摘要
为了优化冬季温室环境,运用CFD模拟技术,分析了冬季某温室的气流组织情况,指出了冬季温室存在的弊端:由于冬季温室不通风,温室内气流停滞,二氧化碳浓度及温度分布不均匀,无法为植物生长提供良好的生长环境。为此,根据温室的实际情况,提出了通过用内循环风扇来优化温室内气流组织的方法,使温室内气体流动,形成良好的气流组织,改善植物的生长环境,达到提高温室产量的目的。
In order to optimize the environment of greenhouse in winter, using the CFD simulation technology to analyses the air distribution in a greenhouse. Thus conclude the disadvantages in the greenhouse, they are： because of the greenhouse is nonventillated , the gas stratification and the Carbon dioxide and temperature is norrnniformity. It is not a good growing environment for plants. According to the actual situation of the greenhouse , put forward the method that optimize the air distribution by circulation fan, aim at to through the air flow to form a good air distribution and improve the growing environment of plants. Thus to achieve the purpose of increase the production of greenhouse.
