Everything To Know About Evaporative Cooling Method

Everything To Know About Evaporative Cooling Method 

In the summer seasons, different cities of Australia experience different weather conditions. For coastal cities, the high humidity in the atmosphere causes a lot of sweating and perspiration. However, if you move towards the inland cities, you will find the air deprived of humidity. As a result, in those areas, you will experience dry sweats.

With the variation of the weather, the artificial cooling systems have also been made separate. For humid areas, the best way to keep the environment cool is by installing an air conditioner. However, in the case of the dry regions, the AC won’t work correctly. In such cases, you need an appliance that works on the principle of evaporative cooling.

What Is The Process Called Evaporative Cooling?

Water has a high specific heat capacity because it can absorb a lot of heat energy without getting changed to the gaseous state. Similarly, it has a high latent heat capacity, allowing it to absorb a lot of energy from the surrounding to change its state from liquid to gas at the boiling point.

The entire evaporative cooling system works on this principle of the latent heat of the water. One kilogram of water can absorb 336-kilo joules of energy to form water vapor without the rise of any temperature.

How Is It Carried On Within The Cooler?

Now, since you have become familiar with the physics behind this process, let’s find out how the appliance works in a real-time scenario.

  • The fan inside the cooler draws in the air. This is the hot air of the atmosphere.
  • Once the air enters the appliance, it passes over the multiple layers of cooling pads. There is a water distribution center at the top of these pads which pour down the liquid. As a result, the water droplets stick to the surface.
  • Once the heated air passes over the droplets, water absorbs the air’s heat energy to evaporate. The loss of energy causes a decline in the air temperature, thereby making it cooler. This is the process of evaporative cooling.
  • The air is then expelled out of the cooler using an exhaust fan at the end.

What Are The Advantages Of This Cooling System?

Evaporative cooling systems are way more beneficial than the air conditioners, especially for cities near the Australian desert and the arid zones.

So, let’s discover the perks of installing an evaporative cooling system in your home.

  • Highly energy efficient: without a doubt, these cookers can save a lot of energy compared to the air conditioners. Here, water is recycled at every step, and hence there is no loss of energy. Also, since the cooling is done based on a natural phenomenon, the coolers don’t draw too much electricity.
  • Perfect for dry weather: since most parts of Australia suffer from a dry and non-humid atmospheric condition, you can say that the coolers are like angels in disguise. The cold air which is expelled out of the appliance contains moisture, because of which people can live comfortably. The moisture helps to keep the ambiance cool and dehydrated for at least some time.
  • Affordable: the coolers are way cheaper as compared to the air conditioners. As a result, if you’re running tight on your budget, you will be able to easily afford this cooling system and start living a comfortable life.


Understanding the entire evaporative cooling mechanism needs a lot of technical knowledge. At least, with this discussion, we hope you know the basics about the cooler’s operation and how they can benefit you during the dry seasons.
