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 … 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 valve to work properly. If gas reaches the expansion valve a series of unwanted phenomena may occur. These may end … Ver más 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". … Ver más In a common refrigeration system, the refrigerant undergoes phase changes from gas to liquid and from liquid back to gas.
