Come summer and there emerges a dire need to stay indoors as much as possible to save from the burning heat outside. The sad part is that indoors aren’t much different either. But the good news is that unlike outdoors, our indoors can be made cooler to make them ideal for staying in and enjoying the summer glory.
This is where air coolers come into play – a magical appliance that’s no longer a luxury; it’s an absolute necessity in rising temperatures. For those who aren’t clear about the working of this device and are interested in buying an Air Cooler for the summer, here’s all you ever wanted to know.
How Does An Air Cooler Work?
Air coolers work almost similar to how sweating works for the body. The latter facilitates evaporation of water particles present on the skin’s surface. These particles help throw out heat during evaporation, thereby cooling the skin. An air cooler also makes use of water evaporation to help cool the environment it’s placed in.
When the inlet air blows past the wet cooling pads in the cooler, the water particles present on the cooling pad surface take away some heat with them as they evaporate. This leads to a colder outflow of air through the incorporated fans or blower. However, to keep your air cooler from degrading in cooling capacity, you should ensure that you frequently clean the cooling pads and place it in an aptly ventilated room for it to function effectively.
Types of Air Coolers
Air coolers generally come in various designs to suit different needs. There are two main types of air coolers highly popular in the market to battle the summer heat:
- Desert Air Coolers
- Personal (Room) Air Coolers
Both of these air coolers are used in different climates. While the desert ones help cool dry arid regions, personal coolers are widely preferred in humid areas. Also, desert coolers are generally larger than the personal ones and therefore ideal for large spaces, preferably outdoors such as on the terrace or in the backyard.
Personal air coolers, as the name suggests, are meant for personal use in office or home spaces. They are designed to cool specific small areas of the room. They also consume lesser energy and don’t produce much noise upon operation either, unlike their desert counterparts. We’ve reviewed some models across both types for your reference in our article here: Best Air Coolers in India in 2021.
How To Use Air Cooler Effectively?
Air coolers are an cost-effective, energy-saving, and convenient option as opposed to air conditioners to keep cool when temperatures soar above normal in summer. Yet, a lot of people complain about air coolers not being effective when it gets too hot outside. The fact is that there’s a possibility that coolers aren’t being used properly to utilise their efficiency to the maximum. As a result, they fail to produce the desired effect.
This is how to use air cooler effectively so that you can stay cool within even when it’s sweltering hot outside.
Some Frequently Asked Questions
1. How To Make your Air Cooler Give Out Colder Air?
Here are a few simple steps to follow to ensure that your air cooler gives out the coldest air in the hottest climate:
1. Position it correctly – Where you place your air cooler matters. Try and keep it in a shady area of the house, if possible. If there isn’t one, you may consider building a tent or temporary shade to prevent direct sunlight falling on the cooler.
2. Open a window on the opposite side of where the cooler is positioned. This helps create cross ventilation, making the cooler naturally throw colder breeze.
3. Always keep the cooling pads free of dirt and mold. They reduce the cooler’s efficiency by blocking the air and also lowering the cooling effect. Replace pads regularly.
4. Fill the water to the level indicated. If not properly filled, it may not work to its maximum efficiency.
5. Before you turn on the fan of the cooler, leave the pump on for about 10 minutes first. This will saturate the cooling pads. Then turn on the fan. The cooler will blow cold air instantly instead of gradually with the soaking of the pads.
6. Add some ice to the water in the cooler to increase its cooling. You can put the ice in the water tank into the area specified on the body of the cooler.
2. How To Reduce Air Cooler Noise?
Your air cooler fan may be producing a lot of unwanted sound while operating because of the following reasons:
1. The fan bearings may be worn off and need to be replaced
2. The fan is imbalanced
3. There is dirt or mold deposited on the fan blades or air ducts are blocked
4. The swamp pads need to be changed
5. Screws and bolts need to be tightened
Fixing the above issues can help reduce the noise created by your air cooler fan. Also, maintain your air cooler well. It’s important to get them serviced at least once every season. If the above tips don’t help, ask a technician to look into the matter.
3. Can An Air Cooler Work Without Water?
All air coolers work on a basic principle – they cool the air in the environment by evaporating the water present inside. To be able to use an air cooler, it needs to be filled with the appropriate amount of water. This explains that it’s difficult to operate air coolers without water at all. In fact, filling the cooler at water levels lower than indicated may even damage its pump.
4. How To Fill Water In Air Cooler?
You can easily fill water in the cooler tank with a water hose in case the cooler is positioned outside the house. If placed inside a room, you may use a water mug/jug to fill water through the small opening at the bottom of the cooling pads. Make sure to fill the water tank up to the level indicated on the cooler. Replace the water in the cooler every fortnight for higher efficiency.
The type of air cooler you choose definitely depends on your personal need, space availability, and of course, budget. Regardless of the type of cooler you choose, you can always make it work more efficiently by following the tips detailed in the sections above. Lead a cooler summer, sit back, and relax.
