针对西北地区简述了蒸发冷却冷水机组的主要形式,浅析了应用两级蒸发冷却冷水机组(IDEC)的理论,在结合实际应用结果的前提下假设了间接蒸发冷却段与直接蒸发冷却段的效率,结合西北六个省区不同城市气象数据,对蒸发冷却与机械制冷冷水机组的流量配比进行了量化分析研究,针对蒸发冷却与机械制冷冷水机组分别单独运行时,统计计算出单独运行蒸发冷却冷水机组不满足小时数,并分析了运行机械制冷冷水机组的小时数。
In this paper, the main forms of evaporative chiller are briefly introduced in Northwest China. The theory of two-stage evaporative chiller (IDEC) is analyzed. Based on the practical application results, the indirect evaporative cooling section and the direct evaporative cooling section Efficiency and combined with the meteorological data of six cities in Northwest China, the quantitative analysis of the flow ratio between evaporative cooling and mechanical chiller is carried out. When evaporative cooling and mechanical chiller are operated separately, Cooling chillers do not meet the number of hours and the number of hours of operating chillers is analyzed.
