Experimental study of personal exposure to pollutants released at floor level: floor heating vs air heating
The performance of floor heating and air heating combined with mechanical ventilation are significantly different from perspective of air distribution and contaminant dispersion. The aim of this study was to evaluate ventilation effectiveness and personal exposure of the occupants to airborne pollutants emitted at floor level in rooms with air heating and floor heating systems combined with mixing ventilation. Two air distribution methods were experimentally tested in the full-scale chamber at the air change rate of 2 ach. The pollutant concentration was monitored at five points by using volatile organic compounds (VOC) sensors. Three positions of the heated dummy were used to estimate the effects of convection generated by the occupant as well as personal exposure. The results of the experiments showed that the heating type did not affect ventilation effectiveness significantly. However, personal exposure registered in cases with floor heating was lower by 31% in average, compared to air heating cases.
