Description

technical field

[0001] The invention relates to the technical field of refrigeration, in particular to a membrane distillation heat recovery absorption refrigeration device. Background technique

[0002] The rapid development of absorption refrigeration technology is inseparable from the current research on energy and environmental protection issues. The existing research hotspots have two directions. The first is the absorption refrigeration technology driven by low-grade heat sources (such as solar energy or waste heat). This kind of technology is to make some improvements to the process on the basis of the two-stage absorption cycle to improve the refrigeration efficiency of the system; the second is the high-efficiency absorption refrigeration technology, which mainly studies the multi-effect absorption refrigeration cycle, researches injection, adsorption, pressurization Research on the absorption compound refrigeration cycle, the working medium of the absorption refrig...
