Refrigeration Cycle

Refrigeration cycle is a cycle of mechanical system in which transmission of heat flow from one place at a lower temperature to another place at a higher temperature.

What is 


Refrigeration means cooling a space, substance or system to lower and/or maintain its temperature below the ambient one

Refrigeration Cycle 


Refrigeration cycle is a thermodynamic cycle to generate refrigerating effect with the use of evaporator, compressor, condenser & expansion valve.

Vapour Compression


It uses the physics of phase change heat transfer and the  properties of a refrigerant to transfer heat from a relatively cold source to a hot medium.

Components of 

Refrigeration Cycle

The 4 main Components of Refrigeration cycle 1. Compressor 2. Condenser 3. Expansion valve 4. Evaporator


The compressor in a vapor compression cycle helps in raising the pressure of the vaporizer refrigerant, causing its saturation temperature to rise



The temperature at which a fluid boils or condenses is known as the saturation temperature .


In the condenser of the vapour compression system the refrigerant is liquefied by being subcooled to below the saturation temperature relating to the compressor delivery pressure
