Whakamahia te Taiao:
1. Me noho te pāmahana wai uru ki waenga i te 0 ℃ me te 40°C, me te whakarite kia kore te wai e mimiti i roto i te hua.Na te mea he iti iho i te 0°C, ka maroke te wai, kare e rere te wai;ki te teitei ake i te 40°C, ka puta mai he waehere hapa i roto i te punaha whakahaere (kei runga ake i te awhe o te pāmahana kitenga o te punaha) ka mutu te mahi a te punaha.
2. Ki te hiahia koe ki te whakatakoto i te ipu wera o waho ki raro i te -30°C, e taunaki ana kia taapirihia he paparanga whakamarumaru, he uhi whakamaarama, he whakamaarama remu, tae noa ki te whakamaarama paipa i te wa e hoko ana.
Mō te Tiakitanga o te Pūnaha Tupa wera o waho ki te Taiao Pawera iti:
Ahakoa he punaha a-whare, he punaha kawemai ranei, kua whakaritea te mahi tiaki pāmahana iti ki roto i te punaha.Ina he nui te wai me te hiko o te hiko, ina he iti te pāmahana ki tetahi taumata (ko te punaha o te kaainga kei te 5-6 ° C, me te punaha kawemai he 7 ° C), ka puta te iti o te pāmahana. mahi tiaki o te punaha, katahi ka tukuna e te punaha te whakamahana kia tae ra ano te whakamahana ki te 10 ℃, ka mutu te whakamahana.
Whakaritenga Kaiwhakamahi:
1. Ko te wa ki te whakauru i te tapu wera o waho e taunaki ana kia whakauruhia me te hiko i te mutunga o te puna, i te timatanga o te ngahuru ranei, ara, i mua i te ekenga o te mahana ki te 0°C.
2. Ki te hiahia koe ki te whakamahi i te takurua, kia nui te wai i roto i te tubkia mau tonu te hiko kia kore ai e makariri.
3. Ki te kore koe e pai ki te whakamahi i te takurua, ko nga wai katoa i roto i te tubme whakamakuku i mua, me te tirotiro mena he toenga wai kei roto i te papu wai, i te paipa ranei, wetewetehia te hononga uru wai ki mua o te papu wai, ka whakahaha kia whakaeto te wai i roto i te tub.
4. Mena ka hiahia koe ki te tuku i te wai ki roto i te puna wera o waho i te takurua (te pāmahana iti-kore ranei), me kaha ki te whakarite kia uru te wai ki roto.tāpue kore e whakatio i mua i te taapiri i te nui o te wai, katahi ka whakaweto i te hiko kia tere ai te whakamahi.
