摘要
通过改变净化时间,PM2.5的初始浓度,风向以及房间的密闭性,获得在不同情况下净化器风量的数值和风量的变化规律。结果表明,各种外界环境因素的改变确实会影响净化器风量的大小。净化时间越短,所需要的风量也就越大。PM2.5的初始浓度和需求的风量之间是正线性关系。当室内的门窗的材料为单层木窗门,风向对净化器的选择不可忽略。同时,密封条件越好,所需求的净化器风量越小。
This research obtained the numerical value and change law of the inlet air flow rate by changing the time of purification, the initial concentration of PM2.5, the air direction and the tightness of the room.The results show that the change of the environmental factors can really affect the air flow rate of the air cleaners.The shorter purification time, the greater the amount of air required.Between the initial concentration of PM2.5 and demand volume is positive linear relationship.When the indoor doors and windows of the material for single door window and doors, the direction of the choice of the cleaners can not be ignored. At the same time, the better the sealing condition, the smaller air quantity of the cleaner is required.
