Duck and Cover with an air-conditioning unit in Adelaide

Ducted air conditioning is pretty much a lifeline for many Adelaide residents. No matter where you live during the summer months in Australia, air-conditioning can prove the different between changing once a day to change sweaty, damp clothing up to four times in a day.

Ducted reverse cycle air conditioning consists of an outside unit called a compressor and an inside unit placed within the roof. This internal unit is connected to a series of outlets within the house via duct work. Depending on the climate function chosen warmed or cooled air is pumped to all rooms that have an outlet.

The NSW office of Environment and Heritage explains how ducted air conditioners work. All refrigerated air conditioning systems, including reverse cycle air conditioners, are heat pumps (so are refrigerators). A 'heat pump' transfers heat from one zone to another. Heat pumps consist of an indoor and outdoor coil connected by a pipe through which a refrigerant circulates (note that refrigerants used are now CFC free). As warm air passes over the inside coil, heat from the air is absorbed by the refrigerant. This cools the air that is released back into the room. Meanwhile, the heat absorbed by the refrigerant is transferred to the external coil where it is released to the outside air. Reverse cycle air conditioners also work in reverse to provide heating. During the heating mode, heat is absorbed from the outside air and transferred via the refrigerant to the air inside your home. It doesn't have to be warm outside for reverse cycle air conditioners to work - they are capable of providing adequate heat when outside temperatures are below freezing.

There are two ways in which to keep your air conditioning costs to a minimum while helping to minimize the environmental impacts of using unnecessary power. The first device you must consider is a zone motor. The addition of zone motors in your home allows you to heat and cool selected areas within your house at any one time effectively allowing you to switch off air flow to areas not being used. It makes ducted reverse cycle systems more efficient and is often necessary for bigger homes as the ducted systems may not be powerful enough to heat and cool every room at once. Reverse cycle systems come in one, two or three phase systems depending on your heating and cooling needs. Zoning allows maximum flexibility and will help reduce running costs. The second device to incorporate is a compressor. Inverter technology refers to the ducted reverse cycle system’s compressor. The compressor is the working part of the outside unit. It operates by varying its speed in order to maintain a consistent temperature inside. The compressor will operate at maximum speed once the system is turned on until your preferred temperature is reached, then it will adjust accordingly to keep the temperature constant.

Another way to keep your home cool and fresh is the ducted evaporate cooling system. These operate by replacing stale old air with clean fresh air through a range of networked outlets installed into your ceiling. You can operate this system in summer but also in winter by just using the fan device to keep your home from becoming musty.
