How much fuel does running the car air conditioner for one hour consume?

[Ida]

It consumes approximately 2~3 liters of fuel per hour. The engine remains at idle speed, resulting in relatively low fuel consumption. Here are the details: 1. Engine idling: Engine idling consumes a significant amount of fuel. When idling, the engine only drives the air conditioning compressor, and prolonged operation at high temperatures can lead to dangerous accumulations of carbon dioxide and carbon monoxide inside the vehicle. 2. Precautions: Smoking while the car air conditioner is on prevents smoke from being promptly vented outside, which can harm the eyes and respiratory system. Avoid adjusting the temperature excessively; setting the air conditioner to the lowest temperature for rapid cooling can directly affect the human endocrine system. Prolonged exposure to excessively low temperatures may cause symptoms such as leg pain and general chills. It is recommended to maintain a temperature difference of 5-6℃ from the outside environment.
