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 high-pressure pump 12 via a refrigerant liquid pipeline. The steam generator 13 is connected to the high-pressure steam inlet of the ejector 14 via a refrigerant steam channel. The evaporator 9 is connected to the low-pressure steam inlet of the ejector 14 via a refrigerant steam channel. The ejector 14 is connected to the absorber 6 via a medium-pressure refrigerant steam channel.

[0033] (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 high-temperature heat medium flows through the high-temperature generator 5, heating the solution inside and releasing refrigerant vapor. After being pressurized and heated by the compressor 15, it is supplied to the high-temperature condenser 10.
