建筑自动化，尤其是空气输送系统，依靠变速风扇来改变整个建筑内区域的温度和湿度。过去，单速电机向空气处理分支的所有部分平等地输送空气，只有开或关，但现在，有了VFD，建筑的能效可以通过以最低的所需功率运行来大大提高，以确保舒适性。

泵应用中的VFD

空气的流速可以随着风扇速度的变化而变化，我们将完全相同的策略应用于来自变速泵。当泵全速运转时，多余的压力必须通过减压再循环阀排出。所有多余的流量都是被浪费的能量。通过调节泵速，可以控制精确的压力和流速，从而节约能源。

每个三相电机环境中的VFD

我无法描述或列出所有的VFD应用。只需在互联网上搜索“哪里使用三相电机”，很可能成千上万种情况中的每一种都不止一次配备了VFD。

Building automation, especially air delivery systems, relies on variable speed fans to change the temperature and humidity of the entire building area. In the past, single speed motors delivered air equally to all parts of the air handling branch, only on or off. However, now with VFD, the energy efficiency of buildings can be greatly improved by operating at the lowest required power to ensure comfort.

VFD in pump applications

The air flow rate can vary with the speed of the fan, and we will apply the exact same strategy to the variable speed pump. When the pump is running at full speed, excess pressure must be discharged through a pressure reducing recirculation valve. All excess traffic is wasted energy. By adjusting the pump speed, precise pressure and flow rate can be controlled, thereby saving energy.

VFD in each three-phase motor environment

I cannot describe or list all VFD applications. Just search “where to use three-phase motors” on the Internet, and it is likely that each of thousands of cases is equipped with VFD more than once.
