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. AXIAL FLOW FAN

– Air Exchange Stations

Supply Air Fans: 12 sets (4 sets per each station)

Exhaust Air Fans : 12 sets (4 sets per each station)

– Air Interchange Stations

Air Interchange Fans : 12 sets (4 sets per each station)

2. JET FAN

112 sets (56 sets per each 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)

Ventilation Flow

Peak Traffic in North bound

Peak Traffic in South bound

North bound Tube (Uphill) 100% 62%

South bound Tube (Downhill) 24% 47%



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
