How Ductless Mini-Split AC Systems Work

Are you curious about how ductless mini-split AC systems keep your home cool? 

These innovative systems are designed to provide efficient and flexible cooling with minimal hassle. Understanding their components and functioning mechanisms can help you appreciate their advantages over traditional air conditioning systems.

 

Explanation of the Components

A ductless mini-split AC system comprises three main parts:

1. Outdoor Unit: This houses the compressor and condenser, responsible for cooling the refrigerant.
2. Indoor Unit: Mounted on the wall or ceiling, this unit contains the evaporator and air handler, which distribute cool air into the room.
3. Refrigerant Lines: These connect the indoor and outdoor units, allowing the refrigerant to flow between them. The lines are typically narrow and require only a small hole in the wall for installation.

 

Functioning Mechanism

Here’s how a ductless mini-split AC system works:

1. The outdoor unit compresses and cools the refrigerant.
2. The refrigerant travels through the lines to the indoor unit.
3. The indoor unit’s evaporator coil absorbs heat from the indoor air, cooling it down.
4. The cooled air is then blown into the room, providing comfort.
5. The refrigerant, now warm from absorbing indoor heat, returns to the outdoor unit to release the heat and start the cycle again.
