Why does the auto start-stop not work when the air conditioning is on?

[Lilliana]

The reason why the auto start-stop does not work when the air conditioning is on is that the temperature inside the car is still relatively high. Therefore, to ensure passenger comfort, the auto start-stop system will stop functioning. If the interior temperature reaches the level set by the air conditioning, the auto start-stop system will resume operation. Many cars are equipped with an auto start-stop system, which helps save fuel and reduce exhaust emissions. The cooling principle of a car's air conditioning system: When cooling is activated by pressing the AC button, the compressor clutch engages, allowing the car's engine to drive the compressor. The compressor continuously compresses the refrigerant and delivers it to the evaporator. The refrigerant expands and absorbs heat inside the evaporator, cooling it. The cooled evaporator then cools the air blown by the blower, resulting in cold air being emitted from the air vents.
