Analysis And Evaluation Of Building Indoor Air Quality

Having been demanded of conserving energy in the range of the world since 1970's,intensived leak proof of building , corresponding reduced new and amount of air condition .In the other hand, organism synthesis material was extensively applied equipment and instrument in the room, which rendered a lot of vapor organism compound gaseous sprayed ,so indoor air quality serious declined, coming vast symptom, termed "sick building syndrome" .Many countries in the world, for example, American, Japan, and so on, fairly valued indoor air quality, have researched very early, acquired definite achievement. In this direction, my country's research only underway, just belong to groping grade, relation indoor air quality's standard almost blank. A systematic study on many influence of indoor air quality and evaluation method of indoor air quality is made in this paper, which provide scientific warranty in or$er to improve indoor environment quality and establish standard of indoor environment quality.A systematic analysis on main pollution material and pollution source of building indoor is made in this paper, according to indoor pollution specialty, adopt K-E equal temperature model as mathematics model of rapidity current, adopt linear Newton_Raphson method, make research diffusion numeric simulation method about indoor pollution material. And it analyzed count method about ensuring indoor air quality's vapor environment building ventilation, which ventilation amount count is relevantly corrected, injecting essential change gas amount with Carbon dioxid.oxygen's standard. It analyzed presence question existing standard performanced process, introduced allowing exchange air amount count that ought to consider adverse material comprehensive influence. At analysis existing indoor air quality evaluation foundation, Imposing vague math's theory at first, which make vague comprehensive appraised about indoor air quality.
