Passive Evaporative Cooling Tower

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.

Passive evaporative cooling tower.

Passive direct evaporative cooling can occur anywhere that the evaporatively cooled water can cool a space without the assist of a fan. Passive evaporative cool tower study. Passive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building in order to improve the indoor thermal comfort with low or no energy consumption. In an induced draft counter flow cooling tower ambient air is drawn upwards through the structure by an axial flow fan mounted on the top of the tower.

Evaporative cooling is the most economical concept for cooling of a building. Wind towers passive cooling iran what are wind towers. In fact plants use their own evaporative cooling process which we refer to as transpiration. Analysis and evaluation of a passive evaporative cool tower in conjunction with a solar chimney.

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. 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. Baruch givoni in passive and low energy ecotechniques 1985. Functions of a wind tower the wind tower function based on several principles cooling water in cisterns.

Rain water is the perfect source for the water used in wind towers because it. Passive evaporative cooling is one of the most efficient and long recognized ways of inducing thermal comfort in predominantly hot and arid climates. Similar to humans sweating a plant transpires moisture through its stomata. Evaporating water is what creates the cooling and makes evaporative coolers and wind towers work.

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. This approach works either by preventing heat from entering the interior heat gain prevention or by removing heat from the building natural cooling.
