Radiant refrigeration roof

Abstract

The invention discloses a radiant refrigeration roof. The radiant refrigeration roof comprises a solar cell panel, a water-cooling layer, a thermoelectric module layer and a radiation plate which aresequentially arranged from outside to inside. The solar cell panel is electrically connected with the thermoelectric module layer to provide direct-current electricity for the thermoelectric module layer, a plurality of N-shaped semiconductors and a plurality of P-shaped semiconductors are arranged in the thermoelectric module layer, the thermoelectric high-temperature end of the thermoelectric module layer and the water-cooling layer are arranged in an attached mode to provide heat for the water-cooling layer, the thermoelectric low-temperature end of the thermoelectric module layer and the radiation plate are arranged in an attached mode to provide the cooling capacity for the radiation plate so as to conduct radiation on the indoor space, a water-cooling channel and a cooling water inlet communicating with the water-cooling channel are formed in the water-cooling layer. According to the radiant refrigeration roof provided by the invention, the problem that the hot-end efficiency ofa photoelectric electricity generation module and a thermoelectric module becomes low along with the time is solved, and meanwhile, generated overheating heat is effectively utilized to provide hot water for a user.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a radiation cooling roof. Background technique [0002] Thermoelectric materials are functional materials that can convert thermal energy and electrical energy. Based on the Seebeck effect and Peltier effect of semiconductor materials, they can use temperature differences to generate electricity, and can also use electrical energy for cooling and heating. At present, semiconductor temperature difference power generation technology has been applied to coastal hanging lights, buoy lights, power supplies for border defense communications, power supplies for unmanned relay stations in oil pipelines, field portable power supplies, and power supplies for seabed exploration, spacecraft and various artificial satellites. [0003] Contrary to the principle of thermoelectric materials converting electrical energy, when direct current is given to thermoelectric materials, the...
