大多数ICI客户认为节水和节能的计划比其他计划更具吸引力 仅节约用水的倡议。两者兼备的计划通常具有更短的回报期。 通常，会有能源回扣，以进一步抵消成本，并对设备进行改造 通常涉及标准的现成技术，而不是详细的工程评估 回收/再利用项目所需。因此，节约用水和能源的倡议可能会失败 为提高水资源效率提供绝佳机会。 提高蒸发传递效率的措施还可以通过减少蒸发来节约用水 损失。本文讨论了变速传动（VSD）在冷却塔风机中的应用 提高蒸发传输效率，提高整体能源效率。论文还 介绍加利福尼亚州和俄勒冈州的拟议法规变更，以进一步 在新设施实施VSD，以及改造的经济优势 现有冷却塔，配备节能节水设备。本文还提出了一个解决方案 案例研究，报告ICI客户关于实施 冷却塔水/能源倡议。在冷却塔中使用VSD的优点包括: 在相同的散热能力下，能耗降低高达75%； 在不增加供水量的情况下，用水量可减少25% 浓缩循环； 消除飞溅- 因风机频繁关闭和关闭而造成的水损失 在…上 虚拟消除机械冲击和噪声污染问题；和 稳定的冷却塔温度，可在 工厂的制冷设备。包括数字。

Most ICI customers find initiatives that save water and conserve energy more attractive than initiatives that save water alone. Initiatives that do both typically have shorter pay back periods. Frequently, there are energy rebates available to further offset the costs, and equipment retrofits usually involve standard, off-the shelf technologies, instead of the detailed engineering evaluations required by recycling/reuse projects. Consequently, initiatives that save water and energy may provide excellent opportunities for water efficiency programs to promote conservation. Measures that increase the evaporative transfer efficiency also save water by reducing evaporation losses. This paper discusses the application of variable speed drives (VSD) in cooling tower fans to improve evaporative transfer efficiency and increase overall energy efficiency. The paper also presents proposed Code changes in the States of California and Oregon to further the implementation of VSDs at new facilities, as well as the economic advantages of retrofitting existing cooling towers with energy and water efficient equipment. The paper also presents a case study that reports ICI customers' comments and experiences regarding implementation of cooling tower water/energy initiatives. Advantages associated with the use of VSDs in cooling towers include: energy consumption reduction up to 75% for the same heat rejection capacity; water consumption reduction up to 25%, without increasing the number of concentration cycles; elimination of splash-out water losses due to the fans frequently being turned off and on; virtual elimination of mechanical shock and noise pollution issues; and, steady cooling tower temperatures, which produce additional energy savings at the plant's chiller equipment.
