R-410A split system air conditioner. Take a pressure measurement on the liquid line where the refrigerant exits the condenser coil. ... (If the unit has a fixed orifice metering device, use the Total Superheat Charging Method.) The unit must also have proper airflow crossing the indoor coil. For every 12,000 BTU/HR of heat removal …Superheat is a way to ensure that the system is boiling off all of the liquid before it exits the evaporator. Refrigeration and air-conditioning systems may produce different superheat readings, but they are all determined the same way: by measuring indoor wet bulb and outdoor dry bulb measurements and using a pressure-temperature chart.Description. The model ASX14 superheat and subcooling accessory head measures refrigerant pressure and temperature simultaneously. It then calculates and displays superheat or subcooling.

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.
