Of these three states, only a gas (also sometimes called vapor or steam) can be superheated. 1.Superheat and Sub-Cooling. Whenever an HVAC technician needs to add refrigerant to a system or adjust the charge the tech needs to know what superheat and/or sub-cooling is to properly ensure the refrigerant charge is correct. It is also important to have a pressure-temperature or PT Chart to properly read the pressures and temperatures. The formula to calculate both superheat and subcooling is more than easy as all you need to do is just subtract the current temperature from the boiling or condensation temperature of the water gas. If you are calculating superheat, you will need to subtract the current temperature from the boiling temperature which will be as:
