Superheat and subcooling practice test
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). WebJan 14, 2024 · What are superheat and subcooling? Superheat is defined as the amount of heat added to a vapor above its boiling point. S ubcooling is defined as the amount of heat removed from a liquid below its condensing point. Let's use water as an example to show what is going on.
