INDOOR AIR QUALITY ON BASIS OF NATURE
VENTIATLION AND NATURE VENTILATION
MULTIPLICITY RESEARECH
Abstract
The real health effects of air pollution depend on the concentrations
experienced by people rather than those recorded by stationary air quality
monitors located outdoors for people spend 70~90% of their time in indoor. But
indoor air quality in one zone depend on outdoor air quality, the air quality of
neighbor zone and indoor pollutant source. The relationships of the pollutant
concentration of indoor and outdoor, linking zone were researched and
analysed. A model on the basis of nature ventilation MIX model was developed
to predict long-term indoor air pollutant concentration, and the model was used
to analyse individual exposure in different micro-environment. The relationship
of temperature and ventilation was researched when considered heat source
effect. And a dynamic model was developed to predict indoor air pollutant
concentration and indoor temperature. The airflow of nature ventilation, a
non-linear system, plexity and exist multi solutions, which is sensitive to
the initial value. A two-zone building was researched in this paper and it is
found that there will be two stable points and hopf bifurcation in some
conditions even if there is only a two-zone building model. The whole
bifurcation drawings of two-zone building were also drawn in this paper.
