The use of brushless DC motor
Central air conditioning is an absolute energy-hungry machine; in addition, the noise is the attention manufacturers and buyers focus on. In the April 7-9 meeting of the China Refrigeration 2011, the DC brushless motor fan coil noise characteristics are "sought after’ air-conditioning manufacturers because of its excellent energy-saving.
As the name implies, the brushless DC motor used in fan coil is brushless DC motor. Compared to ordinary AC motor, the electronic means of changing direction DC brushless motor used replace the traditional mechanical changing way, which to avoid the mechanical change in the electromagnetic interference and electromagnetic noise, so it make indoor environment more quiet and comfortable.
In addition, for the fan, the higher speed is, the greater the noise. However, brushless DC motor can achieve low-speed operation, thus further reducing the noise value.
