OPTIMIZATION OF THE POSITIONS OF INDOOR CONTAMINANT SOURCES AND SINKS BY USING A NEW CONCEPTION-SPATIAL FLOW INFLUENCE FACTOR

A new concept, the spatial flow influence factor (SFIF), put forward by us in our previous paper, provides a new insight into the airflow structure. In this paper, several typical illustrative examples are presented to show: (1) how to optimally arrange the chemical pollutant sources and the occupied regions for a given indoor airflow; (2) how to optimize the position of adsorption materials. From the examples, it is seen that the concept is powerful in the control of indoor air gas pollutants.
