The invention provides a technology capable of suppressing friction loss of a rotating electric machine. A temperature adjustment system for a vehicle is provided with: a first temperature adjustment circuit that adjusts the temperature of a motor and a generator; a second temperature adjustment circuit that adjusts the temperature of the power conversion device; and a heat exchanger that exchanges heat between the first temperature adjustment medium and the second temperature adjustment medium. The second temperature adjustment circuit is provided with: a first heat sink that exchanges heat between the second temperature adjustment medium and the outside air; a first branch flow path of a second temperature adjusting medium bypassing the heat exchanger; a second branch flow path of a second temperature adjusting medium passing through the heat exchanger; and a valve device that adjusts the flow rate of the second temperature adjustment medium to the second branch flow path.
