Can I turn on the air conditioner when the car is parked?

You can turn on the air conditioner when the car is parked. Theoretically, as long as the car has oil and electricity, the air conditioner can always be on. But in reality, it usually takes about 15 minutes to stop and turn on the air conditioner. There are several reasons:

1. Turning on the air conditioner after parking for a long time can easily lead to carbon monoxide poisoning. There was an experiment, in a closed space, only 20 minutes, air-conditioned cars will have carbon monoxide exceeding the standard. If the air conditioner is turned on for a long time, open the window regularly for ventilation, or switch to the external circulation mode.

2. Increase fuel consumption. When the engine is stopped, it runs at idle speed, resulting in low intake pressure. At this time, the engine will increase the throttle opening, thus increasing the fuel injection.

3, the heat dissipation time is too long, which is harmful to the automobile engine. When the engine stops, it runs at idle speed, resulting in low oil pump pressure, which will lead to insufficient lubrication between engine friction surfaces and accelerate wear. Million car purchase subsidy
