Cooling-WATER calculations

C-tower is a contraction of Cooling T O W E R water and chemical consumption calculations. C-tower does all the calculations needed to estimate the use of water and chemical treatment products within a cooling tower. This latest version has added the ability to calculate usage and costs associated with a short-term feed to the recirculation line as well as corrections for the percentage of active materials within a given product. C-tower can work with US, metric or imperial units or any combination of them and any currency. C-tower uses several very common calculations from the open literature, many of which are used by the various watertreatment suppliers and consultants. To fully interpret the results, it should be noted that conditions within a cooling tower may differ from those on which the calculations are based due to factors such wind speed and humidity. The calculations do give a reasonable average over the year; however, the authors can assume no responsibility for any decision based upon the results of the calculations.

Cooling Tower Dynamics

Water is our most common cooling medium for industrial and HVAC systems. A simple oncethrough system takes its water from the source (e.g., a river); circulates it across the equipment to remove heat and returns the warmed water to the source. With major systems, this requires vast quantities of water. When it is not available and/or too expensive to purchase, the water can be reused and recycled through evaporative EVAPORATION - residual solids concentrate cooling. Instead of discarding the in system water - Rate of loss...
