Abstract

The invention discloses an electricity-water cogeneration system of solar energy, comprising a silicon plate, wherein the back surface of the silicon plate is an evaporation cavity; working medium pairs of silica gels and water are arranged in the evaporation cavity; the evaporation cavity is connected with a condenser by a steam pipeline; the condenser comprises a coil pipe and a fin; the tail end of the coil pipe is provided with a water storage chamber; the upper and lower surfaces of the condenser are fixed with a condensing surface respectively so as to condense water in air at night; the condenser and the condensing surface are sealed and surrounded by two thermal storage shells which are made of thermal storage materials; and the outer surfaces of the thermal storage shells are covered by insulated materials. The electricity-water cogeneration system solves the problem of radiation of the silicon plate in the solar power generation process in deserts by using the phase change of the water, and realizes the electricity-water cogeneration by using refrigerating quantity of adsorbates for refrigeration to condense and collect the water in the deserts at night.

Description

technical field

[0001] The invention relates to a solar power-water cogeneration system, which belongs to the technical field of new energy. Background technique

[0002] Under the background of the increasingly serious energy situation and environmental pollution, solar energy, as a clean, stable and inexhaustible new energy source, has attracted more and more people's attention in its application and development.

[0003] The total amount of solar energy on the earth is very rich, but high-quality solar resources with high intensity and long sunshine hours are mainly concentrated in desert or desert areas. Moreover, solar power plants occupy a large area, so large-scale photovoltaic power plants are generally located in deserts or desert areas.

[0004] In the process of photovoltaic power generation, only about 17% of solar energy is converted into electrical energy, and the remaining energy is dissipated in the form of heat energy. If the heat cannot be effectively diss...
