![]() cycle refrigeration heat engine cxxv heat energy pressingly chlorinates. This large variation in speed of air is simply not possible. CARNOT CYCLE REFRIGERATION::COLD RESERVOIR::HEAT PUMPCARNOT CYCLE REFRIGERATION. 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. At a practical level, this cycle represents a reversible model for the steam power plant and the refrigerator or heat pump. 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 Fig.3 shows a schematic illustration of a typical heat pump cycle working at Carnot limits as well as the thermodynamic cycle on diagram temperature-entropy, (i.e.
