He aha te ERV
Whakaora Pūngao Pūwero hau
Ko te Pūngao Whakaora Pūngao (ERV) he momo mīhini e penapena ana i te pūngao Pūnaha Whakahaurangi e whakamahi ana i ngā hangarau whakaora pūngao (te matua pereti erv, te wira hurihuri me ētahi atu) hei whakaora i te wera me te makuku mai i te hau. Ka tangohia e te rere ōrite o te pūnaha ERV te hau tawhito mai i roto, me te tuku i te hau hou kua tātarihia ki roto i te whare, me te whakapai ake i te kounga o te hau o roto. Ka whakamataohia i mua te hau mahana me te haukū o waho i te raumati mā te kaha o te hau makariri o roto e puta atu ana. I te takurua, ka whakamahanahia i mua te hau o waho (makariri me te maroke) me te haukū mai i te hau mahana e puta atu ana i roto i te rūma. He tikanga tēnei ka taea e koe te pupuri i tētahi taiao whakamarie hei noho mā te pupuri i te whakamahinga o ngā taputapu HVAC me te whakamahinga pūngao kia iti.
Ko tētahi o ngā painga nui o te pūnaha ERV ko te whakamahinga pai o te pūngao me te kore e ngaro te pūngao, kia kore ai tō pūnaha hauhautanga me ō taputapu whakapūngao e mahi nui, ka meinga... Ngā Pūnaha Hvac iti ake. Ka ārai hoki i te puehu, i ngā mate pāwera me ētahi atu mea kino kei rere i te hau, ka āwhina i te karo i te rere pea o te hau tawhito i roto. Nā te mea e noho ana te tangata i roto i te whare neke atu i te 90%, ā, e rima ngā wā ka nui ake te parahanga o roto i te parahanga o waho. Ka oati te pūnaha ERV ka nui rawa te roanga o tō rātou oranga i roto i te taiao taurite, pumau, ka waihanga i te rere tonu o te hau o waho me te hau hou ki roto i ngā whare hei whakapai ake i te hauora, te mahi me te hua o te tangata.
He pēhea te mahi?
Ko ngā Pūwero Whakaora Pūngao (ERV) he taputapu e whakawhiti ana i te wera me te makuku i waenga i te hau hou e tomo mai ana me te hau putanga hei whakapai ake i te whai huatanga o te pūngao me te pupuri tonu i te whakamarie wera. Ko te ariā matua o muri i ngā ERV ko te whakawhiti wera me te makuku i waenga i ngā hau e rua, ko tētahi nō roto i te whare, ko tētahi nō waho. Hei tauira, i roto i tētahi tono e rere ana ngā hau e rua i ngā pāmahana rerekē, hei tauira 70 °F me te 0 °F, ka whakawhiti ngā ERV i te wera kia whakamatao te hau o roto, kia wera hoki te hau o waho, ā, kia mau tonu ai ngā āhuatanga whakamarie i roto i te whare me te whakaiti i te pūngao e hiahiatia ana mō te whakamahana, te whakamatao rānei.
Ka tangohia e te matua ERV te wera me te haumākū mai i te hau o waho e tomo mai ana i mua i te whakaurunga ki roto i te whare. Pērā tonu te mahi a te takurua, i te mea ka whakamahanahia e te pūnaha te hau makariri e tangohia mai ana i waho me te hau mahana e puta atu ana i te whare, ka pai ake te ahua, ka whakaitihia hoki te nui o te kaha e hiahiatia ana hei whakamahana i te hau e tomo mai ana. Ahakoa kāore e taea te whakahoki mai i te kaha katoa me ngā ERV, he tino pai te whakaora, ā, kua whakamanahia te mahi e te AHRI (Air Conditioning, Heating and Refrigeration Institute) ā, ka rerekē i runga i ngā āhuatanga o te taiao.
He mea nui anō hoki ngā ERV mō te IAQ (Tohu Kounga Hau). Ka tātarihia e rātou ngā poke pēnei i ngā VOC, ngā hau paitini, me ngā mate pāwera e tangohia ana te hau mai i ngā tāonga whare, peita, whāriki, me te āheinga o te tari. Ka taea te whakauru i ngā ERV ki ngā kāinga, ki ngā whare arumoni nui ake, hei wāhanga motuhake rānei o tētahi pūnaha HVAC. Ka whakapai ake ngā pūnaha hauhautanga taurite i te IAQ i ētahi atu momo hauhautanga, pēnei i te putanga hau, te tuku hau rānei, mā te tuku i te whakawhiti hau taurite hei tango i ngā poke hohe, ahakoa te taiao, te āhuarangi rānei.
Ngā Painga o te Whakamahi i te ERV
I roto i ngā whare hou, he mea nui te mahi a ngā mīhini whakaora pūngao (ERV) ki te whakapai ake i te kounga o te hau o roto (IAQ) me te whakamarie whānui. He maha ngā wā ka nui ake te poke o te hau o roto i te hau o waho — tae atu ki te 100 ngā wā i ētahi wā, e ai ki te US Environmental Protection Agency (EPA) — me ngā pānga kino ki te hauora. He tino kino tēnei raruraru i muri i te COVID-19, nā te mea ka taea e te korenga o te hauhautanga te kohikohi i ngā aerosol huaketo kino ki roto. I te mea kua hangaia ngā whare kia pai ake te hauhautanga hei ngana ki te penapena pūngao, me tika te hauhautanga hei pupuri i a tātou kia haumaru, engari kāore e taea te whakamahi i ngā tikanga tuku iho pēnei i te whakatuwhera i ngā matapihi, inā koa i te wera nui, i te makariri rānei.
Koinei te wāhi e puta mai ai ngā mīhini whakaora pūngao (ERV) hei āwhina — ka taea te whakawhiti wera me te makuku i waenga i te hau e tomo mai ana me te hau e puta atu ana me te tino whai hua. I te raumati, ka whakamatao, ka tango i te makuku o te hau o waho; i te takurua, ka whakamahana, ka whakamakuku i mua i te kawe ki roto. Ka whakaitihia e tēnei ngā poke, tae atu ki te formaldehyde, ngā mate pāwera, me ngā paitini, ka hua ake he pai ake te IAQ me te penapena pūngao. Ka whakaratohia e ngā ERV he huarahi whai hua hei whakataurite i te pūngao me te whakahaere i te makuku o roto, nā te mea ka whakahokia mai e rātou te makuku i runga ake i te whakamahana me te whakamatao. Ka taea hoki e rātou te āwhina i ngā kamupene ki te whakatutuki i ngā ture hanga me ngā paerewa pumau me te arotau i ngā utu whakahaere mā te whakapai ake i te whai huatanga o te hauhautanga me te kore e whakararu i ngā penapena pūngao.
He aha te rerekētanga i waenga i te ERV me te HRV?
Ka taea e te ERV te whakahoki mai i te wera — te pūngao aro — me te haumākū — te pūngao huna — mai i te putanga hau, nō reira, he iti ake te pūngao e whakamahia ana i roto i te whakatikatika i te hau o waho e uru ana ki roto i te whare me te taiao o roto e whanake ana, ā, ka puta mai i roto i te hekenga i roto i ngā taumata whakamarie. Ko te HRV, i tetahi atu taha, ka whakahoki noa i te wera — kāore e whakahaere i te makuku. Ko te tikanga ko ngā ERV i roto i te āhuarangi haumākū, engari ko ngā HRV he pai ake te mahi i roto i ngā āhuatanga makariri, maroke, kāore e nui te āwangawanga mō te whakahaere makuku.
Me whai ERV ahau?
He mea nui ngā ERV hei whakatutuki i te whakapainga pūngao-pai i roto i te kounga hau o roto (IAQ) i ngā rā i muri i te COVID-19. Ko ngā ERV matua-enthalpy o Airwoods e tohuhia ana e te pai o te mahi, te ngāwari, te pono, te hau ma me te hauora ake, me te ārai kaha ake ki ngā mate urutā. Ka whakaratohia hoki e ēnei pūnaha he penapena pūngao, e āwhina ana i te whakaiti i te utu mā roto i ngā penapena pūngao e whakaratohia ana e rātou. Tirohia a Airwoods Energy Recovery Outdoor Air Solutions me ngā waeine tuanui DOAS e whakanui ake ana i tō kawenga hauhautanga mā te wetewete i ngā kawenga hau o waho me roto. Ka whakauruhia e ngā pūnaha te hau o waho kua whakamarokehia ka taea te whakahoki mai i te pūngao hei whakapai ake i te IAQ, te whakamarie, me te penapena pūngao.
