WebJun 3, 2004 · The superheat changed from 7 degrees to 15 degrees simply by reading the pressure at the compressor inlet instead of the evaporator outlet. This correct evaporator superheat would be 7 degrees. It is best to measure the pressure at the same location as you measured the temperature to exclude any system pressure drops. WebThis temperature rise above the saturation temperature (boiling point) for that constant pressure is called superheat. Superheat in Action Actual superheat is calculated from your suction line pressure and temperature measurements. The formula is: suction line temperature – suction line saturation (boiling) temperature = actual superheat
