中央空調(diào)空氣過濾器常識>>過濾器面積和過濾器壽命

過濾器阻力隨氣體流動的量和流速的增大而增加被捕捉或粘附的粉塵對氣流產(chǎn)生的阻力增大，使空氣過濾器的氣阻增大。

但另一方面，由于被捕捉粉塵與過濾介質(zhì)粘附為一體后，形成新的過濾屏障使過濾效率又略有改善。

但整體過濾效果決定于過濾面積的大小，能容納粉塵量的多少。故過濾器的使用壽命與過濾面積有關(guān)。在一般情況下，增大過濾器迎風(fēng)面積是延長過濾器過濾壽命的重要途徑。

Area and Life of Filters

The resistance of filters increases with augmented volume and velocity of air flow．Collected or adsorbed

dust and particles cause increasing resistance to airflow，which enlarges resistance of filters．Otherwise，

because of combined particle with filter media。that forming a new barrier of filter imProves the efficiency

slightly．But the total efficiency is up to area of filter and dust holding capacity．So the area has something

to do with life．In general，increasing area of filter plays a major role in prolonging life 0f filter．

有時(shí)，過濾器所捕捉的粉塵由于阻礙氣流的通過而產(chǎn)生反作用力，使粉塵飛揚(yáng)，稱為過濾器使用壽命終止的危險(xiǎn)信號。這時(shí)預(yù)示著整個(gè)過濾器報(bào)廢。

The more dust is collected on the filters，the larger resistance OCCUrs．The life of filter comes to the end

when resistance reaches a certain level．Sometimes，the dust collected by fiIter causes COUnterforce
