Can I Turn on the Air Conditioning While the Car is Parked?

[StIsla]

It is not recommended to turn on the air conditioning while the car is parked. The reasons are as follows: 1. Impact on engine lifespan: When idling with the air conditioning on, the engine runs at a low speed, causing the oil pump pressure to be too low. This results in insufficient lubrication between the engine's friction surfaces, accelerating wear. Additionally, when the engine speed is very low, it can lead to low intake pressure. In this case, the engine will increase the throttle opening, thereby increasing fuel injection, which may cause incomplete combustion of gasoline, leading to carbon buildup in the combustion chamber and shortening the engine's lifespan. Ultimately, this can cause issues such as difficulty starting the car, poor acceleration, and increased fuel consumption. 2. Adverse effects on human health: Incomplete combustion of gasoline in the cylinders produces high concentrations of carbon monoxide. This carbon monoxide gas can enter the car through the air conditioning's external circulation, potentially causing carbon monoxide poisoning, which may lead to intoxication or even death of the occupants.
