Design of Intelligent Power Supply System for Expressway Tunnel

Review of Passive Strategies for Ventilation and Air-Conditioning Energy Saving in Underground Metro Stations

“…The piston effect generated by train driving not only bring in the outside fresh air and save the mechanical ventilation energy, but also provide free heating opportunities. Besides, some reports [31,32] proposed to use piston wind to support advertising lighting in stations, as the velocity of airflow can reach 6-8 m/s in tunnel.…”

The research for designing the LED tunnel light for highway tunnels

“…Because tunnels are often located in remote areas, the construction of power supply cables is generally characterized by long distances, high investment, and high construction costs. Wang et al [ 14 ] proposed an environmentally friendly and energy-saving lighting system. Using the piston wind generated by the car in the tunnel as the power combined with solar energy and physical lighting can solve the high construction cost problem of the highway tunnel section.…”
