Abstract—in this paper the change law of concentration of indoor
PM10 in the air-conditioning room is studied. By using the law of II. FORMULA DERIVATIONS
conservation of mass and calculus formulas, the functional
relation between concentration of indoor PM10 and time is monly used air conditioning system can be divided
derived from three different air-conditioning systems which into dedicated outdoor air system and system dealing with

Through the practical measurement of an office building, the respectively in this paper.
