What is Evaporative Cooling?Evaporative cooling is quite simply, cooling with water. By evaporating water, the temperature of the air in contact with the liquid water will lower. This is the same sensation that is felt when climbing out of a swimming pool, when your body sweats, or even when a breeze blows across a lake.When water evaporates, a state change occurs (the state of water changes from a liquid to a gas). In order for this change to occur, energy is needed. This reaction is an endothermic reaction, meaning that energy is actually absorbed, as opposed to being released. The energy needed to change the liquid water to a gas is taken from the heat in the air in contact with the liquid water. During this reaction the liquid water changes to a gas and the temperature of the air lowers. In short, by pulling air across water, the temperature of the air will lower. Evaporative cooling is a technology that has been used for milenia to cool living areas. Archaeologist have found proof of evaporative cooling mechanisms in ancient Egyptian culture and is still a predominant form of cooling in arid climates world wide.  Related FAQs Listing : |
