It is about an air purification device using solar energy that can reduce air pollution.

Recently, interest in indoor air quality is increasing due to fine dust as well as various organic compounds, including formaldehyde, which causes sick building syndrome, and harmful substances such as radon, carbon dioxide, and carbon monoxide.

As a result, air purifiers and indoor ventilation devices are commonly available not only in multi-use facilities such as buildings, factories, subways, and underground shopping malls, but also in ordinary homes.

In addition, in the case of multi-use facilities, there is usually a ventilation hole in the ceiling, and a blower and air duct for discharging indoor air and sucking in external air are installed on the ceiling.

However, these devices can actually cause indoor air quality to deteriorate when the outdoor fine dust concentration is high.

To prevent this, air purification devices that sterilize harmful substances in the air using UV-B lamps have been used in the past. However, in the case of these devices, the lifespan of the lamps is short, about 6 months, so lamp replacement costs are constantly incurred. A problem occurred.

Accordingly, there is a need for the development of technology that can sterilize air without a separate lamp and reduce maintenance and management costs.
