PURPOSE: A one-stage compression-absorption heat pump system and a two-stage compression-absorption heat pump system are provided to reduce damage due to liquid compression of a compressor by removing absorbent liquid included in a refrigerant which flows in the compressor through a desiccant rotor. CONSTITUTION: A one-stage compression-absorption heat pump system comprises an expansion device(150), a desorber(110), a compressor(130), a pump(140), an absorber(120), and a desiccant rotor(170). The expansion device expands a refrigerant-absorbent mixture at high temperature and high pressure and changes to a refrigerant-absorbent mixture at low temperature and low pressure. The desorber induces the refrigerant-absorbent mixture at low temperature and low pressure from the expansion device and evaporates part of the refrigerant from the refrigerant-absorbent mixture. The compressor compresses the refrigerant evaporated from the desorber. The pump pressurizes the refrigerant-absorbent mixture in a dilute solution state with a high pressure solution. The absorber absorbs the refrigerant-absorbent mixture at high pressure, which is discharged from the pump, in the refrigerant at high pressure and high temperature. The desiccant rotor adsorbs absorbent liquid included in the refrigerant at low temperature which flows from the compressor and flows with the refrigerant at high pressure and high temperature.
