民用建筑电动机“源头”节能浅析

Analysis of Energy Saving of Motor“Source”in Civil Buildings

本文从电动机工作特性曲线分析入手,通过计算分析,强调控制电动机运行效率和功率因数的重要性。再从项目设计中水泵最初的参数计算和选型切入,得出电动机设备选型不合理所造成的设备投资、设备运行能耗的增加,提出应重视电动机源头参数选型的合理性,从而降低建筑能耗,达到真正的节能设计。

The article starts from the analysis of the working characteristic curve of the motor.Through calculation and analysis,emphasis is laid on the importance of motor operation efficiency and power factor.Then starting from the calculation and selection of pump parameters in project design,obtain increase in equipment investment and energy consumption for equipment operation caused by unreasonable selection of motor equipment.It is pointed out that attention should be paid to the rationality of the selection of motor source parameters.To reduce building energy consumption,reaching real energy saving design.
