Condenser Sub-cool
Like the evaporator, the condenser is sized so that all the gas will be condensed
before the last few coils, the liquid temperature drops slightly below the condensing
temperature. In the case of an overloaded condenser or one short of refrigerant,
there will be little or no subcooling.
This is an example of temperature indications for normal operation and various
malfunctions for typical sir conditioning unit.
