天津地区农村住宅地下浅埋管通风模拟研究

Ventilation Simulation of Rural Underground Shallow Buried Tube in Tianjin

地下浅埋管自然通风技术又称地道通风技术[1],是利用机械抽风或烟囱效应的原理将由土壤预冷(预热)的空气经地下埋管抽进房间进行被动式通风的绿色技术。随着农村生活水平的提高,农村住宅建筑应满足健康、舒适、能源有效利用和环境保护等方面的要求。利用Fluent公司推出的专业软件Airpak 2.1对地下浅埋管技术在农村住宅中的应用进行可行性分析,为改善农村住宅的热环境和热舒适性提供方法和理论依据。

The natural ventilation technology of underground shallow buried tube uses the mechanical convulsions or chimney effect as principles.This technology is environmental-friendly,it can use soil energy heating enter indoor air for passive ventilation.Rural residential building should meet the requirement of health,comfortable,energy efficient utilization and environmental protection as the improvement of living standards in rural areas.The professional software Airpak 2.1 is used,which made by Fluent company,to analyze the technical feasibility of underground shallow buried tube and provide theoretical basis.
