Abstract

Abstract

To realize all-year-round air purification together with strengthening indoor ventilation in indoor environment, this study has numerically proposed a solar photocatalytic ventilation wall system coupling with hybrid ventilation and further investigated the diffusion characteristics of pollutants in winter and summer. Based on computational fluid dynamics, key parameters of solar radiation intensity and initial velocity have been comprehensively studied to analyze the effects on system pollutant removal rate and comprehensive evaluation index. The simulated results showed that the collaborative model for pollutant removal and hybrid ventilation is reliable and feasible. Especially, the comprehensive evaluation index for winter mode gradually increased from 0.00 to 1.00 with an increase in radiation intensity, while the summer model showed a negative correlation from 0.50 to 0.37. Increasing the initial velocity caused the comprehensive evaluation index of the winter model to decrease by up to 97%, while that of the summer model initially increased, then decreased and finally increased again. The adjustment of the external heat flow input and initial velocity has positive significance for promoting the removal of indoor pollutants.
