WebApr 8, 2024 · 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 ... WebJul 19, 2024 · Now you look at your digital thermometer and see the suction line temperature is 53°F. These readings would indicate you have 10°F of superheat (53-43 = 10). Calculate subcooling. Once you know superheat, you can determine subcooling to see what is happening to refrigerant on the system’s high-side.
