有幾個(gè)因素可以決定你需要什么樣的凈化車(chē)間環(huán)境。每個(gè)行業(yè)都有自己的規(guī)格要求。主要問(wèn)題是保證空氣中存在什么類(lèi)型的粒子?

　　There are several factors that can determine what kind of cleanup workshop environment you need. Each industry has its own specifications. The main question is to ensure what type of particles exist in the air.

　　車(chē)間要求是封閉的空間，幾乎沒(méi)有污染物。灰塵、細(xì)菌或病毒可以減少某些類(lèi)型的實(shí)驗(yàn)室工作。

　　Workshop requirements are closed space, almost no pollutants. Dust, bacteria or viruses can reduce certain types of laboratory work.

　　ISO 14644標(biāo)準(zhǔn)描述潔凈室的空氣質(zhì)量。較舊的參考資料是“聯(lián)邦標(biāo)準(zhǔn)209清潔房間和清潔區(qū)域內(nèi)的微粒清潔度等級(jí)”

　　The ISO 14644 standard describes the empty quality of the clean room. The older reference is the Federal Standard 209 for cleaning rooms and cleaning areas for particulate cleanliness.

　　每立方米不超過(guò)352,000粒0.5微米或更多的微粒。另一個(gè)標(biāo)準(zhǔn)是每小時(shí)換空氣的次數(shù)。潔凈室以每小時(shí)60至750次的速度交換空氣以過(guò)濾外部空氣。

　　No more than 352000 microns or more particles per cubic meter. Another standard is the number of air changes per hour. The clean room exchanges air at a speed of 60 to 750 times an hour to filter the external air.

　　總之各行業(yè)要打造符合行業(yè)標(biāo)準(zhǔn)的凈化車(chē)間。比如計(jì)算機(jī)芯片制造商可能需要更干凈的過(guò)濾。一個(gè)門(mén)窗廠家就可能不太需要干凈的環(huán)境了。
