Total superheat includes evaporator superheat plus additional heat picked up in the suction line between the evaporator and compressor. It’s the type most commonly measured in the field. Many compressor manufacturers recommend a total superheat of 10° to 15°F to assure the compressor doesn’t overheat or suffer from floodback.Actual Line Temp – Sat Temp = Total Superheat. 55°F - 37°F = 18°F. 18°F of Total Superheat > 9°F Target Superheat = Undercharged. Since the actual total superheat measured is higher than the target superheat, we would need to add refrigerant a little at a time until the superheat is the same as the target superheat.

But why do we care? We measure superheat (generally) on the suction line exiting the evaporator coil, and it helps us understand a few things. #1 – It helps ensure we are not flooding the compressor. 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.heating check charts index model hertz diagram (on unit) fig. no. 38ay024 38ay030 38ay036 38ay042 38ay048 38ay060 38aym024 38aym030 38aym036 38aym042 38aym048 38by024 38by030 38by036 38by042 38by048 38by060 60 320347-101 1 38yc018 38yc024 38yc030 38yc036 38yc042 38yc048 38yc060 38ycm024 38ycm030 38ycm036 …
