以山西晋中地区日光温室作为研究对象,通过在温室内部布点测量温、湿度的试验和采用CFD进行数值模拟的方法,研究了冬季晴朗天气状况下,采用畦灌方式的日光温室在自然通风条件下内部湿度的分布规律。结果表明,冬季晴朗天气状况下,日光温室在08:00左右湿度达到最高值,14:00左右温度达到最高值;室内温、湿度显著负相关,温度每升高1℃,湿度降低3.31%;温室内部温度实测值与模拟值误差在±3℃以内,湿度实测值与模拟值误差在6.8%以内,整体拟合情况较好,证明了所建立模型的准确性;温室湿度在南北走向、东西走向变化不太明显,垂直方向上分层比较明显。太阳辐射所提供的热量足以维持温室所需,草帘的保温效果显著,无需对温室进行加温,但是温室夜间湿度较高,甚至接近饱和,需要对湿度进行控制。
