Myth :- Air coolers working fine in Chennai Truth :- It's NOT... Lets see about Air cooler operating principle Air cooler / Evaporative cooler, sometimes referred to as a swamp cooler, utilizes water-soaked pads to cool the air. This process works because a fan pulls hot air into the unit, sending it through a series of pads that helps evaporate the liquid into a gas which then blows out cooler than it was when it entered the unit. The evaporation process works similar to the effect of rubbing cold water on your skin on a hot day While air conditioners (AC) draw moisture out of the air, swamp coolers cool with the opposite effect by adding humidity to the air it blows out . The fan also continuously circulates air, creating a slight breeze, which will help make your body feel cooler Now let see the important terms in simple wordings HUMIDITY Humidity in simple term, it is measure of water content in the air. If the humidity is 40%, then 60% water it can still Hold
