Tūnga 7.A puna utaina rawhi te ki rawhi te tauira ki te mau api mata.
8.The wai supply kawe ki te taata tei mau tauira hanga e kore e te pāmahana mōrahi nui 35 ℃ i te putanga i te taata tei mau tauira.
Kei 9.The taata tei tauira whakaminenga te i 90 ± 2 ° ki te mata o te paewhiri radiation me i pērā i ara e nga kanohi o te runga me kaiarahi raro o te tei mau tauira kei roto i te manureva taua rite te mata roto o te karapotia ki te rōpū radiation.
Apa 10.The teitei o te taata tei mau tauira te ki tukua ki te kia akina iho te reira whakapae, atu i te mata o te paewhiri radiation i waenganui i ngā whakamātautau, i te tūnga whakamātautau ki te tūranga tūtatari me te tumuaki-hurihia.
11.The pairati pūwera ko ngā o te ngongo maitai.
12.The hau me te supply rangi rārangi ki te rōpū radiation i roto i rere mita, tauwehe pēhanga, vaolo mana me ngā pūrere haumaru.
13.Heat Flux Mita: Range: 0 ~ 50 Kw / m2; Mata emissivity: ɛ = 0,95 ± 0.05.
14.Dummy whakatika poari ki tokotaha ma'u, tukuoro te wera rere mita, me te whakapuru.
Hua Taipitopito o te Mata Horahanga Auahi T hākawa
Ko te pūrere whakatö whakamātautau mata mura ko te BS 6853 raupapa nui-tere maitai mura retardant hei whakamatau, i te mea e tika ana mō ngā rauemi hanga Ingarangi, me te nui-tere maitai mura paerewa retardant whakamātautau. Ko te paerewa he BS 476-7. Whakamahia te tikanga whakamātautau te ki te whakatau i te toronga lateral o te mata tauira, ka hāngai i runga i te tere. Na whakatau te roa toronga te taumata tahunga. BS 476-7 Kei te matua whakamahia ki te ine i te toronga mura o papa kitea i runga i te taiepa, me tuanui.
Ko te tikanga whakamātautau ko ki te ine i te rere marama tino na roto i te arero te tauira ki te mura iti mā te pato i te huringa āta o te pūngao wera marama. Ko te mehua röpü marama wera 850mm X 850mm. Ko te matao o ka rite rawa ki te pereti whakatika pūwatawata wai me te waiariki marama koripi pūoko ki Whakatikaina te ānau maama rere waiariki taata tei mau i te whakamātautau tauira. He te taputapu whakamātautau whakaritenga tiketike i runga i te pae taiwhanga, me me te kaiwhakamahi ake mehua haumaru i mua i taea te mea whakamātautau kia huihui.
