Description

technical field [0001] The present invention relates to an adsorption refrigeration cycle, in particular to a two-stage retro-mass adsorption refrigeration cycle system and method. Background technique [0002] In the field of refrigeration and air conditioning, conventional vapor compression refrigeration uses refrigerants that may cause ozone layer depletion and greenhouse effects as working fluids, and consumes a large amount of electric energy. Therefore, its development also faces two major problems in energy and the environment. Adsorption refrigeration driven by low-grade heat energy and using natural working fluid can effectively reduce power consumption and achieve good environmental protection effects. It is an effective supplementary solution to current refrigeration technology. [0003] After years of development, adsorption refrigeration has developed from the initial intermittent cycle to continuous cycle, heat recovery cycle, mass recovery cycle, and heat reco...

AI Technical Summary

Problems solved by technology

However, compared with the heat-driven absorption refrigeration system, the existing adsorption refrigeration system has the disadvantage of low efficiency.

Improving the efficiency of the adsorption refrigeration system can be achieved by further increasing the cycle adsorption capacity. However, the existing mass recovery cycle has only one mass recovery cycle, resulting in a very limited increase in the cycle adsorption capacity.
