Abstract:
As an important factor ensuring the indoor thermal comfort,air relative humidity may influence the indoor air quality.Based on the impact of air humidity on acceptable indoor air quality percentage,this paper presented the impact of air humidity on chemical pollutants (formaldehyde and ozone) and biologic contaminations.The research results showed that appropriate increase of relative humidity can decrease ozone concentration in the room,contrarily,can increase formaldehyde concentration.Therefore,in the room temperature,regulating air relative humidity in an appropriate level can improve the indoor air quality and decrease the harm of pollutants to human health.
