1、为什么有说冬天为汽车除雾，用冷气(空调)比用热风冷风效率好？

2、一年四季也用用冷气。有说常用汽车空调，可减少空调出无病机会，真的吗？何觧？

When using cool air to clean the fog, cool air evaporates the fog on the glass. At the same time, cool air can reduce the temperature difference between inside and outside of the glass, which can stop the fog forming process on the glass.

Warm air can evaporate the fog on the glass too. What is the difference between using cool air and warm air?

Cool air can reduce the temperature difference between the two sides of the window.

What is the difference between cool air condition air and warm air itself?

but air condition works as a humidifier as well.

人呼出来的热气被空调吹出来的冷气推开了，玻璃上的小雾也被制冷并在流动的冷风下挥发了。暖气接近不了玻璃，所以，玻璃上就没有冷凝的水雾了。打开外循环，并加热，空调加热的空气流入车内，虽然温度高，但水份含量低，所以前玻璃上也没有冷凝。雨天除外，水份含量高，要打点冷空调。

开冷气，调溫度最热，不用5秒就能去雾

[:-Q]cool dry air condition air, but hot wet air

I thought the air comes from the same source. Why

hot air carries moisture

冷气会在玻璃上凝集么？
