Why Does Turning on the AC Cause Fogging in Summer?

[OwenDella]

Because the outside temperature is high in summer, and the temperature inside the car is even higher, turning on the AC can more easily cause fogging. Here are some related explanations: 1. Precautions: When cold air meets hot air, fogging is likely to occur. If the fog is not removed in time, it can easily obstruct the view, so it is important to defog promptly and take preventive measures. 2. Defogging Methods: Using the warm air conditioner to blow on the front windshield actually creates a "hot air film" on the glass surface, preventing carbon dioxide from condensing on the glass, which can help defog. Besides using the warm air conditioner for defogging, you can also use some defogging products. For example, some specialized defogging sprays can be evenly applied to the windows before each use, forming a protective film on the glass to prevent fogging.
