Solar energy refrigerator

Abstract

The invention discloses a solar energy refrigerator. The solar energy refrigerator comprises a photo-thermal refrigerating system; the photo-thermal refrigerating system comprises a solar thermal collector which is used for converting solar energy into heat energy, a heat accumulator which is used for receiving and accumulating heat energy produced by the solar thermal collector, an adsorption bed in which refrigerating fluid is accommodated and which is used for adsorbing and desorbing the refrigerating fluid, a high-temperature heat pipe device which is used for transferring heat energy which is accumulated by the heat accumulator to the adsorption bed to ensure that the adsorption bed can desorb the refrigerating fluid, a low temperature heat pipe device which is used for dispersing heat in the adsorption bed into environment to ensure that the adsorption bed can adsorb the refrigerating fluid, and a refrigeration unit which is used for refrigerating by using the refrigerating fluid which is desorbed in the adsorption bed. The adsorption bed is heated and cooled by using the heat pipe devices, so that the heat transfer efficiency is high and the control of the heating and cooling processes is realized; and due to the adoption of the heat accumulation device, the adsorption bed can be heated by using accumulated heat when the sunshine is not sufficient. The low-temperature heat pipe device can accelerate the process of refrigeration cycle.

Description

technical field [0001] The invention relates to a solar refrigerator, in particular to a refrigerator capable of realizing heating analysis and cooling adsorption process control based on solar photothermal, belonging to the field of photothermal refrigeration. Background technique [0002] Solar energy is the most widely used clean renewable energy. Solar refrigeration technology has good seasonal matching, that is, the solar radiation is strong in summer, and the corresponding cooling demand is also large, while the solar radiation is relatively weak in winter, and the cooling demand is also small at this time. Based on this, solar refrigeration technology has received more and more attention and research. [0003] With the development of the global economy and the continuous improvement of people's quality of life, saving energy and protecting the environment have generally become common concerns of people. Solar thermal refrigerators use solar energy, a non-polluting, c...
