4.What is Sub
cooling????

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 ??????????????????
