The invention discloses an adsorption type solar energy light condensing automatic temperature regulation radiation system for a cold region, a roof and a wall, and relates to the technical field of solar energy. The system comprises condensers, first communication pipelines, adsorption devices, second communication pipelines, liquid storage devices and a heat-accumulating layer. The condensers are installed in an external environment, and the light ray output ends of the condensers are connected to one ends of the first communication pipelines. The other ends of the first communication pipelines are connected with the adsorption devices. The adsorption devices are located in the heat-accumulating layer in an embedded connection mode, and the adsorption devices comprise adsorbents. One ends of the second communication pipelines are connected to the adsorption devices, and the other ends of the second communication pipelines are connected to the liquid storage devices. The liquid storage devices are connected to the upper parts of the adsorption devices and are arranged close to the outside world for storing gaseous and liquid adsorbates. The liquid storage devices include water fenders, through holes are formed in the centers of the water fenders, and the water fenders are connected to the bottoms of the liquid storage devices and the through holes are aligned with end openingsof the other ends of the second communication pipelines. The heat-accumulating layer is connected to the indoor surface of the wall in a laying mode. The adsorption type solar energy light condensingautomatic temperature regulation radiation system for the cold region, the roof and the wall have the advantage of remarkable radiation temperature regulation effect.
