摘　　要：目的控制住宅内人造板材释放有害气体的排气能耗.方法以CO2替代甲醛作为污染物,经单送风、单排风、送风加排风等工况的实验测试及理论分析,模拟出不同工况下室内甲醛的质量浓度变化规律,进而测试分析其排气能耗.结果经过实验数据的处理,得出3种工况下CO2含量的变化率,进而得出甲醛质量浓度的变化规律.结论室内气体污染物的发生量为定值时,经3种工况均可降低室内污染物含量,但从排气能耗上分析,送风加排风方式的排气能耗最少,应优先选择.在等同于实验的条件下,若使住宅客厅内维持在甲醛一级空气品质状态,风机24 h常开时耗电量为0.72 kW.h/d.The aim of the paper is to analyse the energy consumption for contaminant removing efficiency of the formaldehyde of artificial plates in the residence. Taking CO2 as the typical pollutant, through the experimental test and theoretical analysis of air supply, air removing, ventilation conditions and so on, the contam- inant removing efficiency of the formaldehyde in the residence is simulated . On the basis of data analysis, the rate of the change of the density of CO2 under the well-ventilated condition is obtained, then the contaminant-formaldehyde＇s density curve in that condition is simulated. The conclusion is that, as to the contaminant in the residence, if the scattered amount is constant, it can decrease the contaminant density in all the conditions, and there is not obvious divergence on the contaminant removing efficiency. Under the same experimental conditions, if it maintains first class air quality condition of the formaldehyde in the residence, the minimal amount of electricity consumption ought to be 0.72 kW· h/d all the day.
