In every car, even those without air conditioning, there is a button that symbolizes an arrow closed in the vehicle’s passenger compartment.

Button for heating the car in one second – that’s what it is
When should air recirculation be used? Enabling this button causes the closure of the air inlet shutters in the ventilation ducts. This means that the ventilation system restricts airflow from outside the car. Note that the fan uses the air from the car and depending on the temperature selected, it can heat or cool it.
Thanks to this process, the air coming from outside the vehicle does not mix with the air inside the car. This closed circuit is useful in many situations: inside a tunnel or when a car emits a lot of exhaust or when there is smoke emitted from a fire. Very often, closing the circuit helps to avoid bad smells from the outside, thus preventing them from entering the car. Air recycling is essential when temperatures drop. In winter, you can warm up your car faster and more efficiently to better deal with frosty mornings. However, it should be remembered that this ventilation system should not be used too long. Switching to an open circuit is necessary to prevent the windows from fogging up. It must be remembered that the air recirculation and lack of fresh air can cause a profusion of humidity.
