font-family: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'; mso-bidi-font-size: 10.0pt"><font size="2">由于冷却塔的设备容量是根据在夏天最大热负载的条件下选定的，也就是考虑到最恶劣的条件，然而在实际设备运行中，由于季节、气候、工作负载的等效热负载等诸多因素都决定了设备经常是处于在较低热负载的情况下运行，所以设备的耗电常常是不必要的和浪费的。因此，使用变频调速控制冷却风扇的转速，在夜间或在气温较低的季节气候条件下，通过调节冷却风扇的转速和冷却风扇的开启台数，节能效果就非常显著</font></span></p> <p class="MsoNormal" style="margin: 0cm 0cm 0pt 21.25pt;
