Indoor chemical reaction is one important factor impacting indoor air quality. Considering the influence of chemical reaction between ozone and human body surface, it is the premise for controlling ozone pollution and improving indoor air quality by obtaining the features of indoor combined pollution induced by ozone. Firstly, based on the method of experimental research, this study analyzed the variation characteristics of ozone and total volatile organic compounds’ pollution under three ventilation modes of mixing, displacement, and floor orifice. Secondly, by means of numerical simulation, this study focused on the chemical reaction between ozone (O3) and terpenes under the condition of residential variable density and analyzed the unsteady change characteristics of the concentration of air chemical reaction products under the conditions of mixed and displacement ventilation modes and different air changes. The results show that the concentration of pollutants is negatively correlated with the number of air changes under the same ventilation mode. At the same time, the concentration of total volatile organic compounds (TVOC) follows the ozone concentration obviously. In addition, the amount of O3 in the room determines the process and degree of the whole air chemical reaction. The concentration of reaction product under mixed ventilation is lower than that under displacement ventilation.
