摘要：室外PM2.5可通过新风及国护结构缝隙渗透至室内，室外PM2.5较高时尤为明显，结果导致室内空气中的PM2.5浓度上升。为了研究空调形式对室内外PM2.5浓度相关性的影响，在 2015年夏季对重庆某办公建筑中采用不同空调形式的室内外PM2.5浓度进行了实测。实测结果发现：集中式空调、分体式空调和非空调房间室内外PM2.5浓度比变化范围分别为0.59～0.76、 0.47~～0.76、0.71～0.91。室内外PM2.5浓度相关性系数的排序为：集中式空调环境（0.94)>非空调环境（0.92)>分体式空调环境（0.77），研究结果表明，办公建筑的空调形式，对室内外PM2.5 浓度的相关性有影响。

Abstract: Outdoor PM2. 5 could penetrate through fresh air and the wall gap into the room especially when outdoor PM2. 5 is particularly high, which lead to the rapid rise in the indoor PM2. 5 concentration. To determine the influence of the air conditioning system form on the indoor and outdoor PM2.5 concentration, the PM2. 5 concentration in the room with different air conditioning forms is measured in the summer of 2o15, which is in an office building in Chongqing . The measured results show that: the range of the indoor and outdoor PM2. 5 concentration ratio is 0. 59~0. 76, 0. 47~0. 76, and 0. 71 ~0. 91, respectively when the air conditioning system is . The relationship of indoor and outdoor PM2. 5 concentration correlation coefficient is centralized air conditioning environment （o. 94) > non air conditioning environment (0. 92) > decentralized air conditioning environment (0. 77). The results show that air conditioning form in office building has the effect of on indoor PM2. 5 concentration.
