非常经济

在设备的能耗方面,将空气流量调节到适应实际需求是至关重要的。对于AC风机,通常可以通过打开和关闭某个风机来实现。相比之下,绿色科技EC风机具有集成的无级调速控制功能,可根据实际需求调节风量。在降低速度n(P~n³)时,功耗Pe急剧下降。

一个简单的例子证明了其节省的巨大潜力:在标准运行中,并联安装4台风机,功率消耗为40kW。按年平均值计算,该装置在设计点运行时间为50%,在额定风量的一半运行时间为50%,则每年可以节能65MWh的能源。

效率等级高

能源效率的法律要求变得越来越严格。《电机生态设计指令》(EU 640/2009)规定IE2为欧洲最低效率等级。从2015年开始,必须满足IE3效率等级的要求。类似的规定也适用于其他国家,例如,在美国,效率等级IE3已经是强制性的。好消息:依必安派特公司生产的绿色科技EC电机已经超过IE4效率标准。这足以保证您可以对未来进行可靠性规划。

高效的同时也意味着成本的节省。最重要的是,基于需求的调速功能意味着仅使用实际需要的能量运行。
