The high-temperature condenser 10 is connected to the low-temperature generator 1 via a refrigerant liquid pipeline. The low-temperature generator 1 is then connected to the evaporator 9 via a refrigerant liquid pipeline through a throttle valve 11. The high-temperature condenser 10 is also connected to the steam generator 13 via a refrigerant liquid pipeline through a high-pressure pump 12. The steam generator 13 is also connected to the high-pressure steam inlet of the ejector 14 via a refrigerant steam channel. The evaporator 9 is also connected to the low-pressure steam inlet of the ejector 14 via a refrigerant steam channel. The ejector 14 is also connected to the absorber 6 via a medium-pressure refrigerant steam channel.

The low-temperature condenser 7 is connected to the outside via a cooling medium channel. The evaporator 9 is also connected to the outside via a low-temperature heat medium channel.

[0031] (2) In terms of process, the concentrated solution from the low-temperature generator 1 enters the high-temperature generator 5 via the solution pump 2, solution heat exchanger 3, and second solution heat exchanger 4.

The refrigerant liquid from the low-temperature condenser 7 is pressurized by the low-pressure pump 8 and enters the evaporator 9 to absorb heat and vaporize. The refrigerant vapor from the high-temperature condenser 10 releases heat to the heated medium to form refrigerant liquid. The first path of refrigerant liquid discharged from the high-temperature condenser 10 flows through the generator 1 to release heat and cool down, and then flows through the throttling valve 1. The refrigerant liquid discharged from the high-temperature condenser 10 is depressurized and cooled, and then enters the steam generator 13 to absorb heat, heat up, and vaporize. The refrigerant steam discharged from the steam generator 13 is provided to the ejector 14 as working steam. The working steam enters the ejector 14, flows through the nozzle to depressurize and increase speed, and forms a low pressure. The refrigerant steam generated by the evaporator 9 is drawn into the low-pressure zone of the ejector 14. After the two steams are mixed, they flow through the diffuser to depressurize and increase pressure to form medium-pressure steam and are supplied to the absorber 6.
