VAPOUR COMPRESSION SYSTEM
PRINCIPLE:
In this the refrigerant is used to circulate. Refrigerant undergoes alternative phase change from liquid to vapour again vapour to liquid.
DESCRIPTION:
1.CONDENSER:
It is the place to cool the refrigerant .AIR is used for REFRIGERATOR and WINDOW AC . WATER is used as refrigerant in CENTRALISED AC.
2.RECEIVER:
It is the vessel to collect the condensed liquid refrigerant from the condenser.
3.EXPANSION VALVE(capillary tube):
Receiver is connect to the expansion valve . It will reduce the pressure of the refrigerant for reuse in the evaporator .
4.EVAPORATOR:
An evaporator consist of coiled tubes .The substance to be cooled is placed in the evaporator .It is also called freezer compartment or refrigerated space .
5.COMPRESSOR:
The evaporator tube is connect to the compressor .It is driven by electric motor .
WORKING:
LPLT --- Low pressure low temperature
HPHT ---High pressure high temperature
The refrigerant enters the evaporator at LPLT.
The LPLT vapour refrigerant is pass to suction side of compressor .Then the refrigerant is pass to condenser through delivery side at HPHT .
In condenser the latent heat of the refrigerant is removed by circulating either atmospheric air or water .The HPHT refrigerant is condensed and received in receiver .
The High pressure (HP) Liquid refrigerant pass through to expansion valve to reduce the pressure .The low pressure refrigerant pass to evaporator .
USES:
It is used in Refrigerator ,window AC , Centralized AC , ect .
If it is use to you ,I am become happy.😊
