The high-temperature heat exchanger 11 is connected to the expander 12. The expander 12 also has a refrigerant vapor channel connected to the high-temperature condenser 13. The high-temperature condenser 13 also has a refrigerant liquid pipeline connected to the evaporator 9 via the throttle valve 14. The high-temperature condenser 13 also has a refrigerant liquid pipeline connected to the steam generator 16 via the high-pressure pump 15. The steam generator 16 also has a refrigerant vapor channel connected to the high-pressure steam inlet of the ejector 17. The evaporator 9 also has a refrigerant vapor channel connected to the low-pressure steam inlet of the ejector 17.

The concentrated solution from the high-temperature generator 5 enters the absorber 6 via the second solution heat exchanger 4, absorbing refrigerant vapor and releasing heat to the heated medium. The dilute solution from the absorber 6 enters the low-temperature generator 1 via the solution heat exchanger 3. The refrigerant liquid flows through the low-temperature generator 1, heating the solution inside and releasing refrigerant vapor. The refrigerant vapor in the low-temperature condenser 7 releases heat to the cooling medium to form a refrigerant liquid.

After the two streams of steam mix, they flow through the diffuser to reduce speed and increase pressure, forming medium-pressure steam, which is then supplied to the absorber 6. The high-temperature heat medium passes through the high-temperature generator 5 and the high-temperature heat... The heat exchanger 11 and the steam generator 16 provide high-temperature driving heat loads. The heated medium obtains medium-temperature heating loads through the absorber 6 and the high-temperature condenser 13.
