What is an Air Cooler?
Air coolers are also known as evaporative or purified coolers, and it cools the atmosphere by evaporating water. When air flows through water, some particles on the water’s surface will be blown away. These particles carry heat with them and cool the air. This is the main mechanism behind air coolers. With the help of this article, you will learn about how does an air cooler work.
The working principle of an air cooler:
Air coolers work on the evaporative cooling principle, where water evaporation is used to cool the air. One simple example of evaporative cooling is sweating in humans. When the sweat begins to evaporate, it draws out excess heat absorbed by the skin in the form of gas which results in the cold in the case of cold weather.
Many air cooler today come with dedicated ice trays, which helps to cool the water. This results in fast and powerful cooling. The best thing about using an air cooler is that you can leave the doors and windows partially opens to ensure fresh air is always circulating.
How does an air cooler work with water?
Sweating also acts the same way: water particles on the surface of the skin take away heat as it evaporates and cool the skin. These chillers are known to use 75% less energy compared to central air conditioners.
Evaporative coolers come in a variety of styles. Fine droplets are sprayed into the air and then blown out by a fan in some way because the water in this mist consists of small droplets. It will evaporate easily and absorbs heat from the air. Alternatively, the air is created to blow through the wet material. It can be blown through fine mesh or a wet sheet, for example. This wet material cools as it evaporates and cools the air.
Depending on the temperature, the air can only retain some humidity. When the temperature is higher than that amount, Water will begin to condense out of the air at the same rate as it evaporates. This leads to effective protection against evaporative cooling.
How will the Air Cooler work without water?
Direct evaporation is used in residential shift chillers and industrial conditions. This is explained by a metal or plastic inner box with side vents. Centrifugal fan or blower drives air, and the water pump will wet the evaporative cooling pad. The cooling system may be installed on the roof, exterior wall or window of a building nearby the exhaust fan through the vents on the side of the machine and the moisture-proof sheet to keep it cool. The heat in the air evaporates the water from the plates, which are continuously re-plated to continue the cooling process.
These two working principles will help to clear confusion about how does an air cooler work.
Incredible benefits of using an air cooler?
Energy efficiency: On average, air coolers use ten times less energy than conventional air conditioners, guaranteeing a significant reduction in consumer electricity bills. Some air coolers today also come with inverter technology which further reduces energy consumption. This technology saves up to 50% of energy and electricity costs compared to conventional air coolers.
An added benefit is that the inverter cooler emits much less noise due to the electronically switched motor and makes working and joining your video calls easier and more enjoyable.
Capital and recurring costs: AC has pre-purchase and installation costs or operating and maintenance costs. So the air coolers are much cheaper than air conditioners.
Environmentally friendly: Unlike ACs that use harmful chlorofluorocarbons (CFCs), air cooler use a natural evaporative cooling process with no carbon emissions, which makes them an environmentally friendly option.
Air quality: The air cooler circulates fresh air as it draws hot air from the outside and cools it. In addition, the circulating air is filtered to be hydrated and easy to breathe. It also keeps your skin hydrated. AC, in turn, circulates the residual air in the room.
Installation and portability: Unlike an AC that requires professional installation and works as a fixed unit. But air cooler do not need to be installed. All you have to do is fill the water tank and plug in the power cord. Plus, the air cooler is portable and can be easily moved around.
