Full Description

This product is a PDF that contains links to files that consist of PowerPoint slides synchronized with the audio-recording of the speaker (recorded presentation), PDF files of the slides, and audio only (mp3) as noted.

Manufacturers adopt AMCA standard methods in the laboratories for performance testing and generate fan curves. In-situ fan performance and system curve in almost all situations do not match laboratory results. Of course, there are different reasons for these differences. One reason is the use of different techniques and tools used to measure the performance in the laboratory and field. Also, the accuracy of the available field methods are not well-established and standardized. This seminar discusses the different methods and tools available and used together with their comparisons.
