Problems solved by technology

However, there is a large difference in performance index between the traditional double-effect first-type absorption heat pump and the three-effect first-type absorption heat pump, and the same is true between single-effect and double-effect
In addition, when the temperature that needs to raise the waste heat is between the maximum heating temperature of the single-effect / double-effect / three-effect unit, or the temperature of the driving heat source during cooling is between the minimum driving heat source required by the single-effect / double-effect / three-effect unit Between temperatures, traditional double-effect and triple-effect units cannot allow us to make the best use of heat

Description

Technical field: [0001] The invention belongs to the technical field of low-temperature waste heat utilization heat pump / refrigeration. Background technique: [0002] In order to further improve the utilization rate of heat energy, people have proposed single-stage double-effect and single-stage three-effect first-class absorption refrigerator / heat pump units, among which the double-effect first-class absorption heat pump is a common heating / refrigeration field. unit. However, there is a large difference in performance index between the traditional double-effect first-type absorption heat pump and the three-effect first-type absorption heat pump, and the same is true between single-effect and double-effect. In addition, when the temperature that needs to raise the waste heat is between the maximum heating temperature of the single-effect / double-effect / three-effect unit, or the temperature of the driving heat source during cooling is between the minimum driving heat source r...
