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.

Passive direct evaporative cooling can occur anywhere that the evaporatively cooled water can cool a space without the assist of a fan. Baruch givoni in passive and low energy ecotechniques 1985. 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. Similar to humans sweating a plant transpires moisture through its stomata.

Wind towers passive cooling iran what are wind towers. Analysis and evaluation of a passive evaporative cool tower in conjunction with a solar chimney. Evaporative cooling towers are used in many industrial applications to provide a continuous supply of cooled water. Evaporating water is what creates the cooling and makes evaporative coolers and wind towers work.

This approach works either by preventing heat from entering the interior heat gain prevention or by removing heat from the building natural cooling. Passive evaporative cool tower study. 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. In addition to passive cooling techniques one of the most common and efficient ways to cool a greenhouse is through evaporative cooling.

Passive evaporative cooling is one of the most efficient and long recognized ways of inducing thermal comfort in predominantly hot and arid climates. Functions of a wind tower the wind tower function based on several principles cooling water in cisterns. In fact plants use their own evaporative cooling process which we refer to as transpiration. Evaporative cooling is most effective in hot and dry climates.

Rain water is the perfect source for the water used in wind towers because it. Evaporative cooling is the most economical concept for cooling of a building. 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.
