ASHRAE "Sefa uye mhepo yekuchenesa tekinoroji chinzvimbo" gwaro rakakosha kududzira

Mukutanga kwa2015, American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) yakaburitsa Position Pepa pa.Masefa uye Mhepo YekuchenesaTechnologies.Makomiti akakodzera akatsvaga data iripo, humbowo, uye zvinyorwa, zvinosanganisira zvinyorwa zve ASHRAE, pamusoro pekushanda kwehunyanzvi husere hunosanganisira mechanical media filtration, magetsi mafirita, adsorption, ultraviolet light, photocatalytic oxidation, air cleaners, ozone, uye kufefetedza.Indoor occupant hutano mhedzisiro, mhedzisiro yenguva refu, uye zvisingakwanisi zvinoongororwa zvizere.

Pepa renzvimbo rine mapoinzi maviri akasiyana:

1. Tichifunga nezvekuipa kweozone uye maitiro ayo ekuita pane hutano hwevanhu, ozone haifanirwe kushandiswa kuchenesa mhepo munzvimbo dzemukati.Kunyange kana ozone isingashandisi kucheneswa, kana chigadzirwa chekuchenesa chinogona kuunza huwandu hwakawanda hweozone panguva yekushanda, chiyero chepamusoro chekuchenjerera chinofanira kupiwa.

2. Yese tekinoroji yekusefa uye yekuchenesa mweya tekinoroji inofanirwa kupa dhata rekubviswa kwezvinosvibisa zvichibva panzira dzazvino dzekuyedza, uye kana pasina nzira yakakodzera, panofanirwa kuve nekuongororwa nesangano rechitatu.

Gwaro rinosuma imwe neimwe yematekinoroji masere.

1. Mechanical filtration kana porous media filtration (Mechanical filtration kana Porousmedia particle filtration) ine mhedziso iri pachena yekusefa pane tunhu uye inobatsira kuhutano hwevanhu.
2. Humbowo hunoratidza kuti nekuda kwehukama neakawanda ehurumende parameters, kubviswa kwemagetsi mafirita pane tunhu tunhu mumhepo kunopa huwandu hwakakura: kubva pakusashanda kusvika kune hunobudirira.Uyezve, mhedzisiro yayo yenguva refu inoenderana nemamiriro ekuchengetedza mudziyo.Sezvo electrofilters kushanda musimboti ionization, pane ngozi ozone chizvarwa.
3. Sorbent ine pachena kubvisa mhedzisiro pane gasi zvinosvibisa.Zvidzidzo zvakaratidza kuti pfungwa yevanhu yekunhuwa ine ongororo yakanaka pakubvisa kwayo.Zvisinei, kuchine humbowo husina kukwana hwakananga kana hunobatsira kuutano.Nekudaro, adsorbents emuviri haashande zvakaenzana pane zvese zvinosvibisa.Iine simba guru pane isiri-polar organic matter, high boiling point, uye hombe molecular weight gaseous pollutants.Kune yakaderera kuwanda kwezvinhu zvine huremu hwemamolecular pasi pe50 uye yakakwirira polarity, senge formaldehyde, methane uye ethanol, hazvisi nyore kushambadza.Kana iyo adsorbent yekutanga yakashambadza zvinosvibisa ine yakaderera molecular uremu, polarity uye yakaderera boiling point, kana ikasangana ne-non-polar organic matter, high boiling point, uye gasi rinosvibisa nehombe molecular uremu, inoburitsa (desorb) chikamu chezvakamboshambadza zvinosvibisa. , ndiko kuti, kune adsorption makwikwi.Uyezve, kunyange zvazvo physisorbents ichidzokororwa, iyo hupfumi inofanirwa kutariswa.
4. Zvimwe zvidzidzo zvakaratidza kuti photocatalytic oxidation inoshanda mukuora organic matter uye microorganisms, zvisinei, pane zvakare humbowo hwekuti haina mhedzisiro.Photocatalyst inoshandisa ultraviolet rays kuti irradiate pamusoro peiyo catalyst kukurudzira kuparara kwezvinhu zvinokuvadza pairi kuita carbon dioxide nemvura, asi mhedzisiro yayo inoenderana nenguva yekusangana, huwandu hwemhepo, uye mamiriro epamusoro eiyo catalyst.Kana maitiro asina kukwana, zvimwe zvinhu zvinokuvadza zvakadai se ozone uye formaldehyde zvinogonawo kugadzirwa.
5. Tsvagiridzo inoratidza kuti ultraviolet mwenje (UV-C) inogona kushanda mukudzivisa kuita kwezvinosvibisa kana kuzviuraya, asi chenjerai inogona kuitika ozone.
6. Ozone (Ozone) inokuvadza kuhutano hwevanhu.Muganho unobvumidzwa wekutarisa wakatsanangurwa ne ASHRAE Environmental Health Committee muna 2011 i10ppb (chikamu chimwe pa100,000,000).Nekudaro, parizvino hapana kubvumirana pamutengo wemuganho, saka zvinoenderana neiyo precautionary musimboti, tekinoroji yekuchenesa isingaburitse ozone inofanira kushandiswa zvakanyanya sezvinobvira.
7. Mhepo yekuchenesa (Packaged air cleaner) chigadzirwa chinoshandisa tekinoroji imwechete kana yakawanda yekuchenesa mhepo.
8. Kufefetera inzira inoshanda yekubvisa zvinosvibisa mukati kana mhepo yekunze yakanaka.Kushandisa kusefa uye humwe hunyanzvi hwekuchenesa mhepo kunogona kuderedza kudiwa kwemhepo. Kana mweya wekunze wasvibiswa, magonhi nemahwindo zvinofanirwa kuvharwa.

Apo iyomhepo yekunzeyakanaka, kufefetera pasina mubvunzo ndiyo yakanakisa sarudzo.Zvisinei, kana mhepo yekunze yakasvibiswa, kuvhura mahwindo emhepo kunofuridzira kunze zvinosvibisa mumba, zvichiwedzera kuipa kwekusvibiswa kwemukati kwezvakatipoteredza.Naizvozvo, magonhi nemahwindo zvinofanirwa kuvharwa panguva ino, uye yakakwirira-inotenderera mweya yekuchenesa inofanira kuvhurwa kuti ikurumidze kubvisa zvinosvibisa mukati memukati.

Tichitarisa kukuvadzwa kweozone kuhutano hwevanhu, ndapota chenjerai nezve zvigadzirwa zvinoshandisa high-voltage electrostatic tekinoroji kuchenesa mweya, kunyangwe zvigadzirwa zvakadaro zvikaburitsa mishumo yekuongorora kubva kumasangano ekuongorora.Nekuti zvigadzirwa zvakaedzwa murudzi urwu rwekuongorora rondedzero ese mashini matsva, hunyoro hwemhepo panguva yebvunzo hauna kuchinja.Kana chigadzirwa chacho chichishandiswa kwenguva yakati, guruva guru rinoungana muchikamu chepamusoro-voltage, uye zviri nyore kwazvo kubudisa kubuda kwechiitiko, kunyanya munzvimbo ine hunyoro kumaodzanyemba, uko hunyoro hwemhepo hunowanzoita se. yakakwirira se90% kana pamusoro, uye high-voltage discharge phenomenon inowanzoitika.Panguva ino, iyo yemukati Iyo ozone concentration iri nyore kupfuura mwero, iyo inokuvadza zvakananga hutano hwevashandisi.

Kana iwe wakatenga chigadzirwa chine high-voltage electrostatic tekinoroji (air purifier, fresh air system), kana iwe dzimwe nguva uchinzwa kunhuhwirira kunhuhwirira kwehove paunenge uchiishandisa, unofanirwa kungwarira panguva ino, zviri nani kuvhura hwindo. kufefetera uye woivhara pakarepo chigadzirwa.
