杭州地铁1,2号线车站通风空调系统设计比较与分析

Comparison and analysis of ventilation and air conditioning system design in Hangzhou underground railway line 1 and line 2

以杭州地铁1,2号线各1座标准岛式地下车站为研究对象,对其通风空调系统的设计进行比较,包括隧道通风系统中区间隧道风机与车站隧道排热风机的配置、公共区通风空调系统中小新风机的设置、变电所空调形式、冷水机组的选型与配置等。分析了各自的优缺点,就合理选择系统与优化设计给出了结论与建议,为类似工程通风空调系统的设计提供参考。

Taking two standard island stations in Hangzhou underground railway line 1 and line 2 as research objects, compares the ventilation and air conditioning system design of them, including the configuration of tunnel ventilation fans and U/O fan in tunnel ventilation system, minimum outdoor air requirement fan configuration in air conditioning system for the public area, air conditioning mode of transformer substation, and selection and configuration of chillers. Analyses the advantages and disadvantages of them, points out some recommendations and conclusions for the system reasonable choice and optimized design, and provides some references for ventilation and air conditioning system design of similar projects.
