3.確定集中(zhong)或分散式(shi)凈(jing)(jing)化(hua)空氣調節(jie)系統時(shi)，應綜合考慮(lv)生(sheng)產(chan)工藝的(de)特(te)點和凈(jing)(jing)化(hua)車間(jian)空氣的(de)潔凈(jing)(jing)度等級、面積、位置(zhi)等因(yin)素(su)。凡(fan)生(sheng)產(chan)工藝連續、無塵室(shi)或凈(jing)(jing)化(hua)車間(jian)面積較大時(shi)，位置(zhi)集中(zhong)以及噪聲控(kong)制(zhi)(zhi)和振(zhen)動(dong)控(kong)制(zhi)(zhi)要求嚴格的(de)潔凈(jing)(jing)室(shi)，宜采用集中(zhong)式(shi)凈(jing)(jing)化(hua)空氣調節(jie)系統。

4.凈(jing)化空氣(qi)調節系統(tong)如需(xu)電(dian)加熱(re)時，應(ying)選用管狀(zhuang)電(dian)加熱(re)器(qi)，位置應(ying)布置在高效(xiao)空氣(qi)過濾(lv)器(qi)的上風側，并應(ying)有防火安全措施。

5.凈化(hua)工程中(zhong)凈化(hua)空氣調節(jie)系統(tong)(tong)除直(zhi)流(liu)式系統(tong)(tong)和設置值(zhi)班風機的系統(tong)(tong)外，應采(cai)取(qu)防(fang)止室外污染空氣通過新風口(kou)參入凈化(hua)車間內的防(fang)灌倒措施。

6.凈(jing)化空氣(qi)調節系(xi)統設計應合理利用(yong)回風，凡工(gong)藝過程產生大量有害(hai)物質且(qie)局部處理不能滿足衛生要求(qiu)，或對其(qi)他工(gong)序(xu)有危害(hai)時，則不應用(yong)回風。
