<p>The purpose of the present invention is to provide a vehicle heat-pump device that can improve the stability of a refrigerant cycle without reducing, as much as possible, the other functions thereof. A vehicle heat-pump device (1) is equipped with the following: an electric compressor (112) that compresses and ejects refrigerant; a high-temperature side water refrigerant heat exchanger (111) that performs heat exchange between a coolant that absorbs heat from the refrigerant and conveys such heat and a high-temperature high-pressure refrigerant ejected from the electric compressor (112); and an internal heat exchanger (115) that performs heat exchange between the coolant that flows into the high-temperature side water refrigerant heat exchanger (111) and the refrigerant that is suctioned by the electric compressor (112).</p> |
