随着室内装修日益普遍和高档化,甲醛污染越来越严重,通风成为公认的保障人体舒适度和提高室内空气品质的可行性控制方法。在过渡季节进行通风实验,比较不同风量时甲醛浓度的降低效果及其变化规律。将甲醛浓度变化趋势分为两个主要阶段(速降阶段和渐变阶段),从而确定了同时满足卫生及节能要求的最佳换气次数(ACH)为1.5 h~(-1),并且建立了不同ACH条件下甲醛浓度的预测模型。
With the increasing popularity and high-end interior decoration, formaldehyde pollution is more serious, ventilation has become recognized as a guarantee of human comfort and indoor air quality improvement feasibility control methods. During the transitional season, ventilation experiments were conducted to compare the effect of reducing formaldehyde concentration and its variation during different air flow rates. The trend of formaldehyde concentration was divided into two main stages (descending phase and gradual phase), and the optimal number of exchange (ACH) meeting the hygienic and energy saving requirements was 1.5 h -1. Prediction model of formaldehyde concentration under different ACH conditions.
