摘要：

优化墙体结构并最大限度地发挥墙体的蓄热保温性能,对提升日光温室作物的生产水平具有重要意义。现以3种不同北墙体结构(24cm砖墙+50cm黄土+24cm砖墙即砖土结构、24cm砖墙+50cm灰煤渣+24cm砖墙即砖煤结构、37cm砖墙+10cm苯板即砖苯结构)日光温室为研究对象,通过分析典型天气下气温、北墙传热量、北墙内表面温度等指标的变化规律以及不同结构北墙的温度时空分布特点,初步评价了不同北墙体结构日光温室的保温性能差异。结果表明:砖苯结构北墙体的瞬时吸热散热能力较强,但其蓄放热持久性较差,而砖土结构复合北墙体的瞬时吸热、连续蓄热保温性较好。整体而言,砖土北墙结构日光温室在晋中地区具有较好的推广价值。

摘要：

Optimizing the wall structure and exerting its performance of heat preservation to greatest extent,is significant to improve the technologies in solar greenhouse crop production.Three solar greenhouses with different north wall structures,including brick-loess wall(a layer of 50cm loesses between two 24cm bricks),brick-cinder wall(a layer of 50cm cinders between two 24cm bricks)and brick-polystyrene wall(the inner 37cm bricks and the outer 10cm polystyrene boards),were used as research subjects in this study.The change rules of the indoor air temperature,the heat transfer capacity and the inner surface temperature of north-wall were analyzed under typical weather days.And the spatial and temporal distribution features of temperatures in different north walls were also investigated.Differences of thermal insulating properties of the three solar greenhouses were preliminary evaluated.The results showed that the brick-polystyrene north-wall had the better instantaneous heat absorption and dissipation capacities,while its heat-storage and discharge persistence was poor.Moreover,the brick-loess north wall had the better instantaneous heat absorption and continuous thermal insulating integrated properties.Overall,the solar greenhouse with brick-loess north wall had more extensive spreading values in Jinzhong area.
