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.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.

Superheat and Sub-Cooling. Whenever an HVAC technician needs to add refrigerant to a system or adjust the charge the tech needs to know what superheat and/or sub-cooling is to properly ensure the refrigerant charge is correct. It is also important to have a pressure-temperature or PT Chart to properly read the pressures and temperatures. Embark on a journey through a step-by-step gui 3. Calculate superheat: Subtract the saturation temperature from the suction line temperature (Suction Line Temperature – Saturation Temperature = Superheat). Example: If you have a suction line temperature of 65°F (18.3°C) and saturation temperature at 45°F (7.2°C), the superheat calculation will be as follows: 65°F – 45°F = 20°F ... AC SERVICE TECH, LLC.

For this example the Liquid line Temp is 95 degrees. Subtract the Liquid line Temperature from the Liquid Saturation Temperature and you get a Subcooling of 15. “Typically” on TXV systems the Superheat will range between 8 to 28 degrees with a target of about 10 to 15 degrees. The Subcool range on TXV systems will range from about 8 to 20. h sup = 10 + 2 x (-2) h sup = 10 + (-4) h sup = 6. Therefore, the enthalpy of superheated steam is 6 J/Kg.

Example 2: Target Superheat Calculation (ThiQuickly calculate Superheat, and Subcooling Delta T = 77°F – 56°F = 21°F. We can see that delt 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 clamp-on thermometer reads 77°F. Here is how we use the subcooling formula to manually calculate the subcooling in this system: Subcooling (R-22) = 89°F – 77°F = 12°F. We see that the calculated subcooling for R-22 refrigerant in this system is 12°F. This is the manual calculation. TLV ToolBox - For iOS and Android.
