空净一体机送风速度、角度变化对净化能力的影响研究

Study on the Effect of Air Supply Speed and Angle Change on Purification Capacity of Air Conditioner with Purification

为了研究在空净一体机和换气系统联合运行时空净一体机的送风速度、角度变化时系统对PM2.5和CO_(2)净化能力的影响,本文通过实验研究验证模拟的准确性,再通过利用Fluent软件进行拓展模拟,最后得出空净一体机送风角度变化的影响大于送风速度的结论,并给出在室内同时有PM2.5和CO_(2)净化需求时宜采用大角度、CO_(2)浓度较低但PM2.5浓度较高时采用中角度、两者浓度都较低时采用小角度运行的建议。

In order to study the influence of the air supply speed and angle of the air conditioner with purification on PM2.5 and CO_(2)purification capacity when the air conditioner with purification and the ventilation system operate together,this paper verifies the accuracy of the simulation through experimental research,and then expands the simulation by using Fluent software,and finally concludes that the influence of the air supply angle change of the air conditioner with purification is greater than the air supply speed,and gives the suggestion that a large angle is preferred when both PM2.5 and CO_(2)purification are required indoors,a medium angle is preferred when CO_(2)concentration is low but PM2.5 concentration is high,and a small angle is preferred when both concentrations are low.
