Choosing the right cooling system
When you consider that cooling accounts for a large proportion of household’s energy costs over summer, it’s so important to select the right cooling methods for your home. The wrong choice can prove both costly and uncomfortable.
The most important choice you have to make is whether you need to cool separate rooms or your whole home.
When it comes to cooling your whole home, you have the choice of two main systems: ducted evaporative systems and ducted refrigerated systems.
Ducted evaporative coolers use fresh air to cool all rooms of your home at the same time. Fresh air is drawn from outside your home through the water moistened filter which cools and cleans the air. The cool, fresh air is then circulated through the ducts, forcing stale air out through open windows and doors. This natural cooling process has low installation and low running costs, low noise and low greenhouse emissions, and is ideal for asthma and hay fever sufferers. All rooms in your home are cooled at the same time.
Ducted refrigerated systems use an outdoor compressor and an indoor fan coil to cool the air. They are connected to an insulated duct system which distributes the conditioned air through your home via floor or ceiling registers. Traditionally you’ll find these systems work on a day/night zone system which lets you cool the living areas of your home during the day and cool the sleeping areas at night.
If you only need to cool individual rooms in your home, then a refrigerated high wall split system is the way to go. This system works on the same principal as ducted refrigerated systems and consists of a condensing unit installed on the outside of your home, and a wall mounted unit inside your home. The air is artificially cooled through indoor and outdoor coils connected by pipes carrying refrigerant gas. For a low cost and easy to install option, Bonaire also has the Bonaire Durango, a window mounted fresh air room evaporative cooler.
Some important questions
- In a long hot summer, will I be comfortable just cooling one or two rooms?
- Do I want the comfort of having every room cooled?
- Should the purchase price be my biggest consideration?
- Do I need cooling all day or for short periods of time?
- Should I think about running costs?
- Will noise bother me or my neighbours?
- Does anyone in my house suffer from asthma or hay fever?
