The concentrations of PM2.5 pollutants in three different air-conditioned microenvironment rooms were compared. The results that the PM2.5 concentration in descending order is highest non-air-conditioned room, centralized air-conditioned room, and split-type air-conditioned rooms. At the same time, the split-type air-conditioned room was tested using cigarette smoke. Changes in indoor PM2.5 pollutant concentration before and after the air conditioning system is turned on. It is proved that the split air conditioner has better control effect on PM2.5 pollution in the building, and the passive control strategy and active control strategy are proposed, which provides scientific guidance for further research on PM2.5 pollution control and prevention in the building.%建立了绿色建筑室内PM2. 5污染物浓度预测模型,实验对比了面积和装修大体一致的三个具有不同空调微环境房间的PM2. 5污染物浓度水平,表现出非空调房间最高、集中式空调房间其次,分体式空调房间最小的关系,同时利用香烟实验测试了分体式空调房间在空调系统开启前后室内PM2. 5污染物浓度变化情况,证明了分体式空调对建筑室内PM2. 5污染具有较好的控制效果,并提出了被动式控制策略和主动式控制策略,为进一步研究建筑室内PM2. 5污染控制和防治提供了科学指导.
