how do you calculate superheat and subcooling

6+ Easy Ways: Calculate Superheat & Subcooling, Fast!

Superheat is the temperature improve of a vapor above its saturation temperature at a given strain. It’s decided by subtracting the saturation temperature from the precise refrigerant vapor temperature at a selected level within the system, usually on the evaporator outlet. The end result signifies the variety of levels the vapor is above the purpose at which it will start to condense. For instance, if the measured refrigerant temperature is 55F and the saturation temperature is 40F, then the superheat is 15F.

Subcooling, conversely, is the temperature lower of a liquid under its saturation temperature at a given strain. It’s discovered by subtracting the measured liquid refrigerant temperature from the saturation temperature at a selected level, mostly on the condenser outlet. This worth illustrates the diploma to which the liquid is cooler than the purpose at which it will start to boil. Larger subcooling usually signifies improved system effectivity. Making certain enough subcooling is essential as a result of it prevents flash fuel from coming into the metering system, which might cut back cooling capability.
