The invention discloses an absorption-compression-type dual-purpose second species heat pump system, which comprises a cryogen pipeline system and a solution pipeline system. The cryogen pipeline system comprises a condenser, a first cryogen pump, an evaporator, a compressor, and a second cryogen pump. The solution pipeline system comprises a generator, a second absorber, a first absorber, a first solution heat exchanger, a first throttling element, a second solution heat exchanger, a second throttling element, and a solution pump. Compared with a traditional dual-purpose absorption type second species heat pump system, the invention is characterized in that the gas state cryogen outlet of the evaporator is not directly connected with the gas state cryogen inlet of the second absorber, instead, is connected to the air inlet of the compressor, and the outlet vent of the compressor is connected to the gas state cryogen inlet of the second absorber, resulting in running features different from those of the traditional dual-purpose absorption type second species heat pump system, namely, the gas state cryogen is compressed by the compressor, so that the absorption pressure of the second absorber is directly improved, and both the pressure and the heat supply temperature of the first absorber are improved.
