Analysis of ventilation and air conditioning coordinated operation energy-saving system in boarding bridges
摘要：
针对机场航站楼登机桥空调系统存在的全年运行能耗偏高问题,提出了与航班信息联动的通风与空调协同运行节能系统。利用CFD模拟与现场实测相结合的验证方法,分析了不同运行模式下的空气流动特性与热环境舒适性。结果表明,案例建筑登机桥空调系统运行时间缩短约30%～50%,单位面积年耗电量降低约50%～60%,增量投资回收期约6.3 a,对推动绿色机场建设具有参考价值。
Abstract：
A ventilation and air conditioning coordinated operation energy-saving system linked with flight information is proposed to address the problem of high annual energy consumption of the air conditioning system in airport terminal boarding bridges.Using a verification method that combines CFD (computational fluid dynamics) simulation with on-site measurement,the air flow characteristics and thermal environment comfort under different operation modes are analysed.The results show that the operating time of the air conditioning system in the boarding bridge of the case building is reduced by about 30%-50%,the annual electricity consumption per unit area is decreased by about 50%-60%,and the payback period for incremental investment is about 6.3 years,which has reference value for promoting the construction of green airports.
