HSUEHSHAN TUNNEL VENTILATION SYSTEM- INTRODUCTION -The ventilation system of the Hsuehshan Tunnel is a longitudina
l 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.

1. Longitudinal Ventilation System Without Air Interchange Station Maximum Fan Capacity: 100%+47%=147%
2. Longitudinal Ventilation System with Air Interchange Station Maximum Fan Capacity:100%+24%=124%(The peak traffic in each tube would not happen simultaneously)

1. Longitudinal Ventilation System without Air Interchange Station
North bound Tube : 5 Ventilation Shafts
South bound Tube : 2 Ventilation Shafts
2. Longitudinal Ventilation System with Air Interchange Station
Northbound Tube : 3 Ventilation Shafts
Southbound Tube : 3 Ventilation Shafts
BENEFITBENEFIT : To Reduce Quantity of Ventilation Shafts
