A cooling tower is a ‘heat rejection’ device which extracts waste heat to the atmosphere through cooling of water to a lower temperature.
It is well known fact that in a cooling tower (natural draft or forced draft) heat transferred, from hot water to atmosphere, is always dependent upon, ‘contact time period’ and ‘surface area of water’, coming in contact with naturally or artificially blown air.
Presently, in cooling tower(s), to obtain a shower of hot water from a pipe grid; nozzle(s) of required size(s), at a required spacing, are being installed.
From practice, it has been observed that from very first nozzle (installed near to the source of supply of hot water i.e. pumping station), a sufficiently larger quantity of hot water, at a fast speed, gets released.
Further, as we move away from pumping station, towards tail end of the said pipe grid; at downstream of nozzle(s), not only the availability of hot water gets reduced but also the water pressure and flow rate of flowing water gets reduced. This results in unequal distribution of water, in the said pipe grid. Also, water coming out from these nozzles; has a very little ‘surface area of water’ and ‘time period’, coming in contact with the air. Consequently, from such grids, there is always an unequal and inefficient cooling of hot water.
This technology regulates the pressure and flow rate of a flowing fluid, simultaneously. Because, at downstream of this technology, water flows at a much lower speed than a speed without this technology; this activity, enhances sufficiently, the ‘contact time period’ and ‘surface area of water’ coming in contact, with blown air and hence in better cooling of hot water.
