Subcooling. Subcooling is the temperature below the condensing temperature of a substance. The condenser in an air conditioner is designed to reject the heat absorbed in the evaporator and added by the compressor. In the condenser, the refrigerant is condensed from vapour to liquid. The process is essentially the reverse of …

3. Calculate superheat: Subtract the saturation temperature from the suction line temperature (Suction Line Temperature – Saturation Temperature = Superheat). Example: If you have a suction line temperature of 65°F (18.3°C) and saturation temperature at 45°F (7.2°C), the superheat calculation will be as follows: 65°F – 45°F = 20°F ...Subtract the two numbers to get the subcooling. For example, 275 psi head pressure on an R-22 system converts to 124°F. The liquid line temperature is 88°F. Subtracting the two numbers gives 36°F. High superheat and high subcooling indicates a problem with the metering device.The difference of the two temperatures is the subcooling value.

For example, water boils at 212° Fahrenheit at sea level (atmospheric pressure of 14.7 PSIA). If water is 212°F and at atmospheric pressure at sea level, you can be sure it is at saturation, which means it ...A Subcool Superheat Calculator works by taking inputs such as the refrigerant type, pressure readings, and temperature readings at various points in the refrigeration system. These inputs are then used to calculate the subcooling and superheat levels, which are displayed as outputs on the calculator. For this example the Liquid line Temp is 95 degrees. Subtract the Liquid line Temperature from the Liquid Saturation Temperature and you get a Subcooling of 15. “Typically” on TXV systems the Superheat will range between 8 to 28 degrees with a target of about 10 to 15 degrees. The Subcool range on TXV systems will range from about 8 to 20. Superheat and subcooling are two important concepts in HVAC. Superheat is the number of degrees a vapor is above its boiling point at a specific pressure. Subcooling, on the other hand, is the number of degrees a liquid is below its freezing point at a specific pressure. By keeping track of both superheat and subcooling, technicians can more ...If the actual subcooling is higher than the target subcooling, the unit’s refrigerant charge level is overcharged.

Basically, superheat is the temperature a refrigerant vapor needs to maintain its gaseous state as it passes through the evaporator coil. While subcooling is the additional cooling that takes place in a condenser after the refrigerant has already been condensed. Here is a chart that contains low superheat causes and low subcooling causes: Indoor airflow (CFMs) is too low. Oversized AC unit. Outdoor airflow is too low (or condenser coils heat exchange is impeded). High refrigerant charge (overcharged AC unit). Metering device (TXV, AEV, or piston) is overfeeding.A solid understanding of superheat and subcooling is essential.
