[0003] The absorption refrigeration device involves many links, including the heat absorption process, the condensation heat release process, the heat absorption evaporation process, the heat release absorption process and the sensible heat recovery process, that is, a total of 5 heat transfer processes and two mass transfer processes. The process and system are more complicated, and the efficiency is not high; while the high-pressure steam of the jet refrigeration device passes through the ejector, there is a large irreversible loss due to the mixing process and the high-speed flow process, and the efficiency is very low.
