The Key Components of an Air Conditioner Are:

  • Evaporator – Receives the liquid refrigerant
  • Condenser – Facilitates heat transfer
  • Expansion valve – regulates refrigerant flow into the evaporator
  • Compressor – A pump that pressurizes refrigerant

The cold side of an air conditioner is usually a furnace that contains the evaporator mounted above the fan that blows air over the chilled coils and into the room. The hot side contains the compressor, condenser and another fan to vent hot air coming off the compressed refrigerant to the outdoors. In between the two sets of coils, there’s an expansion valve. It regulates the amount of compressed liquid refrigerant moving into the evaporator. Once in the evaporator, the refrigerant experiences a pressure drop and expands and changes back into a gas. The compressor is actually a large electric pump that pressurizes the refrigerant gas as part of the process of turning it back into a liquid. There are some additional sensors, timers, and valves, but the evaporator, compressor, condenser and expansion valve are the main components of an air conditioner.

Although this is a conventional setup for an air conditioner, there are a couple of variations you should know about. Window air conditioners have all these components mounted into a relatively small metal box that installs into a window opening. The hot air vents from the back of the unit, while the condenser coils and a fan cool and re-circulate indoor air. Bigger air conditioners work a little differently: Central air conditioners share a thermostat with a home’s heating system, and the compressor and condenser, the hot side of the unit, isn’t even in the house. It’s in a separate all-weather housing outdoors. In very large buildings, like hotels and hospitals, the exterior condensing unit is often mounted somewhere on the roof.
