WebSep 23, 2013 · The liquid refrigerant at the pure liquid portion of the condenser would be 125°. All we have to do is use the 95° air to cool the liquid down a few degrees. The air is there, the fan is there, and there is room in the bottom of the condenser for some liquid to be cooled to below the condensing temperature. WebHow to Check Subcooling. Attach the thermometer to the liquid line. This time, near the condenser. Then take the head pressure in Psi and convert it to the temperature on the pressure/temperature chart. Assuming you are dealing with a R22 system, let’s say the head pressure is 260Psi. This will convert to 120F. geotrax new train town
