Abstract
The present invention discloses a ventilation system for tunnel engineering. The ventilation system is for use in a tunnel having at least one first shaft and at least one second shaft. The ventilation system includes a heat collecting device, a cooling device, and at least one piping system. The piping system is connected to the heat collecting device and the cooling device. A portion of the piping system coils inside the first and second shafts. Increasing the temperature in the first shaft and/or decreasing the temperature in the second shaft introduces ambient air into the tunnel via the first and second shafts by natural convection, thereby decreasing and maintaining the temperature in the tunnel and renewing air therein. The ventilation system advantageously features low power consumption and low manufacturing costs and is fit for use in long-distance tunnel engineering that requires multi-point installation of the ventilation system.
