Does the car consume fuel when idling in P gear with the air conditioning on?

When a car is idling in P gear with the air conditioning on, it consumes approximately 1-2 liters of fuel per hour. Below are specific details about prolonged idling in P gear with the air conditioning on: 1. Carbon monoxide poisoning: In a parked state, if the air is not circulating and the vehicle's exhaust is not promptly expelled, it may seep into the car, leading to carbon monoxide poisoning. When the air conditioning is on, the doors and windows are generally closed. If the air conditioning is set to recirculate, even without carbon monoxide poisoning, the oxygen inside the car will gradually deplete, potentially causing suffocation. 2. Increased fuel consumption: The formation of carbon deposits can increase the car's fuel consumption. Carbon deposits in the combustion chamber can raise fuel consumption by 4%-5%. The air conditioning compressor is driven by the engine. When the engine is off, only the blower operates, which is powered by the battery. Prolonged idling with the air conditioning on can drain the battery, and in severe cases, the car may even fail to start.
