PROBLEM TO BE SOLVED: To provide a tunnel ventilation facility/method of excellent energy efficiency that may be applied even to an extensive tunnel or a tunnel with a plurality of branches.SOLUTION: A tunnel ventilation facility/method includes a main ventilation channel 2, an auxiliary ventilation channel 6, relay equipment 3, main ventilation means 1, and auxiliary ventilation means 5. The relay equipment 3 has a buffer space into which air from the main ventilation channel 2 flows in, and the air in the buffer space flows out into the auxiliary ventilation channel 6. The tunnel ventilation facility/method further includes a pressure gauge 9 for measuring pressure in the buffer space, main control means for controlling a ventilation volume from the main ventilation means 1 on the basis of a measurement value of the pressure gauge 9, and auxiliary control means for controlling a ventilation volume from the auxiliary ventilation means 5.SELECTED DRAWING: Figure 1 |
