Detailed implementation method:

[0046] 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.

[0047] Figure 1 The first type of compression-ejection-absorption heat pump shown is implemented as follows:

[0048] (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 throttle valve, an evaporator, a compressor, a high-temperature heat exchanger, and an expander; 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 also has a refrigerant liquid pipeline connected to the steam generator 8 via the booster pump 7; the steam generator 8 also has a high-pressure... The refrigerant vapor passage connects to the high-pressure steam inlet of ejector 5. The condenser 6 also has a refrigerant liquid pipeline connected to the evaporator 10 via a throttle valve 9. The evaporator 10 also has a refrigerant vapor passage connected to the compressor 11. The compressor 11 also has a refrigerant vapor passage connected to the expander 13 via a high-temperature heat exchanger 12. The expander 13 also has a refrigerant vapor passage connected to the absorber 1. The high-temperature heat exchanger 12, the steam generator 8, and the generator 4 also have high-temperature heat medium passages connected to the outside. The absorber 1 and the condenser 6 also have heated medium passages connected to the outside. The evaporator 10 also has a low-temperature heat medium passage connected to the outside. The expander 13 is connected to the compressor 11 and transmits power.

[0049] (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 compressor 11; the second path flows through booster pump 7 to boost pressure and then enters steam generator 8 to absorb heat and vaporize, providing it to ejector 5 as driving steam (working steam). The working steam enters ejector 5, flows through nozzles to reduce pressure and increase speed, forming a low pressure. The refrigerant vapor generated by generator 4 is drawn into the nozzles. In the low-pressure zone of ejector 5, the two steam streams mix and flow through diffuser to reduce speed and increase pressure, forming medium-pressure steam, which is then supplied to condenser 6. The refrigerant steam discharged from evaporator 10 flows through compressor 11 to increase pressure and temperature, flows through high-temperature heat exchanger 12 to absorb heat and increase temperature, flows through expander 13 to reduce pressure and do work, and is then supplied to absorber 1. The high-temperature heat medium provides driving heat load through high-temperature heat exchanger 12, steam generator 8, and generator 4. The heated medium obtains heat load through absorber 1 and condenser 6. The low-temperature heat medium provides low-temperature heat load through evaporator 10. The mechanical energy output by expander 13 is supplied to compressor 11 as power, or the mechanical energy output by expander 13 is supplied to compressor 11 and external components as power, or expander 13 and external components jointly supply power to compressor 11, forming a first-type compression-ejection-absorption heat pump.
