What is a mini split air conditioner?
A ductless mini split air conditioner system includes two basic components, both of which are found in HVAC central air units, portable air conditioners, and window air conditioners. The difference is that they are separated, or “split,” for the purposes of delivering cooling capacity to areas not reached by ductwork.
The first component is the actual cooling unit that is mounted on the wall inside the home.
In some cases, it can be attached to the ceiling, such as the Pioneer Mini Split Ceiling Cassette. Inside mini split systems include a cooling coil and an air handler to draw in warm air so it can be cooled and then re-released back into the room.
As you can see on the mini split systems above, units are mounted high in the room so they can capture warm air that rises and send cooler air downward, creating a balanced temp throughout the room or zone.
The second component is located outside the house and consists of a compressor that delivers refrigerant. It is typically mounted outside the home or building.
How mini-split units connect
Connecting the two units is accomplished with a small diameter conduit through which the coolant is delivered, and power is run to the individual air handlers. The conduit also contains a condensate drain to remove moisture.
Most ductless mini-split systems include an adjustable temperature function with w/a remote control or mobile app. From my research, “smart” mini split air conditioners and heat pump systems will cost 10-25% more than non-smart units.
