The Subcool range on TXV systems will range from about 8 to 20. Checking Refrigerant Charge for R-410a …

WebMost technicians in the HVAC field know the normal range of operation for the low-pressure side of an air conditioning system. This tends to be around 60 PSI to 85 PSI for R-22 and 105 PSI to 143 PSI for R-410A and is dependent upon operating conditions. On the high-pressure side of the system, there is a wide variation in pressure due to the wide outdoor … WebThe superheat in the system with R22 is calculated by the following equation. Total Superheat with R22 = Corresponding temperature at suction pressure – Temperature measured at a suction line or outlet of the evaporator. The superheat is nearby 10 ° F in most cases. If the superheat is high, then it causes an increase in the heat of compression.
