| description | The utility model belongs to the technical field of tunnel freezing damage prevention and control, and discloses a cold region tunnel portal energy storage adjusting type double-outlet air curtain cold insulation anti-freezing device which comprises an air curtain cold insulation unit, a phase change energy storage unit and a temperature control unit. And the air outlet comprises double outlets which respectively point to the outside of the tunnel and the inside of the tunnel. When the monitored temperature value is higher than or equal to the phase change temperature of the phase change material, an energy storage working mode is started, nozzles pointing to the interior of the tunnel are opened, and the phase change material absorbs heat and stores energy; and when the monitored temperature value is lower than the phase change temperature of the phase change material, the cold insulation working mode is started, the nozzles pointing to the outside of the tunnel are opened, and an air curtain for blocking ex |
