The invention of air conditioner (AC) has undoubtedly saved the world from the heat of summer. The development of AC is an important embodiment of continuous development and perfection of science and technology. This article explains the mechanism of freon pollution from the perspective of chemistry, and enumerates the important role of fluoride in daily life, to eliminates people's misunderstanding of fluorine element. The hardships of extracting fluorine reflect the chemists' research experience of collecting experience from failure and the scientific spirit of pursuing the truth.

Key words: Science popularization of chemistry, Air conditioner, Freon, Fluorine
