摘　　要：针对办公楼集中设置的会议室区,阐述空调系统的节能设计与控制方式。根据功能区合理划分水环路并进行冷热量计量减少能源浪费。风机盘管分环路设置能量阀,新风机组设置能量阀,避免水系统大流量小温差运行。新风系统设置空气-空气能量回收装置,过渡季关闭空气-空气能量回收装置,全新风运行。冬季通过合理设计实现新风供冷。新风机组根据最大人员需求量选型,变风量运行。设置二氧化碳浓度监测装置、手动自动控制阀门实现新风按需供给。采用CFD模拟,使气流组织更加合理,空调效果更优。The energy saving design and control method of air conditioning system are expounded for the meeting room area centrally set in office building.Divide the water loop reasonably according to the functional area and carry out the cooling and heat metering to reduce the energy waste;The fan coil sub-loop is equipped with energy valve,and the fresh air unit is equipped with energy valve to avoid the operation of the water system with large flow and small temperature difference.Air-air energy recovery device is installed in the fresh air system,and the air-air energy recovery device is closed in the transition season,and the whole fresh air operation is carried out.In winter,the fresh air cooling is realized through reasonable design.The fresh air unit is selected according to the maximum personnel demand and runs with variable air volume.Set carbon dioxide concentration monitoring device,manual automatic control valve to achieve fresh air supply on demand;Using CFD simulation,the air distribution is more reasonable,the air conditioning effect is better.
