双膜日光温室春季室内环境试验研究

为更加全面、科学地掌握双膜日光温室在春季室内内环境的变化规律,该文以双膜日光温室为研究对象,通过实时监测室内外环境,分析双膜日光温室在春季条件下典型日的室内热湿环境时变规律和特征。试验结果表明,春季条件下,晴天当日室内最大温升达到23.91℃,阴天当日室内最大温升仅为10.51℃,多云天当日室内最大温升18.97℃。晴天、多云天室内光照强度与温度变化趋势相似,而湿度呈现出与光照强度相反的变化规律。阴天湿度变化范围较小,最大湿度为91.41%,最低湿度为76.17%,日平均湿度为87.67%。

In order to more comprehensively and scientifically grasp the change rule of indoor environment of double-film solar greenhouse in spring season,this paper takes double-film solar greenhouse as the research object,analyzes the time-varying law and characteristics of indoor heat and humidity environment of double-film solar greenhouse under spring conditions on a typical day by real-time monitoring of indoor and outdoor environments.The results showed that under spring conditions,the maximum indoor temperature rise reached 23.91℃ on a sunny day,10.51℃on a cloudy day,and 18.97℃ on a cloudy day.The indoor light intensity and temperature change trends were similar on sunny and cloudy days,while humidity showed an opposite change pattern to light intensity.The range of humidity changes on cloudy days was small,with the maximum humidity of 91.41%,the minimum humidity of 76.17%,and the average daily humidity of 87.67%.
