How to do subcooling
WebAt a high level, superheat occurs when you heat vapor above its boiling point. Subcooling occurs when you cool a vapor below the temperature at which it turns into a liquid. But … WebSubcooling is when the temperature of the refrigerant liquid is below the saturation temperature. This can happen at the beginning of the refrigeration cycle, when the system is first turned on, or if there’s a problem with the system. Subcooling is the difference between the saturation temperature and the actual liquid refrigerant temperature.
