How Do Air Cooler Work? The Science Behind the Chill

If you are living in a hot and dry climate area like the Terai region in Nepal, you must be using some kind of electrical device to relief from heat. Many people tend to use air coolers and also might wonder, how do air cooler work without consuming high power.

The air cooler is one of the best cooling solutions for a home because it provides a natural and energy-efficient way to cool down. That’s why the air coolers, coupled with ceiling fans, are quite extensively used to make a room livable on very hot summer days. Well, it becomes simple: use an air cooler.

There are many varieties of coolers and fans are available in the market. Among the coolers, some of them are room air coolers, personal coolers, tower coolers, window coolers, and desert coolers. Air coolers are eco-friendly as they do not use refrigerants or chemicals for cooling the air.

In addition, they do not let out harmful gases or pollutants. They are more pocket-friendly; one can get good quality air coolers for Rs.10000 or less.

Even though air coolers are widely used, many people don’t know how they work. Whether you already have one or are thinking of buying one, understanding how an air cooler operates can help you use it better and make it last longer. 

What is an Air Cooler?

Want to know how do air cooler works? Before getting into the details, it’s good to know what this appliance can do for you, especially during summer.

An air cooler is a device designed to cool the air in a room or outdoor space. It does this by drawing in hot air and then passing it over wet pads. As the water in the pads evaporates, it cools the air. This cooled air is then blown into the room, making it more comfortable. The process continues until the desired temperature has been reached.  

What really makes air coolers so popular for beating the heat without heavy spending is that they are much more energy-efficient than air conditioners. 

How do Air Coolers Work with Water?

Air Coolers use water to cool the air through the process of evaporation. Here is how it goes: 

• Water is stored in a tank inside the air cooler. 
• Finally, evaporation follows through the cooling pads soaked in water that the cooler draws warm air from the room and passes through. 
• While air is passing through the pads, the warmed air evaporates the water; the latent heat of evaporation is taken from the air. 
• This is then blown out into the room by a fan, reducing the general temperature. 

How will the Air Cooler Work without Water?

Using an air cooler without water is not recommended because it works by evaporating water. However, these are the steps you can follow if you really want to use it without water: 

Step 1: First, turn off your air cooler and unplug it from the power outlet.

Step 2: Remove the water tank and drain all its contents. 

Step 3: Remove the cooling pads and allow them to completely dry up. 

Step 4: Reinstall the clean cooling pads. 

Step 5: Now turn on your air cooler and set your desired fan speed. 

Without water, this air cooler will essentially become a regular fan – blowing air around and creating a light breeze. However, this kind of operation can cause overheating of the unit, damaging the motor and other parts. It is best to use the air cooler with water for the desired cooling effect. 

How do Air Cooler Work? The Evaporative Cooling Principle

Air coolers work on evaporative cooling. It is the natural process wherein water absorbs heat while changing from liquid to gaseous state. Now, the working principle of an air cooler can be explained by the following steps: 

1. Warm Air Intake: The air cooler sucks warm air from the room. 
2. Cooling Pads: The hot air enters the cooler and is fed through the cooling pads, which are soaked in water. 
3. Evaporation: Water content in the cooling pads evaporates, taking away some of the heat from the air. 
4. Cooled Air Output: Part of the air is cooled and blown out into the room by a fan, reducing its temperature. 

Advantages of using an Air Cooler?

An air cooler has several advantages, particularly during hot and dry climates with a low level of humidity.

i. Energy Efficiency:

The power consumption of an air cooler is less than that of an air conditioner, and therefore a person can save up to 80% of energy expenses by using the former.

Secondly, an air cooler can easily run on inverters or generators during power cuts without requiring any stabilizer or voltage regulator. Now, there are several other advantages of using an air cooler over an AC. 

ii. Cost Effective:

It is cost-effective in the sense that the purchase and maintenance of an air cooler are not as expensive as an air conditioner, and it requires no installation or ducting. Further, an air cooler can be more durable than an air conditioner and doesn’t require any servicing or repairing. 

iii. Environmentally friendly:

An air cooler does not use any refrigerant or chemicals for cooling the air and does not release harmful gases or pollutants that may affect the environment or the users’ health.

It also utilizes natural water as a coolant, which does not diminish the level of the ozone layer or Global Warming. 

iv. Air Quality:

This air cooler does the job of circulating fresh air by drawing hot air from outside and cooling it down. The air circulated by it is filtered and, therefore, more hydrated to breathe in. It will help to keep your skin moist. An AC will only circulate the same air inside the room. 

v. Installation and Portability:

While an AC requires professional installation and is fixed in one place, no such installation is required in the case of an air cooler. You simply fill up the water tank and turn it on. Moreover, the air coolers are portable and can be easily carried from one room to another.
