北京大兴国际机场航站楼过渡季新风系统运行策略调适与优化
Operation strategy commissioning and optimization of outdoor air systems in Beijing Daxing International Airport terminal during transition season
摘要：
北京大兴国际机场航站楼核心区内区新风系统设计采用新风机组+全空气处理机组组合的方式进行新风供应。经实测发现，过渡季时室内新风量严重不足，室内效果无法达到设计预期。针对这一问题对机组运行方式展开调适优化并进行分组实测，验证不同运行模式下的室内CO2浓度，分析结果表明，过渡季新风系统新风量不足是其设计策略导致的。同时根据分析结果对过渡季新风系统运行策略进行修正，并得到了不同区域变频新风机组（OAU）和空调机组（AHU）运行频率的搭配。在该运行模式下，过渡季新风系统既可以满足室内需求，又兼顾节能效果，为后续北京大兴国际机场过渡季OAU-AHU新风系统的实际运行提供了运行依据。
Abstract：
The design of outdoor air system in the core area of Beijing Daxing International Airport terminal adopts the combination of outdoor air unit and all air handling unit for outdoor air supply. After actual measurement, it is found that the outdoor air rate is severely insufficient during the transition season, and the indoor effect could not meet the design expectations. To address this issue, commissioning and optimization are made to the operating mode of the unit, and group measurements are conducted to verify the indoor CO2 concentration under different operating modes. The analysis results show that the insufficient outdoor air rate of the outdoor air system during the transition season is caused by the design strategy. Based on the analysis results, the operating strategy of the outdoor air system during the transition season is revised, and the operating frequency of OAU and AHU in different regions is matched. Under this operating mode, the transition season outdoor air system can meet indoor needs while also considering energy saving effects. This provides an operational basis for the subsequent actual operation of the OAU-AHU outdoor air system in Beijing Daxing International Airport during the transition season.
