REVIT + AutoCAD 3D design and visualization software allows STAR to design, construct and maintain the highest quality and most efficient cooling towers in the industry Ready To Get Started? We’ve been designing, constructing, repairing and upgrading cooling towers for over 60 years. The cooled water collects at the bottom of the cooling tower and is returned to the plant. Example: Calculate the approach and effectiveness for a cooling tower with inlet water. Subsequent design optimization may occur from this starting point. These equations can be incorporated into software to predict cooling tower.

• the value of NTUm for design conditions is calculated; • the line of slope n and constant C is plotted and adjusted on the design point; • for other operating conditions, determined by the fluid flows, the abacus allows us to find, at abscissa L/G and on the tower characteristic line, the new values of NTUm and approach, which determines the outlet water temperature and therefore the capacity. The air outlet temperature is deduced. For another cooling or other air wet bulb temperature, it is possible to recalculate another abacus. Knowing the values of variables (NTUm, L/G) from the original chart, we get the new approach. It seems necessary to warn the reader: we tried to implement this approach on some experimental data either provided by the manufacturers or that we were able to get, and we realized that, when applied to NTUm, the correlations of the type Merkel lead to accurate reconstructions with values n and m close to those we have indicated. However they may be different when we use an (epsilon, NTU) approach similar to those of dry heat exchangers.

We recommend extreme caution when using this analogy, and think it is better to apply the Merkel model which has been proven and is used by the profession. The calculations are slightly more complex, and can be made with small programs or Excel macros.
