摘　　要：夏热冬冷地区气候条件复杂,夏季室外潮湿闷热,减少室外热量进入室内可以降低冷负荷;冬季室外潮湿寒冷,减少室内热量排入室外可以有效降低热负荷.本研究针对我国夏热冬冷地区的建筑墙体保温厚度进行优化,选取3种保温材料与4种墙体类型,运用度日数法计算冷热负荷,以能源成本与保温材料成本构成的总成本最低为目标,得到该目标下对应的最优经济保温厚度.The climate conditions in hot summer and cold winter areas are complex.In summer,it is humid and sultry outside,reducing outdoor heat into the room can greatly reduce the cooling load.In winter,it is humid and cold outside,reducing indoor heat discharge to outdoor can effectively reduce heating load.The study optimizes the thermal insulation thickness of building wall in hot summer and cold winter areas in China,selects three thermal insulation materials and four wall types,uses the degree days method to calculate the cooling and heating load,and takes the lowest total cost composed of energy cost and thermal insulation material cost as the goal to obtain the corresponding optimal economic insulation thickness under this goal.
