Solar absorption, absorption cascade refrigeration and heating system

Abstract

The present invention proposes a solar energy adsorption and absorption cascaded refrigeration and heating system. During the day, the system uses photothermal and photocooling solar energy conversion devices to collect solar heat to provide heat for the generator, and at the same time desorb the adsorbate and adsorbent in the device. At night, the adsorbent in the device absorbs the adsorbate, and the heat of adsorption generated during the adsorption process can provide heat for the nighttime operation of the generator, and at the same time, the cooling capacity generated during the evaporation of the adsorbate liquid can cool the condenser and absorber . Photothermal and photocooled solar energy conversion devices include housings, closed chambers, concentrators, inner pipes, adsorbents, liquid collection chambers, walls and other components. The wall and the condenser form a closed liquid collection chamber, the inner pipe passes through the center of the liquid collection chamber, and a closed chamber is formed between the wall and the shell, and the closed chamber communicates with the outside through a pipe, and the inner pipe An adsorbent is immobilized on the outer surface. The device realizes the two-stage utilization of solar cooling and heating, realizes the nighttime operation of the absorption refrigeration system without auxiliary heat source mode, and improves the utilization rate of solar energy.

Description

technical field [0001] The invention relates to the field of solar refrigeration and heating, and more specifically relates to a solar energy absorption and absorption cascade refrigeration and heating system. Background technique [0002] There are two main forms of solar refrigeration systems: absorption refrigeration and adsorption refrigeration. Due to the lack of solar heat at night in the absorption refrigeration system, auxiliary heat source heating is often required, which reduces the efficiency of the refrigeration system. In the adsorption refrigeration system, due to the limitation of its principle, it is often not possible to continuously circulate refrigeration, and it can only provide cooling capacity at night, which limits its application. In order to solve this problem, the present invention combines absorption refrigeration and adsorption refrigeration, and proposes a solar energy adsorption, absorption cascade refrigeration and heating system, the core com...
