摘要
简单介绍了诱导通风空调系统的工作原理和在建筑空调中的优势,并以某一办公室为研究对象,采用数值计算的方法,利用Fluent和Airpak软件对室内的气流组织和空气龄进行模拟,并利用PPV-PPD对室内的舒适度作出综合评价,并做了深入的分析研究。结果表明,诱导通风较高的通风效率有效地排除室内有害气体污染物,PPV-PPD图显示室内的热舒适性良好。
The work principle and advantages of inducted ventilation in building air conditioning are introduced briefly. Regarding one office as the study object, the numerical analysis software Fluent and Airpak is applied to conduct a numerical simulation for indoor air distribution and air age, a comprehensive evaluation is conducted by indoor thermal comfort parameters PPV- PPD. The results show that indoor harmful air pollutants could be excluded effectively by inducted ventilation, the ventilation efficiency is higher and PPV- PPD figure shows that the indoor thermal comfort is good.
