WebNov 1, 2024 · Subcooling is an important measurement to take on any type of metering device in a comfort cooling system.” Tomczyk describes subcooling as measuring the difference between liquid temperature and the liquid saturation temperature at a given pressure. “A lot of people think it’s an amount, but it’s a measured amount,” he said. WebJan 11, 2004 · Steam at 213 degrees F is superheated by 1 degree F. Superheat is then any temperature of a gas above the boiling point for that liquid. When a refrigerant liquid boils at a low temperature of 40 degrees in a cooling coil and then the refrigerant gas increases in temperature, superheat has been added. If this refrigerant changed from a liquid ... Web4. Find the correct subcooling from the per-manent sticker inside the condenser unit, from manufacturer’s literature, or from a manufacturer’s slide rule. Add refrigerant if the measured subcooling temperature is 3°F or more below the recommendation. Withdraw refrigerant if the subcooling temperature is 3°F or more greater than recommended. biltwell motorcycle seats
