Subheating and subcooling
WebSubcooling on systems that use a thermostatic expansion valve (TXV) should be approximately 10F to 18F. What is the proper superheat and subcooling? “Typically” on TXV systems the Superheat will range between 8 to 28 degrees with a target of about 10 to 15 degrees. The Subcool range on TXV systems will range from about 8 to 20.
