What is ducted air conditioning?
A ducted air conditioner consists of two units—an indoor unit typically installed in the ceiling, and an outdoor unit. The two units work together to perform a refrigeration cycle, with conditioned air circulated and delivered via a series of ducts and vents. It’s usually the ideal system for larger buildings, due to its efficiency and ease of control.
Ducted Air Conditioning
Ducted System provides discreet air conditioned comfort. It can be installed in a new home or tailored to suit an existing one, and once installed, only the controller, the return air and discharge grilles are visible inside your home.
We manufacture our own ventilation ducts at our factory. We therefore ensure the quality of our products.
How does ducted air conditioning work?
Ducted air conditioning is a refrigerated cooling system that uses refrigerant to change air temperature. Refrigerant is a substance that can easily change between gas and liquid, and as it goes through this process, it changes temperature. The ducted system uses this temperature change to cool or heat air that it pulls from the house.
The main components of refrigerated cooling systems are evaporators, compressors, and condensers. When on cooling mode, a simplified version of the refrigeration process in a ducted system works as follows:
Evaporator: warm air is extracted from your home with a blower, which it transfers through ducts to the evaporator coils in the indoor unit. These coils contain cold, low-pressure refrigerant which absorbs 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 becomes cool, and is delivered back to the house through vents/diffusers in the ceiling.
Compressor: the high-pressure refrigerant gas flows through to the compressor in the outdoor unit. The compressor pressurises the gas, which condenses it into a liquid.
Condenser: the liquid flows through to the condenser’s coils, also in the outdoor unit. A fan blows over the coils, which dissipates some of the heat from the liquid refrigerant inside. The liquid then passes through an expansion valve, which depressurises and cools it even more, before being passed back to the evaporator to repeat the cycle.
Other notable components of a ducted air conditioning system include:
The return air grille: this is where air is pulled into your home.
Filter: the filter is located in the return air grille, and helps to filter dust, dirt, and other pollutants.
Thermostat: the thermostat (or sensor) measures the temperature of the area being conditioned, allowing the system to adjust if necessary.
Controllers: controllers are where you adjust the system, and are usually mounted on the wall. If you have a ducted air conditioning system with smart features, you can control the system from other devices such as your phone, tablet, or laptop.
