摘要

Four manufacturers provided detailed performance data on 36 fan/motor combinations applied in commercially available series and parallel fan-powered terminal units. The fan motors ranged in size from 0.33 to 1 hp (249 to 746 W). Data were provided for fan static discharge pressures ranging from 0.1 to 0.75 in. w.g. (25 to 187 Pa). All of the fan motors were electronically commutated motors. The performance data were analyzed to develop a generalized performance model that would be suitable for use in building energy simulation programs. The model developed had two components. First, the data for static discharge pressures ranging from 0.1 to 0.5 in. w.g. (25 to 125 Pa) were used to develop a correlation between the full-load power and the maximum airflow of the fan/motor combinations. These data were fit with a simple linear regression model. Second, part-load power and airflow data were evaluated over a wide range of controller settings for each fan/motor combination. The data were normalized to the airflow and power corresponding to the maximum controller setting for each static pressure. It was found that the normalized data for those fan motors whose full maximum power operations were less than 80% of the rating of the motor were problematic and were not used in the part-load evaluation. The normalized power and airflow were fit with a third-degree polynomial. The resulting full-load power correlation along with the part-load correlation can be used together in a building simulation program to estimate the part-load energy use of fan/motor combinations used in fan-powered terminal units that use electronically commutated motors.
