蒸发冷却与机械制冷冷水机组的流量配比的初探

Discussion of Water Flow Ratio between Evaporative Cooling Chiller and Mechanical Refrigeration Chiller

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。

Aiming at the northwest district, the main form of the evaporative cooling chiller was sketched, and the principle of two-stage evaporative cooling chiller (IDEC) was simply analyzed. Combining the results of the practical application, the efficiency of indirect and direct evaporative cooling section was assumed. Different city meteorological data of northwestern six provinces were taken into consideration, and quantitative analysis and study on evaporative cooling and mechanical refrigeration chiller flow ratio were performed Aiming at the evaporative cooling and mechanical refrigeration chiller running alone, the dissatisfy hours of the individual operation of the evaporative cooling chiller were statistically calculated, and the hours of the operation of the mechanical refrigeration chiller was analyzed.
