Evaporator Superheat Method: 1. Take the suction line pressure and temperature at the condenser's suction service valve (air conditioning) or service port at the compressor (heat pump). If you use a probe-type thermometer, put a piece of pipe insulation around the probe and pipe. 2.When vapor changes to liquid, some heat is removed at the saturated condensation temperature. Further reduction in temperature is subcooling. When liquid changes to vapor, extra heat is introduced in liquid. Upon reaching the boiling point of the refrigerant, a further increase in temperature is superheat. To understand large industrial cooling systems, …Subcooling (R-134A) = 88°F – 82°F = 6°F.
