Does Using Recirculated Air Consume More Fuel?

[DelLondyn]

Using recirculated air does consume more fuel. The reasons are as follows: Reason 1: Theoretically, using any electrical appliance will increase fuel consumption. Reason 2: When the system is working, it sends the cold air inside the car directly to the compressor for cooling, which can cool the car faster. Although this consumes less electricity, it still increases fuel consumption. Information about recirculated air is as follows: Function: The main purpose of recirculated air is to promptly and effectively block external dust and harmful gases from entering the car, such as when driving through smoke, dust, areas with strong odors, or in heavy traffic, to prevent harmful exhaust emissions from the vehicle ahead. Do not use it for extended periods: The recirculated air function can cool the car quickly. However, if it is used for a long time without fresh air intake, the windows may fog up easily, and the air inside the car can become stale over time.
