How a Home Air Conditioner Works
Similar to how a refrigerator works, air conditioners transfer heat from a home’s interior to the warm outside environment.
Cooling coils remove heat and humidity from the air using refrigerant.
A blower (or fan) circulates air over the evaporator, dispersing the chilled air.
Hot coils release the collected heat into the outside air.
A pump that moves refrigerant between the evaporator and the condenser to chill the indoor air.
A fan blows air over the condenser to dissipate the heat outside.
Located in the air conditioning unit to remove particles from the air.
A control system to regulate the amount of cool air that is distributed.
