Beijing Daxing International Airport is surveyed.And during most periods of the transitional season,the AHUs can operate in the fresh air mode,indicating the potential for utilizing natural ventilation instead of mechanical ventilation.Combined with the climate conditions in Beijing,the available hours of natural ventilation in the transition season are summarized as 1383 hours.The protective curtain wall at the bottom of the covered walkway on the second floor of the airport is equipped with electric ventilation windows,while the top of the fourth floor is equipped with aerodynamic skylights.The natural ventilation effects of the covered walkway at Beijing Daxing International Airport during the day and night under two operating conditions were calculated using CFD software during the transitional season.Under the prevailing winds of transitional season,the external pressure difference of the walkway facing the weak winds exceeds 1Pa,which meets the requirements of natural ventilation.Based on indoor airflow calculations,this study proposes natural ventilation control strategies for the terminal building at Beijing Daxing International Airport and calculates the corresponding energy-saving potential.
