Passive Evaporative Cooling Tower

Cooling towers the cooling tower may be used to evaporate precool ventilation air for one or more air handling units ahu reducing the load on the mechanical cooling system.

Passive evaporative cooling tower.

Evaporative cooling is the most economical concept for cooling of a building. Evaporating water is what creates the cooling and makes evaporative coolers and wind towers work. Analysis and evaluation of a passive evaporative cool tower in conjunction with a solar chimney. Passive evaporative cool tower study.

Wind towers passive cooling iran what are wind towers. This can be achieved through use of fountains or more architectural designs such as the evaporative downdraft cooling tower also called a passive cooling tower. Functions of a wind tower the wind tower function based on several principles cooling water in cisterns. Passive evaporative cooling is one of the most efficient and long recognized ways of inducing thermal comfort in predominantly hot and arid climates.

In fact plants use their own evaporative cooling process which we refer to as transpiration. For passive cooling the combination of evaporative cooling and wind tower proves to be very effective and can reduce the temperature by up to 12 17 c. Evaporative cooling towers are used in many industrial applications to provide a continuous supply of cooled water. Evaporative cooling is most effective in hot and dry climates.

Baruch givoni in passive and low energy ecotechniques 1985. In addition to passive cooling techniques one of the most common and efficient ways to cool a greenhouse is through evaporative cooling. This approach works either by preventing heat from entering the interior heat gain prevention or by removing heat from the building natural cooling. Passive direct evaporative cooling can occur anywhere that the evaporatively cooled water can cool a space without the assist of a fan.

Similar to humans sweating a plant transpires moisture through its stomata. Evaporating water at the top of a cooling tower creates a downdraft of cooler air that can then be circulated to a specific space or area. In hot dry climates evaporative cooling towers will cool outdoor air and circulate it to a space or building.
