Karāhe me te Hangarau Whakahaere Rā mō te Whai Hua Pūngao
I waenganui i te pikinga ake o ngā hiahia pūngao me ngā tono mō te whanaketanga tauwhiro, kei te werohia ngā whare hou kia pai ake te whakamahi pūngao me te kore e whakaiti i te whakamarie o te hunga noho. Ko tētahi wāhanga e tino pā ana ki te whakamahinga pūngao o tētahi whare ko te karāhe, inā koa i ngā mata me ngā matapihi. Ehara i te mea he wāhanga ataahua noa iho te karāhe, he huarahi rānei hei tuku i te mārama taiao ki roto, engari kua whanake hei rauemi hangarau teitei e taea ai te "whakahaere" i te wera me te hihi o te rā. Ko te hangarau whakahaere hihi o te rā i roto i te karāhe he otinga nui mō te whakaiti i ngā kawenga whakamatao (AC), te pupuri i ngā pāmahana rūma whakamarie, me te whakapai ake i te pai o te whakamahinga pūngao whānui.
He aha te wāhi nui o te karāhe ki te whakapaunga pūngao o te whare?
Ko te karāhe te ara matua mō te whakawhiti pūngao i waenga i te roto me te waho o te whare. I ngā āhuarangi pārūrū pērā i a Indonesia, ka taea e te hihi o te rā e tomo ana mā te karāhe te whakanui ake i te pāmahana o roto. Nō reira, ka piki ake te whakamahinga o te hauhautanga, ka piki ake ngā pire hiko, ā, ka piki ake te tapuwae waro o te whare. I tetahi atu taha, ki te pōuri rawa te karāhe, ki te ārai rānei i te nui o te māramatanga, ka piki ake te hiahia mō te rama horihori, ka piki ake te whakapaunga pūngao.
Ko te wero matua ko te kimi i te taurite: te tuku i te nui o te māramatanga taiao hei whakarite i te wāhi kanapa, whakamarie hoki, me te whakaiti i te wera o te rā kia kore ai e taumaha rawa te pūnaha whakamatao. Koinei te wāhi e uru mai ai te hangarau karāhe e whakahaerehia ana e te rā.
Ngā Mātāpono Taketake o te Whakahaere i te Rā
Ko te kaha o te hihi o te rā e pā ana ki te karāhe, he mārama kitea me te hihi whero-whero (wera). He mea hanga te karāhe whakahaere-rā hei whakahaere i te nui o tēnei kaha e tukuna ana, e whakaatahia ana, e mimitihia ana rānei.
Ko ētahi o ngā tawhā nui e whakamahia ana hei aromatawai i te mahi o te karaihe ko:
1. Te Whakawhiti Mārama Kitea (VLT): te ōrau o te mārama kitea ka taea te tomo ki roto i te rūma. Ka teitei ake te VLT, ka mārama ake te rūma i te mārama taiao.
2. Te Tauwehenga Whakanui Wera o te Rā (SHGC): e tohu ana i te nui o te wera o te rā e tomo ana mā te karāhe. Ko te iti o te SHGC, ko te pai ake o te pupuri i te wera.
3. Uara-U (te tauwehenga whakawhiti wera rānei): e ine ana i te kaha o te karāhe ki te ātete i te whakawhiti wera nā ngā rerekētanga o te pāmahana o waho-o-roto, ehara i te mea ko te hihi o te rā anake. Ko te iti o te Uara-U, ko te pai ake o te whakamarumaru.
Ko te tikanga, ko te karāhe e whakahaeretia ana e te hihi o te rā e aro ana ki tētahi SHGC iti, me te pupuri tonu i te VLT kia teitei kia kore ai te rūma e pōuri.
Ngā Momo Hangarau Karāhe Whakahaere i te Rā
1. Karāhe Iti-E (Iti te Putanga)
He paninga angiangi tō te karāhe Low-E e whakaiti ana i te tukunga o te mata karāhe. Ka whakaatahia e tēnei paninga te hihi infrared, ka ārai i te whakawhiti ngāwari o te wera mai i te rā, mai i roto rānei i te rūma. I ngā āhuarangi pārūrū, ka taea te hanga i te karāhe Low-E hei ārai i te wera o waho me te tuku tonu i te mārama e kitea ana.
Kei te rongonui haere te hangarau Low-E nā te mea he pai te mahi e tukuna ana: ka noho mārama tonu te rūma, ka whakaitihia te wera, ā, ka piki ake te whakamarie.
2. Karāhe Whakaata
He paninga whakarewa tō te karāhe whakaata e whakaata ana i ētahi o ngā hihi o te rā. He maha ngā wā ka kitea tēnei pānga tirohanga i roto i ngā whare teitei, ka "kanapa" te āhua, ka rite rānei ki te whakaata. Ko ōna painga matua ko tōna kaha ki te whakaiti i te wera me te kanapa.
Heoi anō, me whakamahi te karāhe whakaata i runga i te horopaki: ka pā te whakaata nui ki te taiao e karapoti ana, hei tauira, ka nui ake te kanapa mō ngā kaiwhakamahi rori me ngā whare tata.
3. Karāhe Tae
Ka hangaia te karāhe tae mā te tāpiri tae ki te rauemi karāhe hei mimiti i te pūngao o te rā. Ka taea e ngā tae pēnei i te hina, te kakariki, te parahi rānei te whakaiti i te kaha o te mārama me te wera e tomo mai ana.
Ko te ngoikoretanga, he maha ngā wā ka whakaitihia te VLT e te tāpiri tae. Ko te tikanga ka pōuri haere te rūma, ā, ka hiahiatia he whakamārama i te awatea, ka whakaitihia ngā painga penapena pūngao mena kāore te hoahoa rama i arotauhia.
4. Karāhe Whakakirikiri me te Papanga Motuhake
E rua ngā paparanga karāhe o te karāhe whakakikoruatia, me te kiriata (paparanga-i-roto) i waenganui. Haunga te whakanui ake i te haumaru (he iti ake te pakaru o te karāhe), ka taea te hanga i te paparanga-i-roto kia kore ai e pāngia e te hihi UV me ētahi hihi infrared. Mā tēnei ka āwhina ki te tiaki i te roto mai i te memeha me te whakaiti i te kawenga wera.
5. Karāhe Whakamarumaru (Karāhe Takirua / IGU)
Ko te Wāhanga Karāhe Ārai (IGU) he mea hanga ki ngā whārangi karāhe e rua, neke atu rānei, e wehea ana e te āputa hau, hau rānei (hei tauira, te argon). He tino whai hua ngā IGU ki te whakaheke i te uara-U, ā, mā reira ka whakaitihia te whakawhiti wera nā ngā rerekētanga pāmahana.
Ina whakakotahihia ngā IGU ki te paninga Low-E, ki te karāhe whakahaere rā rānei, ka tino pai ake ngā hua: ka pupuri i te wera hihi me te whakanui ake i te whakamarumaru wera.
6. Karāhe Atamai
Mā ngā hangarau karāhe atamai pērā i te karāhe hiko-kōrohiko me te karāhe wera-kōrohiko ka taea e te karāhe te whakarerekē i tōna kanapa i runga i ngā āhuatanga. I te rā paki, ka taea e te karāhe te whakapōuri hei whakaiti i te wera me te kanapa; i ngā rā kapua, i te ahiahi rānei, ka mārama ake te karāhe kia uru mai ai te mārama taiao.
Ahakoa he utu nui tonu, ka oati te karāhe atamai he nui te penapena pūngao, inā koa i roto i ngā whare he whānui ngā mata karāhe me ngā aronga e whiwhi ana i te rā nui.
Pānga ki te Whai Huatanga Pūngao me te Whakamarie
Mā te whakamahi i te karāhe e whakahaerehia ana e te rā ka taea te whakaiti i ngā kawenga whakamatao. Ina whakaitihia te wera o te rā, ka iti ake te mahi a ngā hauhautanga, ka whakaitihia te whakapaunga pūngao. Hei tāpiri, mā te karāhe tika ka whakaitihia hoki ngā wāhi wera e tata ana ki ngā matapihi, ka hanga he tohatoha pāmahana ōrite ake, ā, ka whakapai ake i te whakamarie o te hunga noho.
Ētahi atu painga:
– Ka whakaiti i te kanapa kia pai ake ai te mahi tata ki ngā matapihi.
– Ka tiaki i ngā tāonga me ngā papa mai i ngā kino o te hihi UV.
– He mea whakaaroaro pinepine ngā kairihi me ngā kaipupuri moni ki te whakapiki i te uara o te whare nā te pai ake o te mahi pūngao.
Ngā Whakaaro Hoahoa me te Kōwhiringa Karāhe
Ehara i te mea ngāwari te whiriwhiri i te karāhe e whakahaerehia ana e te rā. He maha ngā mea hei whakaaroaro māu:
1. Te whakatakotoranga o te whare: Ko ngā taha rawhiti me te taha hauauru ka nui ake te wera e whiwhihia ana e te taha nā te iti o te koki o te rā. He tino whai hua te karāhe SHGC iti ki ēnei taha.
2. Ōwehenga matapihi ki te pakitara (WWR): me kaha ake ngā rautaki whakahaere wera mō ngā mata o mua he nui ngā karaihe.
3. Ngā whakaritenga mō te māramatanga taiao: Me whakarerekē te VLT kia mārama tonu ai te rūma, engari kaua e nui rawa ngā māramatanga.
4. Te whakakotahitanga me ngā taputapu whakamarumaru: ka taea te whakamahi tahi i ngā taupee, ngā ārai matapihi, ngā arai o waho, me ngā otaota me te karāhe hei whakaiti i te wera.
5. Te ataahua me te tūmataitinga: ka pā te taumata whakaata me te tae o te karāhe ki te āhua o te whare me te whakamarie tirohanga.
6. Ngā utu mō te huringa ora: tera pea he nui ake te utu i te tīmatanga mō te karāhe hangarau teitei, engari mā te penapena pūngao mō te wā roa ka taea te whakakore i ngā utu tāpiri.
Whakamutunga
He mea nui te karāhe me te hangarau e whakahaerehia ana e te rā i roto i te hoahoa whare e penapena ana i te pūngao, inā koa i ngā āhuarangi wera. Mā roto i ngā auahatanga maha pērā i te Low-E, te karāhe whakaata, ngā IGU, me te karāhe atamai, ka taea e ngā whare te whakaiti i te wera e riro mai ana me te kore e ngaro ngā painga o te māramatanga taiao. Ko te mutunga mai he wāhi whakamarie ake, he penapena pūngao nui, me te whai wāhi ki te whakaiti i ngā tukunga waro.
Ā tōna wā, mā te whakamahinga o te karāhe atamai me tōna whakaurunga ki ngā pūnaha whakahaere whare ka kaha ake te mahi a te karāhe hei "kiri" whare kaha. Mā te whiriwhiri karāhe tika me te hoahoa hoahoanga whānui, kāore te whai huatanga o te pūngao e noho hei whāinga noa iho, engari hei paerewa hou mō ngā whare hou.
