基于室内均匀辐射场的西北农村节能建筑热工设计

THERMAL DESIGN OF ENERGY SAVING BUILDINGS IN RURAL AREAS OF NORTHWEST UNDER THE INDOOR UNIFORM RADIATION FILED

针对西北气候条件和当地农村建筑特点,利用室外综合温度作为围护结构热工分析的边界条件,提出了基于室内均匀辐射场的农村节能建筑围护结构热工设计方法,并对利用该方法与常规方法设计的围护结构内表面温度进行了对比分析。结果表明,该方法能有效降低室内不对称辐射温度差异,并能作为同类地区农村建筑围护结构设计的理论参考。

With the climate conditions in northwestern areas and the characteristics of local buildings, and by using outdoor solair temperature as the boundary conditions for thermal analysis of envelope, the paper suggests the thermal design method of envelope for energy saving buildings in rural areas under the indoor uniform radiation field, also, the interior surface temperatures in envelope to be designed with normal method and new method were compared and analyzed. The results shown that the new method can effectively reduce the differences of indoor asymmetry radiation temperature. Also, the new method can be used as the theoretical reference for envelope design of rural buildings in the same areas.
