VEHICLE TEMPERATURE ADJUSTMENT SYSTEM

A vehicle temperature adjustment system includes a first temperature adjustment circuit, a second temperature adjustment circuit, a heat exchanger configured to perform heat exchange between the first temperature adjustment medium and the second temperature adjustment medium, a first temperature sensor configured to detect a temperature of the first temperature adjustment medium flowing into the heat exchanger, a second temperature sensor configured to detect a temperature of the first temperature adjustment medium flowing out of the heat exchanger, a third temperature sensor configured to detect a temperature of the second temperature adjustment medium flowing into the heat exchanger, and a detection unit configured to detect an abnormality in the heat exchanger based on each detection value of the first temperature sensor, the second temperature sensor, and the third temperature sensor.
