Buying Guide for Air Coolers
Before making a purchase, it is important to understand the specifications and other information related to the appliance. We have detail information below that helps to take right decision.
How does an Air Cooler work?
Air coolers use evaporation method for providing cool air. For this, continuously water supply is necessary. They contain a reservoir where water is stored. Using a pump, water will be dispersed from reservoir to cooling pad. Outside air is drawn into the cooler and is further guided through the cooling pad.
The water or moisture present on the cooling pad absorbs the heat and evaporates. Once the heat is transferred, temperature of the air decreases. Now cool air is dispersed outside using the fan. The continuous process of drawing hot air and dispersing cool main – will bring down the temperature of the room.
Types of air coolers:
Three different types of air coolers are available – tower, room and desert. Though their working principle is same, few variations like water capacity differentiate them from one another.
|Room Air Coolers||Dessert Air Coolers|
|20-30 liters is the water tank capacity||30- 60 liters is the water tank capacity|
|Small to medium sized room can be cooled||Larger sized rooms can be cooled|
|These coolers are suitable for humid weather conditions||These coolers are suitable for dry areas|
|Blowers are mostly used in this coolers for cooling||Fans are used for cooling|
Room/Tower Air Coolers:
Areas with humid conditions is where these personal or room coolers are mostly preferred. Instead of normal fans these air coolers comes with the blower and is suitable for smaller rooms, price is lesser.
Personal cooler allows easy mobility as it is smaller in size it can be placed anywhere like kitchen, dining, bedroom etc and can be carried everywhere easily as it comes with caster wheels.
It has 20 to 30 liter water capacity; it uses low electric power than desert cooler which makes it more apt for household use.
Desert Air Coolers:
These air coolers are mostly suitable for dry area. They are designed for cooling large rooms and compared to personal coolers these are bigger. Cost is also little high compared to personal coolers.
Water capacity of these coolers is 30 to 70 liters; they are designed with fan to blow air more effectively. To draw the air from outside desert coolers should be mounted on your window. You will be able to move it from one room to other and is suitable for halls, restaurants, office, and hotel use.
Than a normal cooler desert cooler uses more energy, you can opt this cooler if you prefer excessive cooling.
If you need a cooling unit that is helpful to fight extreme heat then dessert coolers is the best option. If the room is smaller than room coolers would be enough.
Factors to Consider While Purchasing an Air Cooler:
Detail information of each factor is mentioned below. With the help of this information, you can choose the right model that suits your requirements.
1. Water Tank Capacity
Air cooler with bigger tank size provides cool air for longer time and requires re-fills less frequently. You should select a model according to your requirements. The tank size is relative to the real size of the unit so the size should be enough big to store enough water and fulfill the space of the storage.
- Tower Air Coolers – 15 to 30 Liters
- Room Air Coolers – 20 to 50 Liters
- Desert Air Coolers – 60 to 100 Liters
2. Cooling capacity Or Air Delivery
According to the size of the room you want to cool there should be the correct size of the cooler for it to work effectively. You need to have clear idea of the measurements of the room and the area should be more than the room size or else equal to it.
In the description or on the label of the cooler it will be clearly mentioned about the cooling area. You will find this under the heading “cooling area” or “area covered”.
CFM (cubic feet per minute) this the terms in which the air flow of the air cooler is measured. The CMF refer to the amount of air cycled in your room every minute. By calculating the CMF that is required for your room the correct size of the air cooler is calculated. The higher the CMF, the fan moves more air in the room.
To find the right size of the cooler you need there is the simple calculation which will help you out.(The denominator factor 2 is denoted as the air in the room gets changed once in every 2 minutes.)
Example: ceiling is 8 feet high and the room size is 100 sq feet in area then,
Air displacement or Air delivery (CFM) = 100 x 8/2 = 400 Cubic feet/ min
Many leading brands at present state the sir displacement in cubic meters/ hour.
Convert the CMF to cubic meters/ hour multiplies CMF value by factor of 1.699.In the example given size of the required cooler is 400CMF that is equivalent to
1.699 x 400 = 680 cubic meters/ hour (approx).
Having the correct size cooler is very important, it will take long time to cool if the cooler size is smaller and depending on difference in wattage it may consume more energy of the small and right sized cooler.
3. Cooling pads
Cooling pads have direct impact on the cooling efficiency of an air cooler. Once get wet due to water dispersal, they absorb the heat from passing air and cools it. For better outflow of cool air, you should prefer thicker cooling pad. Two types of cooling pads are used – honey comb and wood wool.
Honey Comb cooling pad – as the name implies, these pads are structured in honey comb design. They are durable, efficient and require less maintenance. They are a bit expensive compared to their counter-type.
Wood Wool Cooling Pad – It is made up of thin synthetic fibers of wood. They usually look similar to grass. They are less efficient, durable and require high maintenance. But they are very reasonable.
4. Air Cooler Size
If you are lying on the bed and the cooler does not reach above your bed level is completely of no use, so buying a cooler that is adequate in height that throws air to your body level is important. You need to select the cooler that fits perfectly to your space.
Box shaped design and tall tower design are the sizes that air cooler comes. For box size coolers you can buy a separate stand with different heights.
5. Power Consumption
Before you buy the cooler check the power usage, the lower the watts mentioned the lesser the power it will consume. Anything between 160w to 220w is good. On the product description and sides of the cooler you can check the power usage.
6. Castor Wheels
It’s better to get an air cooler with castor wheels if you plan to use it in different rooms. A Castor wheel helps you to move the cooler around the house. Some come with attachable wheel option.
Castor wheels come with different types. Few come up with plastic which done last in long run as they lose the efficiency. Cooler with heavy duty castor is the best option. These are made up of thick rubber and strong metal material that suits best for long run and makes easy for you as you can push across the rooms more often.
7. Water Level Indicator
This feature indicates the water level present in the air cooler. It helps the user identify when the water runs out or is about to run out in the unit. In some air coolers, this feature is available in manual option. While filling the water tank, you can utilize the same to make sure you don’t over-fill it.
8. Variable Speed Control Knob
Low, medium, and high are the three evaporative coolers come with. According to the intensity of breeze that you want, you can select the fan power, but the higher speed will be noisier.
9. Empty Tank Alarm
Air cooler requires at least basic water level to stay operational. This alarm will indicate the user by making beep noise that water levels have decreased to basic level. This helps the user to re-fill the water tank before it completely runs out of water. If the water levels are not refilled in time or if air works without water, then motor can get damaged. This feature is present only in high-end models.
10. Pad Thickness
Water absorbed by the cooling pad has direct impact on air cooling. So, basic thumb rule to consider while analyzing this feature is – thicker the pad, cooler will be air production. Ideal thickness level is considered as 90 mm.
Most of the people don’t prefer to buy air cooler as they take up lot of space and do not go with the aesthetics of the room. Manufacturers now-a-days are providing sleek and stylish design models like tower air coolers. These air coolers are in trend as they are powerful to be used in large rooms and take up less space. Tower model blow air at certain height and two directions so it has to be placed to the corner of room. It is little expensive and not widely used in houses.
12. Remote Control Feature
Choose the air cooler that have remote, so that it will be easy for you to access the cooler easily. You don’t need to get up every time to change the speed settings; if you have remote system you can control the speed of fan easily.
13. Ice Cube Tray
Few coolers come with the facility of ice tray. You can keep the ice tray on the top shelf of the cooler, as the ice melts it mixes with the water tank and helps in cooling the temperature of water in few degrees.
14. Shutoff dampeners
Coolers are designed in the way that when they release cool air they ensure that coolness does not lash out of the cooler premise. Flaps or shut off dampers present at the discharge of fans preserve the cooling effect of air that comes from cooler.
Flaps are put along the duct, when the cooler is switched on they automatically open and closes when cooler is switched off.
15. Air Cooler Compatible with an Inverter
Air coolers are well known for low energy consumption. Some coolers have added features that can even work on inverters. Compared to standard air coolers these coolers consume up to 50% lesser power. If there is constant power cut at your home then this is the best option.
It is always good to choose a well known brand than local made and also check out the warranty. The well known brand always gives you good service, assist you better and they will come to house and fix it.
Air coolers that are listed here are all well recognized brands, you can make a purchase without any worry.
Checking a budget is also important before you buy the cooler. In India the best air coolers from the well recognized brands cost starts from Rs 5000 to Rs 12,000 and above. You need to pay little more if you want to buy a cooler with high tank capacity.
As of my choice, I would like to suggest anything around 30 to 50 liters of air coolers would be great, between Rs 6000- Rs 9000 you will get this type of air coolers.
Manufactures provide a year warranty generally as few other manufacturers may provide a longer period of warranty. Choose the model that have longer period, so you will be having protected and safeguarded after your purchase.
19. Effectiveness of Coolers in various temperatures
In the hot and dry climates air coolers works well. Depending on the evaporation of the water in atmosphere, the working of the air cooler depends. If the water evaporates more, you will get the cooler air.
For the air holding capacity of the atmosphere there will be a limit, if there is humidity already it will not be able to hold more water and give good result in getting cool air. It will be cooler in drier climates. Thus, Higher the humidity lesser will be the effect of cooler.
‘Humidity Control’ is the new addition to the coolers this overcomes the drawbacks. Many top brands like Bajaj, symphony models have this special feature and can be used in humid coastal region.
The figure shows relation between temperature that is outside and humidity in air.
If the air temperature is 90 Fahrenheit (32.3 Celsius) and humidity is 30% then outside air get cool up to 74 Fahrenheit (23.3 Celsius).
The temperature that comes from cooler also increases as the humidity go on increasing.
Advantages of Air Coolers
- When compared to air conditioners, air coolers cost 70% much lesser.
- Air cooler consumes 80% less electricity than air conditioner and 30% more power than a ceiling fan.
- As they use water for cooling the air and don’t consume more power, air coolers are considered to be eco-friendly.
- Being portable, you can move air coolers from one to another.
- Air conditioners take inside air, cool it down and direct it into the room again. But air cooler takes fresh air from outside, cool it and direct it inside the room. So, fresh air is circulated within the room.
Disadvantages of Air Coolers
- One of the main drawback of using an air cooler is that they are dependent on climate. In high humid areas, coolers are inefficient. Air coming out from air cooler will be humid due to evaporated water. So, coolers add more humidity levels to the air. If you live in coastal or high humidity areas, then check out the humidity control option beforehand.
- Coolers require continuous water supply for providing cool air. If you live in a locality with water scarcity, then coolers may not suitable.
- If you live in an area with hard water supply, then internal parts of the cooler are more prone to corrosion.
- Noise generated by fan can be frustrating.
Tips for better working of Air Coolers:
The tips of the better working air coolers are,
- The position of the air cooler should be in front of window. The evaporation will be faster, if the air is hotter. From the fan the cooler air is blown.
- The humidity needs to be pushed out to create the good ventilation in room. Due to this window of the room should be open. As it results in increasing the room temperature you should be careful that the window should not be opened too wide.
- Using ice water is good on very hot days as it will lower the temperature further.
- It is time to clean the cooler if there is foul smell, cleaning and maintaining will increase its lifetime.
- Keep cooling pads of cooler clean all time for good performance.
- Be sure there are no leakages and it is important to maintain the water tank clean.
- Cleaning of the fan blades will make sure that the air cooler will be of highest efficiency.
Effectiveness of Coolers in Various Temperatures
Air coolers are best suitable for dry and hot areas. As its main working depends on water – more the evaporation, cooler the air will be.
However, air has certain limit for holding moisture. If the air is already humid, then it will not hold more water. So, evaporation and cooling doesn’t happen to the extent which usually occurs in dry climates. So, higher humidity, less will be the cooling.
To solve this issues, manufacturers have been including humidity control feature in few of their air coolers. Bajaj and Symphony brands provide this feature in some of their models. If you live in humid areas, then choose an air cooler with this option.
To provide better insight, we have provided a clear diagram representing the relation between humidity and temperatures.
If the humidity levels of your area is 30% and temperature is 32.3 Celsius (90 F), then air can be cooled up to 23.3 Celsius (74 F). As the humidity levels increase, efficiency of cooling also decreases.
Air cooler Vs Air conditioner:
The comparison between air cooler and air conditioner are given in below table.
|Air Cooler||Air Conditioner|
|Air coolers prices start from Rs 3000 to Rs 15000.||Air conditioner cost between Rs 25,000 to Rs 50, 000.|
