Problems solved by technology

At this time, if the solution generation process is completed by a single-effect process, the temperature difference is not fully utilized, and the performance index of the cycle is not ideal; if the solution generation process is completed by a classic double-effect process, it is required to have a gap between the driving heat medium and the heated medium. Sufficient temperature difference, which requires a new circulation process to compensate

Description

Technical field: [0001] The invention belongs to the technical field of low-temperature waste heat utilization and heat pump / refrigeration. Background technique: [0002] The first type of absorption heat pump uses the temperature difference between the driving heat medium and the heated medium as the driving force. When the driving temperature difference is large, a double-effect or multi-effect process should be used to fully utilize the driving heat; any heat transfer link The waste of temperature difference will reduce the utilization rate of heat energy. Only by making full use of the temperature difference can a reasonable thermodynamic perfection be guaranteed. [0003] When the temperature range of the heated medium is wide, especially when the driving heat medium is used to provide sensible heat, the temperature difference between the high-temperature exothermic part and the low-temperature exothermic part of the driving heat medium and the heated medium is differen...
