Jul 8, 2022 · Take the suction pressure and use the pressure/temperature chart to convert it to temperature. Let’s say the suction pressure is 60(Psi) which converts to 34F. And assuming that the suction line temperature is 44F. Then to get superheat we just get the difference between the two temperature readings. In this case, we have 10F of superheat. Heating mode: outside temp >65F: Run AUX only - lock out compressor (avoid high pressure) outside temp >10F and <65F: Run compressor and AUX as needed. outside temp <10F: Run AUX only - lock out compressor (avoid defrost cycling) Cooling mode: outside temp <60F: lock out compressor, run air handler fan only.

A bad check valve on an air conditioner, heat pump or similar HVACR equipment can show up as abnormally low or abnormally high suction line pressures, or as abnormally low or high superheat. Experts suggest using an IR heat gun or similar tempeature measuring tool to check the tempeature of the refrigerant line on each side of the valve. After the suction line has been strapped to the joist or rafter at 8’ (2.4 m) intervals, strap the liquid line to the suction line. 8’ (2.4 m) Metal Sleeve Wire Tie (around suction line only) Floor Joist or Roof Rafter Tape or Wire Tie Tape or Wire Tie If hanging line set from a joist or rafter, use metal strapping or heavy nylon wire tires Let’s use the target superheat formula and calculate this manually: Target Superheat (R-410A) = (3 × 69°F – 80°F – 105°F) / 2 = 11.0°F. We see that the target superheat for R-410A refrigerant in this system is 11°F.
