The heat of Indian summer is tough to beat without the proper care. You should be drinking the right amount of water, avoid working in the sunny area to prevent the heat stroke.
But many time taking these steps only helps to a certain extent and in such conditions majority of people choose to buy the best air cooler.
The air cooler is an electronic gadget that helps to reduce the heat in the house by lowering an air temperature by dissipating technique.
Though air cooler does not provide as cooling as the Air conditioner, they are way cheaper than the AC and give a right amount of comfort to the users.
The Indian market has several leading brands that make quality air coolers which can be brought without worrying about its overall quality.
Though it is believed that the air cooler is invented by ‘Willis Carrier’ during the early phase of the 20th century, mankind is known the technique to cool down the air so that they can beat the heat.
Air cooling techniques date backs to an ancient civilization and some ancient paintings show that people of that era used water to cool the air.It is clearly known that water played a crucial role in cooling down the hot air and this system has been used continuously and improved upon until man able to develop the air coolers that we use nowadays.
How does air cooler works?
As the name suggests, air coolers are used to cool down the air by reducing the air temperature by dissipating heat. It exactly works like a cool breeze at the seashore.
Air cooler blows the air past the water and along the way this air carry small particles of water. These particles then get evaporated and carry some heat with them reducing the temperature of the air.
As we discussed earlier, coolers use evaporation water to cool down the air and often they are termed as swamp coolers or desert coolers.
While the water evaporates, it changes the state from liquid to the vapor and while doing so heat from the air is utilized leaving a cooling effect behind.
To achieve this, coolers are built using various parts as follows:
Fan & Vents – Fan is used to push the cool air in the room through the vent.
Water tank – Evaporative air cooler has a special tank to store the water. The user can fill or empty the water tank according to their need.
Cooling pads – Cooling pads are specially designed pads which have a porous structure. They are connected with water tank and absorb the water and allow air to pass through it.
Distributor and pumps – Often, air cooler has pump or distributors to distribute the water across the cooling pads.
Advantages of Using Air Coolers:
Air cooler comes with several benefits. They are a cost-effective solution to beat the heat, does not require installation and environment-friendly.
Cost effective gadget
As compared to air conditioners, air coolers are cheap. Also, in long run, they require a less operational cost.
The main thing that reduces the cost of an air cooler is its evaporative cooling mechanism, it takes less energy for evaporative cooling. While AC requires more electric power and chemicals that convert gas to liquid and back to gas which increases operational cost.
Like the table fans, the air cooler is a portable device and it doesn’t require any installation. You can easily move it from one room to other.
Once you buy it, you can assemble the basic things, add water and plug it to the electricity to start getting a breeze. To make it easy to move from one place another, most air cooler brands add small wheels at the bottom.
East to Maintain
Air coolers work on simple mechanism so doesn’t have any complicated parts or mechanism in place. This make it easy to maintain them in long term.
Also, any one with basic knowledge about working of cooler can open it and see what thing went wrong if it malfunctioning.
The spare parts of air coolers are readily available in market and relatively cheap than that of air conditioners spare parts. It can operate without stabilizers.
Good for people with respiratory symptoms & dry skin
Dry air can lead to dryness of skin and respiratory system causing the respiratory symptoms worse. Air coolers work by humidifying of dry air, which enhance the moisture of room.
This goes easy on the people with dry skin and respiratory symptoms. Though, this should not be taken as a treatment approach but it is better than having AC in the room for people with respiratory symptoms.
Air coolers does not require any specific chemical or gas for its functionality. Instead it utilizes the dry air and pass it over the water adding moisture to the air.
They does not emit any gas and do not have any negative impact on environment.
Disadvantages of Air Coolers
Though air cooler has several advantages, it comes with few disadvantages that you shouldn’t ignore.
Not designed for coastal regions
As it work by enhancing the humidity of air, it works better in the region with dry air & less humidity. Areas with high humidity and air pollution make it’s use a bit difficult. It will worsen the humidity.
Water droplets carried out by the air from cooler get evaporated due to higher room temperature and dry air resulting in the reduced room temperature after some time.
But in coastal regions, ambient air has more humidity which makes it difficult for the air droplets from the cooler to evaporate. Even if it gets evaporated, over the time the humidity level of room increases and water vapors begins condensing over the surface of your body.
Need water and Ice for Cooling Effect
To achieve maximum cooling effect, air coolers demand the cold water and ice. If you add the both, they cool sown the room fairly early.
But if you use the room temperature water, it will take much longer to cool down the room. So, if you do not have freeze to keep cool water, and ice then air cooler will not provide optimum cooling.
No control over cooling
You cant control the room temperature as desired because it just blow out the air with tiny water droplets. Air coolers are not conditioners, so you cant change the condition of room air as you desire.
Air coolers uses water recirculating pump and blower motor to run the equipment efficiently. But this results in to noisy operation.
If you compare the one with air conditioner, you will find the air cooler makes a lot of noise than the AC’s.
Types of Air Coolers –
Air coolers are broadly divided into the two categories.
- Personal air cooler
- Desert air cooler
Apart from these two, nowadays you can get one more type of cooler which is named as ‘Tower air cooler’.
Though the function of all types of cooler is the same, there is a small difference for which they are used and their features.
Personal air coolers
Personal air coolers tend to be used to cool small to mid-sized rooms while deserts coolers are useful to cool the medium to large size of rooms.

They are more robust than the personal one. The deliver betters results, and can be used to cool the bigger rooms.
Everything pertaining to the desert coolers in big as compared to personal coolers. They utilize bigger blower motor, bigger fan which may results in to the more electricity bill.
Tower air cooler
As name suggests, these air coolers has an extra length than their width. Also, they are more quite than the desert air coolers.
They work using the same functionality but distributes the air vertically which make it useful when person is seating on a chair or at a certain height from the ground.
Tower air cooler works same way like other air coolers. They utilize the dry air and pass it over cool water blending it with tiny water droplets which then blown out in the room to cool down the room.
How to Choose Air Cooler in India? – Buying Guide
Size Matter Most
Choose the right size based on the size of your room.
For air cooler to work efficiently, it should be proportionate with room size. Because the air flow from the cooler will be measured considering the CFM which means “Cubic feet per minute”
The CFM will give you an idea about what capacity you should choose. More CFM means more air flow and it is calculated as follow –
CFM = Area of the room * Height of the room/2
Water Tank Capacity
Larger water tank mean longer operation of air cooler
The function of an air cooler involves the evaporating cooling method. Which means it passes the dry, hot air over the water and wet pads lowering the temperature of air. This cool air then blown out.
Air cooler require good amount of cold water to keep the functioning for longer duration. So, larger water tank helps to achieve that.
Cooling pads plays important role
Honeycomb cooling pads are more efficient, require low maintenance & has longer life
Cooling pad is one of the most important part of air cooler that helps to cool down the air. They absorb dry, hot air and allow it to pass over the wet surface to cool it down.
Aspen and Honeycomb are the two major types of cooling pads used in air coolers. Aspen pads make use of synthetic fibers & wood shavings while honeycomb utilizes the cellulose.
Though both cooling pads has their pros and cons, Aspen cooling pads have shorter life, require high maintenance but are cheaper than that of honeycomb.
Consider aesthetic design
Choose the sleek, stylish and minimalist design that fits with your room interior.
Usually, design is one major factor why people avoid buying the air coolers. They occupy space as well as doesn’t go well with the interior of room.

Things like remote control, ice-gel packs, better control panel needs to be looked for while buying air cooler.
Some air cooler comes with remote control for ease of use. In such case you need to pay attention to the control panel and what function it allows you to use with remote control.
Few brands now includes the ice-gel packs with the cooler while some allow to add the ice cubes in a specially dedicated tray for ice. Adding ice will greatly enhance effect of air cooling.
