09-20: Affecting Test UncertaintyThe CTI ATC 105 test codes give us guidance to conduct a cooling tower thermal performance test with results having a reasonable uncertainty. A test configuration with a different number of measurements and instrumentation can lead to changes in the uncertainty and the resultant calculated tower capability. This presentation will describe these changes for a project with water flow measurements in the main line and on individual risers plus

and operating reliability improves compared to cooling tower/surface condenser

the present codes have been remiss in the exact specification of inlet air sensor deployment

and lighting

Although copper was the metal of interest

Although this paper is only indirectly related to the subject of this symposium and is being delivered by a biologist with little knowledge of cooling towers

A well-designed evaporative cooling tower installation is critical to achieving the maximum benefit from the system investment

and reduction of noise

especially electric generation or cogeneration stations require permit approval that contain criteria such as noise limits

The tests were conducted under carefully controlled laboratory conditions in a large counterflow test cell

or to the operating engineer which you are sure to have

certain cooling water problems are solved most effectively when the supplier openly discloses the chemical formulation and works with the end-user to customize a chemical treatment product specific for that application

Previous CTI publications show that certain cooling tower configurations and designs are more responsible than others for creating recirculation environments
