Professional custom-made high-efficiency and low-noise units resolve pipeline conflicts in irregular spaces, achieving precise temperature control and energy conservation with noise reduction in large spaces.
The total floor area is 683,300 m², equivalent to about 95 standard football pitches, making it one of the largest single-terminal buildings in the world. It integrates high-speed rail, intercity rail, and metro underground to achieve "air-rail intermodal transport." Connected to the existing Terminals 1 and 2, the annual passenger throughput capacity can reach 120 million.
The "flower crown" shape of T3 consists of eight curved "petals," creating irregular and variable internal spaces. HVAC ducts and pipes must run through limited ceiling mezzanines. The project team relies on a full-discipline 3D BIM model for millimeter-level detailed design, enabling "visualized positioning" of fans, air ducts, and MEP services in advance. This avoids conflicts with structural beams and fire protection pipes, ensuring that the clear height of passenger corridors is 10–15 cm higher than design standards.
In the baggage sorting area, which has a clear height of 13.5 m, four levels of equipment rails, over 2,500 suspension rods, and dense MEP services intertwine, resembling "giant snakes threading through bamboo skewers." Fan installation must avoid steel platform hangers and baggage system rails. The project adopts collaborative installation technology, overlaying the HVAC model with the baggage system and steel structure models. Through 3D simulation, crossing points are predicted in advance, achieving "zero-collision" construction.
As the "Flower Crown of Guangzhou," T3 emphasizes ecology and passenger experience, setting higher standards for temperature and humidity control, indoor air quality, and noise levels of the air conditioning system. The fan selection adopts high-efficiency, low-noise axial fans with intelligent VFD control, combined with indoor CO₂ sensors to dynamically adjust airflow. This ensures fresh air in the hall while reducing energy consumption and operational noise, aligning with green building concepts.
South China is characterized by high temperature and high humidity, making underground equipment rooms prone to condensation. The project selects fans with IP55 or higher protection rating, with moisture-proof and anti-corrosion treatment for motors and impellers. Sealed equipment rooms and drainage systems are also provided to ensure long-term stable operation.
