How much fuel is consumed when idling with the air conditioning on for 3 hours?
1 Answers
Idling with the air conditioning on for 3 hours consumes approximately 3-4.5 liters of fuel. Below is relevant information: Air conditioning: The air conditioning system mainly consists of components such as the compressor, expansion valve, condenser, evaporator, and blower. Cold air is produced by pressurizing the compressor to liquefy the refrigerant, which then vaporizes, absorbing heat from the air to achieve a cooling effect. Using air conditioning in winter: The warm air used in winter mainly comes from the engine, so it does not consume much fuel. However, summer is different; using the cold air function will definitely consume more fuel. During idling: The vehicle consumes about 2 liters of fuel per hour while idling because the engine is in an idle state with low RPM, resulting in reduced air intake efficiency. Besides fuel consumption and carbon buildup, idling also causes certain environmental pollution.
