baidu
