Zero bleed for cooling towers, also called zero blow-down for cooling towers, is a process for significantly reducing the need for bleeding water with residual solids from the system by enabling the water to hold more solids in solution.
This is just a definition. The more common term is blowdown, as stated in the terminology list in the Cooling tower article. --Pakaraki 02:33, 8 January 2012 (UTC) Support. The single sentence and 3 references belong in the main Cooling tower article. Reify-tech 14:57, 1 February 2015 (UTC)
For arid climates with a great wet-bulb depression, cooling towers can provide enough cooling during summer design conditions to be net zero. For example, a 371 m 2 (4,000 ft 2 ) retail store in Tucson, Arizona with a sensible heat gain of 29.3 kJ/h (100,000 Btu/h) can be cooled entirely by two passive cooling towers providing 11890 m 3 /h ...

In the present era, mechanical induced draft–type cooling towers are employed in cooling of water. Performance testing of cooling towers (both IDCT and NDCT) shall be carried out as per ATC-105 [4] at a time when the atmospheric conditions are within the permissible limits of deviation from the design conditions.
Specific spray pond surface areas tend to range between 1.2 and 1.7 m 2 per m 3 /h of water to be cooled. The width chosen for a drift channel around the active zone of the pond (containing the sprays) is dependent on a number of factors, including the prevailing wind strength, the average size of the spray droplets produced by the nozzles, and the presence of any nearby structures which may ...
Air bled from the engine fan is blown across the pre-cooler, located in the engine strut, and absorbs excess heat from the service bleed air. A fan air modulating valve (FAMV) varies the cooling airflow to control the final air temperature of the service bleed air. Notably, the Boeing 787 does not use bleed air to pressurize the cabin.
Cooling towers, although quite similar, are not technically chimneys, as they do not convey any products of combustion. Pages in category "Cooling towers" The following 4 pages are in this category, out of 4 total.
