摘　　要：蒸发冷却与传统的机械制冷相结合,既可以实现节能,又能做到稳定控温,实现了2种技术的优势互补。相关产品虽已出现,但一直缺少相关技术评价标准。结合介绍最新的美国标准ANSI/ASHRA Standard 212-2019,就蒸发冷却设备的性能测试程序和计算方法、蒸发式空气冷却器作为预冷器时的性能评估方法,以及蒸发冷却用水效率等问题进行了讨论。期望能为我国蒸发冷却空调技术标准的完善以及相关产品的规范提供参考。The combination of evaporative cooling and traditional mechanical cooling not only can realize energy saving,but also can achieve stable temperature control.It realizes the complementary advantages of the two technologies.Although the relevant products have appeared,there has been a lack of relevant technical evaluation standards.The latest American Standard ANSI/ASHRA Standard 212-2019 is introduced,the performance test procedure and calculation method of evaporative cooling equipment,the performance evaluation method of evaporative air cooler as a precooler as well as the water efficiency of evaporative cooling are discussed.It is expected to provide reference for the improvement of technical standards of evaporative cooling air conditioning and the specification of related products in China.
