What is refrigeration and vapour absorb ration system compression,condensation expansion evaporation.

Question

Accepted Answer

Refrigeration is a process of cooling a space or substance below the ambient temperature using a refrigerant and a compression cycle.

Refrigeration is used in various applications such as air conditioning, food preservation, and industrial processes.
The refrigeration cycle involves compression, condensation, expansion, and evaporation of a refrigerant.
Compression: The refrigerant is compressed to increase its pressure and temperature.
Condensation: The high-pressure refrigerant releases heat and condenses into a liquid state.
Expansion: The liquid refrigerant passes through an expansion valve, reducing its pressure and temperature.
Evaporation: The low-pressure refrigerant absorbs heat from the surroundings, evaporating into a gas state.
Vapour absorption refrigeration is an alternative to compression refrigeration, where a refrigerant is absorbed into a liquid and then released through heat input.
Vapour absorption refrigeration systems are commonly used in large-scale applications and where waste heat is available.
