The building atrium is a large space formed by integrating various functions. It runs through multiple floors and is directly or indirectly connected with each floor. In the atrium, people can not only enjoy the air quality of the interior space but also create an open and natural environment characteristic of the outdoor space. In this paper, a winding corridor atrium is the research object, using CFD simulation software to establish a mathematical model. The temperature field, velocity field, and PMV-PPD of the atrium under various working conditions were studied by numerical simulation method, and the thermal comfort of the working area at the bottom of the atrium and the corridor area of each floor were analyzed emphatically. The building atrium is set up in two forms: the upper part is airtight and the upper part is not airtight. Through theoretical analysis and comparison of simulation results, it is concluded that the non-enclosed atrium will help to improve the thermal comfort of the top, and at the same time aggravate the phenomenon of low temperature in the working area at the bottom of the atrium.
