The Indoor Thermal Environment Simulation and Analysis of an Emporium With Atrium

In most emporiums with atrium the phenomena of vertical temperature nonuniformity are very severe, especially in winter. In this paper with an example of emporium with atrium the actual data are measured and by using the method of CFD simulation the indoor thermal environment of the atrium and surrounding area are simulated. The three-dimensional flow fields are studied, the temperature and velocity fields under different air flow organization modes are gained, the effect of the atrium to the whole building is discussed and the corresponding correction method to the indoor space loads, especially the space loads in the upper and lower stories are proposed. The results above will be good references for the design of the emporiums with atrium. The use of the correction method will help to obtain a comfortable and stable indoor thermal environment, and also will be good to the building energy conservation.
