SOLAR ENERGY UTILIZATION AND RADIATIVE COOLING COMPOSITE SYSTEM

摘要

Provided are a solar energy utilization and radiative cooling composite system, comprising a radiative cooling system and a solar energy conversion and utilization system; the radiative cooling system comprises a radiative cooling apparatus and a radiative-cold energy collection and utilization system; the solar energy conversion and utilization system comprises a solar energy conversion apparatus and an energy utilization system; the solar energy conversion apparatus is located on the two sides of the radiative cooling apparatus; the two constitute a composite structure energy conversion apparatus; the radiative cooling apparatus converts heat energy into electromagnetic waves, radiating electromagnetic waves into space to achieve cooling, and simultaneously reflecting the solar energy irradiated on the surface to the solar energy conversion apparatus; the solar energy conversion apparatus receives direct sunlight, sunlight reflected by the radiative cooling apparatus, and radiated electromagnetic waves from the body of the radiative cooling apparatus, and converts same into electricity, thermal energy, or cold, thus achieving the overlapping utilization of solar energy and radiative cooling in the same area. The invention greatly improves the energy utilization rate and energy density per unit area.
