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.

Which is better vertical or horizontal condenser?
Hi.. For only filmwise condensation, horizontal position gives higher condensation coefficent than verical position. In case of condensation with subcooling in a shell and tube heat exchanger, condensation coefficient is higher with horizontal postion while subcooling coefficient is higher with vertical position. kal....
How subcooling increase the COP of vapour compression refrigeration?
The sub-cooling or under-cooling in the saturated liquid line increases the refrigeration effect or cooling effect, thus the COP of VCR system increases.
