While most people, probably including you, are familiar with refrigerated air conditioning systems, the truth is there is another type of cooling that’s been in existence since the time of the Romans. Yes, evaporative cooling has been around for quite some time now, but why is it that many folks are not even familiar with it? Well, the answer is that everyone seems focused on the conveniences provided by refrigerated cooling, or the one used in indoor AC systems in residential settings.
But why should you be interested in evaporative cooling? The reality is it is an overlooked cooling system with many benefits that you deserve to learn. The way evaporative systems like Bonaire cooling units work is like that of a person swimming on a scorching hot day. Once that person gets out of the water, his skin feels the wind contacting the wet skin, thereby creating a cool sensation. That is how evaporative cooling works.
Evaporative cooling systems take advantage of the natural process of evaporation to provide a constant and sustainable flow of cool and fresh air inside or within a hot and dry outdoor or indoor setting. Interestingly, the concept of evaporative cooling has been in use for centuries already before the invention of refrigerants and the sophisticated AC systems.
Today, the typical evaporative cooler works by circulating water via a saturated component while at the same time drawing air in the surface of that same saturated component. Hot air naturally absorbs the moisture produced by the element, thereby effectively reducing air temperature. There is a modern water distribution system, like that of nozzles in Bonaire cooling systems, responsible for spreading water over the surface of the pad. The objective is to come up with a steady supply of water within the area covered. The fans attached to the cooling unit are the ones that will create a negative pressure, which in turn causes the air to be drawn via the pads.
The process of evaporation happens once there is contact between the water and air. Meanwhile, a control system, also incorporated in the evaporative cooler, will work by controlling the water pump, while the fan is the one that distributes the fresh air. Know that the lower the humidity in the environment, the better the results are with regards to maximising the evaporative cooling effect.
While it is true that both evaporative and refrigerated systems have the same purpose of keeping an environment cool, there is a considerable difference in a way that the former is effective for cooling outdoor areas and living space, while the latter is only intended for indoor environments. Evaporative coolers are ideal in situations where there is air circulation since it introduces fresh air. Also, it is proven that evaporative coolers require less maintenance and are a lot more energy-efficient compared to a traditional refrigerated AC.
