The condenser, a hot outside coil, releases the gathered warmth outside. The evaporator as well as condenser coils are serpentine tubes surrounded by aluminum fins. This tubing is generally constructed from copper. A pump, called the compressor, relocates a heat transfer liquid (or cooling agent) between the evaporator and the condenser. The pump forces the cooling agent via the circuit of tubes and also fins in the coils.
The hot refrigerant gas is pumped outdoors into the condenser where it changes back to a liquid, surrendering its warmth to the outside air moving over the condenser's steel tubing and fins. Throughout the second fifty percent of the 20th century, almost all ac system used chlorofluorocarbons (CFCs) as their cooling agent, but since these chemicals are damaging to Planet's ozone layer, CFC production dropped in the United States in 1995.
