空净一体机和空气净化器联合系统对PM_(2.5)净化时间的对比研究

Comparative Study of PM_(2.5) Purification Time By Combined System of Air Conditioner with Purification and Air Purifier

为了对比卡式空净一体机和空气净化器联合系统对PM_(2.5)净化效果的区别,本研究以空净一体机联合换气系统和空气净化器+空调联合换气系统为研究对象,用CFD软件建立模型后用实测数据验证了模拟的准确性,并通过拓展模拟分析两种联合运行系统在相同条件下将室内PM_(2.5)质量浓度净化至低于35μg/m~3的相对时长。研究结果表明,在空净一体机和空气净化器的送风量差别不大的情况下,良好的气流组织使空净一体机联合系统能在更短的时间内净化PM_(2.5)。

To contrast the difference between the PM_(2.5) purification effect of the card-type air conditioner with purification and air purifier combined system,the study takes the air conditioner with purification combined ventilation system and the air purifier+air conditioner combined ventilation system as the object of study,and the accuracy of the simulation was verified with measured data after modeling with CFD software,and analyzes the two kinds of jointly operated systems under the same conditions by expanding the simulation to purify the indoor PM_(2.5) mass concentration to less than 35μg/m under the same conditions.The results show that the good airflow organization enables the combined system of air conditioner with purification to purify PM_(2.5) in a shorter time under the condition that the difference in air supply volume between the air conditioner with purification and air purifier is not large.
