摘　　要：会展建筑室内展厅具有空间高大、人员密度大且停留时间长、对室内环境的舒适度要求高的特点。结合这些特点及实际工程设计案例,本文对展厅大空间进行CFD模拟预测,通过分析展厅人员活动区的温度场、速度场、PMV、PPD的分布规律,以验证展馆空调通风系统送排风方式的可靠性。研究结果表明在高大空间区域设置分层空调以及在空间顶部设置机械排风系统,对室内环境的热舒适性均有较好的作用。本文对相类似的会展建筑设计有一定的指导意义。The indoor room of exhibition buildings has a large space,high and long-lasting population density,and high requirement of comfort level of indoor environment.Based on these characteristics and practical engineering design cases,this paper performs CFD simulation and prediction on the large space of exhibition room by analyzing the distribution of temperature field,velocity field,PMV,and PPD of the area with human activity,to confirm the reliability of air supply and exhaust methods of the HVAC system.The results show that using delaminated air-conditioning in a large space and forced exhaust air at the top have positive effects on thermal comfortableness of indoor environment.This paper provides guidance on the design of similar exhibition buildings.
