How Air Conditioning Systems Work
Air conditioners use fans to move interior air over a cold surface, usually comprised of grids or "coils" of copper or aluminum tubing. As the coils chill the air, its moisture condenses on the coils and is drained away.
The coils are chilled by a refrigerant that's pumped by a compressor through insulated lines to a condenser located outside. This process involves a phase change, where the refrigerant turns from a liquid to a gas at a low boiling point.
Warm air from the room is drawn into the system, where it passes over cold evaporator coils that absorb heat. Moisture in the air condenses on the coils and is drained away.
The cooled, dehumidified air is circulated back into the room, making it a more comfortable space. The absorbed heat is transferred outside through the condenser unit.
Here's a breakdown of the cooling process in an air conditioner:
- Warm air from the room is drawn into the system
- The air passes over cold evaporator coils, which absorb heat
