i know that superheat is heat added to a vapor if you were checking dis. s.h. would you take dis. pressure convert to temp on chart and then read actual temp of dis. line?

yes you got it. same way as suction superheat

thanks for the reply.what are the parameters of normal discharge superheat and the causes of high and low temps

depends on what type of compressor. for an example a trane rtha will run low 20's at full load. carrier gx will go for 22 degrees at any load. on recips i like the discharge temp not to be any higher than 200 degrees when fully loaded. always check the manufactor specs on the machine.

I think for R-22 A/C a discharge superheat between 50 and 90 DEGF is normal. If it's lower than that, you're probably flooding back. If higher then low on charge, or restriction, etc.
