How Split System Ac Works
A split system air conditioner cools a room by moving heat outside. It has two main parts: an indoor unit and an outdoor unit.
These parts work together to keep your home comfortable in hot weather.
Indoor Unit Functions
The indoor unit blows cool air into your room. It has a fan and an evaporator coil.
The fan pulls warm air from the room and passes it over the cold evaporator coil. This cools the air before it returns to the room.
- Draws warm air inside
- Cools air using the evaporator coil
- Circulates cool air back into the room
- Contains filters to clean the air
Outdoor Unit Roles
The outdoor unit releases heat from your home to the outside air. It has a compressor and a condenser coil.
The compressor pumps refrigerant through the system. The condenser coil helps to remove heat from the refrigerant.
- Compresses and pumps refrigerant
- Releases heat outside using the condenser coil
- Contains a fan to cool the condenser coil
Refrigerant Cycle Basics
The refrigerant moves between the indoor and outdoor units. It carries heat out of your home.
The refrigerant changes from liquid to gas and back. This change helps it absorb and release heat.
- Refrigerant absorbs heat inside as it evaporates
- It travels to the outdoor unit as a gas
- Releases heat outside as it condenses back to liquid
- Cycles continuously to cool your home
