Evaporative Air Conditioner

What is an Evaporative Air Conditioner?

An evaporative air conditioner is a wonderful way to cool your home. It is cost-effective, eco-friendly, and works well in dry environments like Melbourne.

Conventional air conditioning works by using air already inside of your house, passing it through a fan coil that cools it down, before delivering it back into the house. Because of this, all windows and doors have to be closed so that the cold air will not escape. You would also have to wait for the air to get cold.

On the other hand, an evaporative air conditioner comprises a central cooling unit situated on top of your roof, that is connected to a series of outlets throughout your home. The unit draws fresh air from outside through a series of moistened pads, and as the air passes through these pads, water evaporates and the heat is absorbed. The filtered and cooled air then flows through the ductwork and into your rooms, allowing you to enjoy a fresh, cooling breeze.

Evaporative air conditioners also works best in rooms that have access to open doors and windows. This is to allow the air to escape, because the cooled air inside the building is not recirculated.

The system also requires a constant source of water, and only operates well in hot, dry climates like Melbourne.


Why Evaporative Air Conditioners?


Compared to refrigerated air conditioning, evaporative air conditioners are more cost-effective. Due to its design, the system uses significantly less power per hour, which translates to better savings on utility costs. It is up to 50% cheaper to install than comparable capacity refrigerated systems, and is also about seven times cheaper to run.


It is also eco-friendly, as evaporative coolers do not use CFCs, which have been said to affect the ozone layer. Evaporative air conditioners also uses less electricity than other forms of cooling, so it is kinder to our environment as its greenhouse gas contribution is a lot lower.

Fresh air that is not recirculated, providing an allergy-free environment

Evaporative air conditioning systems ventilate 100% fresh air, ensuring that you enjoy fresher and completely natural air. The air inside your home is not recirculated, which makes it not only a healthy way to cool your home, but also provides an allergy-free environment.

Provides cool, moist air

Traditional air conditioning systems can dehydrate your skin. An evaporative air conditioner, however, is based on a totally natural process of air cooled by water, which means it will not dry out the air, or irritate your skin, throat or eyes.

Keeps it cool even with doors open

On top of that, evaporative cooling systems keep your home cool even with your doors and windows open, leaving you free to enjoy summer in alfresco style! There is no need to lock yourself indoors to escape the heat!
