The condition of the air inside buildings, including the extent of pollution caused by smoking, dust, mites, mold spores, radon, and gases and chemicals from materials and appliances.
Cognizance about Importance of indoor air quality .
We spend about 90% of our time indoors in our homes, cars, offices, factories, public buildings such as restaurants, malls, and others.
Dilution rates of atmospheric pollution
Dilution rates of indoor air pollution
Without proper ventilation, increase concentration
Negative influence on human
Factors on Influencing indoor air quality(application box model)
(A), exchange (B), indoor concentration
(C), outgassing of building and furniture materials
(D), infiltration from soils (E), removal on interior surfaces
IN - OUT + SOURCE
Optional Value Substitution !
Suppose : f(t)=C
(V) is not related to (C)
, but inverse proportion with Diffusion Velocity
Q ∝ C
C ∝ C
Increase amount of ventilation(Q)
Decrease pollution Concentration
