            摘要:

            分析了新疆吐魯番地區葡萄晾曬空間——晾房對當地生土建筑熱環境的作用。利用現場實測與軟件模擬相結合的方法,研究了葡萄晾房的熱環境特點及其對下部空間熱環境的影響。在保證晾房內部晾曬條件適宜的情況下,提出了改善晾房熱環境的策略。結果表明:晾房內部具有溫度高、輻射強和通風換氣次數大的特點;夏季晾房可使下部空間日均空氣溫度降低1.36 ℃;晾房屋頂增設0.8 m長的挑檐可使晾房日平均溫度降低0.3 ℃、下部空間日平均溫度降低0.2 ℃左右;增大晾房開洞率可降低其溫度,開洞率為0.272最合理;根據土坯磚規格及晾房開洞率,洞口尺寸寬10 cm、高15 cm最適宜。

            Abstract:

            Analyses the effect of grape-drying rooms on the thermal environment of native adobe buildings in Turpan, Xinjiang. Investigates the characteristics of the thermal environment of the grape-drying room and its influence on the thermal environment of the lower space by the method of field measurement and software simulation. Under the condition of ensuring the suitable drying conditions, puts forward the strategies to improve the thermal environment of the drying room. The results show that the drying room has the characteristics of high temperature, strong radiation and large air exchange rate. The drying room can reduce the daily average air temperature of the lower space by 1.36 ℃. The addition of 0.8 m long overhanging eaves on the roof of the drying room can reduce the daily average temperature of the drying room by 0.3 ℃ and that of the lower space by about 0.2 ℃. Increasing the hole-opening rate of the drying room can reduce the temperature, and the hole-opening rate of 0.272 is the most reasonable. According to the specifications of adobe bricks and the hole-opening rate of the drying room, the hole size of 10 cm width and 15 cm height is the most suitable.
