Analysis of ventilation and air conditioning coordinated operation energy-saving system in boarding bridges

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.
