针对西北地区独特的气候特点,分别提出了蒸发冷却+置换通风和蒸发冷却+干式风机盘管2种空调系统形式可在喀什地区实际工程中应用.通过对比发现,第1种系统形式比传统电制冷空调系统节能53%,第2种系统形式比传统电制冷系统的制冷机房内设备节能71%,2种系统节能效果显著.通过对送风状态点露点分析,蒸发冷空调系统无凝结水产生,可避免室内环境污染.蒸发冷却空调系统的独特优势决定了其在西北地区的广泛应用前景.%For the unique climate characteristics of Northwest,the paper proposes evaporative cooling and displacement ventilation, evaporative cooling and dry fan coil system which were used in practical engineering in Kashi. By comparison, the first system can save more 53% energy than electric refrigeration system, the second system can save more 71% energy than conventional refrigeration system which in the refrigerating station, the energy saving effect is remarkable. Through analyzing the dew point of the air supply state point, the evaporative cooling air conditioning system has no condensate which can avoid the indoor environmental pollution. The unique advantage of evaporative cooling air conditioning system determines the wide application prospect in the Northwest China.
