不同凹式墙体对温室蓄热性能的影响

采用3种凹式结构异质复合墙体，以平面墙体作为对照，研究不同凹式墙体对温室蓄热性能的影响，结果表明：3种凹式墙体在温室内近墙体表面30 cm处气温、墙体内深12 cm处温度均高于平面墙体；凹式墙体2（FW2）的凹口气温以及墙体内深12 cm热流通量的昼夜温差均表现为最大.筛选出凹式墙体2（FW2）是较理想的墙体，具有较好的蓄热性能.

Effects of different concave type structure wall on thermal performance in the greenhouse

Using three concave types structure heterogeneous composite walls, compared with plane wall, the influ- ence of different concave walls in the greenhouse on heat preservation and storage capability was studied. The result showed that the temperature close to the surface of the wall in 30 cm ,and in 12 cm deep inside the wall body area of three concave walls in the greenhouse were higher than the plane wall in respective; the temperature of notch of the concave type wall Ⅱ （FW2）,and day and night temperature difference of heat flux were maximum in 12 cm deep in side the wall. We screened out that concave type structure wall Ⅱ （FW2）which had the better heat storage perform- ance was the ideal wall.
