摘要
应用CFD方法分析了空调房间内5种气流组织条件下污染物的浓度分布情况,研究结果表明,孔板送风形式更有利于污染物的消除。针对孔板送风模型,对不同新风量、不同污染源散发量等工况进行了数值模拟,得出了在这些工况下污染物浓度的分布特性和变化规律,从控制室内污染物的角度为空调系统的设计提供参考。
By application of CFD, the concentration distribution of pollutants under the conditions of the five kinds of airflow organizations in the air-condition room was analyzed. The results show that the form of the orifice plate air supply is more conducive to the elimination of pollutants. As for the model of orifice plate air supply, the author made numerical simulation on the conditions of the different air quantity and the different emissions of pollution source. The author has obtained the distribution characteristics of pollutant concentration and the change of regular pattern, expecting to provide reference for the design of air-conditioning system from the perspective of the control over the indoor pollutants.
