当室外温度降到冰点以下时，水将不可避免地结冰。开放式冷却塔由于其固有的运行特性，容易形成冰。因此，如何对结冰进行管理（而非消除）成为一个课题。幸运的是，还有其他的解决方案。 闭式冷却塔被用于许多特定的应用，它也是在严冬气候条件下蒸发式冷却应用的理想选择。如果结冰现象没有得到合适的管理，预计会出现热力性能下降、部件故障和额外的现场维护。因此，要确保您的闭式冷却塔的设计、选型和制造都考虑到冬季。 选型: • 理想的解决方案是：选择带翅片盘管的闭式冷却塔。这可提升机组的环境干球转换温度，并允许闭式冷却塔在春季、秋季和冬季尽可能多地进行干运行（喷淋泵关闭）。 • 选择一台闭式冷却塔，令其能够实现最佳的自由冷却运行。通常，冬季冷却条件比夏季更难实现，因此应将冬季运行参数作为设备的选型基础。 • 在长期干运行时，为冷水盘设置自动排水系统，这可消除不必要和过度的水盘电加热器工作。 工艺流体: • 根据当地气候，在冰冻环境下利用乙烯乙二醇或丙烯乙二醇溶液来保护工艺流体。 • 记住乙二醇在传热方面比水的效率低。在优化机组容量时，必须考虑到乙二醇导致的热力性能下降。 • 运动中的流体不易结冰。应遵守制造商关于防冻最低流速的建议，特别是当工艺流体为水时。 • 30%的乙二醇溶液或30%的丙二醇溶液可防止工艺流体冻结的温度分别低至6.7℉（-14℃）和9.2℉（-12.7℃），低于该温度，则出现结晶
