                                简要介绍日光温室结构参数的确定

                                2021-8-8??????浏览:

                                日光温室结构参数主要包括跨度,高度、前后屋面角度、墙体和后屋面厚度、后屋面水平投影长度等。结构参数的确定应重点考虑采光、保温、作物生育和人工作业空间等问题。


                                温室墙体和后屋面的厚度:日光温室的墙体和后屋面既可以起到承重作用,又可起到保温蓄热作用。因此,在设计建造日光温室墙体和后屋面时,除了要注意考虑承重强度外,还要考虑建筑材料的导热、蓄热系数和足够的厚度。


                                后屋面水平投影长度:由于温室后屋面常采用导热率低的不透明材料,而且较厚,因此其传热系数远比前屋面小。后屋面越长,晚间保温效果越好。但屋面过长,太阳高度角度较大时,就会出现遮光现象,而使温室后部出现大面积阴影,影响作物的生长发育。
