The Science Behind Evaporative Cooling in Australia

If you’re looking for an efficient, eco-friendly and highly effective cooling solution for your home or office in Australia, evaporative cooling is a great option. Here at GJ Bradding, we’re the experts in evaporative cooling Geelong homeowners and businesses have relied on since 1989. Below we explore how evaporative cooling works and its benefits.

Evaporative Cooling vs Traditional Air Conditioning

Traditional air conditioning systems work by taking air already inside of your house and passing it through a fan coil that cools it down before delivering it back into the home. Evaporative cooling, meanwhile, cools the air by drawing in the surrounding air from outside via a cooling unit. This often sits on top of the roof and is connected to a series of outlets, or ducts, placed throughout the building. 

We all know the feeling of experiencing a cooling sensation when misted with water on a hot, dry day. Evaporative cooling essentially uses that same principle to cool the inside of your home or commercial building. The effect requires two elements - moisture and airflow. 

Cooling Via Wet Pads

In evaporative cooling systems, a constant flow of air is filtered through wet pads or quilts, creating cool, refreshing air. These cooling pads are manufactured with fluted cellulose sheets glued together. The material is chemically ingrained with special compounds that prevent rotting while ensuring a long service life. A special distribution system evenly spreads water over the surface of the pad to achieve a uniform supply of water, so the entire air contact surface is thoroughly moistened. 

Fan Distribution 

Fans create the negative pressure required to draw cool air through the wet cooling pads. Evaporation results from contact between air and water. A control system operates the system’s water pump and the fan distributes the cool air. The lower the humidity, the better the evaporative cooling effect. Since the relative humidity is lowest in the afternoon when the temperature is at its highest, the cooling effect functions at its best when you need it the most.

Benefits of Evaporative Cooling

Evaporative cooling helps Geelong homeowners and businesses enjoy the cool air without the dry air effect that can be common with other air conditioning systems. Evaporative cooling installations can also be up to 50 per cent cheaper and uses only a third of the energy a refrigerated cooling system uses. By using water instead of harmful refrigerants, evaporative cooling systems are also better for the environment.
