How Split Ductless Air Conditioning Works

Split ductless air conditioning operates on a simple yet effective principle. The system consists of two main components: an outdoor unit, also known as the condenser, and one or more indoor units, often referred to as air handlers. These units are connected by refrigerant lines, which circulate the cooling agent between the outdoor and indoor units.

The outdoor unit plays a vital role in the cooling process. It houses the compressor, which pressurizes and circulates refrigerant throughout the system. The refrigerant absorbs heat from inside your home and transports it to the outdoor unit, where it is released into the air. This continuous cycle ensures that your home remains cool and comfortable.

Inside your home, the indoor units are strategically placed in different rooms or zones to provide individualized cooling. Each air handler contains a fan and an evaporator coil. When the indoor unit is turned on, the fan circulates filtered air from the room, passing it over the evaporator coil. As the warm air comes into contact with the cold coil, the heat is transferred to the refrigerant, causing the air to cool down. The cooled air is then recirculated back into the room, while the heat extracted from the air is transported to the outdoor unit for release.

One of the key advantages of split ductless air conditioning is the ability to independently control each indoor unit. This zoning feature allows you to customize the temperature in different areas of your home, ensuring optimal comfort for everyone. For example, you can set a lower temperature in the living room during the day and a higher temperature in the bedrooms at night, saving energy and reducing utility costs.
