Evaporative Cooling Melbourne
Before we discuss how effective this air cooling technique is let us spend some time in understanding what evaporative cooling actually means.
Features of Evaporative Cooling
Evaporative cooling is one of the most natural ways of cooling air. It uses the simple laws of science which say when water evaporates from the surface, it cools the surrounding air.
The amount of energy spent during the process is minimal but the outcome is as good as cooling air using an air conditioner.
Our traditional air conditioners use the refrigeration approach. This process uses artificial air compressing fuel to compress the air, condense it and render cool air. This is good but in the long term it poses a great threat to the environment. The chlorofluorocarbons released during air conditioning weaken the ozone layer.
Evaporative coolers used in most homes and offices have a direct evaporation set up. In direct evaporation, the job of the cooler is to pull air into the pads located inside the cooler. These pads are moist and therefore the dry air drawn from the outside quickly works on the water present in the pads. As a result the moisture on the pads is evaporated and cool air is let out.
Benefits of using Evaporative Cooling
The environmental factors is one reason why evaporative cooling is a great alternative to air conditioning. As mentioned earlier the energy used is also not much so for anyone looking to save the environment and save big on electricity, this method of air cooling is ideal.

There are other types of coolers as well which use a secondary heat exchanger. This means they don’t follow the direct evaporation approach. Air is cooled as an indirect evaporation technique. The problem with these kinds of coolers is that they are not the most energy efficient when it comes to saving electricity. There are also coolers that combine both direct and indirect evaporation and use these techniques to cool the surrounding air.
Who is Evaporative Cooling suited to?
Evaporative coolers that use direct evaporation add a lot of humidity to the air. So, if this accentuates the humidity levels already existing in the air, the cooler can face frequent repairs. Depending on the kind of place you live in you should choose the evaporative cooler. For example in places that are highly humid, using a direct evaporation cooler is not the best thing to do.
On the other hand for people who reside in relatively dryer climates, using a direct evaporative cooler can work out to be a great cooling option.
Evaporative coolers have evolved over time. Initially they were known as the ‘swamp coolers’, which is because of the damp odor they left every time they were used. But today, there is a lot of improvement seen in the technology used in the coolers. Many people prefer these coolers to the traditional air conditioners.
However, before you get one installed talk to an expert about the installation and get his expert opinion on the functioning of the cooler.
