May 4, 2019 - Carnot Heat engine (based on Carnot Cycle) was a concept developed by Nicolas Leonard Sadi Carnot so that one can visualize a reversible heat engine. The Carnot Cycle The Carnot cycle is the most efficient power cycle and it is composed of four totally reversible processes: Fig. 2-2: P-v and T-s diagrams for the Carnot cycle (in a cylinder-piston). Process 1-2, isothermal heat transfer (heat supply): heat is supplied at constant temperature TH
The Carnot cycle is a totally reversible cycle. The Carnot refrigeration cycle can be achieved if one reverses all the processes in the Carnot power cycle. In this case, heat in the amount of Q L is received by the gas from a heat sink and heat in the amount of Q H is rejected to a heat source, and a work input of W net,in is required to accomplish the cycle.

On a PV Diagram, the Carnot Cycle looks like a warped parallelogram. The area enclosed by the cycle path is equal to the net boundary work for the cycle. Because the state of the system moves around the cycle path in a clockwise direction, we know that the net work is positive and this cycle is a power cycle.
