应用 Airpak 软件建立了燃气辐射供暖系统的地铁机车停车库温度场数学模型。通过对典型稳态阶段进行全尺寸模拟，并与实测数据进行对比，验证了模型的正确性。通过对既有策略的调研与分析，结合车库实际使用情况，提出了“轨道优先级”策略，并对两种策略下的车库温度场进行模拟，结果表明，两种策略均满足室内温度设计要求，并且针对停放不同数量机车的情况，“轨道优先级”策略下的工作区竖直方向上的温度梯度比既有策略低6％～18％，温度分布更合理。通过计算典型供暖日两种策略下的燃烧器逐时能耗，得到“轨道优先级”策略比既有策略耗气量节省116 m3／d，节能率达7．0％。因此，“轨道优先级”策略从实用、节能、经济角度均是可行的，可为同类型采用燃气辐射供暖系统进行分区供热的机车库的运行策略提供参考。

Develops the mathematical model for the temperature field of the subway locomotive garage with gas-fired infrared radiant heating system by Airpak software.Through the full-scale model simulation in the typical stationary phase and contrast with the measured data,verifies the accuracy of the model.Through the survey and analysis of existing operation strategy,and combined with the actual use situation,presents the “track priority”strategy.The established mathematical model is used for these two strategies.The results show that both of the strategies meet the design requirements.In “track priority”strategy,the vertical temperature gradient in workspace is 6%~18% lower than that with the existing strategy when there are different quantities of locomotives,so the temperature distribution is more reasonable.By calculating the hourly energy consumption of the burner under the two strategies in typical heating day,the “track priority”strategy saves gas by 116 m3/d,which has the overall energy-saving rate 7.0%.So the “track priority”strategy is feasible from the perspectives of application,energy saving and economy,which can also provide references for operation strategy of the same type of locomotive garage with gas-fired infrared heating system.
