Kia pono tātou: he moemoeā kino te whakahaere i tētahi hōtēra. Me whai whakamarie tonu ngā manuhiri.–hau hou, pāmahana tino pai, rūma marino. Engari ko te pupuhi i taua hau hou me te tuku i te hau tawhito ko te tikanga he whakamahana tonu, he whakamatao rānei i te hau o waho mai i te tīmatanga.'He rite ki te waiho i te tatau o te rūma pupuri taonga kia tuwhera tonu, me te mātakitaki i tō moni e rere ana i waho me te putanga hau. Ka rongo koe i tēnā i ia marama i runga i te pire ratonga. Engari, me pēhea mēnā ka taea e koe te whakahoki mai i te nuinga o taua kaha? Whakauruhia te toa ngaro o te whai huatanga o te hōtēra: tePūwero Whakaora Wera (HRV)) me tōna whanaunga whakahaere-haumākū, te Energy rāneiPūwero Whakaora (ERV)Ehara tēnei i te mea he taputapu horoi taiao noa iho; he panonitanga nui tēnei ki te whakahaere a ngā hōtēra atamai i te hau, i te pūngao, me te hua o ā rātou mahi.

 

He aha te kore utu o te hau hou (ina koa i roto i ngā hōtēra)

He pai te hiri o ngā hōtera hou mō te whai huatanga, e kore e mau noa i te hau whakamahana engari me ngā haunga, te haumākū, te CO2, me ngā mea kino mai i ngā hua horoi, te tunu kai, me te tangata. Me huri nui ngā ture hanga whare me ngā tumanakohanga a ngā manuhiri ki ngā hau hou.–E whakamārama ana te Paerewa ASHRAE 62.1 i ngā whakaritenga, e tohu ana i te nui o ngā putu kūpiko ia meneti (CFM) mō ia rūma manuhiri me te wāhi whānui. Whakaarohia:

 

•Takurua: Hukapapa, maroke (-10°C? -20°Me whakamahana te hau o waho ki te pāmahana whakamarie 22°C, ā, kua makuku.

•Raumati: Te werawera, te haumākū (35°C me te 80% te haumākū?) me nui te whakamatao me te tango i te hau o waho.

 

He tino nui te kaha e hiahiatia ana hei whakamahana i tēnei hau hou *e hiahiatia ana*. I roto i te maha o ngā hōtera, inā koa i ngā āhuarangi tino kino, ka taea e ia te 30-50%, neke atu rānei, o te kawenga hiko HVAC katoa. He pānga tika tēnā ki te hua. Ka pau noa i ngā pūnaha tuku iho te hau tawhito, te hau whakamahana, ka kawea mai te hau o waho kāore i rongoatia, ka utua te utu hiko katoa i ia wā. He maumau noa iho. Kāore koe e maka i te wai wera tino pai ki raro i te waikeri i te wā e utu ana koe ki te whakamahana i te wai matao, e tika ana? Heoi anō, koinā'Koinei te mea e pā ana ki te pūngao hauhautanga.

 

Te HRV/ERV: Te Hopu i te Kaihanga Mawhiti

Koinei te wāhi e puta ai te mahi makutu. He pouaka atamai te HRV/ERV kei roto he matua whakawhiti wera motuhake. Kei waenganui i te rerenga hau e puta atu ana me te rerenga hau hou e tomo mai ana. Kei konei'te mātāpono matua:

 

1. Ngā Awa e Rua, Kore e Ranu: Ka tukuna *ki waho* o te whare te hau mahana, tawhito o roto (i te takurua) te hau matao rānei o roto (i te raumati). I te wā kotahi, ka kawea *ki roto* te hau hou o waho. He mea nui, kāore ēnei awa e rua e hanumi ā-tinana. Ka hongihia e ngā manuhiri te hau hou, ehara i te hau hangarua.

2. Te Whakawhiti Wera: Ka rere ngā awa mā roto i te pūtake me te tino tata, ka wehea e ngā pakitara angiangi, kawe hiko (i roto i ngā HRV) me ngā kiriuhi haurua-permeable (i roto i ngā ERV). Ka rere noa te pūngao wera mai i te awa mahana ki te awa matao mā roto i ēnei pakitara/kiriuhi.

•Te Mahi Hotoke: Ka whakamahana te hau wera i te hau hou makariri e tomo mai ana. Ka mātao ake te whare i te hau putanga, engari ka mahana ake te hau hou e tomo mai ana ki te whare, ā, he iti ake te whakamahana e hiahiatia ana mai i te kōhua, mai i te oumu rānei.

•Te Mahi Raumati: Ka whakamatao mua te hau putanga hau mātao i te hau hou wera e tomo mai ana. Ka mahana ake te putanga o te hau putanga, engari ka tomo mai te hau hou he mātao ake, he maroke ake (mō ngā ERV), ā, he iti ake te mahi e hiahiatia ana mai i te pouaka whakamatao me te whakamaroke haumākū.

3. Te Tauwehe Makuku (ERV): Koinei te mea nui hei wehewehe. Ahakoa ka tukuna noa e ngā HRV te wera *taea* (pāmahana), ka tukuna e ngā ERV te wera taea me te wera *huna* (makuku). Mā te whakamahi i ngā kiriuhi motuhake:

•Raumati: Mā te hau maroke o roto ka āwhina i te tango i te makuku mai i te hau makuku o waho. Ka tino whakaitihia te kawenga whakamaroke.

•Hotoke: Ka whakawhiti te hau haukū o roto i te hau makuku ki te hau maroke o waho, ka āwhina ki te pupuri i te taumata haukū o roto, me te whakapai ake i te whakamarie o te manuhiri (ka iti ake te kiri maroke, te ru pūmau) me te kore e hiahiatia te whakamahi kaha i ngā taputapu whakamakuku.

 

Kei tua atu i te Matua: Kia Whai Hua i te Ao Tūturu 

Ehara i te mea he pouaka makutu noa iho. Ko tētahi pūnaha HRV/ERV hōtēra kua hoahoatia paitia e whai wāhi ana ki:

 

•Pokapū, Pokapū rānei: He maha ngā hōtera nui e whakamahi ana i ngā waeine pokapū hei whakahaere i ngā papa katoa, i ngā parirau rānei mā roto i ngā paipa hiko. Tērā pea ka whakamahi ngā hōtera papai, ngā whakahounga rānei i ngā waeine pokapū iti ake, pokapū e mahi ana ki ngā rūma takitahi, ki ngā rohe iti rānei, e tuku ana i te ngāwari ake engari me nui ake ngā waeine e hiahiatia ana. Ka whai hua ngā pūnaha pokapū i ngā ōhanga tauine engari me nui te wāhi paipa hiko e hiahiatia ana. He māmā ake te tāuta i ngā waeine pokapū ki ngā whakahounga engari me tūpato te whakanoho (i ngā tuanui, i ngā pakitara o waho rānei) me ētahi atu wāhi tiaki.

•Tātari Pakari: He mea nui te tiaki i te pūtake whakawhiti wera tairongo. He mea nui ngā tātari MERV 13+ kounga teitei i *ngā awa whakauru me ngā awa whakaputanga. Ka hopukina e rātou te puehu, te hae, me ngā poke, ka ārai i te paru o te pūtake, ā, ka whakarite kia ma te tukunga o te hau. Whakaarohia ngā matūriki mai i ngā taiao tāone, ngā hae rānei e tata ana ki ngā wāhi hararei.–Mā te tātari ka taea te whakahaere pai i te pūnaha, ā, ka tiakina hoki ngā manuhiri.

•Ngā Mana Whakahaere Maamaa: Ehara ngā HRV/ERV hou i te hunga kuware. Ka honoa ngā mana whakahaere matatau ki te Pūnaha Whakahaere Whare (BMS). Ka taea e rātou:

•Whakarerekētia te tere o te hau i runga i ngā pūoko noho (hei tauira, he hononga ki ngā pūnaha whakahaere rūma), ngā taumata CO2, ngā tauira noho kua whakaritea rānei (hei tauira, te whakaiti i te tere ina takoto kau ana ngā rūma hui).

•Aroturukihia te pai o te mahi matua me te tūnga o te tātari, me te whakaoho i ngā matohi tiaki.

•Arotauhia te mahi i runga i te pāmahana me te haumākū o waho (hei tauira, te karo pea i te pūtake ina ngawari ngā āhuatanga o waho, ā, kāore e whai hua te whakaora pūngao, te whakarerekē rānei i ngā tautuhinga whakawhiti makuku ERV i ia wā).

•Whakatinanahia ngā huringa whakarewa hukapapa i roto i ngā āhuarangi tino makariri hei ārai i te hanga hukapapa i te puku mai i te makuku o te putanga hau.

•Te Whakatakotoranga Rautaki: Me wātea ngā wāhi e hiahiatia ana mō te tiaki (he maha ngā whakawhiti tātari!). Me āta wehe ngā pūwāhi whakauru me ngā pūwāhi whakaputa hau kia kore ai e poto te ara iahiko (ka mimitihia te hau whakaputa hau ki roto). Me tū ngā pūwāhi whakauru ki tawhiti atu i ngā pūtake parahanga e kitea ana pērā i ngā tauranga uta, ngā putanga hau o te kīhini, ngā wāhi momi hikareti rānei. Kaua ngā pūwāhi whakaputa hau e whakararuraru i ngā manuhiri i runga i ngā taupee, i ngā whare tata rānei.

 

Te Utu Whaitake: He aha ngā Hōtera e Hāumi Ana

Mā te haumitanga ki te hangarau HRV/ERV ka puta he hua tuturu, he hua ka taea te ine:

 

1. He Penapena Pūngao Nui: Koinei te mahi matua. Mā te whakahoki mai i te 60-85% o te pūngao wera e maumauria ana, ka whakaitihia e ngā hōtēra ā rātou utu whakamahana me te whakamatao e pā ana ki te hauhautanga. Ko ngā wā whakahokinga moni, inā koa me te pikinga o ngā utu pūngao, ka taka i roto i te 2-5 tau. E ai ki ngā pūrongo, i whakaitihia e tētahi hōtēra nui i Chicago tana whakamahinga hau maori mō te whakamahana i te hau hauhautanga mā te neke atu i te 70% i muri i te tāutanga o ngā HRV, ka penapenahia ngā tekau mano i ia tau. I Miami makuku, i whakaitihia e te tāutanga ERV i tētahi wāhi hararei takutai te wā whakahaere o te pouaka whakamatao me te pūngao whakamaroke i te wā raumati nui.

2. Whakarei ake i te whakamarie o te manuhiri: He mea nui te hau *hou* tonu. Mā ngā HRV/ERV ka nui te hauhautanga, me te kore e puta he hauhautanga whakararuraru, he rerekētanga nui rānei o te pāmahana i te taha o ngā matapihi, o ngā tatau rānei. Mā ngā ERV ka ārai i te hau maroke rawa i te takurua (ka puta te mamae me te riri o te manawa) ā, ka whakaiti i te haumākū nui i te raumati (ka ārai i te haukū). He pai ake te moe o ngā manuhiri, he mataara ake, ā, he iti ake te tūponotanga ki te whakamahi i te whakamahana, ki te amuamu rānei mō te kikī. Whakaarohia te rerekētanga i waenga i te rūma hui kua kikī, kua tawhito, me tētahi e ahua hou tonu ana, e mataara ana.

3. Te Whakapai Ake i te Kounga o te Hau o Roto (IAQ): Mā te hauhautanga tonu, e whakahaeretia ana, ka whakaitihia, ka tangohia hoki ngā poke: te CO2 mai i ngā kainoho, ngā VOC mai i ngā hua horoi, ngā taonga whare, me te haunga hau, ngā matūriki, me ngā kakara. Mā tēnei ka hangaia he taiao hauora ake mō ngā manuhiri me ngā kaimahi, ka whakaiti pea i ngā tohumate mate pāwera me te whakapai ake i te oranga whānui. I te ao whai muri i te mate urutā, ko te IAQ pai e kitea ana he mea nui ki ngā manuhiri me te painga whakataetae. Ka taea e koe te hokohoko "Kua Whakamanahia te Hau Hou."

4. Te Whakaiti i te Taumahatanga o te HVAC: Mā te whakarite i te hau e tomo mai ana, ka whakaitihia e ngā HRV/ERV te kawenga ki ngā pūnaha whakamahana me te whakamatao tuatahi (ngā poiha, ngā pouaka whakamatao, ngā papu wera, ngā oumu, ngā waeine AC). Ka hua ake tēnei ki:

•Roa te Roa o te Ora o ngā Taputapu: Kāore ngā pūnaha e mahi tonu ana i te kaha tino teitei.

•He iti iho ngā utu tiaki: He iti ake te pakaru me te haehae o ngā pūwero hiko, ngā mura, me ngā koiri.

•Te Pūmanawa mō te Whakaiti: I ngā whare hou, mā te whakaiti i te kawenga nui ka taea te whakamahi i ngā taputapu HVAC matua he iti ake, he iti ake te utu.

5. Ngā Tohu Whakapūmau: Mā te whakaiti i te whakapaunga pūngao ka whakaiti tika i te tapuwae waro o te hōtēra. Ko te whakatinanatanga o te hangarau HRV/ERV he taahiraa tūturu ki ngā whāinga whakapūmau, e kukume ana i ngā kaihaerere e aro nui ana ki te taiao, ngā kiritaki umanga me ngā mana matomato, me te whakatutuki i ngā whakaritenga ture pea.'he mahi tūturu ehara i te mea ko te tono noa ki ngā manuhiri kia whakamahi anō i ngā tauera.

 

Kei tua atu i ngā Kaupapa Taketake: Ngā Whakaaro me ngā Auahatanga

Me āta whakaaroaro kia angitu ai te whakatinanatanga o ngā HRV/ERV:

 

•HRV me te ERVKo te kōwhiringa kei runga i te āhuarangi me te whakahaere o te hōtēra. Ko te tikanga, he pai ake ngā ERV i ngā āhuarangi wera/makuku me ngā āhuarangi makariri he wero te pupuri i te makuku o roto i te takurua (pērā i ngā wāhi reti reti). Tērā pea he rawaka ngā HRV i ngā āhuarangi makariri, maroke. Ko ngā hōtēra āhuarangi whakauru te nuinga o te wā ka whai hua nui mai i ngā ERV. Whakaarohia te tauwāhi o te hōtēra: he wāhi mirimiri koraha, he wāhi hararei takutai pārūrū, he whare tira maunga rānei?

•Te Utu me te ROI o muaHe nui ake te haumitanga tuatahi (taputapu + tāutanga) i ngā pā hau hau noa. Heoi, he hua pai te penapena pūngao me ngā painga whakahaere. He mea nui te tātari utu huringa ora (me te whakaaro ki te pūngao, te tiaki, me te roa o te ora o ngā taputapu). Whakaarohia ngā whakahokinga pea mō te tāuta i ngā pūnaha whakaora pūngao.

•Hoahoa me te Tāutanga TohungaEhara tēnei i te kaupapa DIY. Mēnā he kino te hoahoa, te tāuta rānei o ngā pūnaha, ka kore pea e whai hua, ka raru te haruru, ka raru te hauhautanga, ka ngoikore hoki te tohatoha o te hau. Whakauru atu ki ngā miihini HVAC me ngā kaimahi kirimana e mōhio ana ki ngā tono HRV/ERV arumoni. Me whakarite kia tika te taurite me te whakatūnga i muri i te tāutanga. He amuamu manuhiri kei te tatari kia puta mai he pūnaha e ngunguru nui ana i waho o tētahi rūma kounga teitei.

•Te Whakapūmautanga TiakiMe whakawhiti auau ngā tātari (he maha ngā wā ia toru marama, he maha ake ngā wā i ngā taiao puehu). Me tirotirohia, me horoi hoki ngā matua i ia wā. Mā te kore e tiaki ka tere te whakaiti i te whai huatanga, ā, ka kino pea te waeine. Me whakauru tēnei ki roto i te mahere whakahaere me te tahua. Whakangunguhia ngā kaimahi hangarau mō ngā whakaritenga motuhake.

 

I te tirohanga whakamua, kei te whanake tonu te hangarau HRV/ERV o ngā hōtēra:

 

•Whakaurunga AtamaiTe whakaurunga hōhonu ake ki ngā BMS hōtēra me ngā tūāpapa IoT mō te tiaki matapae, te arotautanga wā-tūturu i runga i ngā raraunga nohonga taipitopito, me ngā tātaritanga mamao.

•Te Mahi Tahi o te Hauhanga e Whakahaerehia ana e te Tono (DCV)He tino pai te tautoko a ngā HRV/ERV i ngā rautaki DCV. Ka whakarerekētia ngā tere hauhautanga (ā, nō reira, te whakaora pūngao) *anake* i ngā wāhi me ngā wā e hiahiatia ana, i runga i te nohoanga i te wā tūturu (hei tauira, mā te whakamahi i ngā pūoko CO2, i te tūnga nohoanga PMS rānei), kia nui ake ai ngā penapena. He aha ai te whakahauhautanga i tētahi whare kanikani kau i te kaha katoa?

•Ngā Rauemi MatatauRangahau mō ngā rauemi matua whakawhiti wera he pai ake te whai hua, he ātete ki te poke, ā, he iti ake pea te utu.

•Tātari Whakapai AkeTe whakaurunga o ngā tātari whai huatanga teitei ake (e tata ana ki te HEPA) tae atu ki ngā hangarau hou pēnei i te ionization bipolar (me te whai whakaaro nui ki ngā hua taha) hei whakarei ake i te IAQ, inā koa i ngā wāhi morearea nui.

 

Ko te Kaupapa Matua: He Pūtea Atamai ki te Whai Hua me te Wheako

 

Kāore e taea te wareware i te rere o te pūngao mai i te hauhautanga kāore i te whakahaerehia mō ngā hōtēra e aro nui ana ki te utu me te manuhiri. He hangarau pakari, kua whakamātauhia ngā Hauhautanga Whakaora Wera me te Whakaora Pūngao e tuku ana i tētahi otinga whai hua. Ka hurihia e rātou te rerenga pūngao e tika ana hei whai wāhitanga mō te penapena nui, te whakapai ake i te whakamarie, te kounga hau pai rawa atu, me te whakahaere pumau ake.

 

Ahakoa me whai whakaaro ki te utu o mua, ko te tere o te whakahokinga mai me te maha o ngā painga ka waiho ngā pūnaha HRV/ERV ehara i te mea he kōwhiringa taiao anake, engari he whakataunga pakihi taketake mō ngā hōtēra e whai ana ki te arotau i ngā mahi, te whakapai ake i te wheako manuhiri, me te whakarite i te hua mō te wā roa.'e pā ana ki te whakahaere i te hau–me te pūngao e mau ana i a ia–te huri i tētahi pokapū utu huna hei puna whai huatanga me te makona o ngā manuhiri. I roto i te ao manaaki manuhiri whakataetae, koinā'He hau hou e tika ana kia haumi ki roto. Ina takiuru mai ngā manuhiri, e tumanako ana rātou ki te whakamarie; ka tukuna e ngā HRV/ERV he whakamarie, ka mahi puku i muri i ngā whakaaturanga kia pai ake ai te noho, kia hauora ake ai hoki te hua.
