摘要(Abstract):

使用用户自定义函数(UDFs)定义空调器与空气净化器进出口特性,模拟研究了夏季典型空调房间中组合使用空调器与空气净化器以及单独使用净化型空调2种情况下的流场特性和污染物浓度分布。模拟结果表明:相同空调风量下,组合使用空调器与净化器比单独使用净化型空调效果更好;空调的送风角度对室内空气流场和污染物去除有一定影响,壁挂式空调对送风角度更为敏感;净化型空调采用下送下回的气流组织形式能更好地减少污染物的扩散;净化型空调的循环通风量并不是越大越好,当循环通风量达到500m~3/h后,其对甲醛净化能力的提升幅度减小。
User-defined function(UDFs) was used to define the inlet and outlet characteristics of air conditioner and air cleaner,the characteristics of flow field and pollutant concentration distribution under two different conditions:combined use of air conditioner and air purifier as well as single use of clean air conditioner in the typical summer room with air conditioner are simulated. The simulation results indicate that:Under the same air conditioning air volume,the combined use of air conditioner and air cleaner is better than single use purify air conditioner. The air supply angle of air conditioner has some influence on indoor air flow field and pollutant removal,and the wall mounted air conditioner is more sensitive to the air supply angle. The clean air conditioner with the bottom supply and bottom return mode could reduce the diffusion of pollutants effectively. Circulating ventilation volume of the purify air-conditioner is not as large as possible,when the amount of circulating ventilation reaches 500 m~3/h,the increase of purification capacity is getting smaller and smaller.
