基于室内颗粒物质量平衡方程，建立了通风过滤空调系统的数学模型，对不同的通风系统以及不同粒径下的I／O比进行了理论研究。通过数值计算表明，过滤器效率对机械通风系统的I／O比影响显著；对于自然通风系统，当换气次数由1h-1增加至6h-1，I／O比变化迅速，继续增大换气次数，则I／O比趋于平缓。

Using mass balance equation to build a mathematical calculation mode, analyze the influence of ventilation and diameter parameters to I/O. The results show that filter efficiency' s influence on I/O is significant for mechanical ventilation; For natural ventilation system, when the air change rate increases from 1h-1 to 6h-1, the I/O value changes rapidly, if continue to increase the air change rate, and then appears a gentle decline.
