Compression of hot gas 2. Cooling 3. Condensing 4. Subcooling 5. Expansion 6. Evaporation 7. Super heating A basic vapor compression refrigeration systemCalculate. This free online tool allows HVAC professionals to quickly calculate Superheat and Subcooling measurements for both R22 & R410A refrigerants.1. a) Most walk-in coolers and freezers use a TX valve to regulate the flow of refrigerant into the evaporator. If the superheat is low the TX valve will allow refrigerant to flow into the evaporator at a rate that exceeds the capacity of the evaporator and as a result liquid will enter the suction line.If superheat is generated in the suction pipe, then the heat is absorbed from the medium in which the pipe is located (for example ambient air). ... Subcooling is another method to improve the efficiency of the refrigeration cycle.

Superheat and subcooling serve different purposes in HVAC systems. While superheat focuses on the evaporator side, ensuring that all liquid refrigerant boils off before reaching the compressor, subcooling deals with the condenser side, making sure that refrigerant loses enough heat after condensation.

Unfortunately, there is a lot of misunderstanding as to what exactly Superheat and Subcool actually are and even less understanding on how to measure it. There are so many novice technicians that get ‘stumped’ on a system without even checking Subcool or Superheat temperatures…. or if they did check them they checked in the wrong section.
