Abstract

The invention discloses a cold and heat combined collection and storage device and method based on advanced sky radiation. The device is mainly composed of a heat storage unit, a solar collector and aradiation refrigeration and cold storage integrated unit, wherein the surface of the radiant refrigeration and cold storage integrated unit is coated with a layer of metamaterial, which has high emissivity in the 8-13[mu]m band and high reflectivity to full-spectrum sunlight. The device not only uses the high emissivity of metamaterials for refrigeration, but also collects sunlight reflected by the metamaterials for heating, which can achieve refrigeration and heating at the same time during the day. The designed radiation refrigeration and cold storage integrated unit directly stores the cold energy generated by the radiation effect in the phase change material without an intermediate heat exchange fluid, which improves energy conversion and storage efficiency, has a compact structure and can control the surface temperature of the metamaterial. Cold and heat cycle pipelines are reasonably designed, combined with cold storage and heat storage technology, to effectively overcome the instability of solar energy and realize stable cold and heat combined supply on the user side.

Description

technical field [0001] The invention relates to a combined cold and heat collection and storage device based on advanced sky radiation, and designs an efficient cold and heat energy acquisition, storage and joint supply method, which is especially suitable for places with abundant solar energy and combined cooling and heating, and belongs to radiation Refrigeration, solar harvesting and energy storage. Background technique [0002] Radiant cooling is a passive cooling method. The Earth's surface environment is transparent to electromagnetic waves with a wavelength of 8-13 μm, and this band is just the band of peak thermal radiation of objects at typical ambient temperatures. Therefore, due to the temperature difference between the object and the outer space (which can be regarded as an infinite space with absolute zero), it releases radiant heat, and most of the radiant heat can pass through the earth's surface to reach the outer space, thereby realizing the cooling of the ...
