What exactly is a condenser?

Written By

A condenser is the outdoor component of an air conditioner or heat pump that either releases or collects heat, depending on the time of the year. The condenser fan is a vital component and circulates the air across the coil to facilitate heat transfer. The compressor is the heart of the system since it compresses the refrigerant and pumps it to a coil in the form of a hot gas.

Both split air conditioners and heat pump condensers are made of the same essential parts that work together. The condenser cabinet contains the condenser coil, a compressor, a fan, and various controls. The condenser coil can be made of copper tubing with aluminum fins or all-aluminum tubing so heat can be rapidly transferred. Two of the main parts are the compressor and the AC condenser.

The compressor is the box outside of your home and the first step in cooling the air. The compressor’s job is to take refrigerant gas and compress it to a liquid that gets sent back inside the house and into the condenser.

The act of compressing gas creates heat, so a fan inside the compressor draws air on the sides to pass through the cooling coils and out of the top of the unit. You must make sure the coils are free of debris from trees, weeds, grass, and bushes. Clogging the coils with such debris will cause your unit not to work properly.

A compressor’s main job is to compress atoms and molecules into a smaller volume. The liquid that was sent into the condenser is now turned back into a gas through pressure falling. Raising the coolant temperature above outdoor ambient temperature causes heat to flow from the coolant into the outside air.

When the refrigerant is turned back into gas, its an endothermic reaction meaning heat is drawn from the air. AC Compressors only accept and compress the refrigerant in gas form from the heated refrigerant. The refrigerant enters the condenser as a high pressure, high-temperature gas, and leaves as a liquid. 

The condenser has cold coils, and the warm air from the house is sent over them to get cooled, then sent back through the ductwork into the home to cool your home. A condensers main job is to remove heat from a source.
