COF = h1-h4/h2-h1=T1(s1-s4)/T2-T1(s1-s4)=T1/T2-T1

What is the reverse of a carnot engine?

reverse carnot engine is also called a REFRIGERATION SYSTEM.


Why refrigeration cycle is called reverse carnot cycle?

The Carnot cycle is an idealized thermodynamic cycle that describes a perfect heat engine. In the Refrigeration system we need cooling effect.so it has to operate in opposite nature to produce the cooling effect. So we run the catnot cycle reversly in the refrigeration system. So we call the Refrigeration cycle called as REVERSED CARNOT CYCLE.


How do you calculate the COP of refrigeration?

See COP examples in the Cryogenics section of wikipedia SRF: http://en.wikipedia.org/wiki/Superconducting_Radio_Frequency#Cryogenics In short, COP=1/efficiency. The efficiency is the product of the Carnot efficiency and a "practical" mechanical efficiency that is typically in the range 0.25-0.3. See also wikipedia Coefficient of Performance: http://en.wikipedia.org/wiki/Coefficient_of_performance


Explain the reverse carnot cycle and from them go to ac?

Carnot Cycle is an ideal thermodynamic cycle that describes the functioning of a perfect heat engine. In the refrigeration system we need a cooling effect. So, in effect, refrigeration cycle is reverse in process than that of a carnot cycle, and ofcourse not ideal. Air-conditioners also run on the similar cycle as refrigerators.


Difference between air refregeration cycle and reversed carnot cycle?

the Carnot cycle has 2 constant specific volume processes (heat in & heat out) the air refrigeration cycle is based on a brayton cycle which has two constant pressure processes.


How do you increase the COP of a Carnot refrigerator or heat pump?

To increase the coefficient of performance (COP) of a Carnot refrigerator or heat pump, you can enhance the efficiency of the system by reducing the temperature difference between the heat source and sink, improving the insulation of the system to minimize heat losses, and utilizing more efficient components such as compressors or heat exchangers. Additionally, optimizing the working fluid and operating conditions can also help improve the overall performance of the system.


What is the reverse of heat engine operate?

The reverse of a heat engine operating is a refrigeration system operating. In a heat engine, heat is converted into work, while in a refrigeration system, work is used to transfer heat from a lower temperature to a higher temperature.

Limitations of the Carnot cycle for?

The Carnot Heat Engine Cycle and the Carnot Heat Pump Cycle are reversible cycles and do not exist in any actual operation. However, they are very useful for predicting maximum possible thermal efficiencies and coefficients of performance using the absolute temperature of the heat source and the absolute temperature of the heat sink. The Carnot Cycle consists of two reversible and adiabatic ( isentropic ) steps and two reversible and isothermal steps.
