The Research of Air Quality and Its Control in Air-conditioning Room

Zou Shenghua,Li Qiang,Yu Meichun,Yang Jinghua

Strategic Study of CAE 2007, Volume 9, Issue 3, Pages 82-86

Abstract:

The influence of outside air and return air on the IAQ in a typi calair-conditioning room is analyzed.It is proved that the increasing indoor contamination makes the IAQ worse, the outside air quality hasa direct effect on the IAQ, and the return air produces secondary pollutes.The theoretical formula about outside air, return air and the contaminant is induced.
