What is Evaporative Air Conditioning?

An evaporative air conditioner cools air through the evaporation of water, the system utilises a constant flow of water and air movement to remove heat from the air.

How does Evaporative Air Conditioning work?

The system cools air through the evaporation of water in the roof cavity.

This system requires a constant water source to work efficiently and works best if some doors and windows are open in order to draw the air through the homes zones

How is Evaporative Air Conditioning installed?

A unit is placed on the homes roof; ducting pipes are installed in the roofs cavity.

Ceiling vents then are placed in rooms where the air conditioning is required, creating a network for the cool air to travel through to cool the desired rooms.

Best Suited Application

To work effectively, evaporative air conditioners require some windows or doors to be open, this allows the hot air to escape to outside.

The best way to manage this is to open doors and windows that are furthest away from the cooling vents, allowing the cooler air to slowly make it way through the house forcing out the hot air.
