Claim:
1. An in-vehicle absorption heat pump device, comprising: a regenerator for heating an absorbent; an in-vehicle heat source for heating the absorbent in the regenerator; a gas-liquid separator for separating gas phase and liquid phase from the absorbent heated by the in-vehicle heat source in the regenerator so as to relatively increase concentration of the absorbent; a condenser for condensing the gas phase separated from the absorbent to form a condensate; an evaporator for evaporating the condensate condensed in the condenser to form vapor; an absorber for bringing the absorbent in liquid phase relatively concentrated by the separation of the gas phase in the gas-liquid separator in contact with the gas phase evaporated in the evaporator so as to cause the absorbent to absorb the gas phase and be relatively diluted and allow the diluted absorbent to be supplied to the regenerator; an absorbent circulation source for circulating the absorbent in a circulation passage connecting the regenerator, the gas-liquid separator and the absorber; a bypass passage connecting a liquid-phase storing portion of the gas-liquid separator and the regenerator while bypassing the absorber; a bypass transfer source provided in the bypass passage, transferring the absorbent in liquid phase stored in the gas-liquid separator from the gas-liquid separator to the regenerator while bypassing the absorber, and a control unit for controlling an amount of the absorbent to be transferred by the bypass transfer source in accordance with at least one of a request load to the in-vehicle absorption heat pump device by a user, and an amount of radiated heat per unit time of the in-vehicle heat source.
