In winter, fog appears on the window, which can be removed by turning on the warm air. In summer, fog will appear on the window after heavy rain, and it can be removed by turning on the air conditioner. Why? In winter, the temperature outside is relatively low, and the heating in the car will liquefy into fog and attach to the glass when it meets cold glass. After the heating is turned on, the heating will increase the temperature of the glass, so that there is no temperature difference between the fog in the car and the glass, and there will be no fog. . In summer, if there is fog inside, it means that the temperature outside is low and the temperature inside is high. When the water vapor is cold, it becomes small water droplets "fog". When the cold wind is turned on, the "fog" evaporates into water vapor and is out of sight. You should know that it is very fast to increase air flow and water evaporation.
