What is Vapour compression refrigeration system?
- Vapour compression refrigeration system is one of the type of refrigeration system, Extensively used in refrigeration, Air conditioning for Industrial, Domestic, and Automobile uses.
- This system uses the compressor to compressed the refrigerant.
- The Refrigerants uses in VCR are NH3, R-134a, R-12, R-22 etc.

Construction:
The key components of a vapour compression refrigeration system are Expansion Valve, Compressor, Condenser, Evaporator.
COMPRESSOR:- Is Used to Compressed the Refrigerant to High Pressure.
EVAPORATOR:- is Used to Absorb Heat From The Enclosed Space with the Help of Refrigerants.
CONDENSER:- is Used to Exchange Heat of Refrigerant with Cooling Medium may be air or Water.
CONDENSER:- is Used to Exchange Heat of Refrigerant with Cooling Medium may be air or Water.
EXPANSION:- Valve Used in System to Convert High Pressure, High-Temperature Refrigerant to Low Pressure, Low Temperature.
Working of vapour compression refrigeration system:
1] When the Refrigerant Come Inside the Compressor, Compressor Compress the Refrigerant And Increases Pressure & Temperature. At Exit of the Compressor Refrigerant Is in the form of Vapour State.
2] After Coming From Compressor, Hot Vapour Refrigerant Enters into the Condenser. In Condenser, Refrigerant gets Cooled by a Cooling Medium. Hence Vapour Refrigerant Converted into Liquid State.
3] After Condenser, Liquid Refrigerant Enters into the Expansion Valve. By Expanding the Refrigerant, Expansion Valve Reduce the Pressure, Temperature of Refrigerant. Due to Expansion Liquid Refrigerant Converted into Vapour State.
4] After the Expansion Valve, Vapour Refrigerant Enters into the Evaporator. In Evaporator, Refrigerant absorbs the Heat From Enclosed space & gets Heated.
After Evaporator, Refrigerant Again Enters into Compressor.
