Common Questions About Ducted Evaporative Air Conditioning

When it comes to ducted evaporative air conditioning, Perth homeowners are often a little confused. The concept of this type of air conditioning differs from conventional systems, which may mean that you could be tempted to reject the idea of evaporative air conditioning installation. However, the answers to some common questions may help to relieve your anxiety and allow you to have all the facts needed to make an informed decision.

How Many Doors and Windows Need to Be Kept Open?

One of the biggest difficulties many homeowners have with evaporative systems is that you need to keep some windows or external doors open to allow the system to work effectively. This is necessary to allow the hot air to be released outside, as it is not drawn into an outside condenser. Most experts recommend that you open windows which are furthest from the ducts or vents. You should aim to create an opening twice the area of the vent opening.

Can the House Be Pre-Cooled:

If your system features a delay timer, it is possible to switch the system on before you arrive home, so it is the perfect temperature when you arrive. However, you will need some form of ventilation, so you will need to leave a door or window open. If you fail to have adequate ventilation, the house is likely to feel humid when you arrive, which will clear only when you open the windows. Obviously, if you are leaving doors or windows open while you are not at home, you will still need to ensure that your property is secured. This means that you may need to consider security screens or some other form of window covering that allows ventilation without allowing intruder access.

Can Different Areas be Cooled?

Most modern systems include a zone control feature. This allows you greater control over cooling in different zones or areas of the house. You can also change the configuration of which external doors and windows are open. The system is designed to function as cool air released from the vents takes a path of least resistance towards the outside air. This means that hot air is pushed out of the way. If you close a window but open the internal door, the cooled air will shift into another area where there is an opening through another window or external door. You can experiment a little with opening different doors and windows to see which provides the most effective cooling where you need it most. Just remember, that you need to ensure that there is always some form of ventilation at all times to avoid humidity.
