摘　　要：针对建筑室内环境模拟中的耦合特点,同时考虑建筑围护结构中的导热与室内空气的对流问题,详细分析了建筑室内空气流动及建筑围护结构传热过程的物理数学描述方法,对热流耦合特性的数值计算方法做了探讨;建立了宏观描述和微观描述的耦合模拟模型,同时对这两种耦合模型的优缺点做了定性讨论;最后利用CFD软件把建筑围护结构传热与室内流动作为整体进行了微观耦合的数值模拟。结果表明,微观耦合模型并不适合室内环境的通风与热耦合问题的计算,有待于宏观耦合模型的研究及实用高效热耦合分析软件的进一步开发。In order to show the coupling characteristic of building indoor environmental simulation, authors considered both building structures＇ heat transfer problem and air flow problem in the room. The detailed physical and mathematical description methods of building indoor environment were analyzed, and its computational method was discussed. The coupling models and simulation method of the macro-coupling and micro-coupling models were introduced. Furthermore, the merits and demerits of two models were analyzed. Lastly as the fulfillment procedure of the micro-coupling model, CFD was used to simulate the building indoor environment, while the calculation range was extended to the exterior surface of wall. The results show that micro-coupling model is not fit for simulating the heat transfer and air flow coupling problem in the building, and there is urgeently needing to develop an effective heat coupling analysis software based on macro-coupling model.
