How Evaporative Cooling Works in 3 Simple Steps

How Evaporative Cooling Works in 3 Simple Steps


Evaporative cooling is a great way to cool any space. The technology behind it is very simple but delivers great results. Here we will demonstrate who it works in 3 simple steps.

1. Warm outside air is drawn into the evaporative cooler through wet filter pads by the ventilation fan.

2. The warm air passing through the wet filter pads makes the water evaporate. The heat needed to cause the evaporation is expelled, creating cooler air.

3. The ventilation fan then directs the cool air through to the areas being cooled.

This system works similarly to how the human body regulates temperature. If the human body is too hot it will perspire to create moisture on the skin. As air passes along the perspiration it evaporates, cools the skin and helps to lower the overall body temperature.

Warm air drawn into wet filter pads evaporates the water. If all the water evaporates then there is no way to cool the air. That’s why all evaporative coolers have pumps that continually draw water to wet the filter pads from the top down.

Unfortunately evaporative coolers can’t be used everywhere. Most of Australia is perfect for evaporative cooling except for the top end of Australia where there are high temperatures along with high to extreme levels of humidity at the same time.

Below is a video from Breezair that gives a more graphical view of how their evaporative systems work.
