摘要
针对一次回风空调系统室内颗粒状污染物的浓度场分布情况,采用数值仿真的方法,结合过滤器的临界过滤效率,得到当过滤器的组合效率不同时,增大新风比对室内颗粒状污染物的稀释效果也不同。在实际空调系统设计时,应结合经济运行,选择合适的过滤器组合及新风比。
This paper focuses on the concentration of particulate pollutants among the indoor air in the air conditioning system with return air. From the result of the numerical simulation considering the critical combination of filtration efficiency, we can get the conclusion that, for air conditioning systems with different combination of filter efficiency, the significance of increasing fresh air ratio to dilute the particulate pollutants is different. So when we design air-conditioning system with return air, we should select appropriate combination of filters and fresh air ratio, and considering economic operation meanwhile.
