Abstract |
This study investigated how the concentration effects in volatile organic compounds (VOCs) in newly built apartments could be effectively reduced in summer. Four types of ventilation experiments such as close-up, natural ventilation, mechanical ventilation, and temporary ventilation(mechanical ventilation + bake-out) have been carried out for seven days in four representative households. Each experiment was evaluated by measuring concentration reduction effect per day, along with its daily concentration rate. Measurement indexes were based on Benzene, Toluene, Ethylbenzene, Xylene, Styrene and Formaldehyde. Evaluation results were as follows. Using more than two plans simultaneously by dividing stages proved to be a more efficient way of reducing indoor VOCs than using only one plan. In addition, proper mixes or application of plans such as bake-out with temporary ventilation, bake-out with natural ventilation or with machine ventilation turned out to be a more efficient way of reducing concentration of indoor VOCs in the apartments. |
