air conditioning and heating - how an ac works graphic
  1. Evaporator – Cooling coils remove heat and humidity from the air using refrigerant.
  2. Blower – A blower (fan) circulates air over the evaporator, dispensing the chilled air.
  3. Condenser – Hot coils release collected heat into the outside air.
  4. Compressor – A pump that moves refrigerant between the evaporator and the condenser to chill the indoor air.
  5. Fan – A fan blows air over the condenser to dissipate the heat outside.
  6. Filter – Located in the air conditioning unit to remove particles from the air.
  7. Thermostat – A control system to regulate the amount of cool air that is distributed.
