Under the high temperature environment, the interior decoration in a narrow space can accelerate aging, and toxic and harmful pollutants such as aldehyde ketone substances, VOC and the like can accelerate volatilization, so that when a human body is in the environment, the high temperature and the peculiar smell can cause people to feel uncomfortable, and the working efficiency and physical and mental health of people are greatly influenced.
