WebJul 10, 2024 · That is not true. It just means the liquid is cooled 10°. “For instance, if you put that condenser in a really cold ambient outside, you can have 1 inch of liquid to give you 10° of subcooling, because it’s cooling really fast,” Tomczyk continued. “But sometimes, you can have a foot backed up in the condenser with only 10° of subcooling. WebThe refrigerant is sub cooled in the condenser to avoid the early vaporization of the refrigerant before heading towards the expansion device. If proper condenser surface area is not provided to ensure proper subcooling, the refrigerant may partially evaporate in the piping as it moves to the expansion device.

WebAug 20, 2024 · SUBCOOLING – Is an amount of heat removed from the refrigerant below its condensing point. This ensures the refrigerant is in a liquid state with no gas present. … WebSubcooling or undercooling is defined as, “the process of cooling the refrigerant below condenser temperature for given pressure”. After undergoing the cooling and …
The term subcooling (also called undercooling) refers to a liquid existing at a temperature below its normal boiling point. For example, water boils at 373 K; at room temperature (293 K) liquid water is termed "subcooled". A subcooled liquid is the convenient state in which, say, refrigerants may undergo the … See more Expansion valve operation and compressor safety Subcooling is normally used so that when the refrigerant reaches the thermostatic expansion valve, all of it is in its liquid form, thus allowing the … See more In a common refrigeration system, the refrigerant undergoes phase changes from gas to liquid and from liquid back to gas. This enables to consider and discuss superheating and subcooling phenomena, mainly because gas must be cooled to become liquid and … See more The subcooling process can happen in many different ways; therefore, it is possible to distinguish between the different parts in which the process takes places.
