Key Facts about Biocooling

Key facts about BIOCOOLING (evaporative cooling) Evaporative cooling is not a new idea. In fact, it's as old as nature itself. Did you ever wonder why you feel cooler by an ocean or river? It's because of natural evaporation. A sea breeze feels cooler because hot air is blown over the water causing some of the water to evaporate and absorb heat. The air becomes a refreshing breeze by the natural process of the water cooling. For many thousands of years, a passive form of man-made evaporative cooling has been used. Thought to have been developed in Persia (Iran), badgirs (Farsi) or barjeels (Arabic) are ducts that catch wind and funnel it past water, usually in the form of a pond and water fountain at the base of the duct, into a building. As the hot air passes the water it is cooled by evaporation. Ingeniously, many of these buildings also have courtyards containing plentiful water so that if the wind is not blowing, the natural action of rising hot air evaporates water from the courtyard, circulates the cool air through the building and exhausts through the tower. Of course, many other steps to control temperature were taken during construction of ancient buildings, such as having high ceilings and very thick walls. Because that's not easy to achieve with today's construction methods -not to mention today's space and cost constraints- heat transfer is considerably higher and passive cooling methods don't provide the benefit required. Therefore, Seeley's leading-edge range of products have simply taken the natural evaporative cooling process and developed it with state-of-the-art technology to suit today's lifestyle.
