蒸发型冷风机是利用水蒸发制冷，送风距离远、风量大，能使封闭式的场所温度分布均匀，兼具过滤功能。令室内环境舒适，含氧量高，空气清新，而传统中央空调是直接利用氟里昂制冷，送风温差大，风量小，房间温度不易均匀。
The steam type cooling fan uses the water evaporation refrigeration, the air supply distance is far, the air volume is large, can make the closed place temperature distribution even, has the filtering function. It makes the indoor environment comfortable, high oxygen content and fresh air, while the traditional central air conditioning uses freon refrigeration directly, with large air temperature difference, small air volume and uneven room temperature.
