Introduction:

We take a look at the options available for keeping you cool in summer, from fans to airconditioners. There’s more ways to cool your home than just a ceiling fan, but in some climates it’s ideal. We look at the types of fans and airconditioners currently on the market.

Fans

Fans are the cheapest cooling device you can buy. The key to making fans work for you is to couple them with good insulation and ventilation.

Desk and pedestal fans

Desk and pedestal fans are effortlessly portable and plug into a standard wall power outlet. They come in a range of different sizes. They are a cheap way to circulate air through the home and should be used with external blinds, eaves and verandas on windows.

Ceiling fans

Ceiling fans require installation by an electrician, but are more efficient at cooling a room than other fans. In fact, they’re the most efficient way of keeping cool in hot and tropical areas.

Evaporative cooling

Evaporative coolers use a fan or blower to draw in outside air and pass it through a wet filter. As hot, dry air moves through the filter the water evaporates, cooling and humidifying the air. The cooled air is then blown through the room or house.

An evaporative cooler costs around half the price of a similar reverse-cycle unit. Running prices are considerably less, as little as 10 per cent the cost of reverse-cycle to cool a similar area.

Evaporative airconditioning is suitable for a number of situations. These include:

• Areas such as Perth which experience hot and dry conditions. Because evaporative airconditioners add moisture to the air, they are unsuitable for more humid climates.
• Evaporative coolers need windows and doors open to function and are ideal for families with children and pets coming in and out of the house regularly.
• Allergy and asthma sufferers may benefit from evaporative cooling. The system keeps air in the house moist, instead of dry as with reverse-cycle systems
