Does Using Recirculated Air Consume More Fuel?
1 Answers
Neither recirculated air nor fresh air mode consumes additional fuel; only operating the air conditioning compressor increases fuel consumption. Here are some tips for using car air conditioning effectively: 1. Ventilate before turning on AC: After prolonged exposure to sunlight, open all four doors and the sunroof for 3 minutes to allow air circulation. This quickly reduces interior temperature, making subsequent AC cooling more efficient. 2. Use recirculated air wisely: Recirculation blocks external hot air, creating a sealed space where air rapidly circulates under AC operation for quick cooling. After achieving desired temperature, switch to fresh air mode every 30 minutes for air purification (5 minutes duration), then revert to recirculation. 3. Turn off AC in advance: Shut down the air conditioning 5 minutes before parking to protect the engine and save fuel.
