摘要
本文以某体育馆为研究对象,利用计算流体软件Airpak对馆中侧送下回的空调运行状况进行模拟。为了保证计算的准确性,进行网格无关性验证,同时在此基础上对原有的设计运行方案进行了数值模拟。通过对送风速度,送风角度以及观众上座率的研究,提出相应的优化方案。结果显示,当送风速度为4.5 m/s,送风角度为水平送风时为最优方案,最后,针对低上座率情况下(30%),通过增加送风温差(Δt=6.5℃),可提高室内人员舒适性。
This paper chooses a stadium of stratified air conditioning in summer as a research object. The commercial software Airpark was used to simulate the temperature distribution within the stadium. In order to ensure the accuracy of the simulation, the grid independence was executed. By analyzing the influence factors on the thermal comfort in the stadium, for instance, the air supply velocity, the air supply angle, the optimization solution for the relevant problems was proposed. The results show that the optimal air supply velocity and air supply angles are 4.5 m/s and 0° respectively.Considering the low occupancy（30%）, the thermal comfort of the indoor occupants can be improved by increasing the air supply temperature difference（Δt=6.5 ℃）.
