To provide a heat medium circulation device for a vehicle which can restrain electrical power consumption when air-conditioning is used.SOLUTION: A heat medium circulation device for a vehicle comprises a heating circuit around which a first heat transfer medium supplied to a heater core is circulated, a battery temperature control circuit around which a second heat transfer medium supplied to a battery is circulated, a circuit switching valve which switches connection state between the heating circuit and the battery temperature control circuit and a controller which controls the heating circuit, the battery temperature control circuit and the circuit switching valve. The controller includes a prediction part which predicts start of air-conditioning during stop of the air-conditioning and a switching control part which controls the circuit switching valve on the basis of determination result of the prediction part. The switching control part makes the circuit switching valve to opening communication state so that the second heat transfer medium of the battery temperature control circuit is sent to the heating circuit if the prediction part predicts the start of the air-conditioning.SELECTED DRAWING: Figure 1
