| 摘 要： | 分析了目前空调系统新风和回风对室内空气品质的影响，认为室内污染的不断增加是室内品质变坏的主要原因；新风的质量直接影响室内空气品质；回风是室内空气的二次污染源，导出了回风对室内空气污染的理论计算公式，文中认为新风率是20%能明显提高室内空气品质。

| Abstract: | This paper analyses that fresh air and return air efet IAQ in air-conditioning system at present.The prime reason of IAQ becoming worse is the source of increasing indoor contaminant.The fresh air quality directly affects IAQ.The return air always pollutes the IAQ again.On this base,the author educes the theoretical formula about it and the fresh air ratio in air-conditioning system is 20%,which obviously improves IAQ. |
