I ke kūʻai ʻana i kahi mea holoi lima FEEGOO, e lohe mau ʻoe i ka huaʻōlelo "HEPA kānana" i ʻōlelo ʻia e nā mea kālepa, akā ʻaʻole i ʻike nui ka poʻe e pili ana i ka kānana HEPA, a ʻo ko lākou ʻike ʻana e mau nei i ka pae haʻahaʻa o "pena kānana". .pae.

He aha ka mea holoi lima HEPA kānana?

Kāhea ʻia ka kānana HEPA ʻo HEPA kānana particulate kiʻekiʻe, ʻo ka inoa Pelekane piha ʻo High-efficiency particulate arrestance.

Hana ʻia nā kānana HEPA me ka polypropylene a i ʻole nā ​​mea hana ʻē aʻe, a ʻaʻole hiki ke holoi ʻia ka hapa nui o lākou.Hiki ke holoi ʻia me ka wai he helu liʻiliʻi o nā kānana HEPA i hana ʻia i ka PET, akā haʻahaʻa ka hopena kānana o ia mau kānana.

ʻO ka hapa nui o nā kānana HEPA i hoʻohana ʻia i ka ʻōnaehana ea hou e like me ka hōʻike ʻana ma lalo nei.I mea e hoʻonui ai i ko lākou hiki ke hoʻopaʻa i ka lepo, ua pelu ʻia ka nui o nā ʻāpana, a ua like ke ʻano me ka pepa mānoanoa.

Pehea e hana ai ka kānana HEPA mea holoi lima lima?

Hoʻopili ʻo HEPA kānana ma o 4 mau ʻano: interception, gravity, airflow a me nā ikaika van der Waals

1 ʻO ka ʻōnaehana interception ka kānana i hoʻomaopopo pinepine ʻia e kēlā me kēia kanaka.ʻO ka mea maʻamau, hoʻopili ʻia nā ʻāpana nui o 5 μm a me 10 μm a "sieved".

2. Ma lalo o ka mana o ka umekaumaha, e hoemi ana na mea lepo me ka leo liilii a me ka ili ki'eki'e i ko lakou holo ana ma ka HEPA, a e noho maoli ma ka HEPA filter e like me ka sediment e poho ana i lalo o ka muliwai.

3 ʻAʻole i ulana ʻia ka pale kānana e hana i ka nui o nā vortices ea, a hoʻopili ʻia nā ʻāpana liʻiliʻi ma ka pale kānana HEPA ma lalo o ka hana a ka makani makani.

4 Ke hana nei nā ʻāpana ultrafine i ka neʻe Brownian e pā i ka papa fiber HEPA, a hoʻomaʻemaʻe ʻia e ka mana o van der Waals ikaika.No ka laʻana, hoʻomaʻemaʻe ʻia nā mea lawe virus ma lalo o 0.3 μm ma lalo o ka mana o kēia ikaika.

ʻO ka ikaika o Van der Waals: ka ikaika intermolecular, e pili ana i ka ikaika e noho ana ma waena o nā molekala (mole) a me nā mole a i ʻole ma waena o nā kinoea hanohano (noble gas) a me nā ʻātoma (nā ʻātoma).

HEPA kānana helu

Lohe mau au i kekahi e ʻōlelo ana "ʻo ka kānana aʻu e hoʻohana ai ʻo H12", no laila he aha ke ʻano loiloi "H12" ma aneʻi?

E like me ka EU EN1882 maʻamau, e like me ka pono kānana, hoʻokaʻawale mākou i ka kānana HEPAl i 5 mau māka: kānana koʻikoʻi, kānana pono waena, kānana sub-high-efficiency, kānana HEPA kiʻekiʻe a me ka kānana ultra-high-efficiency.

ʻO kahi kānana me ka pono kānana i ʻoi aku ma mua o 99.9% no nā ʻāpana me ka nui o 0.3 μm i kapa ʻia ʻo H12.

ʻO nā kuhi hewa ʻole o nā kānana HEPA holoi lima

Manaʻo 1: ʻO ka nui o ka nui o nā mea ʻāpana, ʻoi aku ka maʻalahi o ka wehe ʻana e HEPA?

ʻIkepili: ʻO ke kumu hoʻomaʻemaʻe o ka kānana HEPA ʻaʻole ia e kānana i nā ʻāpana ʻoi aku ka nui ma mua o ka mesh e like me ke kānana e hoʻomaʻemaʻe i ka ea.Akā, ke hilinaʻi nei ia i ka ikaika van der Waals ma waena o nā ʻāpana maikaʻi a me ka kānana e hana i ka hopena adsorption, a he maikaʻi kāna kānana maikaʻi no nā ʻāpana ma luna o 0.5 μm a ma lalo o 0.1 μm.

Hana nā ʻāpana ma lalo o 0.1 μm i ka neʻe Brownian.ʻOi aku ka liʻiliʻi o ka ʻāpana, ʻoi aku ka ikaika o ka neʻe Brownian, a ʻoi aku ka nui o ka manawa i paʻi ʻia, ʻoi aku ka maikaʻi o ka hopena adsorption.

A ʻo nā ʻāpana ma luna o 0.5μm e hana i ka neʻe inertial, ʻoi aku ka nui o ka nui, ʻoi aku ka nui o ka inertia, a ʻoi aku ka maikaʻi o ka hopena kānana.

ʻO ka ʻokoʻa, ua paʻakikī nā ʻāpana me ke anawaena o 0.1-0.3 μm e wehe i ka HEPA.ʻO kēia ke kumu e wehewehe ai ka ʻoihana i ka māka kānana HEPA me ka helu kānana o nā ʻāpana 0.3μm.

Misunderstanding 2: ʻO ka hoʻomaʻemaʻe maikaʻi o HEPA no 0.3μm microparticles hiki ke hōʻea ma mua o 99.97%, no laila ʻaʻole maopopo kona hopena hoʻomaʻemaʻe ma 0.1μm microparticles, pololei?

ʻIkepili: E like me ka hoʻomaopopo ʻana, ʻoi aku ka maʻalahi o ka PM0.3 i ka pale ʻana i ka kānana HEPA, no ka mea ʻoi aku ka liʻiliʻi o ka mana o van der Waals.No laila, ʻoi aku ka maikaʻi o kahi kānana me ka hopena 99.97% ma PM0.3 ma PM0.1.ʻAe, ʻo 99.99%.

Myth 3: ʻO ke kiʻekiʻe o ka pono kānana HEPA, ʻoi aku ka maikaʻi?

Nānā: He nui loa kekahi mea.ʻO ke kiʻekiʻe o ka pono kānana HEPA, ʻoi aku ka nui o ke kūʻē ʻana, a e hoʻemi ʻia ka nui o ka ea.Ke emi ka leo ea, e emi iho ka nui o ka hoomaemae ana i ka manawa hookahi, a e emi iho ka pono o ka hoomaemae ana.

No laila, ʻo ka hui pū wale ʻana o ka peʻahi, kānana a me ka hoʻolālā ea ea hiki ke hoʻokō i kahi kumu hoʻohālike maikaʻi loa.

ʻEhia mau manawa e hoʻololi ʻia ai ka kānana HEPA mea holoi lima?

ʻO ka hope, hoʻi i kahi nīnau e hopohopo nei nā mea a pau, ʻehia ka manawa e pono ai ke hoʻololi i ka kānana HEPA?

ʻO ka hōʻailona koʻikoʻi no ka hoʻoholo ʻana i ke ola lawelawe o ka kānana ʻo ia ka paʻa lepo.ʻO ka ʻikepili koʻikoʻi e pili ana i ka hiki ke hoʻopaʻa i ka lepo ka wahi hoʻonui o ka pale kānana.ʻOi aku ka nui o ka hoʻonui ʻia o ka pale kānana, ʻoi aku ka kiʻekiʻe o ka paʻa lepo a ʻoi aku ka lōʻihi o ka pale kānana.

ʻO ka mana paʻa lepo e pili ana i ka nui o ka hōʻiliʻili o ka lepo i ka wā e hiki ai ke kū'ē ma muli o ka hōʻiliʻili o ka lepo i kahi waiwai i ʻōlelo ʻia (maʻamau 2 mau manawa o ke kūʻē mua) ma lalo o ka hana a kekahi leo ea.

Akā no nā mea hoʻohana maʻamau, ʻo ke kumu no ka hoʻoholo ʻana i ka hoʻololi ʻana o ka kānana e nānā me ka maka ʻōlohelohe.

He mea ʻepekema ʻole ka hoʻokolokolo inā pono e hoʻololi ʻia ka kānana e ke ʻano o ka nānā maka ʻōlohelohe.Hiki iā ia ke hoʻohana nui i ka kānana, e hoʻohaumia i ka lua, a hiki ke "hoʻomaha" i ka kānana ma mua me ka ʻole e hoʻonui i kona waiwai hoʻohana.

Hoʻohana ʻo FEEGOO i ka Gaussian fuzzy algorithm e helu i ka hoʻopau ʻana o ka lepo o ka kānana, a paipai i nā mea kūʻai aku e hoʻololi i ka kānana kiʻekiʻe o ka mea holoi lima i hoʻokahi manawa i kēlā me kēia ʻeono mahina.
