Second-kind absorbing type heat pump

The invention discloses a second-kind absorbing type heat pump which comprises a generator, a condenser, an absorber, a heat exchanging assembly and an evaporator. A first heat exchanging pipeline and a second heat exchanging pipeline are arranged in the absorber and communicate with a driving heat source and a heated medium of a static heat exchanging assembly correspondingly, and the heated medium in the heat pump is heated up three times, specifically, at the first time, the heated medium is heated up by steam liquidating heat releasing of the condenser, at the second time, the heated medium is heated up by the driving heat source flowing out from the absorber, and at the third time, the heated medium is heated up by a solution in the absorber; that is to say, heating energy of the heated medium derives from steam liquidating heat energy in the condenser and heat energy released from diluting of the concentrated solution in the absorber; energy released from steam liquidating in the condenser can be recycl
