PCA Airport Ground Air Conditioning Hose | Adapted to Aircraft Air Conditioning / Boarding Bridge Cooling Systems

1. Excellent durability  

   - Extreme environmental adaptation: Multi-layer composite material, resistant to temperature difference from -30°C to +80°C, UV, oil and chemical corrosion resistance, prolonging service life.  

   - Resistant to pressure and abrasion: Unique corrugated structure design avoids bending and collapsing, and maintains smooth airflow even when frequently dragged or mechanically crushed.  

2. Efficient energy transmission  

   - Ultra-low heat loss: The high-density heat insulation layer effectively reduces energy loss during cold/hot air transfer, improves the energy efficiency ratio of the air conditioning system, and shortens the time for temperature adjustment in the airplane cabin.  

   - High-flow design: Optimized inner diameter size and hydrodynamic structure ensure high air volume delivery to meet the rapid cooling/heating needs of wide-body airliners (e.g. A380, B787).  

3. Convenient and safe operation 

   - Lightweight + flexible expansion and contraction: weight 40% less than traditional metal hose, support for single person fast docking; expansion ratio of 3:1, adaptable to different models of the interface position, reduce the physical consumption of ground staff.  

4. Green and Economical  

   - Reduce APU dependence: By replacing the aircraft auxiliary power unit (APU) with a stable energy supply, fuel consumption can be reduced by 50-80 kg on a single flight, reducing CO₂ emissions and noise pollution.  

   - Low maintenance cost: modularized interface design, local damage can be quickly replaced parts, reducing the full life cycle maintenance costs.  

The PCA Airport Ground Air Conditioning Hose is a specialized piece of equipment designed to provide air conditioning for aircraft during ground stops. Its core function is to deliver cooled or heated clean air to the cabin by connecting the airport ground air conditioning system (PCA, Pre-Conditioned Air) to the aircraft, thus reducing the energy consumption of the aircraft relying on its own auxiliary power unit (APU). The following are its typical application scenarios:

1. Environmental control during aircraft parking

- Boarding gate/porch area:  

  When the aircraft is parked at the gate, the air conditioning hoses connect the ground PCA system with the aircraft air intake to provide fresh air at the right temperature to the cabin, ensuring the comfort of passengers and crew during boarding, deboarding and cleaning and maintenance.

- Extreme Climate Environments:  

  Quickly regulates the cabin temperature under high temperature (e.g. Middle East, tropical areas) or severe cold (e.g. Northern Europe, high altitude airports) conditions to avoid fuel consumption and emissions caused by overuse of the APU.

2. Aircraft repair and maintenance scenarios

- Hangar or tarmac maintenance:  

  Maintain the temperature and humidity of the cabin and electronic equipment compartments through the ground air conditioning hoses when the aircraft is parked for a long time for maintenance to prevent the equipment from being damaged or condensation due to high/low temperatures.

- Energy Saving and Environmental Needs:  

  Relying on ground air conditioning systems to reduce noise pollution and carbon emissions after shutting down the aircraft's APU, in compliance with international airport environmental standards (e.g. ACI/ICAO requirements).

3. Low-cost airports or temporary take-off and landing scenarios

-Distant airplane position without corridor bridge:  

  When the aircraft is parked in the remote aircraft position, the mobile PCA unit with hose is quickly deployed to replace the APU to supply air to the cabin, reducing the operation cost.

- Emergency Protection:  

  In case of APU failure or power supply interruption, ground air-conditioning hoses can be used as a backup solution to ensure normal flight dispatch.

4. Cargo aircraft and special aircraft type adaptation

- Cargo aircraft temperature control:  

  Provide a stable temperature-controlled environment for cargo planes transporting temperature-sensitive cargo (e.g., medicine, fresh food) to avoid cargo damage.

- Wide-body and narrow-body aircraft compatibility:  

  The hose design adapts to the interfaces of different models (e.g. Boeing and Airbus series) to ensure versatility and fast switching.
