Airport

Core requirements

Ultra-large spaces feature uniform ventilation, ample fresh air in high-traffic areas, moisture and odor resistance in baggage sorting zones, and energy-efficient operation.

 

Dedicated technical adaptation

• Layered and zoned ventilation in the terminal building The terminal building is divided into distinct zones—including departure halls, arrival halls, waiting areas, and commercial zones—using a “ceiling-supply air + side-return air” ventilation system. Paired with large-diameter variable-frequency fans, this system automatically adjusts airflow rates according to the pedestrian density in each zone. In the waiting area, CO₂ concentration is maintained at or below 900 ppm, effectively preventing localized stuffiness and overheating.

• Moisture-proof and odor-removing for baggage sorting areas Configure a dehumidifying ventilation system that monitors humidity in real time. When the humidity exceeds 70%, the dehumidification function will automatically activate to prevent luggage from becoming damp and moldy. Meanwhile, to address potential odors in the sorting area, the fresh-air system is equipped with an activated carbon filtration module to enhance air freshness.

• Energy-saving optimized design Leveraging the tall architectural features of the airport building, a “heat recovery + natural ventilation assistance” approach is adopted. In winter, waste heat from exhaust air is recovered to preheat fresh air; in summer, roof-mounted exhaust vents assist natural ventilation. This reduces the combined energy consumption of the air-conditioning and ventilation systems, achieving an overall energy-saving rate of over 35%.
