夏热冬冷地区高大公用建筑空调能耗特性分析

Constitutional Analysis of Air Conditioning Load of the Large-scale Building in Hot-summer and Cold-winter Region

利用Energyplus软件对夏热冬冷地区高大公用建筑空调能耗进行模拟分析,通过正交试验法研究空调能耗受负荷影响因子的影响情况,给出的影响因子排序为设备负荷>照明负荷>人员密度>室内设计温度>新风量>窗墙比>外窗传热系数>屋面传热系数>遮阳系数>外墙传热系数;进一步研究围护结构的影响因子与空调节能的关系,拟合得到节能率与围护结构影响因子间的回归方程,用于指导建筑空调节能设计及改造。

The energy consumption of air conditioning systems of large-scale building in Hot summer and cold winter region was caused by loads influence during satisfying indoor design parameters. The mainly aim of this paper is using Energyplus software to simulate the energy consumption of public air conditioning system, and then analyzing the impact factors with orthogonal test method. The order of impact factors should be equipment load, lighting load, personnel density, indoor design temperature, fresh air volume, window-wall radio, window heat transfer coefficient, roof heat transfer coefficient, shading coefficient and wall heat transfer coefficient. Moreover, the regression equation between energy saving rate and impact factors was fitted, which can provide theoretical basis for air conditioning system energy conservation.
