+55 How To Measure Subcooling
How To Measure Subcooling - This check will determine if your subcooling calculation falls within a proper range. Take the head pressure and convert it to temperature on a temperature/pressure chart..

In This Article, We Will Define Subcooling, Calculate Subcooling, Explain How To Use Subcooling To Check The Refrigerant Charge, And Show Where The Measurement Points Are Taken On An Air Conditioning System.
Connect the refrigerant range gauges to the service discharge valve, and the pipe clamp thermocouple to the refrigerant line between the condenser discharge and. To measure the temperature, strap the thermometer's probe on the liquid line approximately six inches from the expansion valve and record the results. We use dew point for calculating the superheat and bubble point for calculating the subcooling.
It Is Essential That A Service Technician Be Able To Accurately Measure
Hvac/r training video.how to calculate superheat and subcooling on your air conditioner or refrigerator? To measure suction superheat, attach your gauge manifold to the suction service port on the outdoor unit. This liquid is referred to as a refrigerant.
Understand Heat And How To Measure Heat.
Measure subcooling run the refrigeration system until stable temperatures are reached. This check will determine if your subcooling calculation falls within a proper range. For example, water boils at 212° fahrenheit at sea level (atmospheric pressure of 14.7 psia).
(On Pressure Gauge) Convert The High Side Pressure To Temperature By Using The Pressure/Temperature Comparator.
Superheat and subcooling are also temperature differentials. To check subcooling, attach a thermometer to the liquid line near the condenser. That is, each is the number of degrees a gas or liquid is above or below its saturation temperature.
Ideally, You Should Consider Measuring The Subcooling In Addition To The Superheat.
Subcooling is part of a process used to remove heat from a designated area. Using table 3, you can check the range of subcooling by taking a wet bulb reading at the evaporator and a dry bulb reading from the air entering the condenser. Record the actual temperature of the liquid leaving the condenser with a surface temperature probe.
