Method and device for improving indoor air quality using window

摘要

Disclosed herein is a method and a device for improving indoor air quality (IAQ) using a window. The indoor air quality is automatically controlled so that a contaminant content of air is maintained at or below an allowable limit, and the evaluated indoor air quality is numerically displayed. The method, compatible with various types of windows, comprises generating hydroxyl radicals (—OH) in an indoor space to decompose contaminants and thus remove the contaminants, measuring contents of the indoor contaminants and numerically displaying the measured contents, forcibly exhausting contaminated indoor air when the content of contaminants is at or above an allowable limit, and stopping exhaustion of air when the content is at or below the allowable limit, so that the indoor air quality is maintained at a suitable state and improved.
