Once the air gets to the condenser, it will remain at its top and not condense. The subcooled liquid seal at the condenser's bottom will prevent the air from passing out of the condenser. This air and water vapor will take up valuable condenser surface area and cause high-head pressures. WebJan 11, 2016 · Remember, the condensing pressure is the pressure at which the refrigerant is changing phase from a vapor to a liquid in the condenser. There is a pressure-temperature relationship with the condensing pressure because of the phase change.
