To provide a vehicle floor cooling/heating device capable of cooling or heating a floor of a cabin.SOLUTION: Provided is a vehicle floor cooling/heating device 10 with a cooling water circuit 20 for cooling or heating a cabin 6 by cooling a floor 7 of the cabin 6 by circulating cooling water or by heating to an appropriate temperature in cooperation with battery heat and for cooling a battery 8 arranged under the floor 7. The cooling water circuit 20 comprises: a battery cooler 23 which is disposed under the battery 8 and which cools the battery 8 with the cooling water; a bypass path 24 for bypassing the battery cooler 23; a selector valve 25 for selecting a state of making the cooling water pass through the battery cooler 23 or a state of making the cooling water pass through the bypass path 24; and a floor heat exchanger 26 for cooling or heating the floor 7. Therein, when the battery 8 is not cooled, the selector valve 25 causes the cooling water to pass through the bypass path 24 and the floor heat exchanger 26 cools the floor 7.SELECTED DRAWING: Figure 1

    【課題】車室の床を冷却するまたは加熱することができる車両用床冷暖房装置を提供する。【解決手段】冷却水を循環させることによって車室6の床7を冷却またはバッテリの熱と協調して適温加熱することによって車室6を冷房または暖房すると共に床7の下方に配置されたバッテリ8を冷却する冷却水回路20を有する車両用床冷暖房装置10であって、冷却水回路20は、バッテリ8の下方に設けられて冷却水によってバッテリ8を冷却するバッテリ冷却器23と、バッテリ冷却器23をバイパスするバイパス経路24と、バッテリ冷却器23に冷却水を通過させる状態、または、バイパス経路24に冷却水を通過させる状態を切り替える切替弁25と、床7を冷却または加熱する床熱交換器26と、を備え、バッテリ8を冷却しない時には、切替弁25によってバイパス経路24に冷却水を通過させて、床熱交換器26によって床7を冷却する。【選択図】図1
