<P>PROBLEM TO BE SOLVED: To provide a heat pump system using waste heat capable of further improving COP by sufficiently recovering enthalpy of a refrigerant on the high pressure side of a compressor and using the enthalpy to operate an absorption type heat pump circuit, while using waste heat of a prime mover as a heat source of a regenerator. Ž<P>SOLUTION: The heat pump system using waste heat includes an absorbing solution branch supply means 17. The absorbing solution branch supply means 17 supplies a portion of absorbing solution B made to flow out from an absorber 7 of the absorption type heat pump circuit Y to a solution heat exchanger 15 for performing heat exchange with the absorbing solution B from which a part of a refrigerant A is separated after regeneration by the regenerator 3 and which is returned to the absorber 7 and then, supplies the portion of the absorbing solution B to the regenerator 3; and supplies a portion of the remaining absorbing solution B made to flow out from the absorber 7 to a solution heating regenerator 12 for exchanging heat with a refrigerant A on the high pressure side of the compressor 2 in a compression type heat pump circuit X and then, merges the portion of the remaining absorbing solution B in the absorbing solution B made to flow out from the regenerator 3.
