上海世博园部分建筑室内空调环境状况测试分析

Measurement Analysis on Indoor Air-conditioning Environment in Part of Buildings of Shanghai Expo Park

为了了解上海世博园建筑室内空调环境状况和行为节能情况,采用实测方法对上海世博园13栋建筑的夏季室内空调环境进行了测试分析。结果表明:一些被测建筑的夏季室内空气温度偏低,最低室温为21.7℃;对于南方湿热地区的剧场建筑,采用开敞式建筑方案不利于室内热舒适环境的营造和节能,且仅利用自然通风和蒸发冷却降温手段难以营造出满足人体基本热舒适性要求的室内环境;展厅观众人数快速增加时室温变化较大,但相对湿度变化较小;一些展馆外门常开,冷风渗漏现象比较严重,加强行为节能是展馆建筑节能设计和运行管理需要考虑的一个重要问题。

In order to understand the indoor air-conditioning environment and behavior energy-saving situation in part of buildings of Shanghai Expo Park,the measurement analysis of indoor air-conditioning environment of 13 buildings of Shanghai Expo Park in summer were carried out.The results shown that the indoor air temperatures of some tested buildings were lower in summer,the lowest value was of 21.7 ℃.Furthermore,for the theater buildings in wet and hot area in the south,the open building design scheme was unfavorable for indoor thermal comfort and building energy efficiency,and it was hard to create the indoor environment that meet the basic thermal comfort requirements only by means of natural ventilation and evaporation cooling.In addition,the rapid number increase of audiences in the exhibition hall would cause large room temperature variation,however,the variation of relative humidity was small.The door of some exhibition halls were normally open,the cold air leakage was serious,therefore,to strengthen behavior energy-saving was an important issue that should be considered during the building energy efficiency design and operation management.
