Subcooling is a measurement of temperature DECREASE of a liquid below its saturation (mixed liquid/vapor) temperature at a given pressure. For example, water boils at 212° Fahrenheit at sea level (atmospheric pressure of 14.7 PSIA). If water is 212°F and at atmospheric pressure at sea level, you can be sure it is at saturation, which means it ...
Superheat is a way to ensure that the system is boiling off all of the liquid before it exits the evaporator. Refrigeration and air-conditioning systems may produce different superheat readings, but they are all determined the same way: by measuring indoor wet bulb and outdoor dry bulb measurements and using a pressure-temperature chart.If the system's pressure is 250 PSI, using the Superheat Calculator 410A, we can calculate the superheat as follows: See also Raychem Heat Trace Calculator Online. Superheat = 45°F - 65°F = -20°F. Therefore, the superheat value in this scenario would be -20°F (-28.89°C).This video will show you how and where to measure the temperature on a R-410A Split System for calculating superheat and sub cooling measurements. You can ap...Note: When charging a system using superheat, you are basically charging the unit to the amount of air that is crossing the evaporator. Note: Do not adjust charge based on superheat on systems with thermal expansion valves (TXV’s). TXV’s control the superheat. You can, however, check the superheat to see if the TXV is working properly.
