風(fēng)管系統(tǒng)是一個(gè)住所的呼吸系統(tǒng)。當(dāng)風(fēng)管變臟或堵塞時(shí)，就應(yīng)該清洗，這樣才能讓風(fēng)管呼吸順暢和高效。當(dāng)空調(diào)打開時(shí)，污染物就會(huì)被排出并在屋中循環(huán)，并危及到居民的健康。開空調(diào)時(shí)，如果有人感覺到發(fā)霉的或污濁的氣味或早晚感覺到頭疼、鼻塞或其他不舒服，這說(shuō)明空調(diào)的風(fēng)管該清洗了。Airductsystemistherespiratorysystemofyourhome.Whenitbecomescontaminatedandcongested,itshouldbecleanedsoitcan"breathe"normallyandefficiently.Whenairconditioneristurnedon,contaminantsarespewedoutandcirculatedthroughoutyourhomeandaffectthehealthandcomfortofresidents.Anyonemayfeel"musty"or"stale"odorsorsufferfromheadaches,nasalcongestion,orothertroubleproblemsatnightorinthemorningwhenairconditionerruns,whichshowductofairconditionerneedbecleaned.1

顯然，風(fēng)管清洗有助于室內(nèi)干凈和健康受益。還有助于恢復(fù)供暖空調(diào)系統(tǒng)的能力，運(yùn)行時(shí)間縮短，供暖和制冷費(fèi)用降低。如果決定給空調(diào)系統(tǒng)做清潔，重要的是要確保系統(tǒng)的所有部件都清潔徹底并保質(zhì)保量。風(fēng)管清潔包括送風(fēng)管和回風(fēng)管、通風(fēng)調(diào)節(jié)設(shè)備、格柵口、擴(kuò)散器、熱交換器、冷凝水積水盤、風(fēng)機(jī)馬達(dá)和空氣處理器等。Obvious,ductcleaningcanhelpmaintainacleanerhomeandthesufficienthealthbenefits.ItalsohelpstorestoreHVACsystemcapacityandlessenrunningtime,resultinginlowerheatingandcoolingcost.Ifyoudecidetohaveyourheatingandcoolingsystemcleaned,itisimportanttomakesuretocleanallcomponentsofthesystemandisqualifiedtodoso.2Ductcleaninggenerallyincludethesupplyandreturnairductsandregisters,grillesanddiffusers,heatexchangersheatingandcoolingcoils,condensatedrainpans,fanmotor,andtheairhandlingunithousing,etc.Text

雖然工業(yè)協(xié)會(huì)對(duì)風(fēng)管清洗有相關(guān)標(biāo)準(zhǔn)，但是方法還是有很多種的。傳統(tǒng)的方法都是服務(wù)人員使用專門的工具去除灰塵和雜物，然后再用高能真空吸塵器吹掃。另外，有一些服務(wù)人員還建議使用化學(xué)處理方法（密封膠或膠性密封劑）密封或涂抹風(fēng)管內(nèi)表面和設(shè)備外殼，因?yàn)樗麄冋J(rèn)為這樣能控制微生物生長(zhǎng)并阻止灰塵微粒和纖維等進(jìn)入風(fēng)管。Methodsofductcleaningvary,althoughstandardshavebeenestablishedbyindustryassociationsconcernedwithairductcleaning.Typically,aserviceproviderwillusespecializedtoolstodislodgedirtandotherdebrisinducts,thenvacuumthemoutwithahigh-poweredvacuum

驗(yàn)證空調(diào)系統(tǒng)清潔潔凈度的最好方法是嚴(yán)格的視覺檢查。有的服務(wù)人員會(huì)用遠(yuǎn)程拍攝來(lái)記錄分管內(nèi)部清洗前后的情況。系統(tǒng)所有的部分都要做可視檢查。另外，風(fēng)管中不能潮濕。如果存在潮濕，潛在的微生物（比如霉菌）就會(huì)迅速滋生，并進(jìn)入到房間區(qū)域?？刂瞥睗袷欠乐癸L(fēng)管中微生物生長(zhǎng)的最有效的方法。Athoroughvisualinspectionisthebestwaytoverifythecleanlinessofyourheatingandcoolingsystem.Someserviceprovidersuseremotephotographytodocumentconditionsinsideductscleanedbeforeandlater.Allportionsofthesystemshouldbevisiblyclean.4

潮濕會(huì)經(jīng)過(guò)漏洞或系統(tǒng)安裝和維護(hù)不合適進(jìn)入風(fēng)管系統(tǒng)。研究表明，空調(diào)的冷凝水是系統(tǒng)潮濕污染的一個(gè)主要來(lái)源（當(dāng)表面溫度低于環(huán)境空氣的露點(diǎn)溫度時(shí)）。冷凝水和相對(duì)濕度大都是促進(jìn)風(fēng)管中霉菌生長(zhǎng)的重要因素。Moisturecanentertheductsystemthroughleaksorifthesystemhasbeenimproperlyinstalledorserviced.Researchsuggeststhatcondensation(whichoccurswhenasurfacetemperatureislowerthanthedewpointtemperatureofthesurroundingair)onornearcoolingcoilsofairconditioningunitsisamajorfactorinmoisturecontaminationofthesystem.Thepresenceofcondensationorhighrelative
