Abstract	High purity O$_{2}$ concentrated by the PSA-type O$_{2}$ separator was applied to a room ventilation system combined with CO$_{2}$ adsorption module to remove the indoor CO$_{2}$ for the indoor air quality. And then the room was occupied by several persons to breathe for the O$_{2}$ consumption and CO$_{2}$ generation. As a result, the indoor air quality was improved by the ventilation system combined with the O$_{2}$ supply and the CO$_{2}$ adsorption module. It was due to the fact that the CO$_{2}$ concentration was not steeply increased, but also even decreased and then the increasing rate of the O$_{2}$ concentration with the O$_{2}$ supply was simultaneously increased by the CO$_{2}$ removal despite the CO$_{2}$ generation and O$_{2}$ consumption with the four persons’ breathing. As a representative result, in the case of supplying the high purity O$_{2}$ of 30 L/min under using the CO$_{2}$ adsorption module, the best performance with the highest increasing rate of O$_{2}$ concentration and the lowest increasing rate of CO$_{2}$ concentration was obtained among the various cases, and then the increasing rates of CO$_{2}$ concentration and O$_{2}$ concentration were −2.3 ppm/min and 33.3%/min, respectively.
