  • In-vehicle absorption heat pump device
    Patent number: 11454431
    Abstract: An in-vehicle absorption heat pump device includes: a regenerator including a gas-liquid separation unit that separates a diluted absorbent containing a refrigerant into the refrigerant and a concentrated absorbent separated from the diluted absorbent; a condenser that condenses a refrigerant vapor separated from the diluted absorbent in the gas-liquid separation unit; an evaporator that evaporates the refrigerant condensed in the condenser; an absorber that causes the refrigerant evaporated by the evaporator to be absorbed into the concentrated absorbent separated from the diluted absorbent in the gas-liquid separation unit; and a storage tank that stores both the diluted absorbent discharged from the absorber and the refrigerant discharged from the evaporator. The storage tank is integrally provided below both the absorber and the evaporator, and communicates with both the absorber and the evaporator.
