the water is taken from the air in the form of sensible heat, which affects thetemperature of the airMany of us use air coolers to battle the summer heat. They are both, cost effective and also provide a lot of comfort. However the rising temperatures every year means we need to use aircoolers more efficiently.An air cooler will first pull natural (warm) air from outside using a fan and then pass it throughwet cooling pads. A pump sprinkles water on top of the cooling pads and allows it to trickledown through them. As the water evaporates, the temperature of the air drops and the fan blowsout a current of fresh, cool air.Circulating cool air throughout your home is especially important during thehot summer months. Experts recommend an indoor temperature of 78°F (during the day) to keepcosts low, but still maintain comfort, energy efficiency, and indoor air quality. Heat can affectthe body in uncomfortable ways.Air cooler is commonly defined as rejecting heat from an object by flowing air over the surfaceof the object, through means of convection. Air cooling requires that the air must be cooler thanthe object or surface from which it is expected to remove heat.India is a tropical country in which most of the regions experiences very low temperature duringthe winter and very high temperature during summer seasons. That is the temperature range between summer and winter season is very large. Hence it is not a very pleasant experience andhighly uncomfortable. Through cheaper method of heating are available during the winterseason, method of cooling down the hot temperature during the summer do not have wide varietyof options. Air conditioning has high initial and running cost, which cannot be afforded by all the people in a developing country like India. Air cooler are relatively cheap, but provideunsatisfactory results; there is a need for developing a cheaper room cooling system.Conventional air cooler is one of the major contributors of CFCs into the atmosphere. Analternative type of cooling, which does not expel CFCs is highly desirable as one important stepin the correction of this problem. So this is why adiabatic cooling is environmentally friendly because it is a passive cooling method that does not expel CFCs. It is 100% fresh air coolingwhich even help to clean the air it cools. With the help of evaporative technology swampscoolers provides cooling at cheaper than central air or large air conditioner
