Method and device for improving indoor air quality using window

Abstract

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.

Description

technical field [0001] The present invention relates to a method and apparatus for improving indoor air quality (IAQ) using windows, wherein the indoor air quality is automatically controlled by windows so as to maintain the concentration of pollutants in the air at or below allowable limit values, and digitally displays the estimated Indoor air quality. Background technique [0002] As known to those skilled in the art, traditional windows and doors only function to be opened or closed for ventilation, daylighting and crime prevention. Traditionally, since indoor air is ventilated only by manually or automatically opening or closing windows, it is impossible to ventilate or discharge various harmful pollutants generated if the windows are completely closed when no one is inhabited or at night to prevent crimes. Indoor substances, pollutants present indoors will cause some problems. [0003] Traditionally, of course, air purifiers are sometimes used to improve indoor air q...

AI Technical Summary

Problems solved by technology

[0013] Although the traditional method of improving air quality has the advantage of saving energy due to the use of variable air volume (VAV) regulation, the problem with the traditional method is that the indoor air is easily polluted due to the entry of outside air containing pollutants, and due to Installation costs are high and uneconomical

Also, in constant air volume (CAV) regulation method, room air is continuously changed to provide pleasant room air, but the problem is that high energy consumption cannot be avoided

In particular, the problem with these conventional air conditioning methods is that the maintenance costs are high

[0014] Also, in traditional products for improving air quality with disinfection, deodorization and air purification functions, only sensors can be used for detection, and the detected air quality cannot be verified or maintained, so occupants cannot directly monitor the air quality

Therefore, it is impossible to effectively maintain indoor air quality
