Does the air conditioning not cool when the car is not started?

When the car is not running, the air conditioning does not cool, it only blows air. Here is some relevant information about air conditioning cooling: 1. Car air conditioning: An air conditioning device installed in a car that can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. Air conditioning has become one of the indicators to measure whether a car is fully equipped. 2. Air conditioning system: Generally includes a cooling device, heating device, and ventilation device. This integrated system makes full use of the limited space inside the car, with a simple structure and easy operation, making it a popular modern car air conditioning system internationally.
I've been driving for almost twenty years and often encountered this issue. The air conditioning definitely doesn't cool when the car isn't running because the AC compressor is driven by the engine belt. If the engine isn't turning, the compressor won't work, and there's simply no cold air. The fan might still be blowing loudly, but it's just circulating natural air or hot air. In the summer, when you're parked on the roadside waiting for someone, hoping to cool down a bit, you end up feeling unbearably stuffy. I suggest not running the fan for too long when the engine is off to avoid draining the battery, which could lead to trouble starting the car later. Once, I was waiting for a friend at a highway rest stop, and the battery nearly died, almost leaving me stranded—I had to get help from a mechanic. Regularly checking the car battery and AC system is also a good practice to prevent these minor annoyances.
