With the arrival of intense heat, many conductors are looking for creative ways to keep the interior of the car cooler. However, few know that the answer may be on a discreet car button, and it makes all the difference when the thermometers shoot.
The button in question is marked by a circular arrow inside a car and serves to activate air recirculation. Located usually with the climate control system, it is a simple but highly effective tool for maintaining comfort and saving energy.
What does the recirculation button do?
According to RACE (Real Automóvil Club de España), the recirculation button prevents the outer air from entering the cabin, reusing the air that is already inside. This mechanism has four clear advantages: it cools faster, avoids bad odors, protects against polluted air and can still help reduce the energy consumption of the climate control system.
On very hot days, using this button helps to accelerate the cooling process, preventing the system from having to work with air at 35 or 40 degrees from abroad.
How does the system work?
Traditional air conditioning captures the outer air, cools it through a soda circuit and sends it to the cabin. On hot days, this process becomes slower and requires more system effort. With activated recirculation, the already partially cold inner air is again enjoyed, which makes cooling faster and more efficient.
An ally in summer, in moderation
Despite the benefits, the recirculation button should be used in moderation. Keeping out outer air entrances closed for a long time can addict the inner air, especially if there are several people in the car.
According to the same source, the ideal is to activate recirculation during the first 10 to 15 minutes of travel to accelerate the cooling and then unacceptive it, allowing for new and fresh air.
Attention to air quality
Some more modern models already include air quality sensors that automatically activate this system whenever they detect pollutants abroad. In these cases, the recirculation button can work without the driver noticing.
Still, it is important to maintain attention to the environment in the car. A addicted air can cause discomfort, drowsiness or even make visibility difficult if the glasses start to embody.
In winter, caution redoubled
Although it is useful in summer, the recirculation button should be avoided in the colder months. On low temperature days, this mode can cause the glass to embody, especially if there is humidity in the air, which compromises driving safety.
Therefore, as explained, it is advisable to use this feature only when necessary, and always for short periods.
A simple gesture with real impact
Most drivers are unaware of the true potential of the car’s recirculation button. It is a simple, practical solution and already within everyone’s reach that improves comfort and contributes to the energy efficiency of the vehicle.
In a summer where the thermometers promise not to give respite, knowing how to use this small button in the car can make all the difference, and prevent the warmest days from becoming a real sauna on wheels.
