摘  要：
【目的】适当空气流动对植物的生长非常重要,研究新型对流循环蓄热墙体构造对日光温室中所形成的气流影响。【方法】通过现场试验,在距离墙体0.3 m、0.6 m、0.9 m位置对上下两排通气孔高度处的气流速度和温度等进行了测试,并在测试的基础上,通过FLUENT软件,对包括作物在内空间的气流分布进行模拟分析。【结果】该墙体构造所形成的循环气流,可以在一定程度上扰动室内空气,进而在温室内走道和作物栽培行间等位置形成气流,其中温室跨中栽培行间的下部平均气流速度可达0.25 m/s。【结论】对流循环蓄热墙体自身的对流作用,可对日光温室冬季封闭栽培条件下的气流环境有一定的改善作用。

摘  要：
【Objective】Proper airflow is very important for the plant growth; this study aims to explore the airflow effect caused by the new convective circulation thermal storage wall structure in Chinese solar greenhouse.【Method】Based on field experiment method,points of wind speed and temperature were tests from the back wall 0. 3 m,0. 6 m and 0. 9 m on the bottom two rows vent holes height. And on a test basis,the air distribution simulation analysis including crop space was carried out by the Fluent software.【Result】The result of measurement and simulation analysis showed that recycle stream,which was formed by wall structure,could be disturbing indoor airflow to some extents,thereby forming airflow in the aisles between drop cultivation rows and other locations. The measuring points average wind speed at the bottom cultivated rows middle position was of up to 0. 25 m / s.【Conclusion】The self- convection of the new convective circulation and thermal storage wall have some improvement action for the solar greenhouse airflow environment in the winter closed cultivation conditions.
