What Is a Ductless AC System? And How Does It Work?

A Ductless air conditioner system, also known as mini-split system, is a convenient way to cool when you need cooling in a limited area like individual rooms. 

A Ductless air conditioner can serve both purposes: heating and cooling service or just cooling. Ductless air conditioners and central air conditioners produce cool air in the same way. It sucks warm air and absorbs heat and moisture, then dumps heat and humidity outside. So, The main difference between them is that central air conditioners blow cold air through a network of air ducts from where it disperse to the whole place. While Ductless ACs blow cold air directly into a specific area without using air ducts.

How Does a Ductless AC system work?

Ductless ACs comprise two units: Indoor and outdoor units.

Outdoor Unit

The compressor - It is the most expensive part of an AC. It condenses low-pressure gas into high-pressure gas. So that the thermal heat transfer process completes effectively.

Condensing Coil - It comprises various aluminum fins. It cycles hot refrigerant and converts high-pressure gas to a high-pressure liquid.

The fan - It draws air from a condensing coil. It helps to throw stored heat energy into the surroundings.

Indoor Unit

The indoor unit comprises the blower and evaporator unit. It sucks in warm air and absorbs heat and moisture from the room. Then, it blows cold air into the room. It sends collected heat and humidity outside through conduit.

A conduit is a thin, long cable that connects an indoor unit to an outdoor unit. The conduit comprises refrigerant tubing, condensation drain, and power cable.

The outdoor unit pumps chemical coolant through refrigerant tubing into the indoor unit's coil. Then, the liquid coolant turns into gas. The indoor unit removes heat and moisture. Then, cold and less humid air is sent back to the room. The coolant gas flows to the outdoor coil. Here, it is converted back to a liquid, and heat energy gets released by the outdoor coil.

In a single zone ductless air conditioner, there is only one outdoor and indoor unit. In a multi-zone air conditioner, various indoor units can be connected to a single outdoor unit.

Advantages of Using Ductless ACs

Zoning - Ductless units provide zoning. Zoning means each room gets its remote control to adjust temperatures accordingly.

Duct leaks - In central air conditioners, some part of conditioned air gets lost in ducts. Ductless air conditioners prevent air leakage. It prevents loss of money.

Heat pumps - Air conditioners that comprise heat pumps can be beneficial for both heating and cooling purposes.

Inverter compressors - These compressors adjust to the system's need rather than shutting down the entire system.

Disadvantages of Using Ductless ACs

Maintenance - Ductless ACs require monthly cleaning of filters to get rid of dust and dirt.

Appearance - Generally, these air conditioners come in white and beige colors. These ACs do not come by your room design.

Price - Ductless ACs are quite expensive. You can hire air conditioning repairs experts for your air conditioning issues.
