購入了家用新風(fēng)系統(tǒng)，怎么判斷效果如何？

2020-08-04 59424

　　判斷家用新風(fēng)去除PM2.5的效果，一方面我們需要借助PM2.5檢測儀。需要注意的是，不要盲目追求“出風(fēng)口為零”，這不是我們真正需要的作用;也不要只檢查新風(fēng)系統(tǒng)出風(fēng)口PM2.5值，出風(fēng)口PM2.5值低不代表室內(nèi)PM2.5值降低得很快。

　　另一方面，我們要看新風(fēng)系統(tǒng)的風(fēng)量。為了快速降低室內(nèi)PM2.5值，新風(fēng)系統(tǒng)需要具有足夠的風(fēng)量，并且，帶有內(nèi)循環(huán)功能的新風(fēng)系統(tǒng)更容易實(shí)現(xiàn)這一點(diǎn)。

　　建議用PM2.5檢測儀來檢測新風(fēng)系統(tǒng)出風(fēng)口PM2.5值，然后檢測室內(nèi)值，再把獲得的數(shù)值與室外PM2.5值比較。這樣您才能夠判斷新風(fēng)系統(tǒng)的防霾效果。

　　判斷家用新風(fēng)系統(tǒng)通風(fēng)效果

　　通風(fēng)換氣才是新風(fēng)系統(tǒng)的真正作用。判斷家用新風(fēng)系統(tǒng)通風(fēng)換氣效果的標(biāo)準(zhǔn)，不是出風(fēng)速度，更重要的是新風(fēng)量(不是風(fēng)量!有些機(jī)器的風(fēng)量值很大部分是室內(nèi)循環(huán)風(fēng))。新風(fēng)系統(tǒng)每小時(shí)送入多少新鮮空氣，才是決定通風(fēng)換氣效果最重要的因素。

　　另外，家用新風(fēng)通風(fēng)效果的衡量依據(jù)不是室內(nèi)PM2.5值，而是室內(nèi)二氧化碳濃度。如果你能檢測室內(nèi)二氧化碳濃度，你會發(fā)現(xiàn)在密閉的室內(nèi)睡了8個(gè)小時(shí)之后，屋里二氧化碳濃度已達(dá)到不健康的數(shù)值。開啟新風(fēng)機(jī)之后，你關(guān)注室內(nèi)二氧化碳濃度，如果可以一直保持在1000 PPM之內(nèi)，那么通風(fēng)效果就很好。

　　判斷家用新風(fēng)系統(tǒng)除甲醛效果

　　家用新風(fēng)系統(tǒng)祛除甲醛的原理并不是“過濾”，不是通過機(jī)器內(nèi)置過濾甲醛的裝置，而是通過通風(fēng)換氣方式將室內(nèi)污染空氣代替成潔凈的外界新鮮空氣。也就是說，室內(nèi)甲醛并不會經(jīng)過新風(fēng)系統(tǒng)的濾網(wǎng)，而是經(jīng)過新風(fēng)系統(tǒng)的通風(fēng)換氣的作用從室內(nèi)擠壓出去，往室外排走。

　　因此，新風(fēng)系統(tǒng)除甲醛效果完全取決于它的新風(fēng)量。新風(fēng)量足夠，除甲醛的效果就自然而然會很好。

　　判斷家用新風(fēng)系統(tǒng)除異味效果

　　與二氧化碳和甲醛一樣，家用新風(fēng)系統(tǒng)除異味也是通過不斷通風(fēng)換氣將室內(nèi)異味排出去。但新風(fēng)系統(tǒng)必須要從送入室內(nèi)的空氣中去除有害氣體和異味。如果新風(fēng)系統(tǒng)沒有處理有害氣體的技術(shù)或裝置，則它雖然能高效過濾PM2.5，但完全過濾不了有害氣體、化工異味和汽車尾氣。所以，我們在選購新風(fēng)系統(tǒng)時(shí)要關(guān)注一下它是否標(biāo)配活性炭濾網(wǎng)。活性炭濾網(wǎng)也不能太小，否則它很快就失效!

　　判斷家用新風(fēng)系統(tǒng)消音效果

　　家用新風(fēng)系統(tǒng)噪音是最容易被消費(fèi)者忽略的指數(shù)，而且是最影響用戶體驗(yàn)的元素。因此，在選購家用新風(fēng)的時(shí)候一定要非常重視噪音指數(shù)。看看詳情頁上的噪音分貝數(shù)，如果信息不夠齊全，再向賣家咨詢具體數(shù)據(jù)。網(wǎng)上也有相關(guān)指南可以讓你更容易理解新風(fēng)系統(tǒng)噪音分貝數(shù)的含義。
