If the air-conditioning temperature fed back by the in-car temperature sensor does not reach the set temperature, and the refrigerator temperature fed back by the in-car refrigerator temperature sensor reaches the set temperature, the three-way solenoid valve closes the refrigerator channel; the refrigerator stops cooling, and the air-conditioning continues cooling; 005.
