摘 要: 运用计算流体力学(computational fluid dynamics,CFD)模拟分析,结合实际情况研究民用建筑及工业建筑高大空间通风方式及室内环境控制方法。民用建筑是利用热压通风,对某中庭自然通风条件下进行室内温差CFD模拟分析,其温度场分布具有垂直梯度;对某门厅置换通风条件下进行室内温差CFD模拟分析,其温度在室内分层明显,且活动区达到人体舒适要求。工业建筑则是以控制污染物为目的,对实际建筑分别以吹吸式通风和置换通风进行局部污染物控制模拟计算,在送风量相等、污染物释放强度相等的前提下,两者都有较好的作用。
关 键 词: 通风与空调工程;高大空间;通风方式;垂直温度梯度

Abstract: Combining with actual situation, ventilation and indoor environmental control methods of the civil and industrial construction with large space were studied by computational fluid dynamics (CFD) in this paper. In natural ventilated civil construction, stack effect was driven force. Under the condition of natural ventilation, indoor temperature distribution in an atrium was analyzed with CFD simulation. And the results showed that there were vertical temperature gradients in the atrium. In the same way, CFD simulation was done in a vestibule for the same purpose under displacement ventilation condition. The results conducted that there was obvious temperature stratification in the interior, and human thermal comfort requirements were met in occupied zone. In the industrial buildings, main purpose of ventilation is to control pollutants. In the actual buildings installed with push-pull ventilation or displacement ventilation system, simulation calculations were done to check the system’s effects to the local pollution control. The results indicated that if the air volume and the release intensity of the pollutants were the same in the two systems, pollutions could be both effectively controlled.
Key words: ventilation and air conditioning engineering; large space; ventilation method; vertical temperature gradients
