How many degrees is the warm wind in the Mercedes in winter?

In winter, the indoor warm air temperature is controlled between 65438 08℃ and 25℃. The temperature difference between inside and outside the carriage is generally within 65438 00℃. The most comfortable temperature for human body is 20℃~25℃. Above 28℃, people will feel hot and dry, and below 14℃, people will feel "cold". Therefore, the temperature inside the car is best not to be too high, the temperature difference between inside and outside the car is too large, it is easy to catch a cold when getting off, and the temperature is too low to affect driving comfort.

Don't turn on the warm air immediately after the cold car starts. The heating function of automobile air conditioner is provided by the warm air box of automobile. If the air conditioner wants to blow out hot air, the premise is that the engine temperature must be in a hot state, otherwise the air conditioner will only blow out cold air. There are many car owners who habitually turn on the warm air as soon as they get on the bus. In fact, this is not correct. Because the engine has just started in winter and the temperature of the water tank is very low, the temperature in the car will not rise rapidly after turning on the air conditioner, but it will also slow down the speed of water temperature rise, increase the burden on the engine and prolong the "starting wear time" of the engine.

The correct usage is not to turn on the warm air after starting the engine, and then turn on the warm air when the vehicle has traveled a certain distance and the water thermometer reaches half of the normal water temperature. Just turn on the warm air, please choose a low air volume first, and then turn on the appropriate air volume according to your personal habits after the water temperature reaches normal. In addition, in winter, it is necessary to avoid direct blowing on the face to cause fatigue and affect driving safety. It is generally advisable to blow on the legs and feet. When the legs and feet are warm, the whole body will be warm.
