Me pēhea te whakanui ake i te whai huatanga o ngā pūnaha whakamatao waiariki
Ko ngā pūnaha whakamatao waiariki—e kiia ana ko te whakamatao pūtake whenua, he wāhanga rānei o te pūnaha papu wera waiariki (GSHP)—ka whakamahi i te pāmahana pumau o te whenua hei āwhina i te whakamatao i ngā whare. Ki te whakatauritea ki ngā pūnaha whakamatao tikanga e whakawhirinaki katoa ana ki te hau o waho e rerekē ana, ka taea e ngā huarahi waiariki te tuku i te iti o te whakapaunga pūngao, te whakamarie wera pumau ake, me te roa ake o te oranga o ngā taputapu. Heoi, kāore te whai huatanga o te pūnaha whakamatao waiariki i te teitei aunoa; he nui te awe o te kounga o tōna hoahoa, te tāutanga, te whakahaere, me te tiaki. Anei ngā mahi whai hua me ngā mahi rautaki hei whakapai ake i te whai huatanga o te pūnaha whakamatao waiariki.
1. Kia mārama ki te momo pūnaha me tōna whaitake ki te wāhi.
Ko te taahiraa tuatahi ki te whakapai ake i te whai huatanga ko te whakarite kia tika te momo pūnaha waiariki kua tīpakohia mō ngā āhuatanga o te papaanga me ngā whakaritenga kawenga whakamatao. He maha ngā whirihoranga e kitea whānuitia ana:
– Porowhita kati whakapae: ka tanumia ngā paipa ki te taha papaku, ki te taha roa hoki. He pai mō ngā wāhi nui, he iti te utu keri, engari he pāngia e ngā huringa ā-wā o te pāmahana o te mata o te oneone.
– Porowhita kati poutū: ka whakaurua te paipa ki roto i te puna kia hohonu ake. He pai mō te wāhi iti me te mahi pumau ake, engari he nui ake ngā utu keri.
– Porowhita kati i roto i te wai (porowhita roto/roto): e whakamahi ana i ngā wai. He whai hua mēnā e wātea ana, ā, e tutuki ana i ngā whakaritenga kounga taiao.
– Porowhita tuwhera: te tango i te wai whenua, kātahi ka tukuna. He tino whai hua pea tēnei, engari kei runga i ngā whakaaetanga, te kounga o te wai, me te mōrearea o te paru/waikura.
Mā te whiriwhiri i te whirihoranga tika ka taea te karo i tētahi pūnaha "ka nui rawa te mahi" ka uaua ai te mahi a te compressor i ngā wā katoa nā te mea kāore e tino pai te whakawhiti wera me te whenua.
2. Whakahaerehia ngā tataunga kawenga whakamatao tika
Ko te hapa tino kitea i roto i ngā pūnaha HVAC ko te rahi rawa, te iti rawa rānei. I roto i ngā pūnaha waiariki, ka nui ake te pānga nā te mea he hononga tata te rahi o te koropiko whenua me te kaha o te papu wera ki te kawenga. Hei whakapai ake i te whai huatanga:
– Whakamahia he tikanga tatau kawenga (hei tauira, te huarahi hangarau HVAC paerewa) e whai whakaaro ana ki te whakatakotoranga o te whare, te rauemi taupoki, te horahanga o te karaihe, te nohoanga, ngā taputapu, te hauhautanga, me te āhuarangi o te rohe.
– Whakaarohia ngā kawenga tino nui me ngā kawenga toharite o ia rā/o ia wā.
– Whakaarohia ngā rautaki whakaiti kawenga i te tuatahi (te whakamarumaru, te whakamarumaru, te karāhe iti-paheketanga, te whakahaere urunga). He iti ake te utu mō te whakaiti i ngā kawenga whakamatao i te whakanui ake i te kaha waiariki.
Ka roa ake te mahi a te pūnaha i hangaia mō ngā kawenga tuturu i ngā kawenga wāhanga, ā, he pai ake tēnei i te huringa poto.
3. Whakapai ake i te hoahoa whakawhiti wera porowhita whenua
Ko te mahi a te pūnaha waiariki whenua e whakawhirinaki ana ki te kaha o te porowhita ki te whakawhiti wera ki te whenua. Ko ngā mahi hei whakapai ake i te whai huatanga ko:
– Te roa me te hohonu o te koropiko e tika ana: ki te poto rawa te koropiko, ka tere te piki o te pāmahana wai i te wā e whakamatao ana, ka kaha ake te mahi a te pūwhakakoi.
– Te tawhiti tika i waenga i ngā paipa: mēnā he tata rawa ngā paipa tetahi ki tetahi, ka pāngia pea e te "pāwerawera" ā, ka heke te kaha o te oneone ki te mimiti i te wera.
– Rauemi paipa kounga teitei: Ko te HDPE te mea e whakamahia whānuitia ana nā te mea he ātete ki te waikura, ā, he roa te ora. Me ma ngā hononga whakarewa hei ārai i ngā turuturu.
– Te whakakī tika i ngā kōhao keri mō ngā koropiko poutū: mā te whakakī pai o te wai wera ka āwhina i te whakawhiti wera mai i te paipa ki te whenua. Ka taea e te whakakī ngoikore te hanga i ngā āputa hau ka aukati i te whakawhiti wera.
– Te whakamahinga o ngā raraunga matawhenua/waiwhenua: Ka pāngia te kawe wera e ngā āhuatanga o te uku, te onepu, te toka, me te wai whenua. Mā te rangahau pai ka āwhina i te karo i ngā hoahoa whānui kāore pea e tika.
Ko te hoahoa porowhita tino pai te tūāpapa o te whai huatanga; he uaua ki te "whakatika" i ngā hapa i tēnei wā mā te whakahaere, mā te tiaki rānei anake.
4. Whakamahia ngā papu wera tino whai hua me te whakahaere tika o te pēhi.
Kei ngā waeine papu wera whenua hou ngā kōwhiringa tere rerekē, maha-wāhanga rānei, ka taea te whakapai ake i te whai huatanga i ngā kawenga wāhanga. Ngā mea hei whakaaroaro:
– Kōwhiria he waeine he COP/EER teitei i ngā āhuatanga whakahaere e tika ana (te pāmahana tomo/putanga wai, te pāmahana wai mō te wai, me ētahi atu).
– Whakaarohia he pūwhakakoi hurihuri kia taea ai e te pūnaha te whakarerekē maeneene i te kaha, te whakaiti i te huringa me te pupuri i te pāmahana rūma pumau ake.
– Me whakarite kia ma, kia kore hoki e purua te whakawhiti wera o roto hei ārai i te piki haere o ngā rerekētanga pāmahana kāore e tika ana.
Ahakoa kua tapaina te waeine he tino whai hua, ko te hua whakamutunga e whakawhirinaki tonu ana ki te tāutanga tika me ngā tautuhinga whakahaere.
5. Whakanuia te whai huatanga o te taha tohatoha: ngā papu tohanga me ngā paipa/pūwero
Ehara i te mea ko te "mīhini" anake te painga o te pūnaha, engari ko te pūngao tāpiri hei neke i te wera me te wai.
– Whakamahia he papu tohanga me te ECM, he hangarau tere rerekē rānei i roto i te porowhita wai. Ka taea e ngā papu nui, tere pumau te whakapau i te hiko nui.
– Me whakarite kia whakamahanatia te paipa ina haere ana i roto i ngā wāhi wera, i ngā wāhi ratonga kore hauhautanga rānei, hei ārai i te pikinga o te wera ka whakanui ake i te kawenga whakamatao.
– Mō ngā pūnaha hau, arotauhia te hoahoa o ngā paipa hau: whakaitihia ngā turuturu, te iti o te pēhanga pūmau, me te taurite pai. Ka taea e ngā turuturu paipa hau i te tuanui/te tuanui te moumou pūngao, me te whakaiti i te kaha whai hua.
Ko te whakaiti i ngā ngaronga me ngā turuturu o te pehanga he huarahi tere ki te whakapiki i te pai o te mahi me te kore e whakarerekē i te pūnaha matua.
6. Whakatinanahia ngā rautaki whakahaere me te aunoatanga o te whare
Mā te whakahaere pai ka tino whakapai ake i te whai huatanga o ia rā:
– Tauritenga urutau: kaua e whakatakoto kia iti rawa. Mā te rerekētanga 1–2°C i roto i te tauritenga ka taea te penapena nui.
– Te whakarite i ngā hāora e whakamahia ana te rūma, me te whakaroa anō hoki ina kore e whakamahia.
– Te whakarōpūtanga rohe: te wehewehe i ngā rohe he rerekē ngā tauira whakamahinga kia kore ai e tino mātao rawa ngā rohe katoa.
– Te aro turuki i ngā pāmahana tomo/putanga o te koropiko me ngā tere rere o te wai hei kite i te hekenga o te mahi (hei tauira, te tīmatanga o te "whakamākūkū wera" o te koropiko, ngā raruraru papu rānei).
– Te whakaurunga ki ngā pūoko CO₂ hei whakahaere i te hau e whakahaerehia ana e te hiahia kia kore ai e nui rawa te kawenga huna/aronga mai i te hau o waho.
Ka tino whai hua te mahi a ngā pūnaha waiariki ina whakahaerehia tonutia, ā, kāore e akiakihia kia whai i ngā huringa ohorere o te pāmahana.
7. Te whakahaere i te haumākū o roto me te kounga o te hau
I ngā āhuarangi makuku, ko te kawenga huna (te ngaronga o te mamaoa wai) te nuinga o te wā ka nui ake. Ka piki ake te whai huatanga o te whakamatao mēnā ka whakahaerea tika te makuku:
– Me whakarite kia taea e te waeine te whakahaere i te whakamaroke me te kore e tino makariri te pāmahana o te rūma.
– Whakaarohia he pūnaha hau o waho (DOAS) he pūkaha whakaora pūngao rānei (ERV) hei whakaiti i te taumahatanga o te hau hou.
– Kia ma te tātari me te koiri kia kore ai e aukatia te rere o te hau, ka whakaiti i te kaha o te pā hau ki te tango i te makuku me te whakanui ake i tana whakapaunga hiko.
Mā te haumākū whakahaeretia ka paku teitei ake te pāmahana, me te kore e whakaiti i te whakamarie, ka nui ake te penapena pūngao.
8. Whakahaerehia te whakatūnga me te tiaki ā-wā
He maha ngā pūnaha whai hua i runga i te pepa kāore e tutuki i tā rātou mahi i whakaritea nā te mea kāore i whakamatautauria, i whakatikatikaina rānei i muri i te tāutanga. He mea nui te whakatūnga hei whakarite:
– Te tere rere o te porowhita e ai ki te hoahoa.
– Kei te mahi tika ngā takirere, ngā pūoko, ngā whakamahana me ngā arorau whakahaere.
– Kāore he hau e mau ana i roto i te koropiko (hau raka) e whakaiti ana i te whakawhiti wera.
– Kei roto i te awhe haumaru te pāmahana whakahaere mō te pūwhakakoi me te wai.
Ko ngā mahi tiaki auau ko te horoi i te tātari, te tirotiro i te papu me te pūwero, te tirotiro i te pēhanga/rere, me te whakamātautau i te kounga o te wai (hei tauira, te kukū o te ārai huka, mēnā e whakamahia ana). Mā te tiaki ārai ka ārai i te hekenga o te whai huatanga e kore e kitea tae noa ki te pikinga nui o ngā pire hiko.
9. Arotakehia te "taurite wera" me te mōrearea o te whakaemi wera
I ētahi whare, he nui ake te kawenga whakamatao i te kawenga whakamahana. Nō reira, ka "maumau" tonu te wera ki te whenua, ka mahana ake te whenua i ia tau, i ia tau, ka whakaiti i te whai huatanga (nā te mea ka piki ake te pāmahana o te porowhita i a ia e whakamatao ana). Ngā otinga pea hei whakaaroaro:
– Pūnaha ranu: te tāpiri i tētahi pourewa whakamatao, i tētahi pouaka whakamatao maroke rānei hei āwhina i te tango i te wera i ngā wā pīrahi.
– Te whakaora wera: whakamahia te wera para mō te whakamahana wai o te whare, mō ētahi atu tukanga rānei.
– He hoahoa porowhita e whai whakaaro ana ki te mahi maha-tau, kaua ki te wā kotahi anake.
Mā te pupuri i te taurite wera o te oneone ka āwhina i te pupuri i te whai huatanga mō te wā roa.
10. Whakamahia ngā raraunga mahi hei whakapai tonu
Hei whakamutunga, ka tutuki te whai huatanga pai rawa atu mā te ine:
– Tuhia motuhake te hiko e pau ana i te pūwero, te papu me te pā hau mēnā ka taea.
– Aroturukihia te COP "tūturu" mā te whakatairite i te pūngao hiko me te kaha whakamatao i whakaputaina.
– Tāutuhia ngā hāora mahi tino moumou, ka hono atu ki ngā āhuatanga o te rangi, te nohoanga, me ngā wā kua whakaritea.
– Me whakarerekē haere mārire ki ngā mana whakahaere, te rere o ngā mahi, me ngā wātaka.
Mā te huarahi e ahu mai ana i ngā raraunga, ka taea te whakapai ake i ngā pūnaha waiariki i roto i te wā, kaua e whakawhirinaki noa ki ngā whakaaro hoahoa tuatahi.
Te Katinga
Ko te whakapai ake i te whai huatanga o te pūnaha whakamatao waiariki me aro nui ki ēnei: mai i te whiriwhiri i te porowhita me ngā tatau kawenga tika ki te hoahoa whakawhiti wera whenua me te whiriwhiri papu wera, ki te whakahaere mahi me te tiaki. Mā te arotahi ki te whakaiti i te kawenga whakamatao, te hoahoa porowhita tika, ngā taputapu rerekē e penapena ana i te kaha, me te aroturuki i te mahi ka puta ngā hua tino nui. Mā ēnei rautaki, ehara i te mea ka penapena noa te pūnaha whakamatao waiariki engari ka pumau, ka whakamarie, ka pono hoki mō te wā roa.
