When it comes to cooling a space, air coolers are an efficient alternative to ACs. They use a natural process called evaporative cooling to cool the atmosphere, and do so without the need for complex components or gases.
They work by absorbing and dispersing heat through the air using water and fans. They are also less expensive to purchase and operate than air conditioners.
An air cooler is a great option for people living in hot, dry environments. The best ones are able to reduce humidity levels as well, so you can breathe clean, healthy air all year round. They can be used in homes, office buildings and industrial spaces. Moreover, they are much safer and more eco-friendly than an air conditioner, as they don’t circulate stale and polluted indoor air.
The most common type of air coolers are evaporative, which works by harnessing the power of evaporation to cool the air temperatures. When water evaporates, it turns into a gas and the high-energy particles leave first, which leads to a drop in temperature. This is why a wet cloth on your head feels good on a hot day — the moisture absorbs and removes the heat from the skin.
Evaporative air coolers are very effective in desert regions, where the air is largely dry. They’re not as effective in humid areas, however, because the water molecules have a hard time separating from the air and releasing their heat. They work best in places where there’s plenty of sunlight, which makes the evaporation process faster.
An evaporative air cooler has a water tank that holds liquid for evaporation and a fan that blows the wet air over a honeycomb filter. The filter is designed to trap pollutants and dust particles, so the cooled air comes out filtered and cleaner. Many air coolers come with trays for adding ice cubes to enhance the cooling effect.
A typical evaporative air cooler has a long ‘air throw’, which is the distance over which the cooled air can be spread in a room. Some brands such as Orient Electric also offer models with AeroFan technology that provides higher air delivery and lower noise.
The cooling performance of an air cooler depends on its water tank capacity and ice storage capability. The higher the capacity, the more cooling it can provide. Air coolers with ice tanks are usually quieter than those without, as they don’t need to run the fan at full speed in order to circulate the ice cold air.
Another factor to consider is the size of the cooling pad, which affects how much cool air it can produce. Larger pads can cool a larger area, but can also be heavy and difficult to transport and install. The right size will depend on the amount of space you have in your room and how often you want to use it.
