What is the principle of air cooler?
The principle on which the air-cooler works is as follows- Water, when evaporates it needs heat called ‘latent heat of evaporation’. In the cooler the water that is sprayed over the pads when evaporates takes the required latent heat from the atmospheric air surrounding them which on losing its heat cools down.Click to see full…

In this regard, what is the function of air cooler?The function of an air cooler is similar to that of an evaporator. What makes it different is the type of cooling medium it uses. An air cooler is a heat exchanger used to cool and/or dehumidify the air. Brine (water with glycol) is typically used as a coolant in air coolers or some other secondary coolant can be used.Secondly, does air cooler really work? Air coolers can cover a larger area, actually cool the air, and work noiselessly. In other words, air coolers are effective till the air humidity reaches beyond 50%. Air coolers may be less effective in moderately humid areas, but they can still provide ventilation and air circulation. Keeping this in consideration, what is the principle of desert cooler? Desert Coolers: Desert coolers are based on the simple principle that when unsaturated air comes in contact with water, the water evaporates. In the process, the moisture content of air increases, while its temperature decreases. The resulting cold but moist air is used for providing cooling.Can we use air cooler without water?If there is no water in the Air Cooler, the pad will remain dry and the evaporation will not occur. As a result, the air released from the Air Cooler will be hot air only. To be precise, Air Cooler will work without water as a simple fan only. To get the cool air from the Air Cooler, supply of water is must.
