Better practice: to arrive at the station more than ten minutes before the close, so that can open the air conditioning pipe temperature warming, clear * and external temperature difference, and then maintain the relative dry air conditioning system software, prevent Aspergillus flavus breeding. And should also start the car for two or three minutes, after the engine is moistened, and then turn on the air conditioning.

That's not the right thing to do, because the temperature inside the car is higher than the temperature outside the window, so it doesn't actually work very well.

Because the inner circulation is the circulation system of gas in the car, the oxygen content in the car is slowly reduced. When the gasoline in the cylinder is not ignited fully, the carbon monoxide and carbon dioxide will flow into the car, causing the gas in the car to get worse and worse. Therefore, it is proposed that car buyers should open the internal circulation for a while when applying air conditioning, and then convert to the external circulation to start the effect of ventilation.
