高静压模块蒸发冷凝冷水机组在地铁的应用分析

结合地铁车站特征,介绍高静压模块蒸发冷凝冷水机组的组成及特点,从不同时期子机组台数选择、标准地铁车站的冷水机房布置、制冷系统整体控制方案、机组冷却循环水水质控制方案、机组效率及能耗分析等方面,对比分析整体式蒸发冷凝冷水机组与高静压模块蒸发冷凝冷水机组在地铁车站中的适用性。对比分析表明,高静压模块蒸发冷凝冷水机组具有折旧费用低、机房面积小、控制难度低、运输及检修方便等优点,在地铁车站中具有较好的应用潜力。

High Static Pressure Modular Evaporative Condensing Water Chiller for Metro Station

Based on the characteristics of metro stations, the structure and characteristics of a high static pressure modular evaporative condensing water chiller are introduced. The number of sub-units, layout of the chilling room, overall control strategy, control strategy of the quality of cooling water, and energy efficiency of water chillers differ between integral evaporative condensing water chillers and modular types. Through comparative analysis, a high static pressure modular evaporative condensing chiller is found to afford advantages, such as low depreciation cost, small machine room area, slight control difficulty, convenient transportation and maintenance, and satisfactory application potential in metro stations.
