摘    要:为改善老旧黏土砖墙的保温蓄热性能,使用发泡水泥对黏土砖墙进行加厚并进行了试验测试。对照温室黏土砖墙由120 mm黏土砖+100 mm聚苯板+240 mm黏土砖(从室内至室外)构成,试验温室结构、管理与对照温室相同,仅北墙采用200 mm 的发泡水泥对原有黏土砖墙进行了加厚(简称为“改造砖墙”)。通过对比分析2温室墙体在典型晴天和阴天内的温度变化,表明:在晴天夜间,黏土砖墙和改造砖墙外表面温度比室外气温分别高(2.8±0.9)和(0.8±0.2)℃,黏土砖墙和改造砖墙内表面温度比室内气温分别高(1.5±0.5)和(2.4±0.2)℃。在阴天,黏土砖墙全天内表面温度全天低于室内气温,而改造砖墙内表面温度在17:30-次日08:00期间较室内气温高(0.3±0.2)℃。因此,采用发泡水泥加厚黏土砖墙不仅可减少墙体热损失,还能增加墙体夜间散热量。

关 键 词:温室  温度  热损失  发泡水泥  黏土砖墙  保温蓄热
