Results The Sanitary Indices of only two sets of air-conditioning systems were qualified according to the national sanitary standards, therefore, only 5 percent of the sanitary indices are op to the standard. And she qualifying rates of PM10, total bacteria count, total epiphyte count are 95.0%, 96.0% and 93.5% respectively. The detecting rate of Legionnaires pneumophile is 56% in 75 samples of cooling water. Hemolytic streptococcus can be found in one sample of the wind delivery and inner surface of blast pipe.
