What is vapour compression cycle.

Question

Accepted Answer

Vapour compression cycle is a thermodynamic process used in refrigeration and air conditioning systems.

It involves the compression of a refrigerant gas to a high pressure and temperature, followed by condensation into a liquid at a lower temperature.
The liquid refrigerant then passes through an expansion valve, where it undergoes a pressure drop and evaporates at a low temperature and pressure.
The evaporated refrigerant absorbs heat from the surroundings, cooling the space or object being refrigerated.
The cycle is completed when the refrigerant is compressed again to start the process over.
Common examples of vapour compression cycle systems include refrigerators, air conditioners, and heat pumps.
