In winter, select internal circulation or external circulation for internal defogging. Open internal circulation or external circulation for window fogging
Should I use internal circulation or external circulation when the windows are foggy in winter? As long as it is winter, it is also very common for the window glass to fog, and what the driver friends dislike most is that the glass is fogged, which will affect the line of sight. So when the window fogs in winter, should we use internal circulation or external circulation?
In winter, internal circulation or external circulation shall be selected for defogging in the vehicle
Choose the external circulation as like as two peas. The outer loop of the air conditioner means a channel between the outside and the outside of the car, which is the room temperature becomes the same as the external air. The demisting effect of external circulation of air conditioner is remarkable, which can be effective in a few minutes. The use of heating for defogging not only consumes fuel, but also the closed environment and hot air will make car owners feel sleepy.
However, the disadvantage of the external circulation of the air conditioner is that it will be colder indoors after a long time of use. If we feel cold, we can switch to the internal circulation of the air conditioner to lock the temperature. If it is really too cold, we can also turn on the warm air, and then use the internal and external circulation alternately. Car owners only need to combine flexibly according to their own needs.
