Air Cooler type based on cooling process

Direct Evaporative Cooling

These are the cheapest, easiest to maintain and most popular type of Air Coolers in India. You can find variations of these, depending on the area you live in, what material they use to build it. They simply lower the temperature by evaporation of water.

Indirect Evaporative Cooling

This, a relatively more uncommon type, uses a heat exchanger for cooling. The heat exchanger takes the air from the room, cools it then re-circulates it back to the room.

As the internal air never even touches outside air. So, your room is very much protected from external contaminants, germs and pollutants.

Two-Stage Evaporative Cooling

In this type as the name suggests, cooling is done in two steps. In the first step, the air is cooled within the cooler, in the second step, water vapors are separated.

This type of air cooling is best for a humid climate, as it controls humidity and keeps room relatively less humid, as compared to Direct Evaporative Cooling.

 Cooling Pads for Air Coolers in India

See, how Air coolers work are, they use the fan to pass hot air from outside the cooler, through wet pads, which cool the air. But there are a variety of cooling pads available in the market, which can be chosen as per requirement, budget and preference so as to get the best air cooler for you.

  1. Honeycomb Cooling Pads: As the name goes, on looking close, their weaving looks like the honeycomb pattern. They are made up of cellulose, which makes it somewhat expensive. But that cost is made up by its long life and efficiency.
  2. Aspen Wood wool Cooling Pad: This resembles wood shavings or saw shavings, and is very cheap. But these are easily deteriorated and hence need high care.

Advantages and Disadvantages of Air Coolers

Even after decades of introduction of advanced and better cooling technologies and Air Conditioning, Air Coolers are still widely popular. Let’s see why.

Advantages  of Air Coolers

  • Indian society consisting of mainly middle-class families, affordability and budget are huge deciding factors. Air coolers are multi-fold cheaper than air-conditioners and this is the biggest air cooler pros. Where a decent Air conditioner would cost around 25000 to 30000 Rupees, a good quality Air cooler can be bought fewer than 8000 Rupees.
  • Apart from low starting cost, operating cost for Air coolers are low too, as compared to other cooling technologies. Air cooler motors aren’t very demanding on electricity, keeping your electricity bill low. For a rough idea, two to three Air Coolers can be easily operated under the operating of one Air Conditioner. Energy efficiency of air cooler increases with is BEE star rating.
  • Super low maintenance- Air coolers are hassle-free. Simple. If you buy a metal Air cooler, you paint it and forget it for years. Motors and pumps are covered under respective warranties and aren’t very expensive anyway. All you need is water and electricity and you will have easy, efficient and effective air cooling for years on end.
  • They can cool large spaces very easily and don’t use much power in the process. Large halls, auditoriums and arenas are cooled using Desert Coolers.
  • They do not use compressor gases for cooling. In most Air conditioners, until a few years back, Chloro-Fluoro Carbons were used as coolant fluid. These Chloro-Fluoro Carbons travel up in the atmosphere and react with the Ozone layer. The Ozone layer is that layer of our atmosphere which filters out cancer-causing Ultra Violet rays. So Air coolers are Eco-Friendly too.
  • Most air coolers are foldable or have easy setup and are light. This makes them quite portable.
  • Since Air coolers are light loads on electricity, they can be plugged right into any normal socket, unlike Air conditioners, which require high load switchgear installed for safe operations.

 

Like any other thing in life, Air Coolers come with some disadvantages too.

Disadvantages of Air Coolers

  • Being dependent on water for cooling, availability of expandable water is a necessity. In abundance.
  • Air cooler uses water vapors for cooling, which can be a problem in already humid places.
  • No climate control like Air conditioners.
  • Modern Air Conditioners come with Air Filters with filter out germs, dust and pollutants, which Air Coolers lack.
  • Noise levels are high. So it’s an inconvenience in places where a quiet environment is necessary.
  • They need open ventilation for effective cooling.
  • Size of air cooler can be a problem for small rooms.
