摘　　要：体形系数的大小可反映温室能耗的高低,因此求出不同形状的温室屋顶的体形系数,分析温室屋顶体形对体形系数的影响。根据极限体形系数分析不同形状的温室屋顶的节能潜力,确定最佳的节能温室屋顶形状、最佳节能长宽比和最佳节能宽高比,运用计算温室屋顶最佳节能体形的方法,分析各种体形与温室朝向和日辐射得热量的关系,可为温室的节能设计提供科学依据。As the building shape coefficient could reflect energy consumption of green house,the shape coefficient for various shape of green house roof was gained to analysis relation between the design shape and shape coefficient.Based on the bottom building shape coefficient to analysis energy-saving Potentiality for various shape of green house roof,the best energy –saving shape of green house roof,ratio of width and high and ratio of length and width are decided.The method to decide the optimum energy-saving building shape of green house roof is also given.Furthermore the relation among various building shape and orientation of green house and daily radiation heat energy is analyzed.It could provide scientific references for energy-saving design of green house.
