The invention provides a double absorption-double generation system and multi-terminal heat supply third kind absorption heat pumps, which belong to the technical field of heat pumps. In the system, a second absorber is communicated with an absorption-generator by a first solution heat exchanger; the absorption-generator is communicated with a generator by a second solution pump and a second solution heat exchanger; the generator is communicated with a first absorber by the second solution heat exchanger; the first absorber is communicated with a vapor separation chamber by a solution throttle valve and the absorption-generator; the vapor separation chamber is communicated with the second absorber by a first solution pump and the first solution heat exchanger; the generator is also provided with a refrigerant vapor channel and a driving thermal medium pipeline for communicating with the outside respectively; the first absorber is also provided with the refrigerant vapor channel and a heated thermal medium pipeline for communication with the outside respectively; a refrigerant liquid pipeline is arranged outside and is communicated with the first absorber; the first absorber is also provided with the refrigerant vapor channel for communicating with the second absorber; the absorption-generator is also provided with the refrigerant vapor channel for communicating with the outside; the vapor separation chamber is provided with the refrigerant channel for communicating with the outside; and the second absorber is also provided with the heated medium pipeline for communicating with the outside, thus the double absorption-double generation system is formed; and a series of multi-terminal heat supply third kind absorption heat pumps are formed by arranging other parts on the double absorption-double generation system.
Description
Technical field: [0001] The invention belongs to the technical field of heat pumps. Background technique: [0002] According to the principle of thermodynamics, for the waste heat of a certain temperature, the higher the temperature is, the lower the performance index of the heat pump unit will be; as the heating temperature gradually increases, the performance index of the heat pump unit will gradually decrease. There should be continuous correspondence and changes between them. However, for the third type of absorption heat pumps with different efficiency numbers and different stages, their working parameters are not continuously changed, and their performance indices are not coherent but have great differences, and the working parameters and performance indices cannot be continuously corresponded. [0003] From the perspective of improving the heating temperature of the third type of absorption heat pump, in order to realize the continuity of the thermodynamic parameters...
