1.HEPA sefa tekinoroji
HEPA (Yakanyanya kushanda zvakanaka particulate air filter), kureva kuti, yakakwira mhepo sefa, HEPA inoratidzwa nemhepo inogona kupfuura, asi zvimedu zvakanaka hazvigone kupfuura. Yayo yepamusoro-soro sisitimu inogona kuderedza density yechikamu kusvika miriyoni imwe nguva yeyakajairika mhepo yemukati.
Mufananidzo 1 Nheyo yeHEPA yekuchenesa mhepo
Iyo giredhi yesefa inotsamira pane sefa particle size yefirita layer uye kusefa kunyatsoita. Dzimwe nguva dzakaoma dzinoda huwandu hwepamusoro hwekusefa, dzakadai semakamuri ekushanda ezvokurapa, semiconductor kugadzira miti, nezvimwewo Asi kune dzakawanda zviitiko, mafirita epakati uye epamusoro-grade anogona kufunga nezvekuenzana kwekugadzirisa kushanda uye kufamba kwemhepo. Mushure mekuferefeta, takasarudza HEPA13 giredhi mafirita (magiredhi emasefa anosanganisira magiredhi esefa: H11-H14, U15, U16 (EN1822)) kuchenesa mhepo muzvishandiso zveveruzhinji.
2. Chii chinokonzerwa nemwaranzi yeultraviolet pavhairasi nemabhakitiriya?
Chiedza chezuva chine mwenje weavelengths akasiyana, kubva kune infrared (kupisa) kusvika kuchiedza chinooneka kusvika kune ultraviolet (kupisa kwezuva). Ongororo dzekuyedza dzakaratidza kare kuti ultraviolet mwaranzi inogona kunyatsoparadza utachiona hunotapukira. Kunyanya, ultraviolet mwaranzi yakakamurwa kuita mitsara mitatu, uye kuderera kwewavelength, kunowedzera simba. UV-A inogona kukonzera kutsvuka kweganda, uye nekufamba kwenguva, inomhanyisa kukuvara kweganda uye kuchembera. Ultraviolet-B inogona kukonzera kupisa kwezuva, asi inofanirwawo kuti vanhu vekugadzira vabudise vhitamini D. Ultraviolet-C ndiyo yakanyanya simba ultraviolet band, iyo inopepetwa kunze ne ozone layer mumhepo. Kana pasina ozone layer, tinofanira kugara mumba. Izvo zvinokuvadza kune chero hupenyu huri pachena kune ultraviolet-C band.
Iyo ultraviolet-C bhendi inogona kukuvadza DNA neRNA padanho remamorekuru. Mhedzisiro yacho inonyanya kukosha pa ultraviolet wavelengths yakatenderedza 250nm. Nokudaro, bhendi reultraviolet-C rinogona kushandiswa kuvhenekera utachiona kuuraya kana kudzivirira utachiona kuti hurege kuberekana uye kudzivirira kupararira kwechirwere.
Mufananidzo 2 Ultraviolet mwaranzi inoshandura chimiro cheDNA/RNA (Kwakabva: NASA)
Kana mercury vapor ikanakidzwa nemagetsi, inoburitsa 253.7nm ultraviolet chiedza. Izvi zvakashandiswa pamwenje wefluorescent kwenguva yakareba. Uku kuburitsa kunokonzeresa kuti phosphor yakavharidzirwa mubhawa yemwenje kuti iite fluoresce, nekudaro ichishandura ultraviolet rays kuita mwenje unooneka, unogona kushandiswa kuvhenekera. Iyo UV-inobata coating inogona kudzivirira chero inorasika mwaranzi. Mercury-based UV-C marambi anoshandisa chaiyo musimboti, asi pachinzvimbo chephosphors, anoshandisa asiri-UV-absorbing girazi, ayo anobvumira UV-C kuburitswa. Imwe yakashata yemarambi emercury ndeyekuti inoburitsawo pa185nm, inoburitsa ozone, iyo tri-molecular fomu yeokisijeni. Kunyangwe ichitidzivirira kubva kune ultraviolet mwaranzi pakakwirira uye ichiita sefungicide mune mamwe maapplication, ozone zvakare inoshatisa kufema uye inosvibisa. Naizvozvo, ma bulbs mazhinji eUV-C anobatwa kuti atore 185nm emission. Mwaranzi yeUltraviolet inogonawo kugadzirwa nemwenje-emitting diodes (LEDs), uye kugona kwayo uye hupenyu hwehupenyu huri kuramba huchivandudza.
