地铁车站隧道排热系统节能模式探讨

Discussion on energy saving mode of heat extraction system in underground railway station tunnel

建立了地铁车站隧道排热计算模型,根据模型理论计算结果提出了车站排热风机节能运行模式。实测了某改造工程地铁车站区间隧道温度、CO2浓度、人员新风量。结果表明,测试值均满足规范要求,且排热风机能耗减少40%。

Establishes a heat extraction model of underground railway station tunnels. Proposes the energy saving mode of heat extraction fans based on the calculation results. Tests the temperature, carbon dioxide concentration and outdoor air volume of passengers in the underground railway station tunnel of a reconstruction project. The results show that the test values can satisfy the design specifications, and the energy consumption of heat extraction fans can reduce by 40%.
