Abstract：Taking the enclosed atrium of an office building in Beijing as the research object,CFD numerical simulation method is used to analyze the temperature and velocity distribution in winter and summer.The results indicate that overheating occurs under natural ventilation conditions in summer;After turning on the air conditioning and mechanical ventilation,the average temperature in the personnel activity area is low,and energy-saving can be achieved by reducing the air supply volume of the air conditioning.In winter,the top exhaust is directly sent back to the atrium through the heat recovery port,which can meet the thermal comfort requirements of personnel in the activity area.This study provides useful reference for the design and operation of layered air conditioning systems in the atrium of office buildings in northern China.
