TEMPERATURE CONTROL SYSTEM

A temperature control system includes an air-conditioning circuit, a battery temperature adjustment circuit, a heat exchanger, a thermometer, and a controller. The air-conditioning circuit includes a heating unit for heating the air-conditioning heating medium and an air-conditioning flow amount adjustment unit for adjusting the amount of flow of the air-conditioning heating medium. The battery temperature adjustment circuit includes a battery flow amount adjustment unit for adjusting the amount of flow of the battery heating medium. The controller variably controls the amount of flow of at least one of the air-conditioning heating medium and the battery heating medium, depending on a request for increasing the temperature of the battery, a request for heating the cabin of the vehicle, and the temperature of the battery.
