墙体材料对农村民居围护结构传热影响分析

以大庆市农村民居的外墙为和当地气候的特点为研究对象,计算得出该地区冬季的室外综合温度,并以此温度为输入条件循环作用于墙体,并根据实际情况建立多种材料的墙体模型,利用CFD软件计算在该温度下的不同种墙体材料对应的逐时热流密度,进而得出各种墙体材料的保温性能。

ANALYSIS ON THE INFLUENCE OF WALL MATERIALS ON THE HEAT TRANSFER OF RURAL RESIDENTIAL BUILDING ENVELOPE

On the external wall of rural houses in Daqing city and local climate characteristics as the research object,calculates the outdoor colligate temperature in winter in this area,and use the temperature as the input conditions cyclically act on the wall,And according to the actual situation to establish a variety of materials wall model,Calculate the corresponding time-dependent heat fluxes of different wall materials at the temperature by the CFD software,and then come to the insulation property of various wall materials.
