In-vehicle absorption heat pump device

An in-vehicle absorption heat pump device comprising:

• 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, and a heater that heats 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;
• a first flow passage through which the concentrated absorbent separated in the gas-liquid separation unit flows to the absorber;
• a second flow passage branching from the first flow passage, and through which the concentrated absorbent separated in the gas-liquid separation unit flows to the heater;
• a pump disposed on an upstream side of a branch portion to the second flow passage in the first flow passage, and circulating the concentrated absorbent inside the regenerator;
• and
• a storage tank that stores both the diluted absorbent discharged from the absorber and the refrigerant discharged from the evaporator, wherein
• the storage tank is integrally provided below both the absorber and the evaporator, and communicates with both the absorber and the evaporator.
