Hoʻomaopopo i ka HEPA Air Filtration

ʻOiai ua hoʻohana ʻia ka kānana ea HEPA mai ke Kaua Honua II, ua ulu nui ka hoihoi a me ke koi ʻana i nā kānana ea HEPA i nā mahina i hala iho nei ma muli o ka coronavirus. No ka hoʻomaopopo ʻana i ke ʻano o ka kānana ea HEPA, pehea e hana ai, a pehea e hiki ai ke kōkua i ka pale ʻana i ka hoʻolaha ʻana o COVID-19, ua kamaʻilio mākou me Thomas Nagl, nona ka Filcom Umwelttechnologie, kahi hui kānana ea nui ma Austria.

He aha ka HEPA Air Filtration?

He acronym ʻo HEPA no ka hoʻopaʻa ʻana i nā mea ʻāpana kiʻekiʻe, a i ʻole ka kānana ea. "ʻO ia hoʻi, i mea e hoʻokō ai i ka maʻamau HEPA, pono e hoʻokō kahi kānana i kahi kūpono kūpono," wehewehe ʻo Nagl. "Ke kamaʻilio nei mākou e pili ana i ka pono, ke kamaʻilio pinepine nei mākou e pili ana i kahi māka HEPA o H13 a i ʻole H14."

Aia ʻo H13-H14 HEPA i ka papa kiʻekiʻe loa o ka kānana ea HEPA a ua manaʻo ʻia ʻo ia ka pae lapaʻau. "HEPA hiki ke wehe i ka 99.95% o nā ʻāpana a pau o ka lewa me ke anawaena he 0.2 microns, a ʻo ka HEPA grade H14 e wehe i 99.995%," wahi a Nagl.

"ʻO ka 0.2 micron ka nui paʻakikī loa o kahi ʻāpana e hopu ai," wehewehe ʻo Nagl. "Ua ʻike ʻia ʻo ia ʻo ka nui loa o ka penetrating particle size (MPPS)." No laila, ʻo ka pākēneka i hōʻike ʻia ʻo ia ka ʻoi aku ka maikaʻi o ke kānana, a ua paʻa nā ʻāpana i ʻoi aku ka nui a i ʻole ka liʻiliʻi ma mua o 0.2 microns me ka ʻoi aku ka maikaʻi.

'Ōlelo Aʻo: ʻAʻole pono e huikau nā helu H o ʻEulopa me nā helu MERV US. Ua like ka HEPA H13 a me H14 ma ʻEulopa me kahi MERV 17 a i ʻole 18 ma ʻAmelika Hui Pū ʻIa.

He aha nā kānana HEPA a pehea e hana ai?

Hana ʻia ka hapa nui o nā kānana HEPA me nā fiber aniani interlaced e hana i kahi pūnaewele fibrous. "Akā naʻe, ʻo nā hana hou i ka kānana HEPA me ka hoʻohana ʻana i nā mea synthetic me kahi membrane," hoʻohui ʻo Nagl.

Hoʻopaʻa ʻia nā kānana HEPA e hopu a hoʻoneʻe i nā ʻāpana ma o ke kaʻina kumu o ka hoʻopaʻa ʻana a me ka hopena pololei, akā ma o nā mīkini paʻakikī ʻē aʻe i kapa ʻia ʻo interception a diffusion, i hoʻolālā ʻia e hopu i ka hapa nui o nā ʻāpana.

He aha nā ʻāpana e hiki ke hoʻoneʻe ʻia i kahi kānana HEPA mai ke kahawai?

Hoʻopili ka maʻamau HEPA i nā ʻāpana liʻiliʻi loa, me nā mea i ʻike ʻole ʻia e ka maka o ke kanaka, akā pōʻino i ko mākou olakino, e like me nā maʻi maʻi a me nā maʻi bacteria. No ka mea, ʻo ka pūnaewele o nā fiber i loko o kahi kānana HEPA lāʻau lapaʻau he paʻa loa, hiki iā lākou ke paʻa i nā ʻāpana liʻiliʻi loa i ka helu kiʻekiʻe loa, a ʻoi aku ka maikaʻi o ka wehe ʻana i nā mea ʻino mai ke kaiapuni.

No ka hiʻohiʻona, aia ka lauoho kanaka ma waena o 80 a 100 microns ke anawaena. ʻO ka pollen he 100-300 microns. ʻOkoʻa nā maʻi ma waena o >0.1 a me 0.5 microns. Eia nō naʻe, he mea nui e hoʻomanaʻo i kēlā, ʻoiai ʻo ka H13 HEPA i manaʻo ʻia he 99.95% maikaʻi i ka wehe ʻana i nā ʻāpana i ka lewa i ke ana ʻana he 0.2 microns, ʻo ia ka hopena maikaʻi loa. Hiki iā ia ke wehe i nā ʻāpana liʻiliʻi a nui aʻe. I ka ʻoiaʻiʻo, ʻoi aku ka maikaʻi o ke kaʻina o ka diffusion no ka wehe ʻana i nā ʻāpana ma lalo o 0.2 microns, e like me ka coronavirus.

ʻO ka wikiwiki hoʻi ʻo Nagl e wehewehe ʻaʻole ola nā maʻi iā lākou iho. Pono lākou i mea hoʻokipa. "Hoʻopili pinepine nā maʻi i nā ʻāpana lepo maikaʻi, no laila hiki i nā ʻāpana nui i ka lewa ke loaʻa nā maʻi ma luna o lākou. Me kahi kānana HEPA pono he 99.95%, hopu ʻoe iā lākou a pau.

Ma hea kahi i hoʻohana ʻia ai nā kānana HEPA H13-H14?

E like me kāu e manaʻo ai, hoʻohana ʻia nā kānana HEPA lāʻau lapaʻau i nā halemai, nā hale kiʻiʻoniʻoni, a me nā mea hana lāʻau lapaʻau. “Hoʻohana ʻia lākou i nā lumi kiʻekiʻe a me nā lumi hoʻokele uila, kahi āu e makemake ai i ka ea maʻemaʻe. No ka laʻana, i ka hana ʻana i nā pale LCD, "hoʻohui ʻo Nagl.

Hiki ke hoʻonui ʻia kahi ʻāpana HVAC i HEPA?

"Hiki ia, akā hiki ke paʻakikī ke hoʻihoʻi hou i kahi kānana HEPA i kahi ʻōnaehana HVAC e kū nei ma muli o ke kiʻekiʻe o ke kaomi ʻana o ka mea kānana," wahi a Nagl. I kēia manawa, paipai ʻo Nagl i ka hoʻokomo ʻana i kahi ʻāpana recirculation ea e hoʻihoʻi i ka ea i loko me kahi kānana H13 a i ʻole H14 HEPA.
