How Does Ducted Cooling Work?

Ducted air conditioning is becoming ever more popular in Australia. It’s affordable, effective, and suited to cooling larger areas with numerous spaces, making it an obvious option for anyone trying to find a new air conditioning system for their house.

How does ducted air conditioning work, exactly? In this short article, we’ll check out the science behind ducted aircon – how it works, the main equipment included, common questions, and more.

If you’re ready to get started though, Brampton Home Sales has had tremendous success using Sigrist Design for our residential ducted air conditioning. They have wonderful service and they’re a Brisbane based company which is always a positive.

What is ducted air conditioning?

A ducted air con unit consists of 2 systems: an indoor unit and an outside unit. The two units collaborate to perform a refrigeration cycle, with conditioned air flowing and provided through a series of vents and ducts. It’s normally the perfect system for bigger structures, due to its performance and ease of control.

How does ducted air conditioning work?

Ducted cooling is a refrigerated cooling system that uses refrigerants to change air temperature levels. Refrigerant is a compound that can easily alter between gas and liquid, and as it goes through this procedure, it changes temperature level. The ducted system uses this temperature level modification to cool or heat air that it pulls from your house.

The main components of cooled cooling systems are condensers, evaporators, and compressors. When on cooling mode, a streamlined variation of the refrigeration procedure in a ducted system works as follows:


Warm air is drawn out from your house with a blower, which it transfers through ducts to the evaporator coils in the indoor unit. These coils consist of cold, low-pressure refrigerant which takes in the heat from the warm air, and turns it into a high-pressure gas. As the warm air from your house blows over the evaporator coils, it ends up being cool, and is provided back to your house through vents/diffusers in the ceiling.


The high-pressure refrigerant gas flows through to the compressor in the outside system. The compressor pressurises the gas, which condenses it into a liquid.


The liquid circulates through to the condenser’s coils, also in the outdoor system. A fan blows over the coils, which dissipates some of the heat from the liquid refrigerant inside. The liquid then goes through an expansion valve, which depressurises and cools it much more, prior to being passed back to the evaporator to duplicate the cycle.

Other noteworthy elements of a ducted aircon system include:

  • The return air grill: this is where the air is pulled into your house.
  • Filter: the filter is located in the return air grille, and helps to filter dust, dirt, and other toxins.
  • Thermostat: the thermostat (or sensing unit) measures the temperature of the location being conditioned, enabling the system to adjust if essential.
  • Controllers: Controllers are where you adjust the system, and are typically mounted on the wall. You can manage the system from other devices such as your phone, tablet, or laptop if you have a ducted air conditioning system with smart features.

What are the zones in a ducted aircon system?

A ducted air con is a kind of central air that uses ducts to channel air throughout the system. With the use of ducts, the system has the ability to reach various locations of the house, which are called zones. In a larger property, you may have 4 different zones– one for the primary living location, one for the kitchen area, one for the master bedroom, and one for a smaller bedroom.

What is ducted reverse cycle cooling?

Ducted reverse cycle aircon units are able to reverse the refrigeration cycle, which permits them to both cool and heat a property. When the refrigeration cycle is reversed, the condenser ends up being an evaporator, and cool air is pulled into the system and transformed to heat. The majority of modern-day ducted air conditioners have reverse cycle ability.

What is a ducted inverter air conditioning system?

Inverter technology allows an air conditioner’s compressor to change speed. In older air conditioning systems, the compressor has two modes– on, or off.

What’s the difference between ducted air conditioning and split system cooling?

Ducted aircon and split system air conditioning both use refrigerated cooling to manage a building’s environment. The primary distinction is that ducted systems utilize versatile ducting to distribute and disperse air, whereas split systems utilize wall-mounted units that pump air directly into the space.

Ducted systems tend to be more suited to larger residential or commercial properties, where numerous areas are being cooled or heated up. Split systems are generally advised if you’re trying to cool simply one or two rooms, which you wish to set the temperature for separately.

Where do the systems of a ducted system go?

The indoor unit of a ducted system is typically installed in the ceiling cavity, however, it can often be installed below the flooring (if there suffices space).

The outdoor unit is positioned outside. It releases warm air from the system and also contains a fan (which can be a little loud), so tends to be placed far from any living space.

Should I Get A Ducted Air Condition System?

Ducted air conditioning units have been a popular option for Brisbane citizens for many years, able to handle the local weather conditions. The warranty a brand name provides for their ducted air conditioning unit is the 2nd thing to consider. A good ducted air conditioning unit service warranty ought to have a parts and labour period of at least 12 months.
