蒸发冷却是已知的最古老的冷却形式，但这并不是这种节能冷却方法最令人惊讶或最重要的地方。令人惊讶和重要的是，当建议使用蒸发冷却器时，工程师和顾问经常提出的问题和评论。其中一些问题是，“什么是蒸发冷却器？”“它是如何工作的？”“他们在亚利桑那州可能会很满意，但他们在这里不工作，湿度太高”；“1不会安装一个，因为会有水从墙上流下来，穿过地板”； “我想使用它们，但它们会导致金属零件生锈。”引文:研讨会，ASHRAE交易，第95卷，pt。1989年，芝加哥

Evaporative cooling is the oldest form of cooling known but that is not the most surprising or important thing abouthis energy-efficient cooling method. What is surprising and important are the questions and remarks often made by engineers and consultants when the use of evaporative coolers is suggested. Some of these are, "What is an evaporative cooler?" "How does it work?" "They might be satisfactory in Arizona, but they won’t work here, the humidity is too high"; "1 wouldn’t install one because there would be water running down the walls and across the floor"; "1 would like to use them but they would cause rusting of metal parts."
