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.
