隨著我(wo)國中(zhong)(zhong)(zhong)國養空(kong)調(diao)的(de)快速(su)發展(zhan)，中(zhong)(zhong)(zhong)央空(kong)調(diao)給我(wo)們的(de)生活舒適(shi)的(de)同時(shi)(shi)，也給我(wo)們帶來衛生隱患。雜亂的(de)空(kong)調(diao)清洗(xi)市場，空(kong)調(diao)清洗(xi)質(zhi)量難以保證，且時(shi)(shi)有欺(qi)詐(zha)行(xing)(xing)為(wei)。規范中(zhong)(zhong)(zhong)央空(kong)調(diao)清洗(xi)行(xing)(xing)業成為(wei)刻不容緩的(de)問(wen)題。
制冷設備化學清洗技術發展趨勢
鑒于酸(suan)洗技(ji)術(shu)(shu)對中(zhong)央空(kong)(kong)(kong)(kong)調(diao)設備的(de)(de)強腐蝕性(xing)和(he)對生(sheng)態環境(jing)的(de)(de)高污(wu)(wu)染(ran)(ran)性(xing)，目前國內(nei)(nei)外都(dou)在積(ji)極研(yan)究開(kai)發(fa)安全(quan)、無污(wu)(wu)染(ran)(ran)的(de)(de)清(qing)洗技(ji)術(shu)(shu)。由于水處理(li)和(he)化學清(qing)洗對中(zhong)央空(kong)(kong)(kong)(kong)調(diao)系統的(de)(de)安全(quan)、正常運行影響(xiang)很大(da)，近年(nian)來酸(suan)洗不當造成價值千萬元的(de)(de)中(zhong)央空(kong)(kong)(kong)(kong)調(diao)系統嚴重腐蝕甚至報廢的(de)(de)酸(suan)洗事故時有發(fa)生(sheng)。因此(ci)，國內(nei)(nei)部(bu)分(fen)(fen)省區的(de)(de)技(ji)術(shu)(shu)監管機構(gou)已開(kai)始對中(zhong)央空(kong)(kong)(kong)(kong)調(diao)清(qing)洗實行嚴格(ge)的(de)(de)清(qing)洗安全(quan)監管。國家環保局(ju)也把酸(suan)洗技(ji)術(shu)(shu)列為九(jiu)大(da)污(wu)(wu)染(ran)(ran)源頭之一，將進行限制和(he)治(zhi)理(li)。國內(nei)(nei)部(bu)分(fen)(fen)地(di)區已嚴格(ge)禁止(zhi)酸(suan)洗中(zhong)央空(kong)(kong)(kong)(kong)調(diao)和(he)其它熱交換設備。
隨著(zhu)國家環保立法和執(zhi)法力度的(de)加大(da)，用(yong)(yong)高效、安全、無(wu)污染的(de)化(hua)學清洗(xi)(xi)技(ji)術替代目前使用(yong)(yong)的(de)酸洗(xi)(xi)技(ji)術，必(bi)(bi)將成(cheng)為中央(yang)空(kong)調清洗(xi)(xi)技(ji)術發展(zhan)的(de)必(bi)(bi)然(ran)趨(qu)勢。中性(xing)無(wu)酸清洗(xi)(xi)技(ji)術成(cheng)功(gong)地應用(yong)(yong)于中央(yang)空(kong)調清洗(xi)(xi)領域，無(wu)疑是一條二十(shi)一世紀中央(yang)空(kong)調化(hua)學清洗(xi)(xi)和水處理技(ji)術發展(zhan)的(de)必(bi)(bi)由之(zhi)路。
《空調通風系統清洗規范》強制性的國家標準
我國目前(qian)有超(chao)過(guo)500萬個中(zhong)央空調系統(tong)亟待清洗(xi)保(bao)養，一些中(zhong)央空調運行了(le)20年(nian)，卻從(cong)未清洗(xi)過(guo)。空調系統(tong)在(zai)長(chang)期運行的過(guo)程中(zhong)，很容易出現(xian)灰塵(chen)(chen)沉積與阻塞(sai)，造成微生物滋(zi)生、風(feng)力受阻、機組能力下降(jiang)和(he)(he)壓縮機功耗增加等問(wen)題。解(jie)決這些問(wen)題最根本的方法，就是對(dui)空調通風(feng)系統(tong)進行徹底的清洗(xi)。但(dan)是，如果清洗(xi)中(zhong)不按照(zhao)規范的技(ji)術要求操作，通風(feng)管道中(zhong)的灰塵(chen)(chen)、細菌和(he)(he)微生物等將對(dui)周圍的環境、清洗(xi)人員、空調用戶和(he)(he)空調設備帶來極大的危害。
跟國(guo)(guo)外相(xiang)比，原來(lai)中(zhong)(zhong)(zhong)國(guo)(guo)制(zhi)冷設備的(de)(de)相(xiang)關標(biao)準(zhun)(zhun)比較低。首先表現在對(dui)(dui)中(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)調(diao)(diao)新風(feng)(feng)量要(yao)求(qiu)的(de)(de)差(cha)距上。世界(jie)發(fa)達(da)國(guo)(guo)家對(dui)(dui)中(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)調(diao)(diao)新風(feng)(feng)量要(yao)求(qiu)一(yi)(yi)般(ban)(ban)是(shi)30-50立方(fang)(fang)米／小時(shi)(shi)，新風(feng)(feng)量達(da)不(bu)(bu)到(dao)(dao)標(biao)準(zhun)(zhun)就不(bu)(bu)準(zhun)(zhun)運行(xing)。目前，我國(guo)(guo)對(dui)(dui)中(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)調(diao)(diao)新風(feng)(feng)量的(de)(de)要(yao)求(qiu)一(yi)(yi)般(ban)(ban)只有(you)20立方(fang)(fang)米／小時(shi)(shi)，有(you)的(de)(de)甚至(zhi)更低，不(bu)(bu)少(shao)新風(feng)(feng)量很(hen)低的(de)(de)中(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)調(diao)(diao)一(yi)(yi)直在銷售使用；其(qi)次，國(guo)(guo)外對(dui)(dui)中(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)調(diao)(diao)空(kong)(kong)(kong)氣(qi)(qi)過濾的(de)(de)要(yao)求(qiu)較高(gao)，如(ru)日本強(qiang)制(zhi)性(xing)要(yao)求(qiu)中(zhong)(zhong)(zhong)效過濾，達(da)不(bu)(bu)到(dao)(dao)將受到(dao)(dao)嚴厲懲(cheng)罰。我國(guo)(guo)對(dui)(dui)中(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)調(diao)(diao)只使用簡單過濾網，不(bu)(bu)少(shao)中(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)調(diao)(diao)連低效過濾都達(da)不(bu)(bu)到(dao)(dao)，也(ye)沒(mei)有(you)什么(me)懲(cheng)罰措施；第三，國(guo)(guo)外對(dui)(dui)中(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)調(diao)(diao)排風(feng)(feng)要(yao)求(qiu)很(hen)高(gao)，并且是(shi)強(qiang)制(zhi)性(xing)的(de)(de)，國(guo)(guo)內(nei)(nei)一(yi)(yi)般(ban)(ban)沒(mei)有(you)此項要(yao)求(qiu)；最后(hou)，國(guo)(guo)外中(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)調(diao)(diao)普遍裝(zhuang)(zhuang)有(you)空(kong)(kong)(kong)氣(qi)(qi)加(jia)濕裝(zhuang)(zhuang)置(zhi)(zhi)，國(guo)(guo)內(nei)(nei)中(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)調(diao)(diao)很(hen)少(shao)見(jian)到(dao)(dao)空(kong)(kong)(kong)氣(qi)(qi)加(jia)濕裝(zhuang)(zhuang)置(zhi)(zhi)，也(ye)很(hen)少(shao)有(you)企業主動安裝(zhuang)(zhuang)空(kong)(kong)(kong)氣(qi)(qi)加(jia)濕裝(zhuang)(zhuang)置(zhi)(zhi)。國(guo)(guo)外對(dui)(dui)中(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)調(diao)(diao)風(feng)(feng)管潔凈度要(yao)求(qiu)嚴格(ge)，在施工(gong)質(zhi)量、管理、檢查、經常性(xing)清洗等(deng)方(fang)(fang)面(mian)一(yi)(yi)直保持著標(biao)準(zhun)(zhun)很(hen)高(gao)的(de)(de)評(ping)判指標(biao)，原來(lai)國(guo)(guo)內(nei)(nei)在這(zhe)方(fang)(fang)面(mian)好象沒(mei)什么(me)要(yao)求(qiu)。國(guo)(guo)外中(zhong)(zhong)(zhong)央(yang)(yang)空(kong)(kong)(kong)調(diao)(diao)的(de)(de)制(zhi)造(zao)標(biao)準(zhun)(zhun)體現出(chu)很(hen)高(gao)的(de)(de)環保特性(xing)、智(zhi)能化、網絡化特性(xing)，對(dui)(dui)生產(chan)過程、材(cai)料、制(zhi)冷劑等(deng)都有(you)較高(gao)的(de)(de)環保要(yao)求(qiu)，更強(qiang)調(diao)(diao)空(kong)(kong)(kong)氣(qi)(qi)品(pin)質(zhi)。
《空(kong)調通(tong)(tong)風系(xi)統(tong)清洗規(gui)范》明(ming)確規(gui)定了(le)那些通(tong)(tong)風系(xi)統(tong)被污染、通(tong)(tong)風系(xi)統(tong)性能下降和對(dui)室內環境有特殊要(yao)求的中央空(kong)調系(xi)統(tong)需(xu)要(yao)清洗。
《空(kong)調通(tong)風系統(tong)(tong)清(qing)洗(xi)規范》明確了對(dui)中(zhong)央空(kong)調的清(qing)洗(xi)方(fang)法(fa)(fa)，主(zhu)要(yao)(yao)(yao)是(shi)通(tong)過各種機械設備或工具(ju)，通(tong)過物(wu)理方(fang)式將(jiang)通(tong)風系統(tong)(tong)中(zhong)的污染物(wu)從通(tong)風系統(tong)(tong)部件表面剝(bo)離(li)下來。清(qing)洗(xi)過程(cheng)中(zhong)使(shi)用(yong)的化(hua)學制(zhi)劑，應(ying)滿足國家有(you)關法(fa)(fa)律法(fa)(fa)規和相關標準的要(yao)(yao)(yao)求，不應(ying)對(dui)通(tong)風系統(tong)(tong)和人員造成(cheng)損害。清(qing)洗(xi)公司(si)和用(yong)戶需要(yao)(yao)(yao)特別注意的是(shi)，污染物(wu)被剝(bo)離(li)下來后，必須(xu)進行安全(quan)封裝(zhuang)，并按國家相關規定(ding)進行處理。
中(zhong)央(yang)空調清洗對提高(gao)我國人(ren)民(min)的(de)生活質(zhi)量有著(zhu)不(bu)可忽(hu)視的(de)重要作用，規范空調清洗市場意義深遠。
