摘要：
通过间接蒸发冷却技术制备冷水，解决常规间接蒸发冷却系统风道占用空间大、风机耗电高的问题，是在干燥地区推广应用蒸发冷却技术的关键。介绍了间接蒸发冷却冷水制备技术的原理、研发机组的实测性能及其在工程中的实际应用效果。综述了目前间接蒸发冷却技术的应用状况和推广前景。所研发的间接蒸发冷水机出水温度16~19 ℃，达到室外湿球温度和露点温度的平均值，可作为空调的冷源。这种间接蒸发冷水机及其系统在西北地区已经实现了规模化推广。
Abstract：
The key to promoting application of evaporative cooling technology in dry regions is to produce chilled water by indirect evaporative cooling technology, to solve the problems of too large space occupied by air ducts and too high energy consumption of fans in conventional indirect evaporative cooling system that uses air as the coolant. Presents the principle of chilled water producing technology by indirect evaporative cooling, testing performances of the unit developed and actual application effects. Reviews the applications of this technology at present and prospects in the future. The outlet temperature of indirect evaporative water chiller units is 16 to 19 ℃, reaching the average value of local outdoor wet-bulb temperature and dew-point temperature, and can be used as the cold source. The indirect evaporative chiller and its system have been promoted to a larger extent in northwest China.
