Web1 mrt. 2011 · The most popular form of measuring subcooling that i have see in terms of consistancy is discharge pressure at discharge service valve, convert to a temperature, take a temprature reading at the liquid line close to the expansion valve, subtract the two, and the resulting difference is subcooling. WebSub cooling = saturated condensing temperature – liquid temperature The liquid temperature is measured 100 mm from the inlet to the expansion valve Sub cooled does not mean cold: a hot cup of coffee from a vending machine at 85OC is a sub cooled liquid Obecause it is 15 C cooler than the saturation temperature of the water (1000C). WebSubtract the Liquid line Temperature from the Liquid Saturation Temperature and you get a Subcooling of 15. “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. highclere horse
