Principles of Superheat. Superheat is the temperature of the refrigerant vapor above its saturation temperature. Superheating is done by the load. If the load is low, the superheat will be low. If the load is high, the superheat will be high. Superheat is sensible heat transfer that provides very little useful cooling.The latent heat is by magnitudes higher than the sensible heat. Latent heat is the energy needed to overcome the intermolecular forces to trigger a phase change. Sensible heat is the energy needed ...Determine the amount of subcooling by subtracting the liquid line temperature from the saturation temperature of the refrigerant.
