基于Dest对办公建筑冷负荷的分析

Analysis of office building cooling load based on Dest software

基于Dest软件对办公建筑室内的冷负荷进行分析,通过计算不同的窗墙比、玻璃类型、墙的传热系数、屋顶传热系数、人员密度、灯光设备,得出室内冷负荷随着因素变化的曲线,并应用曲线分析负荷变化趋势。采用了最小二乘法,找出冷负荷随着不同因素变化的具体关系式。

The indoor cooling load within an office building was analysed based on Dest software. Corresponding relationships and tendency curves between indoor cooling load and some input parameters have been obtained by plotting the calculating results on coordinate graph, such input parameters including ： area ratio of window to outer wall, characteristics of window glass, coefficient of heat transfer of outer wall, coefficient of heat transfer of building roof, oecupying density of people, power of lighting and other electric appliances. Concrete mathematical relations of each corresponding relationships also have been obtained by a least-square fit method to supply reference guidance for designers and researchers.
