If the R410A units low pressure was 110 psi (755 kPa) and the suction pipe temperature was 12ºC then: 110 psi (755 kPa) converted to temperature is 2ºC, so we then subtract 2 from the 12º pipe temperature which results in a superheat of 10ºC; indicating in this case it’s a little high and requires lowering.

In order to correct this R-22 was phased out across the world. Here in America our phase out began in 2010 and the refrigerant will be completely phased out in 2020. Taking R-22’s place is the HFC refrigerant blend known as R-410A, our Puron. As I write this article, in 2019, there are still thousands of R-22 machines out there, but they are ...
