Subcooling

Subcooling is the amount of heat removed from a refrigerant after it has condensed into a liquid. Liquid refrigerant is subcooled at constant pressure before entering the expansion valve, which increases both the refrigeration effect and the coefficient of performance (COP) of the refrigeration system. The degree of subcooling is measured as the saturation temperature of the refrigerant minus the temperature of the refrigerant leaving the condenser.

By Er.Ashutosh 4.What is Sub cooling????
• It is amount of heat removed from a refrigerant after it has already condensed to liquid. • Liquid refrigerant is sub cooled at constant pressure before entering to expansion valve. Sub Cooling
Degree of Sub cool =Saturation Temperature of refrigerant(T3)-Temp. of refrigerant out from condenser(T3’) Condenser outlet temperature must be measure from thermistor or thermocouple Effect Of Sub Cool 1.Refrigeration effect increased. 2.COP Increased.
Any Doubt ??????????????????
