Problems solved by technology

In the prior art, the patent application number is 99116689 "lithium bromide absorption refrigeration device for automobiles", which provides the use of high-temperature engine coolant as a heat source, non-toxic water as a refrigerant, and lithium bromide aqueous solution as an absorbent to refrigerate Refrigeration device to replace the freon compression refrigerating machine used in automobile air conditioners that pollute the atmosphere. However, this solution requires a cooling water system, and the cooling water system of the automobile engine itself must also exist to ensure the cooling of the engine. Due to the The space is very limited, so the structure of this scheme is very complex
Therefore, this waste heat utilization scheme for automobile engines is not feasible

Description

technical field [0001] The invention relates to an absorption refrigeration device utilizing waste heat of an internal combustion engine, in particular to a dual-generator type waste heat absorption refrigeration device, which belongs to the technical field of air conditioning, refrigeration and heating. Background technique [0002] The practical efficiency of the internal combustion engine is generally about 35% to 40%, and the energy accounting for more than 1 / 2 of the fuel calorific value is taken away by the engine circulating cooling water and exhaust gas. Among them, the heat taken away by the cooling water accounts for 25% of the fuel calorific value. About 35%, how to recover and utilize this part of waste heat to serve people's lives, thereby improving the utilization rate of internal combustion engine fuel, is the subject that countries all over the world are currently studying. In the prior art, the patent application number is 99116689 "lithium bromide absorptio...
