Fuel Consumption When Running AC While the Car is Stationary?

[StEsther]

If you run the air conditioning while the car is idling, the fuel consumption is approximately 3 liters per hour. It is not recommended to do this as it can lead to increased carbon deposits in the engine, which is harmful to the engine. When the car's air conditioning is cooling, the engine needs to be running; otherwise, the air conditioning cannot provide cooling. Principle: When the car's air conditioning is cooling, the compressor clutch engages, and the engine drives the compressor. The compressor continuously compresses the refrigerant and delivers it to the evaporator. Refrigerant: The refrigerant expands and absorbs heat in the evaporator, cooling it. The cooled evaporator then cools the air blown by the blower, allowing the car's air conditioning vents to blow cold air. The refrigerant used in car air conditioning is R134a, which needs to be replenished periodically.
