哈尔滨地处北方寒冷地区,冬季温室蔬菜生产,需要加温消耗大量能源,节能是温室能否大发展的关 键。哈尔滨市蔬菜研究所与建成机械厂合作,研制了一种太阳能为主要能源,保温为主要手段,以补温为辅的薄膜拱架式节能温室,其结构特点: (1)采光好 为了充分利用寒冷季节的光能,一方面加大温室采光面角度,另一方面又要降低温室的高度,故采取拱架式结构。哈尔滨春分时节太阳高度角为43°7′。该温室拱架大部分受光面角度为30°
Harbin is located in the northern cold area, winter greenhouse vegetable production, heating requires a lot of energy consumption, energy conservation is the key to the greenhouse’s development. Harbin Vegetable Research Institute and built Machinery Factory, developed a solar energy as the main energy source, insulation as the main means to supplement the supplemented film arch energy-saving greenhouse, its structural features: (1) good lighting in order to make full use of Light energy in the cold season, on the one hand to increase the greenhouse lighting angle, on the other hand, but also to reduce the height of the greenhouse, it takes the arch-type structure. Harbin vernal equinox solar elevation angle of 43 ° 7 ’. Most of the greenhouse light-receiving surface angle of 30 °
