The temperature of the suction line at the. This is 4 hvac scenarios on how to measure subcooling or superheat to check a refrigerant charge level.
While superheat indicates how much refrigerant is in the evaporator (high superheat indicates not enough, low superheat indicates too much), subcooling gives an indication of how much refrigerant is in the condenser. The sum of the sensible and latent heat of the air is called enthalpy or total heat. Subcooling is beneficial because it prevents the liquid refrigerant from changing to a gas before it gets to the evaporator. Recalling that latent heat is the heat which is added to a liquid to cause it to change from a liquid to a.
