Detailed implementation method:

[0049] First, it should be noted that the structure and process are not repeated unless necessary; obvious processes are not described. The invention will now be described in detail with reference to the accompanying drawings and examples.

[0050] Figure 1 The first type of heat-driven jet-absorption heat pump shown is implemented as follows:

[0051] (1) Structurally, it mainly consists of an absorber, a solution pump, a solution heat exchanger, a generator, an ejector, a condenser, a booster pump, a steam generator, a throttling valve, and an evaporator; the absorber 1 has a dilute solution pipeline connected to the generator 4 via the solution pump 2 and the solution heat exchanger 3; the generator 4 also has a concentrated solution pipeline connected to the absorber 1 via the solution heat exchanger 3; the generator 4 also has a refrigerant vapor channel connected to the low-pressure steam inlet of the ejector 5; the ejector 5 also has a medium-pressure refrigerant vapor channel connected to the condenser 6; the condenser 6... Furthermore, the refrigerant liquid pipeline is connected to the steam generator 8 via the booster pump 7. The steam generator 8 also has a high-pressure refrigerant steam channel connected to the high-pressure steam inlet of the ejector 5. The condenser 6 also has a refrigerant liquid pipeline connected to the evaporator 10 via the throttle valve 9. The evaporator 10 also has a refrigerant steam channel connected to the absorber 1. The steam generator 8 and the generator 4 also have high-temperature heat medium channels connected to the outside. The absorber 1 and the condenser 6 also have heated medium channels connected to the outside. The evaporator 10 also has a low-temperature heat medium channel connected to the outside.

[0052] (2) In terms of process, the dilute solution in absorber 1 enters generator 4 via solution pump 2 and solution heat exchanger 3. The high-temperature heat medium flows through generator 4, heating the solution inside and releasing refrigerant vapor, which is then supplied to ejector 5. The concentrated solution in generator 4 enters absorber 1 via solution heat exchanger 3, absorbing refrigerant vapor and releasing heat to the heated medium. The refrigerant vapor in condenser 6 releases heat to the heated medium to form condensate. The refrigerant liquid in condenser 6 is divided into two paths—the first path flows through throttling valve 9 to enter evaporator 10, absorbing heat to form refrigerant vapor and supplying it to absorber 1; the second path flows through booster pump 7 to pressurize and then enters... The steam is absorbed and vaporized in the steam generator 8 and supplied to the ejector 5 as driving steam (working steam). The working steam enters the ejector 5, flows through the nozzle to reduce pressure and increase speed, and forms a low pressure. The refrigerant steam generated by the generator 4 is drawn into the low pressure zone of the ejector 5. After the two steams are mixed, they flow through the diffuser to reduce speed and increase pressure to form medium pressure steam and are supplied to the condenser 6. The high-temperature heat medium provides driving heat load through the steam generator 8 and the generator 4. The heated medium obtains heat load through the absorber 1 and the condenser 6. The low-temperature heat medium provides low-temperature heat load through the evaporator 10, forming a first type of heat-driven jet-absorption heat pump.

[0054] (1) Structurally, in Figure 1 In the first type of heat-driven jet-absorption heat pump shown, a second generator, a second throttling valve, a second solution pump, and a second solution heat exchanger are added. The absorber 1 is provided with a dilute solution pipeline that connects to the second generator 11 via the second solution pump 13 and the second solution heat exchanger 14. The second generator 11 also has a concentrated solution pipeline that connects to the absorber 1 via the second solution heat exchanger 14. The generator 4 is adjusted so that it has a refrigerant vapor channel connected to the low-pressure steam inlet of the ejector 5. After the generator 4 has a refrigerant vapor channel connected to the second generator 11, the second generator 11 then has a refrigerant liquid pipeline that connects to the evaporator 10 via the second throttling valve 12. The second generator 11 also has a refrigerant vapor channel that connects to the low-pressure steam inlet of the ejector 5.
