More homeowners are switching to ductless ACs, and it is easy to see why. If you are also considering one, maybe you are wondering how a ductless AC works. Here is the guide you need to help you decide.
How a Ductless AC Works
Just from the name, you can tell that the ductless AC doesn’t need any ductwork to be installed. It is also called a mini-split, and it is ventless and specially designed for both heating and cooling. But how do ductless air conditioners work? Just like a conventional central AC, the mini split cools down your space by sucking in the air around. It takes in the heat and moisture and dumps it outside; then, in turn, it delivers cold air directly into the room.
However, the mode of operation is different because instead of using fans to help distribute the air, the system entirely relies on the indoor handler inside a particular room, cooling the air in that space. So, you will need to install more air handlers to cool the air in different rooms if you are not using central AC. What makes the mini split systems popular? It is because of their sleek design, energy efficiency, and versatility. You don’t need ductwork, and you can install them anywhere, whether on the walls or the ceilings.
What Are the Components of a Ductless Ac?
To better understand how a mini-split AC works, you should know about its three main components.
Evaporator / Blower
This is the part of the system that stays inside the house in the room where cool air is needed. It comes in a sleek and compact design, and its main job is to pull in warm air from inside the space. It absorbs the heat and moisture, taking those outside, and channels cooler air into the room.
Conduit
This component is the link between the internal and external parts of the AC unit. It is a thin tube that features a condensation drain, refrigerant tubing, and a cable. Its main function is to provide power to both parts of the mini-split, and at the same time, it is the corridor that transports heat and moisture out of the system.
Condenser
The last component of the ductless AC is the condenser, otherwise known as the external component of the system. It works by taking all the heat from the house and then unloading it outdoors.
