摘要
分析了建筑外墙保温层厚度对加热冷却负荷的影响,对广州某酒店建筑采用Energy Plus软件计算酒店空调系统两种用能模式(全天运行和夜间运行)下的最优能耗保温厚度。结果表明,夜间运行模式下增加保温层厚度会增加冷却能耗,酒店建筑的供冷能耗要从"增加保温层厚度降低冷却能耗"转变为"增加保温层厚度增加冷却能耗"。空调温度26℃夜间运行模式下采用挤塑聚苯板(XPS)保温材料得到的最优能耗保温厚度4.1 cm。
The influence of building external wall＇s insulation thickness on heating and cooling load was analyzed. The optimum energy consumption thickness under two kinds of energy use patterns （run a whole day and night operation） for a hotel air conditioning system was calculated employ Energyplus software for Guangzhou located in hot summer and warm winter zone. The results demonstrate that there are instances where adding insulation thickness will increase the cooling energy consumption for night operation mode. The cooling requirement of the hotel building switches from an ＂adding insulation thickness decreases the cooling energy consumption＂ to an ＂adding insulation thickness increases the cooling energy consumption＂. Using extruded polystyrene board （XPS） as insulation material, the optimum energy consumption insulation thickness is 4.1 cm with air conditioning temperature is 26 ℃ and night operation mode.
