![]() ![]() In this process, the air is compressed with a constant temperature while losing heat. That is no change in entropy, and the system is insulated ![]() In this process, the air is expanded, keeping entropy constant and with no heat interaction. Process 2-3: Reversible adiabatic expansion That is, constant temperature heat addition takes place.Įxpansion => pressure ↑ => results Temperature ↓ In this process, the air is expanded with constant temperature while gaining heat. Heat addition and Heat rejection are carried out at a constant temperature, but no phase change is considered. The working medium used in the Sadi-Carnot cycle is atmospheric air. It consists of four reversible processes, of which two are isothermal, i.e., constant temperature followed alternately by two reversible adiabatic processes.

Carnot’s contribution holds a remark which gave him the title of “Father of Thermodynamics. It leads to being the foundation of the Second law of thermodynamics and entropy. This large variation in speed of air is simply not possible.Nicolas Léonard Sadi-Carnot, a French mechanical engineer, Scientist, and physicist, introduced a heat engine known as the Carnot Engine in the book “Reflections on the Motive Power of Fire. This is because that the isentropic process of Carnot cycle requires a high speed of air while the isothermal process of Carnot cycle requires extremely slower speed. Even though no heat engine and refrigerator used Carnot cycle. Similarly, a refrigerator working on reversed Carnot cycle give the highest possible coefficient of performance. As we know that, between the fixed temperature limits, a heat engine operating on Carnot cycle give highest possible efficiency. In working of refrigerator, the term Carnot cycle represents the reversed Carnot cycle. Read: COP of air refrigerator working on reversed carnot cycle with PV and Ts diagram ![]()
