Cooling towers performance

FIG, 12-17 Typical plot of cooling-tower performance at varying fan speeds. 

GPSA provides an extremely handy nomograph for cooling tower performance evaluation. The use of the nomograph is almost self-evident, especially with the examples that GPSA provides, condensed here. 

Altitude has an effect on cooling tower performance but in a unique way. Air handlers, air cooled condensers and the like are typically made to operate at higher speeds (or, with a steeper fan pitch) as altitude increases in order to maintain the...

Increases in loading, cooling range and humidity all tend to improve cooling tower performance. Two basic types of hyperbolic towers are counterflow and crossflow, as shown in Figure 4.12.

This provides curves for cooling tower performance and typical off design performance of centrifugal compressor chilled water systems. These graphs show typical coincident wet and dry bulb temperatures, in... 

Paper refers to the contents of the title paper in Vol. 25, N. 5, of May 1972, and presents an empirical analysis of a number of carefully conducted tests in cooling towers of the vertical, counter-flow type. In order to put cooling tower performance on a common basis the area to height factor is introduced. Parameters examined by Dr. Whillier are reexamined and use is made of the area to height factor to predict cooling tower performance.

Three Ways to Improve Your Cooling-Tower Performance—3. 

The size of the cooling tower, the flow rate and the wet bulb temperature determine the inlet and outlet water temperatures- but not the difference between them. Increased cooling tower performance can be achieved by adding surface area or by boosting the cfm.
