Summer weather offers all kinds of and sometimes even bizarre ways to deal with the heat. Portal “AutoVzglyad” talks about one of them.

Warm weather forces drivers to somehow regulate a comfortable temperature in the cabin. Most prefer a standard air conditioner for this. But there are those who prefer to create coolness, so to speak, in a natural way – with the help of car windows that are opened along the way. Specifically, they don’t turn on the car’s climate system, preferring the old-fashioned “windows open method”.

The air conditioner in their concept “drys the air” and causes discomfort in the nasopharynx. And the air coming out of open windows is not. Plus, you won’t catch a cold. Yes, but in the heat of 30 degrees, it must be admitted, you should not expect a special cooling effect from outboard air clouds.

And so, astute car owners have figured out how to avoid a dry throat from the air conditioner while really cooling the interior in the summer heat. They open the windows to let in outside air and turn on the air conditioning at the same time. But at the same time, the adjustments are set to a specific configuration. Cool air is directed only to the feet. This creates a kind of cold “bath” below the level of open windows, filled with cooler air from the air conditioner with a higher specific gravity.

And above the cold layer “walks” warm, but fresh air coming from the windows. In such conditions, people in the cabin breathe it in, while their bodies enjoy the coolness of the air conditioner. Ecologically gifted people will say that open windows increase the air resistance of the body, leading to higher fuel consumption. Like, by the way, and a working air conditioner. That is, it turns out that there is a “double” increase in fuel consumption. But who in Russia looks at such trifles when it is more than 30ºС outside?

And who cares if someone is willing to tolerate an excess of about 0.5 liters of fuel per 100 kilometers for his own comfort? By the way, in this situation it is also curious that such operation of a car air conditioner practically in no way affects its durability. Even with the windows open, even with the windows closed, but when driving the vehicle, the “apartment” is forced to work constantly. Simply because when the car is moving, the incoming outboard air is constantly going through the car’s ventilation system, even by gravity, and it needs to be cooled in any case. That is, windows that are open during operation cannot really affect the life of the air conditioning compressor. Therefore, driving in the heat with the windows down and working the “climate” is a fully justified method of achieving the personal comfort of the car owner.
