空调系统送风方式影响空气污染物质量浓度分布实测研究

Influence of Air Supply Mode of Air-Conditioning System on Pollutant Concentration and Distribution

如果没有分析微生物气溶胶的传播机理,导致空调系统的空气污染物质量浓度分布研究结果不准确,对此,提出空调系统送风方式影响空气污染物质量浓度分布实测研究方法,根据分析结果构建房间物理模型,在房间物理模型的基础上研究空气污染物质量浓度分布受空调系统送风方式、送风量和污染源散发质量浓度的影响,研究结果表明,采用顶送侧回的空调系统送风方式,增加空调系统送风速度在一定风速范围内可以降低污染物在室内的质量浓度,提高了研究结果的准确率。

Insufficient analyze of propagation mechanism of microbial aerosol will lead to inaccurate research results of air pollutant mass concentration distribution in air conditioning system.Therefore,the research method of air pollutant mass concentration distribution affected by air supply mode of air conditioning system is proposed.According to the analysis results,the room physical model is constructed,and the air pollutant mass concentration distribution is studied on the basis of the room physical model.Affected by the air supply mode of air conditioning system,the air supply volume and the mass concentration of pollutant emission is studied.The research results show that the air supply mode of top supply side return air conditioning system can reduce the indoor mass concentration of pollutants and improve the accuracy of the research results by increasing the air supply speed of air conditioning system within a certain wind speed range.
