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.Electronically commutated motors (ECMs) have significantly improved the performance of Fan Powered Terminal Units (FPTUs). This session provides comparisons of the estimated performance of systems employing ECM versus PSC controlled motors for series and parallel terminal units in five different U.S. cities. The simulations were based on experimental data from three terminal unit manufacturers and two motor manufacturers that were used to develop semi-empirical models of FPTU airflow and power. The papers in this session are an extension to the prior work on FPTUs with SCR controllers in 1292-RP.Modeling the Performance of ECM and SCR Series Fan Powered Terminal Units in Single-Duct VAV Systems (CH-12-017)Dennis L.
