This is a question you may be asking yourself if you’re considering an upgrade to your current air conditioning system, or simply want to know more how ductless air conditioners operate.
A ductless air conditioner works like a regular central air conditioner, but without the ducts. In a regular system, the indoor unit for the AC would be in an attic or closet, and the air would be transported to and from the unit by ducts. However, with a mini-split ductless system, the smaller unit is directly on the wall in a room and the air circulates directly into the space of the room.
There are many benefits of using a ductless AC, including that they’re versatile, don’t create much noise and offer enhanced levels of comfort.
Read on to discover more about how ductless air conditioners work and how they can benefit you.
How Does Ductless AC Work?
A ductless AC runs similar to a regular AC in that:
- The refrigerant absorbs heat from the indoor air and turns it into a high-pressure gas. This results in cooler air being pushed back into the living space by the internal blower.
- The low-pressure gas is transformed into high-pressure gas by the compressor. At the same time, the heat is dissipated into the outdoors by a forced-air fan.
- The low-pressure gas that’s left is moved through the suction line back to the compressor, where the cycle repeats itself.
There are two main elements to a ductless AC. These are the indoor and outdoor units.
- Ductless indoor units have a fan and evaporator coil which is housed in the same enclosure. Each of these units provides air conditioning wherever it is installed. Units can be strategically positioned to heat and cool one room, or an entire building.
- The indoor unit blows warm air from your home over cold evaporator coils. Heat is absorbed from the air through the refrigerant running through these coils and brings it to the outdoor unit.
The outdoor unit is where the refrigerant dumps all of the heat that is pulled from your home’s air. There are three components to the outdoor unit:
- Compressor: This is the most integral part of any air conditioning system. Its job is to condense low-pressure gas into high-pressure gas, making the thermal heat transfer process more efficient.
- Condensing Coil: This coil cycles hot refrigerant and helps it convert from a high-pressure gas to a high-pressure liquid.
- Fan: This draws air through the condensing coil and disperses stored heat energy into the outside space.
Ductless AC systems come in a range of styles including wall mounts, duct mounts, and ceiling cassette varieties. They generally have quieter operation and offer more comfort than a duct-dependent air conditioner. Through exclusive inverter technology, they also have the highest SEER rating (Seasonal Energy Efficiency Ratio) in the industry.
