Glory Tips About How To Check Subcooling

To check subcooling, attach a thermometer to the liquid line near the condenser.

How to check subcooling. In this hvac refrigerant charging video i explain how to check and measure the superheat and subcooling charging processes for r22 and r410a freon. On the condenser, take a pressure reading at the liquid line service port. In this video i do not go into the details of superheat and subco.

In this hvac video, i go over what subcooling to set an air conditioning system to if the rating plate is worn off. How to calculate subcooling in refrigeration? How to check, measure, and read superheat and subcooling on a central air conditioner unit.

However, you must look for the proper design subcooling for the particular system. Take the head pressure and convert it to temperature on a temperature/pressure chart. Checking subcooling •liquid line service valve.

Add charge to raise subcooling. Check the digital thermometer for the thermocouple temperature. Use the dew point temperature on the pressure/temperature chart to obtain the evaporator saturation temperature for superheat, and the bubble point temperature to obtain the condenser saturation temperature to measure subcooling.

Now, convert the temperature reading to condenser saturation temperature using the refrigerant temperature chart. For example, water boils at. Subtract the liquid line temperature from the condensing temperature.

Recover charge to lower subcooling. For example, if suction line temperature is 65 degrees and your conversion of the suction pressure to temperatures yields. Measure with the pressure gauge.
