The Carnot cycle is a reversible cycle so the four processes that comprise it, two isothermal and two isentropic, can also be reversed. This is due to the fact that the isentropic process requires high speed and the isothermal process requires extremely low speed.

Carnot cycle and its efficiency” and we have also seen the concept of “Carnot theorem and its explanation” in our previous post.
Reversed Carnot cycle. TECHNICAL CLASSES 47,415 views. REVERSE CARNOT CYCLE- AIR REFRIGERTATION SYSTEM - Duration: 10:24. Fig. In the reverse Carnot cycle, work is done to extract heat from one system and expel it into another via four processes, two isothermal and two isentropic.

The Carnot heat-engine cycle described is a totally reversible cycle. Reverse Carnot cycle is most efficient between the fixed temperature limits yet no refrigerator could be made using this cycle.

Sadi Carnot is referred to as the founder of thermodynamics for discovering the heat and work relationship. Reversed Carnot cycle is the same as that of conventional Carnot Cycle except for the direction of the processes.

Let us take an example related to it.

The reversed Carnot cycle also consists of two isentropic and two isothermal processes.

3.4.1 Reversed Carnot Cycle. Carnot was one of the first to realize that heat is essentially work in a different form. Numerical on Bell coleman cycle or reverse joule cycle - Duration: 6:07. Reversed Carnot cycle. Today we are interested to see the basic and fundamental concept of reversed Carnot heat engine cycle or reversed Carnot cycle with the help of this post.

If the Carnot cycle shown in Fig. 3.18, then the directions of the work and heat transfer terms are also reversed. That is all the processes that compose it can be reversed, in which case it becomes the Carnot refrigeration cycle. Numerical on Bell coleman cycle or reverse joule cycle - Duration: 6:07. A refrigerator or heat pump that acts on the reversed Carnot cycle is called a Carnot refrigerator or Carnot heat pump respectively.

3.1 is operated in reverse, i.e.


10:24. Reversed carnot cycle consists of four processes in which two processes are ishothermal process and two are isentropic process undergoes in direction 3-2-1-4-3. It gives the estimate of the maximum possible efficiency that a heat engine during the conversion process of heat into work and conversely, working between two reservoirs, can possess. A refrigerator or heat pump that operates on the reversed Carnot cycle is called a Carnot refrigerator or a Carnot heat pump. On this basis, various refrigeration cycles are being compared. the arrows on the diagram are turned round, as in Fig. 5-1: T-s diagram and major components for Carnot refrigerator. The process undergoes in direction 3-2-1-4-3 Process 3-2: Reversible Adiabatic Compression This process is …
