| titleOfInvention | Tunnel aeration cooling system based on phase change cold storage |
| abstract | The invention provides a tunnel ventilation cooling system based on phase change cold accumulation, which comprises a cold accumulation section and a ventilation cooling section, wherein the cold accumulation section is a closed circulating system consisting of a tunnel geothermal energy heat exchanger, a water pump, a water distribution pipe, a water collection pipe and a phase change cold accumulation plate in a cold accumulation chamber; the phase change cold accumulation plate completes cold accumulation in the cold accumulation chamber firstly, and transports a ventilation cooling section close to a tunnel construction surface along a tunnel, the section comprises a heat insulation layer, a movable shielding door, a ventilation pipe, a cooling pipeline and a water pump, the heat insulation layer and the movable shielding door form a closed heat insulation space behind a tunnel excavation face, and the air in the ventilation pipe is cooled by the phase change cold accumulation plate to cool the closed heat insulation space. Compared with the existing artificial ice making and cooling mode, the invention has the remarkable improvements of convenient construction, high energy efficiency, reproducibility, low operation cost and the like. |
