Add refrigerant if the measured subcooling is 3 °F or more below the recommendation, otherwise withdraw refrigerant. Operation of the calculator is simple, simply select your refrigerant, enter the pressure readings from your manifold gauges, and clamp the thermocouple on the tube to activate the display reading. Before you get to crazy adding or removing gas. 7 at sea level. Subtract this temperature from the suction line temperature measured by a digital thermometer. You'll need a set of gages for 410a (has the T/P chart on the gauge scale) and a pipe clamp style digital thermometer 118 PSIG Suction line converts to 39. Superheat is the difference between the actual temperature of the refrigerant (gas) as it leaves the evaporator and the boiling point temperature of the refrigerant in the evaporator coil. If you get zero degrees Superheat with a TXV, then the TXV is defective and will need to be replaced. 7 184. On newer systems, which use electronic expansion valves and solid state controllers, it is possible to see the superheat set-ting as low as 5 °F to 10 °F. –37. 5 67.
