Best Answer

It increases the efficiency of the system since the amount of heat being removed per pound of refrigerant circulated is greater. In other words, you pump less refrigerant through the system to maintain the refrigerated temperature you want. This reduces the amount of time that the compressor must run to maintain the temperature. The amount of capacity boost which you get with each degree of subcooling varies with the refrigerant being used.

Subcooling is beneficial because it prevents the liquid refrigerant from changing to a gas before it gets to the evaporator. Pressure drops in the liquid piping and vertical risers can reduce the refrigerant pressure to the point where it will boil or "flash" in the liquid line. This change of phase causes the refrigerant to absorb heat before it reaches the evaporator. Inadequate subcooling prevents the expansion valve from properly metering liquid refrigerant into the evaporator, resulting in poor system performance.

How do you calculate the subcooling in HVAC?

To calculate subcooling in HVAC, you need to measure the liquid line temperature and pressure. First, convert the pressure into temperature using a temperature-pressure chart. Subtract the liquid line temperature from the converted temperature to calculate the subcooling. Subcooling is important to ensure the liquid refrigerant leaving the condenser is cooler than its saturation point to prevent the formation of flash gas in the metering device.
