摘要
不同围护结构对应建筑物不同负荷。本文采用冷负荷系数法分析了四种围护结构类型在北京和上海两地区的空调冷负荷变化特征及保温墙体对节能率的贡献。结果表明:保温墙体较未保温墙体对应的空调冷负荷幅值有较大降低,而且,取得极值的时刻也不相同;不同的复合墙体所形成围护结构对应的逐时冷负荷变化趋势基本一致;同一类型围护结构在北京和上海对节能率的贡献差异很小,这为开发新型围护结构的跨区域推广应用提供了理论支持。
Different building envelopes correspond to different air-conditioning cooling load. The cooling load coefficient method is applied to analyze the air-conditioning cooling load and energy-saving rate resulting from four kinds of building envelopes in Beijing and Shanghai. The results indicate that the cooling load extreme value of the compound wall is lower than that of the uninsulated wall and the time corresponding to the extreme value is different. The cooling load varies with different compound walls at the same tendency but the difference is very small. The same insulated wall is contributed to energy-saving rate in Beijing is very close to Shanghai, which is advantage to extend the application region for new insulation wall.
