Abstract

Vehicles and methods for cooling a cabin using a cold roof of the vehicle are provided. The vehicle includes a roof, a cabin, and an insulation layer disposed between the roof and the cabin. The vehicle also includes a passage that fluidly couples the roof with the cabin. The passage is switchable between an open mode and a closed mode. The passage is switched between the open mode and the closed mode depending on a relationship between a roof temperature, a cabin temperature, and/or a threshold temperature. The passage may be formed through the insulation layer or extend outside of the insulation layer fluidly coupling the roof with the cabin.
