摘要
以双膜日光温室为研究对象,通过测试分析了双膜日光温室在连续阴天条件下室内热湿环境时变规律和空间分布.结果表明:连续阴天条件下当日最高温度和最低温度均较前一天有所下降,但温室内最低温度为9.266 ℃.双膜日光温室室内不同位置温湿度略有差异,平均温度沿温室跨度方向由南至北逐渐增大,沿长度方向由东向西逐渐降低,沿高度方向由低到高逐渐降低,相对湿度呈现与温度变化规律相反的特点.研究结果可进一步明确双膜日光温室在不同环境条件下的室内热湿环境,为双膜日光温室实现室内环境精准调控提供参考数据.
Abstract
In this paper,the time-varying pattern and spatial distribution of indoor heat and humidity environment in double-film solar greenhouses under continuous cloudy conditions were analyzed through tests with double-film solar greenhouses as the research object.The test results showed that the maximum and minimum tempera-tures of the day under continuous cloudy conditions decreased compared with the previous day,but the minimum temperature in the greenhouse was 9.266 ℃.The temperature and humidity of different locations in the double-film solar greenhouse were slightly different,and the average temperature gradually increased from south to north a-long the greenhouse span direction,gradually decreased from east to west along the length direction,and gradually decreased from low to high along the height direction.The relative humidity showed the characteristics of the op-posite pattern of change with the temperature.The results of the study can further clarify the indoor heat and hu-midity environment of double-film solar greenhouses under different environmental conditions,and provide a ref-erence data for the realization of precise indoor environmental regulation of double-film solar greenhouses.
