Experimental Study on Indoor Dynamic Heat and Humidity Environment of Double-Film Solar Greenhouse
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.
