摘　　要：采用建筑空调模拟软件DeST对我国南北6城市不同传热系数外墙的办公建筑的空调冷热负荷进行模拟计算,计算和分析的结果表明,冬季,外墙的传热系数越小,空调热负荷越小,建筑越节能;夏季的情况与冬季不同,传热系数越小,空调冷负荷越大,建筑反而不节能。室内设定温度升高或降低,空调负荷并不是按相同比例变化,因此,存在满足人体热舒适的情况下最佳室内设定温度。室外气象条件对建筑能耗节能率的影响程度在夏热冬暖地区超过了围护结构的传热系数。Using the simulating software DeST to calculate the air conditioning cool and heat loads of office buildings with different heat transmission coefficient envelope in six cities of China.The results show that the lower the heat transmission coefficient of building envelope,the lower the air conditioning loads,the better energy saving of building in winter.Inverse,the lower the heat transmission coefficient of building envelope,the higher the air conditioning loads,the worse energy saving of building in summer.The air conditioning loads varied with different proportion when the indoor set temperature was higher or lower 1℃.So there exists an optimized temperature setting for satisfaction human.The influence of the outdoor meteorological parameter was greater than the envelope heat transmission coefficient to building fractional energy saving.
