2. 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

3. 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.

4. Any Doubt ??????????????????
