Te āhua o nāianei o te karaihe mō ngā tatau, ngā matapihi me ngā pakitara ārai
Ina whakaritea ki ngā pakitara o waho o ngā whare, he nui te karāhe mārama e whakamahia ana e ngā tatau, ngā matapihi me ngā pakitara ārai, inā koa mō te maha o ngā whare hou kāore i te noho, kua tata te pūnaha pakitara ārai te hanganga tiaki o waho tino nui. Mō te pūnaha tatau, matapihi me te pakitara ārai, tata ki te 85% o te whānui o te pūnaha katoa te horahanga karāhe. Ka taea te kī he mahi penapena pūngao nui te karāhe mō te taupoki whare. I te mea he hanganga taupoki mārama o te whare, e rua ngā hapa nui o te pūnaha tatau, matapihi me te pakitara ārai kia tutuki ai te penapena pūngao whānui: ko tētahi ko te kore e taea te whakanui ake i te matotoru me te kore he rohe, ā, ko tētahi ko te kore e taea te iti rawa o te whakawhiti mārama;
Mai i te tirohanga o te penapena pūngao, te rama me te whakamarumaru he uaua ki te whai i te wā kotahi. E ai ki ngā tatauranga rangahau, ko ngā matapihi o waho (tae atu ki ngā matapihi tuanui) i roto i ngā hanganga tiaki whare te wāhanga matua o te whakapaunga pūngao, ā, neke atu i te 50% o te whakapaunga pūngao ka ngaro mā roto i ngā matapihi o waho. Nō reira, kua noho te pūnaha tatau, matapihi me te pakitara ārai hei āputa whakapaunga pūngao e uaua ana ki ngā whare ki te whakaoti. Ā, ko te āhuatanga o nāianei ko ngā otinga penapena pūngao e hangaia ana e mātou i roto i te pūnaha tatau, matapihi me te pakitara ārai e aro ana ki te whakaiti i te ngaronga pūngao o ngā kōtaha, ā, kāore i te maha ngā otinga kounga teitei hei whiriwhiri i roto i te kōwhiringa karāhe. Mō te karāhe whakamarumaru e whakamahia whānuitia ana, i runga i te whakaaro ki te karāhe Low-E, ka taea e te tauwehenga whakawhiti wera o te karāhe whakamarumaru te eke ki te 1.8W/(m2.K). Ko ngā whakaritenga tauwehenga wera (he iti iho i te 1.0W/(m2.K)) me whai paerewa teitei ake mō ngā kōtaha tatau me te matapihi. Ko te tikanga, kāore mātou i mutu te rapu otinga karāhe -karāhe korehaukua waiho hei whiringa pai rawa atu mō te hanga tatau, matapihi me ngā pakitara ārai hei whakatutuki i te tino whai hua me te penapena pūngao.
Ngā Take hei Kōwhiri i te Karāhe Korehau
He momo karāhe penapena hiko hou te karāhe korehau. He rerekē i te karāhe ārai tuku iho, ko te kaupapa o te karāhe korehau he kapu ārai korehau. Ka hiritia ngā karāhe e rua ki te taha, ka whakakorea ki te korehau, ka hangaia he paparanga korehau 0.2mm te matotoru.
Nā te korenga o te hau, ka wehea paitia e te karāhe korehau te kawe wera me te kawe wera, me te aukati pai i te hihi wera e te karāhe Low-E, ko te tauwehenga whakawhiti wera o te karāhe korehau anake ka taea te iti ki te 0.5 W/(m2.K), ahakoa he iti iho i te karāhe ārai me ngā karāhe e toru me ngā kōhao e rua. Ka taea e te taumata whakamarumaru wera o te karāhe korehau te whakatutuki i te mahi wera rite ki te mahi whakamarumaru wera o ngā pakitara whakamarumaru, e tino whakaiti ana i te pēhanga whakamarumaru wera o ngā kōtaha tatau, matapihi me ngā pakitara ārai. E ai ki te tirotiro tuturu a te National Construction Engineering Quality Supervision and Inspection Center, ka whakamahia ngā matapihi karāhe korehau i ngā wāhi makariri pēnei i a Beijing, ā, ka taea e te penapena pūngao i te takurua te neke atu i te 50%. Nō reira, ahakoa he matapihi karāhe, he pakitara ārai karāhe rānei, kāore te taupoki tuku mārama e rite ana ki te papa poto o te penapena pūngao o te whare, ā, ka taea te whakaiti i te whakapaunga pūngao o te whare katoa, ka eke ki ngā whāinga kua tohua mō ngā whare whakapaunga pūngao tino iti.
Wehewehenga Haruru:
Ko te taumaha o te karāhe korehau anake. Neke atu i te 37dB te ārai oro, ā, ka taea e te karāhe korehau whakakotahi te eke ki runga ake i te 42dB. Mā te whakamahi i ngā matapihi karāhe korehau, i ngā pakitara ārai rānei, ka taea te wehe i te haruru o waho me te whakapai ake i te taiao oro o roto.
Hei hua karāhe hou, he uaua ki te whakakapi i ngā painga o te karāhe korehau:
Ārai-Whakapūtanga:
Mā te kaha o te karāhe korehau e ārai i te wera nui, ka taea te wehe i te pāmahana o roto, o waho hoki, ā, ko te ātete-hauota he >75. Ahakoa i te takurua makariri o waho i te -20℃, kāore te rerekētanga pāmahana i waenga i te pāmahana mata o roto o te karāhe me te hau o roto e neke ake i te 5℃, he nui ake tēnei i te pāmahana hauota tomairangi.
He Whakamarie Ake:
He ngāwari te pupuri i te pāmahana me te haumākū pumau o te karāhe korehau i roto i te rūma nā te kaha o te whakamahana wera nui. Ko te rerekētanga i waenga i te pāmahana o roto o te karāhe me te pāmahana o te rūma he iti iho i te 3~5℃, ka whakakorea te makariri me te wera nui, ka whakaitihia te pikinga pāmahana i mua i te matapihi, ā, ka whakapai ake i te whakamarie o te taiao o roto.
Hei hua hou mō te karāhe tatau, matapihi me te pakitara ārai,karāhe korehauka taea te hipa me te whakakapi i te karāhe ārai noa i roto i te nuinga o ngā āhuatanga. I raro i te papamuri o ngā whakaritenga pakari ake a te whenua mō te tiaki pūngao o ngā whare, me te whai haere tonu o te iwi i te whakamarie o te taiao noho, ka arohia, ka whakaaetia hoki te mahi pai o te karāhe korehau e te tini o te tangata, ā, ka waiho hei whiringa karāhe tatau me te matapihi matua a meake nei.
