Abstract:
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.
