You can find your target... Determine the amount of subcooling by subtracting the liquid line temperature from the saturation temperature of the refrigerant. According to industry standards, superheat should be 12-15 degrees in ambient air temperature below 85°F and 8-12 degrees in warmer air. Subcooling should be 5-18 degrees, with higher values when the equipment has a ...Actual Line Temp – Sat Temp = Total Superheat. 55°F - 37°F = 18°F. 18°F of Total Superheat > 9°F Target Superheat = Undercharged. Since the actual total superheat measured is higher than the target superheat, we would need to add refrigerant a little at a time until the superheat is the same as the target superheat.

Superheated vapor is solvent vapor heated to and beyond its normal boiling point at atmospheric pressure. Its unique capability is to heat materials to above the normal boiling point of the solvent used. The prime use of superheated vapor is to vaporize the last traces of liquid solvent retained within part crevices.

(°F) If the measured vapor line temperature does not agree with the required vapor line. 7 temperature, add refrigerant to lower ...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 ...

Matt, how can I determine what the target superheat formula is if I don't have the manufacturer's charging chart? That's a great question and it's a really simple formula that you can use in the field and it can help you get out of that bind if you don't have the OEM data to figure out where the charge needs to be and the formula for that is is going to be three times the indoor wet bolt ...The SI equivalent of this formula would be: TSH=IWB- (OAT-IWB)/2-4.44.

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. That means understanding and measuring all three types of superheat: evaporator, total, and duct system. 1. Evaporator superheat. To measure evaporator (indoor coil) superheat, first measure the suction line temperature at the evaporator outlet. Next, measure the refrigerant pressure at the suction line of the indoor coil.
