Detailed implementation method:

[0045] 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.

[0046] Figure 1 The compression-ejection-absorption heat pump shown is implemented as follows:

[0047] (1) Structurally, it is mainly composed of an absorber, a solution pump, a solution heat exchanger, a generator, an ejector, a condenser, a throttle valve, an evaporator, and a compressor. 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. Externally, there is a working steam channel connected to the high-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 also has a condensate channel connected to the outside. The condenser 6 also has a condensate pipeline connected to the evaporator 8 via the throttle valve 7. The evaporator 8 also has a refrigerant vapor channel connected to the absorber 1 via the compressor 9. The generator 4 also has a high-temperature heat medium channel connected to the outside. The absorber 1 and the condenser 6 also have heated medium channels connected to the outside. The evaporator 8 also has a low-temperature heat medium channel connected to the outside.

[0048] (2) In terms of process, the dilute solution from 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 from generator 4 enters absorber 1 via solution heat exchanger 3, absorbing refrigerant vapor and releasing heat to the heated medium. The external high-pressure working steam enters ejector 5, flows through nozzles to reduce pressure and increase speed, forming a low-pressure environment. The refrigerant vapor generated by generator 4 is drawn into the low-pressure zone of ejector 5. After the two steam streams mix, they flow through diffuser to reduce speed and increase pressure, forming medium-pressure steam, which is then supplied to condenser 6. The refrigerant vapor inside 6 releases heat to the heated medium to form condensate. The condensate discharged from condenser 6 is divided into two paths: the first path flows through throttle valve 7 to reduce pressure and temperature, flows through evaporator 8 to absorb heat and vaporize, flows through compressor 9 to increase pressure and temperature, and then supplies to absorber 1; the second path is discharged to the outside. Working steam provides driving heat load through ejector 5, high-temperature heat medium provides driving heat load through generator 4, external mechanical energy is provided by compressor 9, the heated medium obtains heat load through absorber 1 and condenser 6, and low-temperature heat medium provides low-temperature heat load through evaporator 8, forming a compression-ejection-absorption heat pump.

[0049] Figure 2 The compression-ejection-absorption heat pump shown is implemented as follows:

[0050] (1) Structurally, in Figure 1In the compression-ejection-absorption heat pump shown, a second generator, a second throttle valve, a second solution pump, and a second solution heat exchanger are added. The absorber 1 is equipped with a dilute solution pipeline that connects to the second generator 10 via the second solution pump 12 and the second solution heat exchanger 13. The second generator 10 also has a concentrated solution pipeline that connects to the absorber 1 via the second solution heat exchanger 13. 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 10, the second generator 10 also has a condensate pipeline that connects to the evaporator 8 via the second throttle valve 11. The second generator 10 also has a refrigerant vapor channel that connects to the low-pressure steam inlet of the ejector 5.

[0051] (2) In terms of process, with Figure 1 Compared to the compression-ejection-absorption heat pump shown, the difference lies in the following: the refrigerant vapor generated by generator 4 is provided to the second generator 10 as the driving heat medium. Part of the dilute solution in absorber 1 enters the second generator 10 via the second solution pump 12 and the second solution heat exchanger 13. The refrigerant vapor flows through the second generator 10, heats the solution inside, releases refrigerant vapor, and is supplied to ejector 5. The concentrated solution in the second generator 10 enters the absorber 1 via the second solution heat exchanger 13. The refrigerant vapor flowing through the second generator 10 releases heat and becomes condensate, which is then throttled by the second throttle valve 11 and enters the evaporator 8, thus forming a compression-ejection-absorption heat pump.

[0052] Figure 3 The compression-ejection-absorption heat pump shown is implemented as follows:

[0053] (1) Structurally, in Figure 1 In the compression-ejection-absorption heat pump shown, a second generator, a second throttling valve, and a second solution heat exchanger are added. The absorber 1 is connected to the generator 4 via a dilute solution pipeline through the solution pump 2 and the solution heat exchanger 3. The absorber 1 is then connected to the generator 4 via a dilute solution pipeline through the solution pump 2, the solution heat exchanger 3, and the second solution heat exchanger 13. The generator 4 is connected to the absorber 1 via a concentrated solution pipeline through the solution heat exchanger 3. The generator 4 is then connected to the second generator 10 via the second solution heat exchanger 13. The second generator 10 is then connected to the absorber 1 via a concentrated solution pipeline through the solution heat exchanger 3. The generator 4 is connected to the low-pressure steam inlet of the ejector 5 via a refrigerant vapor channel. The generator 4 is then connected to the second generator 10 via a refrigerant vapor channel. The second generator 10 is then connected to the condensate pipeline through the second throttling valve 11 and the condenser 6. The second generator 10 is also connected to the low-pressure steam inlet of the ejector 5 via a refrigerant vapor channel.

[0054] (2) In terms of process, with Figure 1Compared to the compression-ejection-absorption heat pump shown, the difference lies in the following: the refrigerant vapor generated by generator 4 is provided to the second generator 10 as the driving heat medium.

[0092] (1) Structurally, in Figure 1In the compression-ejection-absorption heat pump shown, a second generator, a second throttle valve, a second solution pump, a second solution heat exchanger, a second condenser, and a second ejector are added. The generator 4, which has a concentrated solution pipeline connected to the absorber 1 via the solution heat exchanger 3, is adjusted so that the generator 4 has a concentrated solution pipeline connected to the second generator 10 via the second solution pump 12 and the second solution heat exchanger 13. The second generator 10 also has a concentrated solution pipeline connected to the absorber 1 via the second solution heat exchanger 13 and the solution heat exchanger 3. The second generator 10 also has a refrigerant vapor channel connected to the low-pressure steam inlet of the second ejector 24, and an external working steam channel connected to the high-pressure steam inlet of the second ejector 24.

[0093] (2) In terms of process, with Figure 1 Compared to the compression-ejection-absorption heat pump shown, the difference lies in the following: the concentrated solution from generator 4 flows through the second solution pump 12 and the second solution heat exchanger 13 into the second generator 10. A high-temperature heat medium flows through the second generator 10, heating the solution inside and releasing refrigerant vapor. The concentrated solution from the second generator 10 flows through the second solution heat exchanger 13 and the solution heat exchanger 3 into the absorber 1. Externally pressurized working steam enters the second ejector 24, flows through nozzles to reduce pressure and increase speed, forming a low-pressure system. The refrigerant vapor emitted from the second generator 10 is drawn into the second... In the low-pressure zone of ejector 24, the two steam streams mix and flow through diffuser to reduce speed and increase pressure, forming medium-pressure steam, which is then supplied to the second condenser 18. The refrigerant steam in the second condenser 18 releases heat to the heated medium to form condensate. The condensate discharged from the second condenser 18 flows through the second throttle valve 11 to reduce pressure and temperature, and then is supplied to the condenser 6. Externally, the second ejector 24 provides the driving heat load, and the high-temperature heat medium provides the driving heat load through the second generator 10, which in turn increases the heating load of the heated medium through the second condenser 18, forming a compression-ejection-absorption heat pump.

[0096] (2) In terms of process, with Figure 1Compared to the compression-ejection-absorption heat pump shown, the difference is that the condensate of the condenser 6 is divided into two paths: the first path flows through the nozzle A to reduce pressure and increase speed, flows through the evaporator 8 to absorb heat and vaporize, flows through the dual-energy compressor B to increase pressure and temperature and reduce speed, and then enters the absorber 1; the second path is discharged to the outside, forming a compression-ejection-absorption heat pump.

[0097] Figure 18 The compression-ejection-absorption heat pump shown is implemented as follows:

[0099] (2) In terms of process, with Figure 3 Compared to the compression-ejection-absorption heat pump shown, the difference is that: the condensate discharged from the second generator 10 flows through the second nozzle C to reduce pressure and increase speed, and then enters the condenser and releases heat; part of the condensate discharged from the condenser 6 is depressurized and increased in speed through the nozzle A, flows through the evaporator 8 to absorb heat and vaporize, flows through the dual-energy compressor B to increase pressure and temperature and decrease speed, and then enters the absorber 1, forming a compression-ejection-absorption heat pump.
