本文件对风机效率进行了分类。它适用于使用以下特定组件组合的所有电机驱动风扇系统:a) 根据公认的性能标准确定的风扇气流性能;b) 本文件规定的标称电机效率的多相感应电机;注1:明确排除了其他类型的电机。c) 用于单台电机的脉宽调制变频驱动器(VFD);注2:不包括为多个并联风扇电机提供服务的单个VFD。d) 使用V带、平带、齿带或联轴器的机械动力传动。
This document establishes a classification for fan efficiency. It applies to all electric-motor-driven fan systems that utilize a specific combination of components as defined below:a) fan airflow performance determined in accordance with an accepted performance standard;b) polyphase induction motors with nominal motor efficiency specified in this document;NOTE 1 Other types of motors are explicitly excluded.c) pulse-width modulated variable frequency drives (VFDs) for use with single motors;NOTE 2 Single VFDs that service multiple, parallel fan motors are excluded.d) mechanical power transmissions that utilize V-belts, flat belts, cog belts or couplings.
