The evaporative air cooler also known as a swamp cooler makes use of a different technique to cool the air. This method is known as evaporation which it does by releasing tiny droplets of water as it blows air. The body also makes use of a similar method to cool naturally by sweating and relying on the breeze to cool down the body temperature but sometimes, it is just not enough which is why you need something that is powerful enough to give air even when the air available is hot. It is different because it is the only cooling system that makes use of a more natural method to provide cool air.
There are other cooling systems and they all perform well enough to the best of their ability. However, the evaporative air cooler is somewhat different when you compare it. It does not make use of compression or any other chemicals to ensure the availability of air. It makes use of a tank filled with water and pads which is used to filter the air coming into the cooler to prevent dust and particles making the air so fresh that it gives your home a better smell. It also cools you down instantly because water has the ability to bring down the temperature of a person quickly. Water is also one thing that can absorb heat quickly or quench the fire, little wonder why it is the main ingredient needed to quench any fire outbreak.
With hot air comes the absence of water in the atmosphere which is why the air suddenly becomes dry. The evaporator helps to replace the air that is not available in the atmosphere by making water available when it blows and bringing down the high temperature to normal, unlike other cooling systems. The evaporative air cooler does not need to be installed before it can be used. This is because of how it was made and it is not expensive when compared to other cooling systems. You do not need to pay extra to get someone to help you fix it because it is already fixed and all that is left is to make sure that you have access to water because it is the one thing that makes it really different from others. It needs water to cool the air properly. It also needs the water to extract the dry air effectively since the pad has to be damp and it is what acts as the filter.
