We use gauges and a temperature probe to measure subcooling, just like when measuring superheat. 2. We check the temperature of the liquid line near the condenser coil. 3. We’ll check the head pressure at the condenser, comparing the readings to the manufacturer’s standard. 4. Then we subtract the two numbers to calculate subcooling. High subcooling shows that the condensing point is occuring earlier in the condenser while low subcooling shows that the condensing point is later in the condenser. Subcooling is used to charge systems with a TXV. Now you can see why knowing what, and why, superheat and subcooling are essential to proper diagnostics and …8. If the actual superheat is greater than the recommended superheat obtained from the table by more than 5°F, add 2-4 ounces of refrigerant, and wait at least ten minutes before repeating this superheat procedure. 9.

You can still check the subcool and superheat in heat mode; the problem is that since there are rarely any set guidelines, it is difficult to tell when the charge is set correctly by simply checking the subcool or superheat alone. Generally, you will see normal superheat (8°-14°) on a system with heat mode TXV, and the subcooling will ...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 ...:gah:Just had system serviced but system does not seem to be cooling. Checked temp diff from supply to return and was 10 degrees. So checked pressures at condenser. What does a normal superheat (10 degree) with a low subcool temp (zero degrees) mean? It is a nice day out and outdoors is only at 82. Cant imagine service …Subcooling is beneficial because it prevents the liquid refrigerant from changing to a gas before it gets to the evaporator. Pressure drops in the liquid piping and vertical risers can reduce the refrigerant …
