Brilliant Tips About How To Check Subcooling

Checking subcooling •liquid line service valve.

How to check subcooling. In this video i do not go into the details of superheat and subco. Subtract the liquid line temperature from the condensing temperature. In this hvac refrigerant charging video i explain how to check and measure the superheat and subcooling charging processes for r22 and r410a freon.

Measure with the pressure gauge. For example, water boils at. The difference is the amount of subcooling that is being performed.

I also go over how to figure out what ref. Take the head pressure and convert it to temperature on a temperature/pressure chart. Measure the pressure at the receiver.

How to calculate subcooling in refrigeration? Subcooling is a measurement of temperature decrease of a liquid below its saturation (mixed liquid/vapor) temperature at a given pressure. In this hvac training video, i show how to check the refrigerant charge using the subcooling method.

Check the digital thermometer for the thermocouple temperature. These are used as practice examples for learning. Recover charge to lower subcooling.

In this hvac video, i go over what subcooling to set an air conditioning system to if the rating plate is worn off. 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. When you deduct the condenser saturation temperature from the thermocouple temperature, you find your subcooling.

Next i provide 3 scenarios for technicians to figure out. For example, if suction line temperature is 65 degrees and your conversion of the suction pressure to temperatures yields. However, you must look for the proper design subcooling for the particular system.

Now, convert the temperature reading to condenser saturation temperature using the refrigerant temperature chart. How to check, measure, and read superheat and subcooling on a central air conditioner unit. Wrap your thermocouples with insulation to obtain accurate pipe temperatures.

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