摘要
通过变频技术改变中央空调系统中风机的转速来调节风量,并通过变频器调节冷水泵控制送风温度,以达到节能目的。
By using the frequency-change technology, we can change the rotational speed of the wind machine in the center air-conditioner system to regulate the wind volume and use the frequency changer to regulate the cold water pump to control the temperature to achieve the purpose of energy saving.
