Best Air Coolers in India 2019- Buyer’s Guide
How do air coolers work?
Air coolers also known as desert coolers work on the principle of evaporation. When water gets heated it becomes water vapor. In these air coolers, hot air from outside is passed over cool water. The cool water absorbs the heat of the air and evaporates. The transfer of heat from the air to the water – causes the air temperature to drop. This makes the air inside cool.
The fan inside the machine then circulates this cool air around your room. This process gets repeated again and again – making the room cool. This is the basic working of an air cooler.
Now, we are not patient! On a hot sunny day – we want the room to be as cold as possible and as fast as possible. So, air coolers now come with cooling pads. The hot air passes through the cooling pads. The water evaporation takes place within these cooling pads. A pump is used to make sure water keeps flowing through these pads. The room temperature drops about 5 to 6 degrees with use of an air cooler.
Air coolers work best in hot and dry places like Rajasthan, whole of North India, Madhya Pradesh, Gujarat and Maharashtra. In humid places like Chennai, and Guwahati desert air coolers don’t work properly. Some brands have launched air coolers with humidity control. Such coolers can control humidity to a good extend.
Advantages of Air coolers
- Air coolers are cheaper than ACs. They can help you save a lot of money. If you run an AC for 10 to 15 hours a day for 30 days – it will cost you about Rs 3000 to Rs 4000. You can get a good air cooler below Rs 10,000. Your air cooler will pay for itself in a couple of months.
- Power saving air coolers use very little electricity which will reduce monthly bills.
- Best energy efficient air coolers in India are now available at affordable prices. They are very environment friendly. Unlike ACs, coolers don’t emit CFCs and other harmful gases. They are an eco friendly choice and don’t add to the growing problem of global warming.
- You don’t need to spend money to install or service them like ACs.
- They are portable so you can shift them around the house as per your need.
- Air coolers work best if you live in a hot and dry place.
Things to consider before buying an air cooler
#1. Size of your room and size of cooler:
Size of the cooler is the most important thing to consider. If you buy a very small air cooler and your room size is big – it will take lot of time to cool the room. It will not be effective, and you will get frustrated.
So, first check your room size. If you’re living in an apartment then most rooms are usually 1010 (100 sqft), 1212 (124 sqft), or 12*14 (168 sqft). To roughly calculate walk the length of the room. Count the number of steps you took. Do the same for the breath.
You get approx sq ft area of your room.
#2. Effectiveness of air coolers in Indian climatic conditions.
An empty glass of water – can hold only a fixed amount of water. If you keep adding more, what is going to happen? It is going to overflow. It will not be able to hold that water. Similarly, air also has limited capacity. It can also hold only a limited amount of water.
Humidity measures how much water is already there in the air. If the air is hot and dry – then the water evaporates and goes into the air. If the air is hot and moist – where is the water going to go? If the air already has enough water, then where will the water from your air cooler go? Nowhere.
Your air cooler will not be able to work properly in humid climatic conditions. Places like Chennai, and Guwahati where the air is sticky – can only use air conditioners. Air coolers work best in hot and dry climates like that of North India, Bihar, Madhya Pradesh, Gujarat, Maharastra, Rajasthan etc
Make the Decision:
Write down the size of your room along with your budget.
Now, that this is clear – we can see different features and benefits of air coolers.
What to look for in an Air Cooler
#1. Cooling Pads
Cooling pads are the material on the side of the cooler panels. They absorb the water and help it to evaporate faster. There are two kinds of cooling pads:
Aspen/Wood Wool/Bhusa: These are the old kinds of cooling pads where the material used is wood shavings. They are 75% efficient.
Honeycomb Pads: Here the pattern is in shape of honeycomb. They are quite thick and effective. They absorb water better and allow cooling water faster. They are 85% efficient. Go for coolers that have honeycomb pads at least 90mm thick.
#2. Ice Cube Trays:
To ensure more cool air, new models of air coolers now come with ice cube trays. Ice water goes into the tank with the melting of ice and evaporates faster.
#3. Water Tank Capacity
If your air cooler has large water tank, it will run for long time. Go for a large capacity air cooler, which you will have to fill only once or twice in a day. Anywhere between 30 to 50 liters is sufficient.
Make the Decision: Decide how big a tank you need. In a 30 liters tank you will have to fill water twice a day. In a 50 liters tank, only once a day will be good enough.
#4. Water Level Controller and Indicator
Air coolers now come with automated water level controllers. They are able to maintain the amount of water within the air cooler. Water level indicators lets you know how much water is left in the water cooler. It makes life easier, as you don’t have to keep opening the cooler to check water level.
#5. Empty Tank Alarm
Empty tank alarm will let you know when water is at less level, so that you can refill. This also helps to prevent damage.
#6. Timers and Speed Controlling Knob
Timer helps you save power as well as the energy. You can pre set the time when you want the air cooler to shut down at night. Speed control knobs of High, Medium, Low let you control the temperature and speed of fan.
#7. Remote Control
Nowadays, just like ACs, even air coolers come with remotes. You can control speed settings etc without getting up from the bed.
Make the Decision: Do you have the budget to spend for more comfort? Then go for a remote controlled one. A non touch, without remote control simple air cooler can save you around Rs 3000 to 4000.
#8. Coolers that work on Inverters
Power cuts happen a lot in India. Compatibility of air coolers with inverters can be a huge benefit. It is now available on almost all good brands of air coolers. Air coolers consume about 120 watts to 180 watts of electricity only. They can run on inverters unlike ACs. If you already have a 600VA above power of inverter then you can use an air cooler with it.
#9. Humidity Control
As already explained, air coolers can only control humidity to a certain. You will only need this feature after June/July when monsoon begins. From March to June you can use the air cooler without any humidity control.
Some good brands of air coolers have come up with humidity control.
