Pūnaha Tohatoha Pūngao Ā-Wharewha mō te Whakamahana Wai
E mōhiotia whānuitia ana te pūngao waiariki hei pūtake pūngao ma i ahu mai i te wera tūturu o te whenua. Ko ngā kōrero mō te pūngao waiariki e aro nui ana ki te whakaputa hiko nui. Heoi, ko tētahi o ngā tono tino whai hua me te ngāwari ko te whakamahana wai, i roto i ngā kāinga, i ngā hōtēra, i ngā hōhipera, i te umanga kai, tae atu ki ngā whare hākinakina. Ko te kī ki te whakamahinga angitu ehara i te mea kei roto i te pūtake wera anake, engari kei roto hoki i te pūnaha tohatoha pūngao waiariki—te raupapa o ngā tukanga e hopu ana, e whakawhiti ana, e rongoa ana, e tohatoha ana hoki i te wera kia pai ai te whakamahana o te wai, kia pumau, kia whai hua ai te pūngao.
Ariā Taketake o te Whakamahana Wai Geothermal
Ka mahi ngā whakamahana wai wera mā te whakamahi i te rerekētanga pāmahana i waenga i te pūtake wera me te wai e whakamahanatia ana. Ko ngā pūtake wera he puna wai wera nui (mō te whakaputa hiko) he puna pāmahana iti ki te waenga rānei pērā i ngā puna wera taiao, ngā puna pāpaku, te wai whenua rānei e whakamahia ana mā te papu wera. Mō ngā hiahia whakamahana wai, he pai ake ngā pūnaha pāmahana iti ki te waenga, nā te mea ko te pāmahana wai wera kei waenga i te 40–60°C mō te whakamahinga kāinga, ā, ka teitei ake pea mō ētahi tukanga ahumahi.
Mō te tohatoha, me kaha te pūnaha ki te pupuri i te pāmahana o te wai wera kia rite ki ngā whakaritenga i te wā e whakamahia ana, me whakaiti i te ngaronga wera i roto i ngā paipa, me te whakarato i te rere e tika ana i ngā wā pīki.
Ngā Wāhanga Matua o te Pūnaha Tohatoha
Ko te pūnaha tohatoha pūngao waiariki mō te whakamahana wai he maha ngā wāhanga matua:
1. Ngā pūtake wera whenua
He wai wera/korohū pea, he wai whenua, he pūngao wera rānei. Ko te whiriwhiri i te pūtake e whakatau ana i te hoahoa, ngā rauemi, me te rautaki whakahaere.
2. Ngā puna whakaputa me ngā puna weronga (mō ngā pūnaha waiariki)
Ka tangohia te wai wera mai i te puna whakaputa, kātahi ka whakahokia ki te puna wai mā te puna weronga hei pupuri i te pumau o te puna me te whakaiti i te pānga ki te taiao.
3. Whakawhiti wera
Ka whakawhitihia e tēnei wāhanga te wera mai i te wai wera whenua ki te wai ma hei whakamahi. Ka wehea e te whakawhiti wera te wai wera whenua, kei roto pea he kohuke, he waikura rānei, mai i te wai e whakamahia ana, kia haumaru ake ai, kia akuaku ake ai hoki te pūnaha.
4. Papu tohanga me te pūnaha paipa
Mā ngā papu ka mau tonu te rere o te wai wera me tōna tohatoha ki ngā wāhi rerekē. Kua hangaia ngā paipa hei whakaiti i te ngaronga o te wera me te pupuri i te pēhanga.
5. Tāke rokiroki (te rokiroki wera)
He ārai kawenga te tāke wai wera: e penapena ana i te wera ina iti te hiahia, e tuku ana hoki ina nui te hiahia. Ka whakanui ake tēnei i te whai huatanga, ā, ka whakaitihia te nui o te mahi i runga i te papu/whakawhiti wera.
6. Ngā pūnaha whakahaere me te haumaru
He mea nui ngā pāmahana, ngā takirere whakahaere, ngā pūoko pāmahana/pēhanga, ngā takirere whakaora, me ngā pūnaha aroturuki kounga wai mō te mahi pumau me te haumaru.
Hanganga Tohatoha: Pokapū, Pokapū rānei
E rua ngā huarahi matua i roto i ngā pūnaha tohatoha:
1) Pūnaha Pokapū
I roto i tēnei pūnaha, ka tukatukahia te wera whenua i te wāhi kotahi (hei tauira, he rūma miihini), kātahi ka tohatohahia te wai wera mā roto i tētahi whatunga paipa ki ngā momo kaiwhakamahi. He pai tēnei tauira mō:
- Rohe rōpū,
– Ngā hōtera me ngā whare noho,
- Hōhipera,
– Te rohe ahumahi, te puni rānei.
Ko ngā painga ko te tiaki arotahi ake, te whai huatanga o te tauine, me te whakahaere pāmahana ōrite ake. Ko ngā wero ko te haumi ki ngā paipa me te ngaronga wera pea mena he roa te tawhiti tohatoha.
2) Pūnaha Whakakore-pokapū
Ka whakanohoia ngā waeine whakamahana ki te taha o te wāhi e whakamahia ana, hei tauira, he pūnaha motuhake tō ia whare, tō ia poraka rānei e whakamahi tonu ana i te pūtake wera kotahi, e whakamahi ana rānei i te papu wera ā-rohe. Ko ngā painga ko te poto ake o ngā paipa tohatoha, te iti ake o te ngaronga wera, me te ngāwari ake. Ko ngā ngoikoretanga ko te maha atu o ngā wāhi tiaki me te hiahia kia ōrite te paerewa whakahaere hei pupuri i te mahi tino pai katoa.
Ngā Rautaki Tohatoha Wera: Tika, Ā-kore, me te Papu Wera
Mai i te taha o te tikanga whakawhiti wera, he maha ngā momo whirihoranga:
Tohatoha Tika (Whakamahinga Tika)
Mena he ma te wai wera whenua, ā, kāore e waikura, ka taea te whakamahi tika i te wera mō te whakamahana wai. Heoi, he onge te tūtohutanga mō tēnei mea mō te wai kāinga nā te mea he tūponotanga kei poke, kei mimiti, kei waikura hoki.
Te Tohatoha Ā-kore (Te Whakamahinga Ā-kore)
Ko te whirihoranga tino noa: ka rere te wai wera whenua mā roto i te whakawhiti wera, ka whakamahana i te porowhita wai māori. He haumaru ake tēnei pūnaha, he māmā ake te tiaki, ā, ka roa ake te ora o ngā taputapu.
Pūnaha Wera Whenua me te Papu Wera (Papu Wera Pūtake Whenua)
I ngā wāhi kāore he puna wera tūturu, ka taea te whakamahi i te wera whenua mā te porowhita whenua (whakapae, poutū rānei). Ka "whakaara" te papu wera i te pāmahana ki te taumata e hiahiatia ana mō te whakamahana wai. Kātahi ka whakahaerehia te tohatoha wera pērā i te pūnaha wai wera tikanga, me te tino whai hua (he maha ngā wā ka neke atu i te 3 te COP), inā koa me te hoahoa me te whakahaere porowhita tika.
Te Hoahoa Whatunga Paipa me te Ārai i te Ngaronga Wera
He tino whakawhirinaki te pai o te tohatoha ki te hoahoa o ngā paipa. Ētahi mātāpono nui:
– Te whakamarumaru o ngā paipa: ka whakaitihia te ngaronga wera e ngā rauemi whakamarumaru wera, inā koa i ngā rārangi roa, i ngā wāhi tuwhera rānei.
– Te whānui tika o te paipa: ki te iti rawa ka nui ake te ngaronga pēhanga me te kawenga papu, ki te nui rawa ka nui ake ngā utu me te nui o te wai me whakamahana.
– Porowhita hurihanga anō: I roto i ngā whare nunui, ka ārai te hurihanga anō i te rere o te wai matao mō te wā roa i mua i te taenga o te wai wera ki te pūwero. Heoi anō, me whakahaere te hurihanga anō kia kore ai e moumou pūngao.
– Te whakahaere i te pāmahana i te wā e whakamahia ana: ka pupuri te takirere whakaranu i te pāmahana haumaru hei ārai i te werawera, me te tuku hoki i te rokiroki i ngā pāmahana teitei ake mō te whai huatanga me te akuaku.
Ngā Wero Hangarau: Te Waikura, te Tauine, me te Kounga Wai
Kei roto i ngā wai werawera ngā kohuke rewa (te silica, te calcium carbonate) me ngā hau (CO₂, H₂S) ka puta ai ēnei:
– Te tauine i runga i ngā paipa me ngā whakawhiti wera, ka whakaiti i te whai huatanga o te whakawhiti wera,
– Te waikura o ētahi rauemi,
– Te hekenga o te nama me te pikinga o ngā utu tiaki.
Nō reira, ko ngā pūnaha tohatoha te tikanga e whakatinana ana i:
– Te kōwhiringa o ngā rauemi ātete-waikura (ētahi maitai kore waikura, te titanium mō ngā āhuatanga tino kino, ngā koranu motuhake rānei),
– He hoahoa whakawhiti wera ngāwari ki te horoi,
– Te maimoatanga matū (mēnā e tika ana) me te aroturukitanga ā-wā,
– Kaupapa werohanga anō i te wai hei pupuri i te pēhanga o te puna wai me te whakaiti i te rerenga ki te mata.
Te Whai Hua o te Pūngao me te Pono o te Whakahaere
Ko te painga o te pūngao waiariki ko tōna wātea pumau puta noa i te tau. Heoi anō, me whakapai tonu te whai huatanga mā te:
– Te whakahaere i te kawenga tihi me ngā tāke rokiroki,
– Mana whakahaere papu e hangai ana ki te inverter (VFD) kia rite ai te tere rere ki ngā whakaritenga,
– Te tuhi i ngā raraunga whakahaere (te pāmahana tomo/putanga, te rere, te pēhanga) hei kimi wawe i te hekenga o te mahi,
– Te whakamahere i te tiaki i te whakawhiti wera me te tātari.
Ka taea e tētahi pūnaha kua hoahoa pai te whakarato i te wai wera pumau i ngā utu whakahaere iti iho i ngā whakamahana hiko ātete, i ngā poiha wahie pūmua rānei, inā koa mō te wā roa.
Ngā Āhuatanga Taiao me te Haumaru
Mā te whakamahi i te pūngao waiariki mō te whakamahana wai ka taea te whakaiti i ngā tukunga CO₂ mā te whakakapi i te tahunga tika. Heoi anō, me whai whakaaro tonu ki ngā āwangawanga haumaru me te taiao:
– Kia kaua e whakaranua te wai wera ki te wai inu,
– Whakamahia anō te werohanga hei whakaiti i te pānga ki te mata,
– Whakaratohia he takirere haumaru pēhanga me te tiaki pāmahana,
– Kia tutuki i ngā paerewa kounga wai me ngā paerewa tāutanga paipa.
Te Katinga
He otinga whai hua, whai hua hoki ngā pūnaha tohatoha pūngao waiariki mō te whakamahana wai, ka taea te whakatinana i ngā tauine rerekē, mai i ngā whare noho ki ngā whanaketanga whakauru. Ko te angitu o te pūnaha ka whakatauhia nuitia e te hoahoa tohatoha: te whiriwhiri i te whirihoranga (pokapū, pokapū rānei), te whakamahi i te whakawhiti wera tika, te hoahoa i ngā paipa pai te whakamahana, te whakahaere i te tohatoha anō, me te whakahaere i ngā take tauine me te waikura. Mā te whakamahere tupato, ka taea e te pūngao waiariki te noho hei pou tuara mō tētahi pūnaha whakamahana wai iti-tukunga pono, utu-whai hua, me te pumau.
Ki te hiahia koe, ka taea e au te whakarerekē i tēnei tuhinga hei putanga hangarau ake (me ngā tūtohi rere, ngā tātaitanga wera māmā, ngā taunakitanga rauemi paipa rānei mō ngā āhuatanga wai motuhake) me tētahi putanga rongonui ake rānei mō te kaipānui whānui.
