Description

technical field [0001] The invention relates to a refrigeration device, in particular to a compressed air energy storage refrigeration device. Background technique [0002] Among the existing refrigeration devices, the traditional closed Freon vapor compression refrigeration system is the most perfect and the most widely used. However, this kind of refrigeration device consumes a lot of energy, and is generally used in the peak period of electricity consumption when electricity consumption is relatively concentrated, which easily causes the problem of power shortage for a period of time, and intensifies the contradiction between peak and valley power supply. On the one hand, with the continuous improvement of people's living standards, refrigeration devices such as household air conditioners and refrigerators have begun to enter thousands of households. On the other hand, the continuous development of industry and other industries has also raised more and more demands on the...
