The present invention relates to a vehicle air-conditioning apparatus having a circulation path for a working fluid between an evaporating unit and a condensing unit. The vehicle air-conditioning apparatus comprising a thermoelectric module according to the present invention comprises: a first heat exchange unit including an evaporating unit which thermally contacts one side of the thermoelectric module, a liquid chamber formed at one end of the evaporating unit, and a gas chamber formed at the other end of the evaporating unit; a second heat exchange unit having a heat sink which thermally contacts the other side of the thermoelectric module; a vacuum unit interposed between the gas chamber and the condensing unit such that the pressure difference generated in the circulation path by the vacuum unit circulates the working fluid; and a pumping unit interposed between the condensing unit and the liquid chamber to transfer the working fluid circulating through the condensing unit. The vehicle air-conditioning apparatus according to the present invention transfers the working fluid using the driving force generated in the vacuum unit and the pumping unit arranged in the circulation path of the working fluid, the capillary force of a liquid working fluid generated in a transfer channel of the evaporating unit, the pressure difference, the pump, etc., thereby improving the performance of the vehicle air-conditioning apparatus. |
