摘要
针对高大空间公共建筑能耗居高不下、自然通风差的问题,以成都市某大型体育场馆为研究对象,通过实地测试调研,确定了成都市高大空间公共建筑室内热舒适温度区间为21.85℃~24.75℃。基于这一温度区间,采用数值模拟软件分析了不同自然通风策略下的建筑节能潜力。结果表明:成都市过渡季节可利用自然通风降温的时数达963小时,占过渡季总时长的26.23%,节能潜力显著。选取5月1日为典型日进行深入分析,发现当室外气温处于21.85℃~24.75℃范围内时,实施自然通风可有效改善室内热环境并显著降低空调负荷。研究可为成都市及夏热冬冷气候区高大空间公共建筑的自然通风设计提供参考。
Due to high energy consumption and poor natural ventilation performance in large-space public buildings,this study investigated the energy-saving potential of natural ventilation in such buildings in Chengdu.A large sports stadium in Chengdu was selected as the case study.Field measurements were conducted to determine the indoor thermal comfort temperature range,which was found to be 21.85℃ to 24.75℃.Based on this range,numerical simulation software was used to analyze the building’s energy-saving potential under different natural ventilation strategies.The results show that during transitional seasons,natural ventilation cooling can be used for approximately 963 hours,accounting for 26.23% of the total transitional period,indicating significant energy-saving potential.May 1st was selected as a typical day for detailed analysis.It was found that when the outdoor temperature falls within 21.85℃ to 24.75℃,natural ventilation can effectively improve the indoor thermal environment and significantly reduce air conditioning loads.This study provides a useful reference for the natural ventilation design of large-space public buildings in Chengdu and other regions with hot summer and cold winter climates.
