How much fuel is consumed when idling with the air conditioning on for one hour?

[StJaxson]

Running the air conditioning consumes approximately 0.8L/H of fuel. Below are some tips for using car air conditioning effectively: Ventilate before turning on the AC: After the car has been exposed to prolonged sunlight, open all four doors and the sunroof for 3 minutes to allow air circulation. This quickly reduces the interior temperature, making the AC cooling more effective when turned on. Use the recirculation mode wisely: Recirculation mode blocks hot outside air, creating a sealed space inside the car where air circulates rapidly under the AC's effect for quick cooling. Once the interior temperature drops, it's recommended to switch to fresh air mode every 30 minutes to purify the cabin air, then switch back to recirculation after 5 minutes. Turn off the AC in time: Turn off the air conditioning 5 minutes before parking. This protects the engine and saves fuel.
