【英文篇名】 Discussion on cooling technology for underground railway air conditioning system 【作者中文名】 何叶从; 付祥钊; 肖益民; 周杰; 钟星灿; 【作者英文名】 He Yecong; Fu Xiangzhao; Xiao Yimin; Zhou Jie and Zhong Xingcan Chongqing University; Chongqing; China; 【作者单位】 重庆大学; 中铁二院集团有限责任公司; 【文献出处】 暖通空调, Heating Ventilating 喷雾冷却; 冷水机组; 喷雾间接蒸发冷却冷凝器; 【英文关键词】 underground railway; spray cooling; water chiller unit; spray indirect evaporative cooling condenser; 【摘要】 针对地铁空调冷却水系统的特殊要求,提出了喷雾间接蒸发冷却器与喷雾间接蒸发冷却冷凝器两种方案,简要分析了两种方案的工作原理和节能效果,计算表明,采用喷雾冷却设备替代1台600m3/h机械通风冷却塔时,在不考虑冷却塔运行费用的基础上,仅冷却塔补水水费一项每年就可节约17万元。 【英文摘要】 In view of the special demand of underground railway air conditioning for its cooling water system, puts forward two schemes—the spray indirect evaporative cooler and the spray indirect evaporative cooling condenser. Briefly analyses the working principle and energy saving effects of the two schemes. The calculation results show that when the spray cooling equipment is adopted to replace the mechanical ventilation cooling tower with water flow volume of 600 m3/h, and the operating cost of the cooling tower ...
