中文摘要：
本文利用Airpak3.0软件对某典型住宅建筑在新风机不同送风量作用下室内的流场、空气龄及二氧化碳浓度进行数值模拟与分析,根据模拟分析结果总结出新风机运行改进方法。研究结果表明：新风机的安装位置、新风量的大小、送风的方向成为影响室内流场分布的主要因素;新风机可以依据室内CO2实际浓度的检测结果来对新风量加以实时调节和送风方案控制,避免新风量不足以及因新风量过多造成空调能耗增加的问题。
英文摘要：
In this paper,Airpak3. 0 software was employed to make numerical simulation and analysis on the indoor flow field,air age and carbon dioxide concentration of a typical residential building under different air supply rates by the fresh air exchanger,and the improvement methods for the operation of the fresh air exchanger was summarized based on the simulation results. The results showed that the installation location,the new air volume and the direction of air supply were the main factors that influenced the distribution of the indoor flow field.Besides,the fresh air exchanger was able to make real-time adjustment and air supply control according to the detection result of the actual indoor CO2 concentration,thus avoiding the problem of lack of new air volume and the increase in energy consumption due to excessive new air volume.
