The absorption refrigerator includes ammonia absorption refrigerator and lithium bromide absorption refrigerator, which uses binary solution of lithium bromide-water as working medium to complete the refrigerating circulation. Wherein, water is a refrigerant, lithium bromide is an absorbent, and the concrete process comprises two parts: in the first part, the lithium bromide water solution is heated and boiled in the generator by the heat source, and the generated refrigerant vapor is condensed into refrigerant water in the condenser.
