摘要
为了舒适和节能 ,空调需要调速运行。因此 ,提出了各种调速方法。根据驱动电机的不同 ,可以把空调风机调速方法分为直流调速和交流调速两种。本文综述了各种调速方法 ,尤其是无刷直流电机调速方法和交流电机变频调速方法。综述是就调速方法的原理。
For the sake of coziness and energy-saving, air-conditioners need running with speed-varying. So, various kinds of speed-varying methods are proposed. According to the kind of driving machines, the speed-varying methods of air-conditioner fans can be classified into two kinds: DC speed-varying and AC speed-varying. This paper summarys various kinds of speed-varying methods of the driving machines of air-conditioner fans, especially speed-varying methods of BLDC Motor and AC machine VVVF. The summarizations are carry out from three aspects: the principles, implementations, and advantages/disadvantages of these methods.
