Abstract: A heat pump system using waste heat has a compression heat pump circuit that uses the shaft output of a power engine as a power source for a compressor for compressing refrigerant, and an absorption heat pump circuit using waste heat of the power engine as a heat source for a regenerator for heating absorbing liquid, refrigerant vaporized in the compression heat pump circuit is circulated to an absorber of the absorption heat pump circuit, the refrigerant is separated after regenerated by the regenerator, and the separated refrigerant is circulated in the compression heats pump circuit. The absorption heat pump circuit has a reverse pump R in a return pipe for absorbing liquid from the regenerator to the absorber, and the rotation energy of the reverse pump R can be withdrawn by a circulation pump P for the absorbing liquid.
