日光温室建筑参数对室内温度环境的影响

Relationship Between Structural Parameters of Solar Greenhouse and inside Temperature

温室建筑参数对室内的环境有直接影响。通过对具有不同朝向、墙体高度、后坡仰角的单斜面日光温室室内温度环境的对比实验 ,探讨了温室建筑参数对室内温度环境的影响。测试结果表明 :晴天时 ,南偏西温室室内夜间温度高于正南及南偏东温室 ;但阴天时 ,温室朝向对室内温度环境无明显影响 ;在朝向正南 ,保持后坡仰角、跨度、后坡长度不变的情况下 ,随墙体高度的增加 ,夜间室内温度增加 ;保持后墙高度、跨度、后坡长度不变的情况下 ,随后坡仰角的增加 。

Building parameters of solar greenhouse affect environment inside greenhouse directly.The relationship beˉtween building parameters and inside temperature was studied by testing the single slope greenhouses with different orientations,heights of wall and angles of north slope.The results showed that,in sunny day,temperature in greenˉhouse with south by west is higher than that of greenhouse with right south or south by east;in a cloudy day,the temperature has nothing to do with the orientation.The results also showed that under the condition that the angle of north slope,span and length of north slope are constant,temperature inside greenhouse southward rises with the increase of height of the wall,and that with height of wall,span and length of north slope are constant,temperaˉture inside greenhouse southward has little change with the increase of the angle of north slope.
