When running at high speed, do you open the inner loop or the outer loop? It's dangerous to make a mistake

have had the experience of running at high speeds. When driving on high speeds, should they use the inner loop or the outer loop? Many car owners do it differently. Some car owners think that when driving on high speeds, the internal circulation is enough, so that the air in the car can be fully circulated, and it will also help the temperature in the car to rise rapidly.

In fact, there is a big difference between the inner loop and the outer loop when driving at high speed. First of all, it must be clear that driving at high speed cannot only use the inner loop, and the inner and outer loops must be driven together. In winter, the temperature is relatively low. When running at a high speed, car owners should first turn on the internal circulation to allow the air in the car to circulate and the temperature in the car can also rise rapidly. After

waits for the temperature in the car to rise, the owner needs to close the inner loop and open the outer loop. Because the vehicle is traveling at high speeds at a faster speed, the owner cannot open the windows. At this time, opening the outer loop can play a role in ventilation. Driving on high speeds for a long time, many car owners will have hypoxic reactions, and the outer loop needs to be opened at this time.

Some car owners never open the outer loop when running at high speeds. The sunroof and windows in the car are also closed. After a few hours of opening, the car owner will feel dizzy, chest tightness, shortness of breath, and even motion sickness. The biggest reason for this problem is that the car owner has not done a good job of ventilation. At this time, the car owner turns on the external circulation, and the problem of brain hypoxia can be quickly alleviated.

All in all, when driving at high speeds, both the inner and outer loops must be opened. The different order will also affect the ventilation effect in the car and the health of the owner. Now that the temperature in winter is low, car owners must remember to turn on the outer loop when running at high speeds, and don't let the carbon dioxide concentration in the car be too high.
