摘　　要：市级会议中心承担着全年各类大型的会议,会议中心的空调方案既影响能耗也影响着室内环境,并影响与会人员的热舒适和开会的效果。本文介绍了无锡某会议中心项目暖通工程的特点分析,提出了侧送风+地面辐射方案,其中采用地面辐射系统末端设计,夏季有效降低人员辐射温度,送风空气诱导至人员所处区域;侧送风更贴合地面,新鲜空气送至人员呼吸区;同时冬季显著提高热舒适性,提高室内高大空间送风的均匀性。结合无锡的气候特点提出了重视渗透风管理的防结露措施。并对黑白大理石用作墙面材料的差异进行了对比,发现选用黑色大理石有利于系统风量的降低。本研究为会议中心高大空间的空调系统设计提供了一定的借鉴。The municipal conference center undertakes all kinds of large-scale meetings throughout the year.The air conditioning scheme of the conference center affects not only the energy consumption,but also the indoor environment,as well as the thermal comfort of the participants and the effect of the meeting.This paper introduces the characteristics of HVAC engineering of a conference center project in Wuxi,and puts forward the scheme of side air supply+ground radiation,in which the end design of ground radiation system is adopted to effectively reduce the personnel radiation temperature in summer and induce the air supply to the area where the personnel are located.The side air supply is closer to the ground,and the fresh air is sent to the personnel breathing area.At the same time,the thermal comfort is significantly improved in winter,and the uniformity of air supply in large indoor spaces is improved.Combined with the characteristics of Wuxi climate,this paper puts forward the anti-condensation measures through infiltration wind management.By comparing the differences between black and white marble used as wall materials,it is found that the selection of black marble is conducive to the reduction of system air volume.This study provides a certain reference for the large space air conditioning system design of in the conference center.
