Superheat formula.

Suction superheat is a significant measurement. The point of taking that measure is a few inches from the suction service valve at the compressor. My rule of thumb for that superheat is: No less than 20 °F superheat and no more than 60 °F superheat! This is a "rule of thumb" and is only recommended as a guideline. The important Example 2: Target Superheat Calculation (This calculation will get you close to manufacturer superheat chart results) WB is 64° F, DB is 96° F. Target Superheat Formula = [(3 x WB) – 80 – DB] /2 [(3 x 64) – 80 – 96] /2 = Target Superheat. 3 x 64=192, 192-80=112, 112-96=16 16/2=8° F of Target Superheat. 8° F of Target Superheat Superheat charging is a method of adjusting the refrigerant charge in a refrigeration system to achieve a specific amount of superheat, ensuring the system operates efficiently. Superheat is the number of degrees a refrigerant vapor is above its saturation temperature at a particular pressure. This method is commonly used in systems with ...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.

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. 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. Something I learned a long time ago. I compared it to chart with random conditions. It is remarkably accurate. This formula is used to get the target superheat for a fixed orifice in cooling. Works with any refrigerant.
