Simulation of Indoor Airflow Organisation in Tall Building Space
This article takes the high-rise lobby of an office building as the analysis object,and uses CFD numerical simulation method to analyze the indoor temperature and wind speed distribution under design and comparison conditions.The results show that in summer,the vertical temperature gradient and velocity gradient are relatively small,resulting in better personnel comfort;In winter,due to the effect of the hot water radiation heating system,the vertical temperature gradient is relatively small,and the temperature distribution in the entire space is relatively uniform.Under the premise of meeting thermal comfort,the summer air supply temperature can be selected as 18 ℃,and the winter air supply temperature can be selected as 28 ℃.It can also be considered to turn on floor heating when the outdoor climate conditions are relatively harsh,in order to save energy.The research results of this article can provide a certain reference for the design and optimization of radiation heating and air conditioning supply systems in tall spaces.
