Subcooling is a measurement of temperature decrease of a liquid below its saturation temperature at a given pressure. In refrigeration, the subcooling between the condenser and metering device provides a lot of information, including whether the line has liquid, refrigerant charge and condenser efficiency.

Checking subcooling

  1. From the unit data plate determine the type of refrigerant and recommended txv subcooling amount
  2. Check all of your hoses to make sure the O-Rings are intact and free from dirt, oil and debris
  3. Attach blue hose to the suction line service port (the larger the diameter line)
  4. Attach the red hose to the liquid line service port (the skinny line)
  5. Bleed Hose
  6. Attached tip of temperature probe to the liquid line near the condenser
  7. Allow unit to run for a few minutes while pressures stabilize
  8. Determine your high side saturation temperature
  9. Determine your liquid line temperature
  10. The numbers show – 84 degrees saturation temperature minus 74 degrees liquid line temperature equals 10 degrees of subcooling.

By graduation, ETI HVAC/R graduates should be well-prepared to start a career in an in-demand industry. Our hands-on training program is highly valued by Chicagoland companies, which is why we have well-established relationships with employers dating back 20 years.
