How Ductless Mini-Split Systems Work

Also known as ductless heating and cooling systems, mini-splits allow you to effectively control your indoor area’s temperature. Mini-splits function similarly to most central heating, ventilation, and air conditioning system. However, there are some distinct differences in the way that a mini-split operates. To learn more about how ductless mini-split systems work, continue reading.

The basics

Rather than controlling the temperature of an entire home through a duct system, mini-splits only cool the room that they are located in. That being said, mini-splits can still heat or cool an entire home as multiple indoor units can connect to a single outdoor unit. As such, each individual room will require an indoor unit, which will control its temperature rather than using ducts to push and pull air to a central unit.

The process

In order to understand how a mini-split works, it’s important to be familiar with the different parts of the system and where they are located. Ductless mini-split systems have three main components that facilitate their operation:

• Blower or evaporator unit: Also known as an indoor unit, the blower or evaporator unit is located inside the area that is being heated, cooled, or ventilated.
• Conduit: The conduit is a long, thin cable which connects the blower to the condenser. It is responsible for housing refrigerant tubing and the power cable which powers the indoor and outdoor units.
• Condenser: Also known as an outdoor unit, the condenser is located outside the area that is being heated, cooled, or ventilated.

When cooling a home, the first step of the temperature control process is carried out the blower or evaporator unit, which sucks in warm air from inside your home. Such air is then blown over cold evaporator coils, which include refrigerant, that absorbs the air’s heat. After the heat is absorbed, the resulting cool air is then blown directly back into the home.

To get rid of the heat and moisture that the refrigerant absorbed, it is passed through the conduit until it reaches the condenser, which is located on the outside of the home. Once the heat and moisture reach the condenser, they will be released into the outside air.

When heating an interior space, a similar process is followed except heat is pulled from the air outside and then released into the home to warm the space.
