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.Subcooling is a measurement of temperature DECREASE of a liquid below its saturation (mixed liquid/vapor) temperature at a given pressure. For example, water boils at 212° Fahrenheit at sea level (atmospheric pressure of 14.7 PSIA). If water is 212°F and at atmospheric pressure at sea level, you can be sure it is at saturation, which means it ...

Note: When charging a system using superheat, you are basically charging the unit to the amount of air that is crossing the evaporator. Note: Do not adjust charge based on superheat on systems with thermal expansion valves (TXV’s). TXV’s control the superheat. You can, however, check the superheat to see if the TXV is working properly.Below is an example of an R-410A split system air conditioner.

Note: When charging a system using superheat, you are basically charging the unit to the amount of air that is crossing the evaporator. Note: Do not adjust charge based on superheat on systems with thermal expansion valves (TXV’s). TXV’s control the superheat. You can, however, check the superheat to see if the TXV is working properly.Shut off the air conditioner. We need an equalized system before we start measuring …An essential tool for charging 410A by subcooling is a set of HVAC gauges. These gauges allow you to measure the pressure in your system, helping you determine the correct refrigerant charge. Make sure to use gauges specifically designed for …The low side pressure of a typical R410A mini split is between 110-140 psi depending on the operating conditions. Though it can vary, the low side pressure of a mini split should not fall below 100 psi or raise beyond 160 psi. The working pressure of mini splits is depending on factors such as the weather and cooling load.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.
