Chiyambireni kupangidwa kwake, oyeretsa mpweya wapakhomo asintha mawonekedwe ndi kuchuluka kwake, kusinthika kwaukadaulo wazosefera, komanso kupanga miyezo yokhazikika, ndipo pang'onopang'ono amakhala njira yothetsera mpweya wamkati yomwe imatha kulowa m'nyumba iliyonse ndikupanga ogula kuti agulitse.Pamodzi ndi masinthidwe awa, ukadaulo wazosefera wapitilira kusintha.Pakadali pano, matekinoloje ofunikira kwambiri oyeretsa mpweya ndikugwiritsa ntchito zosefera za HEPA, ma ion, ndi photocatalysis.
Koma si mankhwala onse oyeretsa mpweya amene amayeretsa mpweya bwinobwino.
Chifukwa chake, ogula akagula zoyeretsa mpweya, ndikofunikira kumvetsetsa bwino zomwe zimayeretsa mpweya wabwino.
1. KODI AZOSEFA HEPA?
HEPA monga fyuluta ya air-effective particulate air (HEPA) imagwiritsa ntchito ulusi wandiweyani, wosanjidwa mwachisawawa kuti igwire tinthu tating'onoting'ono tochokera mumlengalenga.Zosefera za HEPA zimagwiritsa ntchito fiziki ya tinthu tating'onoting'ono tomwe timayenda mumlengalenga kuti tituluke mumayendedwe a mpweya.Kuchita kwawo ndikosavuta koma kothandiza kwambiri, ndipo zosefera za HEPA tsopano ndizokhazikika pafupifupi pafupifupi zoyeretsa mpweya uliwonse pamsika.
Koma sizili choncho nthawi zonse.
Kuyambira m'zaka za m'ma 1940, bungwe la US Atomic Energy Commission linayamba kuyesa njira zogwiritsira ntchito tinthu tating'ono kuti titeteze asilikali ku cheza cha atomiki pa nkhondo yachiwiri ya padziko lonse.Njira yojambulira tinthu yogwira bwino kwambiri imeneyi yakhalanso chitsanzo chachikulu cha HEPA chomwe chimagwiritsidwa ntchito poyeretsa mpweya.
Zosefera za HEPA sizimasefa ma radiation, ofufuza adazindikira mwachangu kuti zosefera za HEPA zimatha kusefa zinthu zambiri zowononga.
US Department of Energy (DOE) imafuna kuti zosefera zonse zogulitsidwa pansi pa dzina la "HEPA" zisefe osachepera 99.97% ya tinthu tating'onoting'ono towuluka ndi ma microns 0.3.
Kuyambira pamenepo, HEPA kuyeretsa mpweya wakhala muyezo mu makampani kuyeretsa mpweya.HEPA tsopano ndi yotchuka ngati mawu achibadwa pa zosefera za mpweya, koma zosefera za HEPA zimapitilira kusefa 99.97% ya tinthu tating'ono mpaka ma microns 0.3.
2. SI ONSE OYERETSA AIR ANAPANGIDWA ZOMWEZI
Onse opanga zoyeretsa mpweya amadziwa kuti zosefera zawo ziyenera kukwaniritsa muyezo wa HEPA uwu.Koma si mitundu yonse ya makina oyeretsera mpweya omwe amagwira ntchito.
Kuti mulengeze choyeretsa mpweya ngati HEPA, chimangofunika kukhala ndi pepala la HEPA, pepala lomwe limagwiritsidwa ntchito popanga fyuluta ya HEPA.Kaya magwiridwe antchito a makina oyeretsera mpweya akukwaniritsa zofunikira za HEPA.
Chobisika chomwe chikuseweredwa apa ndikutayikira.Ngakhale zosefera zambiri za HEPA zimagwira ntchito bwino, kapangidwe kanyumba kazinthu zambiri zoyeretsera mpweya sizowoneka bwino.Izi zikutanthauza kuti mpweya wakuda wosasefedwa umadutsa mozungulira fyuluta ya HEPA kudzera m'mipata yaying'ono, ming'alu ndi mipata yozungulira chimango cha fyuluta ya HEPA yokha kapena pakati pa chimango ndi nyumba yoyeretsa.
Chifukwa chake ngakhale oyeretsa mpweya ambiri amati zosefera zawo za HEPA zimatha kuchotsa pafupifupi 100% ya tinthu tating'onoting'ono tomwe timadutsamo.Koma nthawi zina, mphamvu yeniyeni ya mapangidwe onse oyeretsa mpweya imakhala pafupi ndi 80% kapena kuchepera, kuwerengera kutayikira.Mu 2015, National Standard GB/T18801-2015 "Air Purifier" idalengezedwa mwalamulo.Izi zakhala zikuyenda bwino, komanso zikutanthauza kuti makampani oyeretsa mpweya alowa munjira yokhazikika, yokhazikika komanso yotetezeka, kuwongolera bwino msika ndikuletsa mabodza.
Oyeretsa mpweya a LEEYO amawongolera nkhaniyi ali ndi chitetezo chokwanira, ndi mapangidwe opangidwa kuti achepetse kapena kuthetsa kutayikira kuti zitsimikizire kuti makina athu a HEPA akugwira ntchito bwino.
3. NKHAWA NDI GESI KOMANSO KUNUKA?
Mosiyana ndi tinthu tating'onoting'ono, mamolekyu omwe ali ndi mpweya, fungo, ndi zinthu zosasinthika (VOCs) si zolimba ndipo zimatha kuthawa maukonde awo mosavuta ngakhale ndi zosefera za HEPA.Kuchokera pa izi, zosefera za kaboni zomwe zimapangidwira zimatengedwanso.Kuonjezera zosefera za kaboni zolumikizidwa mu makina osefera a mpweya zitha kuchepetsa kwambiri kuwonongeka kwa mpweya woipa monga fungo, toluene, ndi formaldehyde m'thupi la munthu.
Kodi zoseferazi zimagwira ntchito bwanji?Ndizosavuta kuposa momwe mungaganizire:
Pamene chipika cha kaboni (monga makala) chikalowa mpweya wambiri.
Ma pores osawerengeka olimba amatsegulidwa pamtunda wa kaboni, womwe umakulitsa kwambiri gawo la kaboni.Panthawiyi, malo a 500g a carbon activated akhoza kukhala ofanana ndi mabwalo a mpira wa 100.
Mapaundi angapo a carbon activated amasanjidwa mu "bedi" lathyathyathya ndipo amapakidwa muzosefera zomwe zimatembenuza mpweya kudzera pa bedi la kaboni.Pakadali pano mpweya, mankhwala ndi mamolekyu a VOC amalowetsedwa mu ma pores a kaboni, zomwe zikutanthauza kuti amamangiriridwa kudera lalikulu la makala.Mwanjira iyi, mamolekyu a VOC amasefedwa ndikuchotsedwa.
Activated carbon adsorption ndiyo njira yomwe imakonda kwambiri kusefa mpweya ndi zowononga mankhwala kuchokera ku mpweya wagalimoto ndi njira zoyaka.
LEEYO air purifiersadapangidwa kuti azikulitsa kugwiritsa ntchito makala oyaka ngati mukukhudzidwa kwambiri ndi mpweya wophikira kapena fungo la ziweto kuposa kuwononga tinthu m'nyumba mwanu.
Pomaliza
Tsopano mukudziwa kuti zinthu zoyeretsa mpweya wabwino ndi:
HEPA media for particle kusefera
Sefa yosindikizidwa ndi nyumba zoyeretsa popanda kutayikira kwadongosolo
Activated carbon for gas and fungo kusefera
