The subcooling of a liquid, particularly in the context of refrigeration cycles, is calculated by the formula: ( Subcooling value = Temperature of saturated liquid – Temperature of liquid line) Where: is the temperature of the saturated liquid at a given pressure, measured in degrees Fahrenheit (°F) or Celsius (°C).

Superheated vapor or superheated steam is a vapor at a temperature higher than its boiling point at the absolute pressure where the temperature is measured. The pressure and temperature of superheated vapor are independent properties, since the temperature may increase while the pressure remains constant. Actually, the …

The total superheat method is used to measure the increase in temperature of the vapor refrigerant at the evaporator plus any additional temperature change that occurs while the vapor refrigerant travels to the outdoor unit. Below is a picture of refrigerant superheating from 40 °F to 54°F inside an evaporator coil.Calculate superheat: Subtract the saturation temperature from the suction line temperature (Suction Line Temperature – Saturation Temperature = Superheat). Example: If you have a suction line temperature of 65°F (18.3°C) and saturation temperature at 45°F (7.2°C), the superheat calculation will be as follows: 65°F – 45°F = 20°F superheat.superheat: [verb] to heat (a vapor not in contact with its own liquid) so as to cause to remain free from suspended liquid droplets.The best answer is—as usual—whatever the manufacturer says it should be.
