為了使(shi)無塵(chen)室內(nei)保持所需要的(de)溫度(du)、濕度(du)、風速、壓力和潔凈(jing)度(du)等參數(shu)，常用的(de)方法是向室內(nei)不斷(duan)送(song)(song)(song)入(ru)一(yi)定量經過處理的(de)空(kong)氣(qi)，以消除無塵(chen)室內(nei)外各(ge)種(zhong)熱(re)濕干(gan)擾(rao)及塵(chen)埃污(wu)染，為獲得(de)送(song)(song)(song)入(ru)無塵(chen)室具有一(yi)定狀態的(de)空(kong)氣(qi)，就(jiu)需要一(yi)整(zheng)套(tao)設備(bei)對空(kong)氣(qi)進(jin)行處理，并(bing)不斷(duan)送(song)(song)(song)入(ru)室內(nei)，又(you)不斷(duan)從室內(nei)排(pai)出(chu)一(yi)部分(fen)來，這一(yi)整(zheng)套(tao)設備(bei)就(jiu)構成了凈(jing)化(hua)空(kong)調系(xi)統。

一(yi)、凈(jing)化空調(diao)系(xi)(xi)統的(de)基(ji)本(ben)構成凈(jing)化空調(diao)系(xi)(xi)統所用的(de)設備按(an)作用大致可分(fen)為三類:

1、加(jia)熱(re)或冷(leng)卻，加(jia)濕或去(qu)濕以及凈化設(she)備。2、將處(chu)理(li)后的空(kong)(kong)氣送入各(ge)無塵室(shi)并(bing)使之循環的空(kong)(kong)氣輸送設(she)備及其(qi)管(guan)路。3、向系(xi)統提(ti)供熱(re)量，冷(leng)量的熱(re)、冷(leng)源及其(qi)管(guan)路系(xi)統。 

二、凈化空調系(xi)統的(de)分類凈化空調系(xi)統一般分為三大類：

1、集(ji)中(zhong)(zhong)式(shi)凈(jing)(jing)化(hua)(hua)空(kong)(kong)調(diao)系統(tong)(tong)(tong)(tong)在(zai)(zai)系統(tong)(tong)(tong)(tong)內單個(ge)或(huo)多個(ge)潔凈(jing)(jing)室(shi)所需的凈(jing)(jing)化(hua)(hua)空(kong)(kong)調(diao)設(she)(she)備都(dou)集(ji)中(zhong)(zhong)在(zai)(zai)機房(fang)內，用送風管道(dao)將潔凈(jing)(jing)空(kong)(kong)氣配給各個(ge)無塵(chen)室(shi)。2、分(fen)散式(shi)凈(jing)(jing)化(hua)(hua)空(kong)(kong)調(diao)系統(tong)(tong)(tong)(tong)在(zai)(zai)系統(tong)(tong)(tong)(tong)內各個(ge)無塵(chen)室(shi)分(fen)別單獨設(she)(she)置(zhi)凈(jing)(jing)化(hua)(hua)設(she)(she)備或(huo)凈(jing)(jing)化(hua)(hua)空(kong)(kong)調(diao)設(she)(she)備。3、半集(ji)中(zhong)(zhong)式(shi)凈(jing)(jing)化(hua)(hua)空(kong)(kong)調(diao)系統(tong)(tong)(tong)(tong)在(zai)(zai)這(zhe)種(zhong)(zhong)系統(tong)(tong)(tong)(tong)中(zhong)(zhong)，即有(you)集(ji)中(zhong)(zhong)的凈(jing)(jing)化(hua)(hua)空(kong)(kong)調(diao)機房(fang)，又有(you)分(fen)散在(zai)(zai)各無塵(chen)室(shi)內的空(kong)(kong)氣處(chu)理(li)設(she)(she)備，是一種(zhong)(zhong)集(ji)中(zhong)(zhong)處(chu)理(li)和局部(bu)處(chu)理(li)相(xiang)結合的形式(shi)。 

人(ren)們一(yi)般按(an)系(xi)(xi)統(tong)內各無塵(chen)室的潔凈(jing)(jing)(jing)度來命名(ming)系(xi)(xi)統(tong)，如稱之為(wei)100級凈(jing)(jing)(jing)化(hua)(hua)(hua)(hua)空(kong)調系(xi)(xi)統(tong)，1000級凈(jing)(jing)(jing)化(hua)(hua)(hua)(hua)空(kong)調系(xi)(xi)統(tong)等。有時也按(an)系(xi)(xi)統(tong)的末級過濾器的性質來區(qu)分，分為(wei)高效空(kong)氣(qi)凈(jing)(jing)(jing)化(hua)(hua)(hua)(hua)系(xi)(xi)統(tong)，亞高效空(kong)氣(qi)凈(jing)(jing)(jing)化(hua)(hua)(hua)(hua)系(xi)(xi)統(tong)和中效空(kong)氣(qi)凈(jing)(jing)(jing)化(hua)(hua)(hua)(hua)系(xi)(xi)統(tong)。

三、凈化空調(diao)系統消(xiao)毒(du)方法注意(yi)：消(xiao)毒(du)前(qian)確(que)認潔凈區內所有人員(yuan)已經(jing)撤出，生產(chan)處于停止狀態。

1.臭氧(yang)消毒

消毒(du)方(fang)式為(wei)臭(chou)(chou)氧(yang)發生器(qi)產生一定濃度臭(chou)(chou)氧(yang)，由風機(ji)風管帶入潔凈區內進行(xing)消毒(du)。臭(chou)(chou)氧(yang)消毒(du)一般在無人情(qing)況下進行(xing)，目前我國藥(yao)廠都是沿用(yong)臭(chou)(chou)氧(yang)對空調通風系(xi)統(tong)進行(xing)消毒(du)。公共場(chang)所為(wei)人群聚集的(de)(de)場(chang)所，一般不選用(yong)單獨的(de)(de)臭(chou)(chou)氧(yang)消毒(du)方(fang)法。 

2.紫(zi)外(wai)(wai)線消毒紫(zi)外(wai)(wai)線照射對靜止的物體或空氣消毒具有十分可靠的效果, 但紫(zi)外(wai)(wai)線穿透性較(jiao)差(cha), 遮擋(dang)角(jiao)落(luo)不易被消毒; 且紫(zi)外(wai)(wai)線沒(mei)有除(chu)塵作用(yong)，空氣中的塵埃粒子可能會影響其消毒效果。
