A regenerative third type absorption heat pump, in any of the regenerative third type absorption heat pumps of claims 4-19, adding a re-absorption-evaporator, a re-increasing device, and increasing The evaporator, the additional throttle valve, the re-refrigerant liquid pump or the second throttle valve, the re-increasing solution pump and the re-increasing solution heat exchanger, and the second absorber (4) has a dilute solution line The second solution heat exchanger (12) and the third solution heat exchanger (13) are connected to the third absorber (5) to be adjusted to a second absorber (4) having a dilute solution line through a re-increasing solution pump (M) And the re-increasing solution heat exchanger (N) is in communication with the re-intensifier (K), the re-intensifier (K) and the dilute solution line via the re-increasing solution heat exchanger (N) and the re-absorption-evaporator (J) connected, re-absorption-evaporator (J) and then a dilute solution line is connected to the third absorber (5) via the second solution heat exchanger (12) and the third solution heat exchanger (13), The condenser (15) has a refrigerant liquid pipeline connected to the evaporator (16) through the throttle valve (17) to be adjusted into a condenser (15), and a refrigerant liquid pipeline is passed through the throttle valve ( 17) Connect with the re-increasing evaporator (0), and then increase the evaporator (0). Then the refrigerant liquid line is connected to the evaporator (16) through the re-increase throttle valve (P). The evaporator (16) has The refrigerant vapor passage is connected to the second absorber (4) to be adjusted to be an evaporator (16) having a refrigerant vapor passage communicating with the re-absorption-evaporator (J), and then increasing the evaporator (0) and the refrigerant vapor passage. It is connected with the second absorber (4), and the condenser (15) is provided with a refrigerant liquid pipeline, and then the second throttle valve is connected with the re-absorption-evaporator (J) to increase the absorption-evaporator (J). Further, the refrigerant vapor passage is connected to the re-intensifier (K), or the evaporator (16) is connected with the refrigerant liquid pipeline through the re-refrigerant liquid pump (L) and the re-absorption-evaporator (J). The re-absorption-evaporator (J) is further connected to the re-intensifier (K) by the refrigerant vapor channel, and the re-absorber (K) and the heated medium line are connected to the outside, and the evaporator is further increased (0). The residual heat medium pipe is connected to the outside to form a regenerative third type absorption heat pump.
