墙体材料及其组合对日光温室墙体保温性能的影响

利用热反应系数法和日光温室热环境的数学模型模拟分析了日光温室墙体得热量、墙体温度以及室内气温,比较了墙体材料的不同组合对保温性能的影响。结果表明,对不同厚度砖墙聚苯板隔热材料的厚度以0.10m为宜;相同厚度隔热材料在砖墙厚度较薄时保温效果优于较厚的砖墙;砖墙厚度较薄时材料的排列秩序对保温影响较明显。

Effects of different wall materials on the performance of heat preservation of wall of sunlight greenhouse

The performance of heat preservation of wall was simulated and analyzed by the method of heat response factor and the model of thermal environment of sunlight greenhouse.The effects of heat preservation of different wall materials were compared through measuring the heat gained,temperature of wall and inner air temperature of greenhouse.The results show that the best thickness of polystyrene foam plastic among all the treatments is 0.10m;the effect of heat preservation of the thinner brick is better than that of the thicker brick with the same thick polystyrene foam plastic;if the brick is thinner,the arrangement of materials plays an important role in the performance of heat preservation of wall.
