Evaporative coolers are one of the most energy-efficient, environmentally- friendly and affordable air cooling systems made available today. They are very low maintenance and are not so technical and complicated are traditional air conditioning systems. There are many kinds of evaporative cooling systems and they each have special functions that work well with different situations. Depending on the area you want to cool, you can choose one specific type of evaporative cooler.
In essence, all evaporative coolers work the same way. They all employ cooled water vapour for space cooling. Unlike typical air conditioning systems which use chemical-based refrigerants to cool the air, evaporative systems work as naturally as possible. The cooled water vapour is processed to moderate the temperature in you living or working space. Evaporative systems are very energy efficient and, at the same time, safe for the environment.
Types of Evaporative Coolers
There are two types of evaporative coolers. The first type is called the direct cooler. Direct here means that the ventilation comes into direct contact with the water. This is done by air/wind pressuring moisture off of a water pad, or through fan misting. The second type of evaporative cooler is called the indirect cooler. Here, a heat exchanger is used for cooling transfer to the ventilation. This makes it unnecessary for the ventilation to be in direct contact with the water.
Coolers like these are very common in the South. But depending on your climate, you might prefer one type of cooler over the other. The direct cooler contributes greatly to humidity. This is great for low humidity areas like highly-elevated locations or areas surrounded by desert. This is not so good for already-humid areas like hot coastal places. In this sense, an indirect cooler will be better. Whatever your space is like, there’s an evaporative cooler perfect for you.
