How To Measure Subcooling In Refrigeration Systems

To check subcooling, connect a temperature probe to the inlet and outlet lines of the condenser. Measure the temperature difference between the two points using a digital thermometer. Subcooling is the difference between the saturation temperature of the refrigerant at the condenser pressure and the actual temperature of the liquid refrigerant leaving the condenser. A higher subcooling temperature indicates that the liquid refrigerant is cooler, which can improve system efficiency. Optimal subcooling typically ranges from 10-12°F (5-6.6°C).
