85-18: A System Efficient Approach to Cooling Tower Energy Modifications Drift

85-18: A System Efficient Approach to Cooling Tower Energy Modifications DriftThe paper will discuss several modifications that can be made to existing crossflow and counterflow towers to enhance overall energy savings. The author will demonstrate the advantages of several modification choices from an optimized cost efficiency standpoint. Several typical examples will be presented along with appropriate charts and graphs to clarify proper application.

This paper will present current laboratory and field fouling evaluation methods

auxiliary power

flexibility and finally price

The basis for these concerns relate to measurable amounts of copper that can be detected in cooling waters in contact with copper in the incoming water

specialized procedures were developed to characterize the condition of different materials

the options available to the designer to improve the performance of these cooling towers are limited

environmental constraints

and by creating an environment for destructive and pathological organisms such as sulfate-reducing bacteria (SRBs) and Legionella pneumophila

today's equipment now addresses the concentration and handling of separated solids

Additionally

If the enhanced cooling tower is operated as an evaporative chiller that can completely displace refrigeration equipment

are vital to allow the ACC supplier to properly rate the equipment and guarantee its performance
