Problems Related to Outside Installation

With the exception of very small units, cooling towers are located outdoors, and their placement has a significant bearing on the overall cost of the initial installation and the effectiveness of the operation. 

This adulteration by the exhaust air raises the wet-bulb temperature of the entering air above that of the ambient air, reducing the tower s overall performance. 

These problems are typical in mechanical-draft cooling towers and virtually nonexistent in hyperbolic towers because of the height of vapor discharge. The magnitudes of interference and recirculation depend primarily on wind 

Interference from industrial installations or multiple tower arrangements can result from poor planning of plant additions. Careful planning will provide the most effective cooling results. In general, interference can be
