　　2.物理清洗的優點

可以省去(qu)化學清(qing)洗所(suo)需的藥劑(ji)費用(yong)；避免(mian)了化學清(qing)洗后清(qing)洗廢液的處理和排放問(wen)題；不易引起被清(qing)洗設備的腐(fu)蝕(shi)。

　　(二)化學清洗

化(hua)(hua)學(xue)清(qing)洗(xi)是通過化(hua)(hua)學(xue)藥(yao)劑的(de)作用,使被(bei)清(qing)洗(xi)設備中的(de)沉(chen)積物溶解、疏松(song)、脫落或剝離(li)的(de)一(yi)類(lei)方(fang)法。化(hua)(hua)學(xue)清(qing)洗(xi)也(ye)常和(he)物理清(qing)洗(xi)配合使用。

　　1.化學清洗分類

　　(1)按清洗(xi)方式分,中央空調水系統(tong)的(de)化學清洗(xi)可(ke)分為(wei)循環法和浸泡法清洗(xi)。

循環(huan)(huan)法是一(yi)種使用較為廣泛的(de)方(fang)法。利用臨時(shi)清洗(xi)(xi)槽等(deng)方(fang)法,使清洗(xi)(xi)設(she)備形成一(yi)個(ge)閉合回路(lu),清洗(xi)(xi)液不斷循環(huan)(huan), 沉(chen)積層等(deng)不斷受到新鮮清洗(xi)(xi)液的(de)化(hua)學作用和(he)沖刷作用而(er)溶解和(he)脫落。浸泡法適(shi)用于一(yi)些小型設(she)備和(he)被沉(chen)積物(wu)堵死而(er)無法將清洗(xi)(xi)液進行循環(huan)(huan)的(de)設(she)備。

　　(2)按使用的清洗(xi)劑分(fen),中央(yang)空調水(shui)系(xi)統的化學清洗(xi)可分(fen)為堿洗(xi)、酸洗(xi)、殺菌滅藻清洗(xi)等。

　　(3)按清(qing)洗的(de)對象分(fen),中央空調水系統(tong)的(de)化學清(qing)洗可(ke)分(fen)為單臺設備(bei)清(qing)洗和全(quan)系統(tong)清(qing)洗。

　　(4)按是(shi)否(fou)停(ting)機分,中央空(kong)調(diao)水系(xi)統的化(hua)學清洗可分為停(ting)機清洗和不停(ting)機清洗。

不停機(ji)(ji)清(qing)(qing)洗(xi)指的是清(qing)(qing)洗(xi)液循環過(guo)程中,制(zhi)冷(leng)(leng)機(ji)(ji)組仍處于開機(ji)(ji)狀態(tai),清(qing)(qing)洗(xi)液作為冷(leng)(leng)卻水(shui)或冷(leng)(leng)凍水(shui),在(zai)空(kong)調(diao)系(xi)統(tong)內(nei)部(bu)管線中循環。

　　2.化學清洗的優點

沉積物等能夠被清除(chu),清洗效果(guo)好；可以(yi)進(jin)行不停機清洗,以(yi)保(bao)證制冷(或(huo)供熱)的(de)照常進(jin)行；清洗操(cao)作比較簡單(dan)。

　　如上(shang)是(shi)濰坊(fang)美(mei)的中(zhong)央空(kong)調機組循(xun)環水系統(tong)清洗方法的詳細介(jie)紹，給(gei)大家講解(jie)了具體(ti)該如何清洗，大家可以參考如上(shang)步驟去進行中(zhong)央空(kong)調機組循(xun)環水系統(tong)的清洗。
