Condenser Coil
The heat-exchange coil where refrigerant releases heat to the surrounding air.
Definition
The condenser coil is the heat-exchange coil where high-pressure refrigerant releases its heat to the surrounding air, condensing from vapor back to liquid. On a refrigerator, the condenser is on the back of the cabinet or in the bottom (with a small fan). On a central air conditioner or heat pump, the condenser is the outdoor unit. Keeping the condenser coil clean is critical to efficiency — even a thin layer of dust raises operating pressure, reduces cooling capacity, and shortens compressor life. Vacuum refrigerator condensers twice yearly and hose down outdoor HVAC condensers each spring.
