Condenser HVAC: Description and Operation

Function
The hot refrigerant is pressed into the condenser from above coming from the A/C compressor. Banks of tubes and louvers quickly absorb this heat. Exterior air is pressed or sucked through the condenser and heated up thereby cooling the refrigerant.

As the refrigerant is cooled down to a certain temperature dependent on the pressure, the refrigerant condenses and becomes liquid. The liquid refrigerant exits from the condenser at the bottom and flows into the receiver/drier.
