How does an air cooler work?

Air cooler

Air coolers, also know as evaporative air coolers are often mistaken as air-con units. However, while they have some similarities, the concept on how they operate and the end result is fairly different.

Air cooler draw its function from nature, just like a sea breeze which lowers the temperature of the air. Air con units on the other hand, uses refrigerant and requires a hot air output to rapidly cool the air down and reduce the humidity of the air.

Components of an air cooler

Air coolers are often mistaken as air conditioned units due to the large bulky size. Air coolers contain a fewer components than your traditional air-con unit: Air filter, cooling media, water pump, water tank and the fan unit.

How does it work?

It all begins with the water tank and the water pump. The water pump pulls the water out of tank and runs the water through the cooling pad/ media which is usually of a honeycomb structure. At the same time, warm air is sucked from the bad and through the media/cooling pads, thus cooling the air with the lower temperature water. It is then recirculated through the system and the main fan output the cool air in the direction of the fan. This process requires water as the key ingredient and there will be a need to top up the water every now and then.

Intended use

Air coolers are great for indoors and outdoor settings. Because our air coolers are industrial size, they can provide adequate cooling to large areas while consuming significantly lesser energy when compared to air con units. They also have lesser parts and do not need to provide an outlet for hot air.

Can air coolers work without water supply?

Air coolers can still operate without any water supply. However, because the water is used to lower the temperature of the air, all you will be renting is a large fan. For the optimal performance, it is important to fill up the tank with water before operating.
