Air coolers are box-like units that contain a fan, pump, and water-soaked pads. The cooler needs to fit with the appropriate amount of water when needed. When you switch on the air cooler, the hot air in the surrounding circulated by the cooler and sent through the water-cooled pads, it lowers the air temperature.

Air coolers work based on the evaporation process. Instead of using chemicals to cool the space, air coolers use fresh air and water.

The way sweating cools your body; the air coolers cool the room in the same way. Water vapor is introduced into the air to raises humidity and lowers the temperature. It is a very ancient method of cooling.

The summers are scorching in India, and almost everyone looks for ways to cool down. A regular fan is not able to beat the scorching heat of the summers. So you decide to opt for more heavy-duty equipment. You look out for two options: Air Cooler and Air Conditioner. Suddenly you are confused. So what is the difference between an air cooler and an air conditioner? Below mentioned are the difference between an Air Cooler and Air Conditioner:

The cost of an air conditioner is more as compared to the air coolers.
The air conditioner’s indoor air quality is re-circulated by the direct air, whereas indoor air quality by air cooler is fresh and filtered cold air.
The cooling agents used by the air conditioner are refrigerants or coolants, whereas the cooling agent used by air cooler is water.
The maintenance of the air conditioner is complex, whereas maintenance of air cooler is much accessible.
An air conditioner can only be used for indoor purposes, whereas air cooler can be used both indoor and outdoor.
High carbons emissions are done by the air conditioner, which is not suitable for a person’s health, whereas air coolers are environment friendly.

Features

A person needs to buy the right air cooler that is best for the person’s home is certainly going to make their summers much more comfortable. There are many options to choose from, but you should always choose what best suits your requirement. Technology is continuously changing from the past few years. Still, the main thing is that the essential workings have remained the same; the components of air cooler have seen an upgrade in terms of quality and performance, ultimately benefiting the person. That is why the person needs to look for these critical features when getting a new air cooler.

Indoor Air Cooler or Outdoor Air Cooler

In simple terms, an indoor air cooler is a compact version of the old/traditional air cooler and often comes with caster wheels, which make it easier for the person to move them. Most of the indoor air coolers have a smaller water tank to prevent them from being overly heavy to move. An indoor air cooler is ideal for those people who have little to mid-size rooms.

Outdoor air coolers are often called desert coolers and are more extensive, and they may require a stand or mount for their placement. Traditionally, all the outdoor air coolers were fixed units, but modern designs from most of the brands added more portability features to most of the devices. Outdoor coolers have huge tanks than the middle and compact size coolers.

Cooling Pad Technology

It is an essential part of air coolers, which has received a significant upgrade in modern air coolers. Air coolers used in the earlier times use cooling pads or cooling media that are made from wood shavings and synthetic fibers. Those cooling pads of the previous times have lower water retention capabilities and also need higher maintenance. These aspen wood cooling pads that are now used are also quite fragile and susceptible to damage during the installation of air coolers. The cooling pads are available easily are also quite cheap.

Most of the modern air coolers use Honeycomb design cooling pads that are made from cellulose material. Stylish cooling pads have higher water retention capability, which in turn increases the cooling efficiency of the air cooler and cools the room much faster. The honeycomb design is also more durable, and it does not require frequent replacements than aspen wood cooling pads. The price is more but makes up for the price difference with their long service life.

Copper Fan Motor

Copper is one of the efficient conductors of electricity, and hence it offers longer life and low power consumption. When a person is buying a new air cooler, it is better to opt for the one which has a copper made by a fan and pump internals. It will automatically lead to reductions in the electricity bill of the person.

Ice Cube Tray

A new feature is introduced with the portable, indoor air coolers; it allows the person to add icy water to the tank for the quicker cooling of the room. However, if a person adds too much ice can, it can prevent the evaporation from occurring and reduce the cooling. So, one should use this feature as per directions in the instruction manual or product demo.

Inverter Compatibility

Air coolers indeed consume way less power than air conditioners, so most of them can be used with inverters. However, not all of the air coolers will perform on inverters. So those air coolers are made locally are not as efficient as modern air coolers with the copper wiring and internals. Typically, one can run a branded, inverter compatible air cooler as it will ultimately benefit the person. an inverter is more than enough to run these air coolers.

Water Level Indicator

There is one convenient feature that will allow a person to know about the tank’s water level without having to peep around through the cooling media and fan grill.

Tower Design

The design of the air cooler is a sub-type of the indoor air cooler. If a person lives in an urban home with a limited carpet area, they must consider these air coolers to save space and increase portability.

Remote Control and Digital Features

Lastly, most of the modern air coolers come with feature like AC-like remote functions and digital control panels that offer convenience to the person and has better fan-speed control. 

Benefits of Air Cooler

Effectiveness of Coolers in Various Temperatures

Air coolers are the one that works the best in hot and dry climates. The working of the air coolers depends upon the process of evaporation of water into the atmosphere, if more water evaporates, then the air will be more cooling. Then the air cooler will not be able to hold more water, so the air will not cool to the extent that it would cool in drier climates.

Hence higher the level of humidity, then lesser will be the effect of the air coolers. Nowadays, most of the manufacturers are trying to make those air coolers with a feature called ‘Humidity Control’ to overcome this drawback. Many of the leading brands of air coolers such as Bajaj and Symphony manufacture models that are having special features for controlling the humidity, and it can be used in humid coastal regions as well.

Apart from the climatic conditions, even the cooling pads can be used to contribute to efficiency. Different cooling pads used for different coolers’ have a significant effect on water absorption and the evaporation process. The two popular designs used are the honeycomb and the aspen (wood wool).

There is much difference in both patterns: the capacity to absorb water and facilitate the passage of air through it. It can be said that Aspen pads are approximately 75% efficient in contrast to honeycomb pads that are about 85% efficient. 

Power consumption

Air coolers consume less power when compared to air conditioners. A 1-ton AC would approximately consume 0.8 units in an hour, whereas an air cooler that is of the equivalent size of room would only consume an approximate of 0.1 units in an hour. Similarly, if we consider a 1.5-ton AC would consume about 1.2-1.3 units in an hour, the air cooler is equivalent to the size of the room would only consume an approximate of 0.12 units in an hour.

Higher the consumption of energy, then it will lead to higher electricity bills. Hence along with being eco-friendly, air coolers are also pocket friendly for the people! The power consumed by most air coolers is much less than that of the air conditioners, so the savings in electricity for an individual is very much significant. The low cost of coolers is good at saving lots of power, which is an excellent option to opt for the buyer. 

Material Used

Another factor that is to be considered is the material that is used to make the air cooler. The air coolers with fiber body look more elegant than their steel body counterparts, but they have smaller cooling pad areas. Therefore, fiber coolers have lesser cooling efficiency when compared to the steel body coolers. Galvanized steel body offers the protection to air coolers against rusting, and hence it will give longer life to the air coolers along with that too with increased efficiency.

Climatic Condition

Know the Essential Factors to Find the Right Cooler

Choose the right Capacity and Room Size

One should choose the air cooler according to their room size, or else it will create a problem for them. It is imperative to have a cooler of the right size if the cooler is smaller than the required size, it will have to work for a longer time to cool the room so it may consume more energy depending on the difference in wattage of the small and right-sized coolers.

If the cooler’s capacity is below 15 L and room size is up to 100 sq. Ft, it is suitable for kids’ rooms or other small areas of the person’s house or office. Air delivery is up to 650 cubic meters/ hour.
If the capacity of the air cooler is 11L-30L and room size is up to 300 sq.ft, then it is ideal for cooling small to medium-sized rooms. It is suitable for spaces like the study room, office cabins, and other small rooms.
If the air more cooling capacity is 31-50 L and room size is up to 300-500 sq.ft, then it is ideal for cooling master bedrooms and other large spaces like office areas.
If the capacity of an air cooler is beyond 50 L and room size is beyond 500 sq.ft, then it is ideal for extremely spacious areas like halls, office canteens, boardrooms, and other large rooms.

Support after-sale

One of the critical aspects of purchasing any of the products is their after-sale service, which means the services that are offered by the company after the sale of the product. After-sale services are much more critical then pre-sale services. If the company does not provide after-sale service, then the product is of no use as sometimes it will not work properly or any of the problems can occur, then it is of no use. Nowadays, every of the air more cooling manufacturers offers after-sale services that are a good thing.

Effectiveness of Coolers in Various Temperatures

One especially makes air coolers for the dry weather. In humid conditions, air coolers are not suitable as they won’t be able to cool the place. The air cooler is fixed with wet cooling pads to cool down the place. As a result, the air will not be cooled to the extent of the humid climate as it would cool in drier climates. Hence higher the level of humidity, then lesser will be the effect of the air coolers.

Power consumption, efficiency, and other factors

Air coolers are good at consuming lower power when compared to air conditioners. Higher the use of energy, then it will lead to higher electricity bills. Hence along with being eco-friendly, air coolers are also pocket friendly for the people! The power consumed by most air coolers is much less than that of the air conditioners, so the person’s annual energy saving is significant. So along with lower investment, the cost of using coolers is less than using ACs that are much good for the person.

Conclusion

The main principle on which air cooler works is evaporative cooling. 

A pump sprinkles water on top of the cooling pads and allows it to trickle down through them. The air coolers work on a straightforward basis. The cooler grabs the hot natural air, and pass the fresh cooling air through the wet cooling pads. The temperature of the airdrops and the fan blows out a current of fresh, cold air. There are three varieties of air coolers that are available: room air coolers (for moderate-sized rooms), personal air coolers (for small or specific areas), and desert air coolers (for large rooms).

There a person has it, a brief buying guide that will help them select the right air cooler for their home.
