前言空调系统冷却塔水中肺亲和性菌的生成和繁殖是当今国际制冷空调界关注的环境公害问题之一。这一问题的初次发现是在1976年7～8月间,那时美国费城饭店召开退伍军人大会,与会者中竟有233人突发原因不清的急性肺炎,其中29人死亡。经疾病控制中心查明致病病菌是肺亲和性菌,它是由于呼吸道感染所引起,经多方调研,确认其传播过程是起源于费城饭店大厦顶部的冷却塔冷却水受污染开始,冷却水中产生的肺亲和性菌
Introduction Air conditioning system cooling tower water lung affinity bacteria generation and reproduction is the current international refrigeration and air conditioning industry concerned about environmental pollution one of the problems. The initial discovery of this issue was between July and August 1976, when the Philadelphia Hospital of the United States held a meeting of veterans, and 233 of the participants unexpectedly caused acute pneumonia. Of these, 29 died. The disease control center identified by the Centers for Disease Control and Prevention virus is lung-compatible bacteria, which is caused due to respiratory tract infection, the multi-investigation, confirmed that the spread of the process is originated in the Philadelphia hotel tower cooling tower top cooling water began to contaminate the cooling water The resulting lung affinity bacteria
