摘　　要：天棚辐射+新风系统是办公建筑中常用的一种温湿度独立系统。对地处北京地区的采用了天棚辐射+新风的办公建筑中某一大开间区域的夏季设计工况进行CFD建模,模拟天棚、新风系统承担不同冷负荷比例时室内工作区域的温湿度场、舒适度等情况。模拟结果显示,在该大开间的设计工况下,并不是辐射系统承担的比例越大越好,而是当辐射系统承担冷负荷比例为50%时,系统的供冷效果最好。此结论仅为模拟结果,实际情况还有待验证。In office building,ceiling radiant and new-air system is always applied as a sort of independent control system for temperature and humidity. By modeling the open office using ceiling radiant and new-air system in Beijing,this paper provides some simulation results of indoor working area ＇s temperature-humidity fields and PMV fields,which show that in the design condition,the best cooling effort can be attained not when the radiant system＇s load is biggest,but when the radiant system＇s load percentage is 50%. This result is only attained by simulating,and should be tested in reality.
