15 TPT-WG29, Chinese Taipei 29 th APEC Transportation Working Group Meeting, Chinese Taipei, 9-13 July 2007 HSUEHSHAN TUNNEL VENTILATION SYSTEM - INTRODUCTION - The ventilation system of the Hsuehshan Tunnel is a longitudinal ventilation system. The system contains three air exchange stations and three air interchange stations. At each air exchange stations the polluted air in each tube is exchanged for fresh air using separate fresh and exhaust air shafts. At each air interchange station the air in one tube is diverted into the other tube. This interchange of air between the two tubes permits the heavily polluted air in one tube is replaced with lightly polluted air from the other tube while the lightly polluted air in one tube is replaced with heavily polluted air from the other tube.
