How much fuel does a car consume when idling with the air conditioning on for one hour?

[DeAdriel]

When a vehicle idles with the air conditioning on for one hour, it consumes approximately 1-1.5 liters of fuel. Below is additional information on why a car's air conditioning may stop cooling after running for half an hour: 1. Internal damage: Severe internal wear of the compressor can prevent it from functioning properly. 2. Oil contamination: The presence of oil stains at connection points or seams indicates refrigerant leakage, requiring re-tightening or replacement of related components. 3. Circuit system failure: Circuit system malfunctions are also a common reason for the car's air conditioning compressor not working properly. You can check if the circuit is functioning smoothly, inspect the temperature sensor solenoid valve, and look for other potential faults. The suction pipe surface temperature of the compressor is lower than normal, appearing damp and cold (commonly referred to as sweating).
