The following steps outline how to calculate the Superheat. First, determine the compressor temperature (F). Next, determine the saturation temperature (F). Next, gather the formula from above = SH = C T – ST. Finally, calculate the Superheat.

Superheat measurement is fundamental in thermodynamics and has been used since the development of refrigeration and air conditioning systems. It helps in determining the efficiency and safety of these systems. Calculation Formula. The superheat (SH) is calculated using the formula: \[ SH = CT - ST \] where: To calculate superheat, we must have the steam pressure (P, bars) and temperature (T, ºC). Superheat is the difference between steam temperature, T, and saturation temperature, Tsat, at pressure, P. (To use English units, you will have to convert to metric to run the routine, then convert back to English when you get the answer). The method is ... Subcooling formula. The subcooling of a liquid, particularly in the context of refrigeration cycles, is calculated by the formula: ( Subcooling value = Temperature of saturated liquid – Temperature of liquid line) Where: is the temperature of the saturated liquid at a given pressure, measured in degrees Fahrenheit (°F) or Celsius (°C).High superheat is an AC problem that won’t go away by itself (except due to the #4 cause). We have to fix high superheat. In order to do that, it’s particularly useful to understand what causes high superheat in air conditioners. There are 6 common high superheat culprits that we always check, and we’ll go over all of them one-by-one.To measure liquid subcooling: 1. Attach your gauge manifold to the liquid line service port. If you use a quick-connect fitting on the end of your hose, make sure it’s a low-loss fitting. I’ve seen some quick-connect fittings that allow pressure loss, which can cause inaccuracies in the charging procedure.The formula to calculate both superheat and subcooling is more than easy as all you need to do is just subtract the current temperature from the boiling or condensation temperature of the water gas. If you are calculating superheat, you will need to subtract the current temperature from the boiling temperature which will be as:The excess energy = 2 741.7 - 2 706.7 = 35 kJ/kg, and this is used to raise the temperature of the steam from the saturation temperature of 120 °C to 136 °C. The degree of superheat can be determined either by using superheated steam tables, or by using a Mollier chart.Too much refrigerant in the evaporator coil. This is the case in the #4 and #5 causes in the list below. Not enough indoor heat to adequately vaporize the refrigerant.
