摘　　要：严寒地区被动式建筑新风采用地道风系统可有效降低建筑能耗。以哈尔滨地区为严寒地区代表城市,研究了不同地层深度下的土壤温度,针对钢筋混凝土和不锈钢两种材质的管道,分析了入口温度、管道风速、管道直径、管道数量对地道风出口温度的影响。综合考虑地道风出口温度,管道成本和工程成本等因素,严寒地区地道风系统埋深宜在6~9 m范围,管道直径宜选择在0.8~1.6 m,管道数量宜选择在3~8根。Tunnel wind can effectively reduce energy consumption of Passive Housing in severe cold area.Taking Harbin as the representative city of cold area,the soil temperature at different strata depths was studied,and the influence of inlet temperature,pipe wind speed,pipe diameter and number on the tunnel outlet air temperature was analyzed regarding the reinforced concrete pipes or stainless steel pipes.Taking factors such as outlet air temperature,pipeline cost and engineering cost into consideration,the buried depth of tunnel wind system in Harbin should be within the range of 6-9m,the diameter of pipelines should range from 0.8m and 1.6m,and the number of pipelines should be fall in between 4 and 9.
