THE ANALYSIS OF FACTORS OF EFFECTING CONCENTRATION IN THE VENTILATING ROOM

摘要

There are many factors that effect the concentration in the room, such as flow rate, efficiency ofrnfilter, source, etc. Based on the work before, the paper gets the steady concentration in the ventilatingrnroom and reexplains some phenomena that are understood incorrectly. In order to decreasing thernconcentration in the room, the paper analyses the factors quantificationally. Facing the different practicalrnventilation system, how to configure the whole system to attain sanitation standard and the request ofrnhealth under the minimum fresh air rate, the paper puts forward the corresponding solvents under therndifferent situation.
