Problems solved by technology

[0005] Searching the existing patents and literature, Li Tingxian et al. proposed a three-effect adsorption refrigeration system, which contains three kinds of solid adsorbents. By using two adsorption heat recovery processes to combine three sets of single-effect adsorption refrigeration systems, the system is realized in a single Under the condition of high-temperature heat input, the low-temperature cooling capacity is output three times; however, there are still few reports on the effective recovery of adsorption heat, so the multiple recovery of adsorption heat in a system will greatly limit the performance of the system; in addition, Li Tingxian et al. Does not consider the operation process of the three-effect adsorption refrigeration system when the temperature of the heat source changes
