Mā te mīhini pēhi waipēhi pou-whā ka tukuna te hinu waipēhi ki te poraka takirere i raro i te mahi a te papu hinu. Mā te pūnaha whakahaere e whakahaere ia takirere kia tae atu te hinu waipēhi pēhanga teitei ki ngā rūma o runga me raro o te rango waipēhi, ka neke te mīhini pēhi waipēhi. He taputapu te mīhini pēhi waipēhi e whakamahi ana i te wai hei tuku pēhanga.
He mea tino nui te hinu waipēhi mō ngā mīhini perehi pou-whā, ā, ko tētahi o ngā mahi nui hei whakaiti i te pakaru o te mīhini. Ko te whiriwhiri i te hinu waipēhi tika e pā tika ana ki te roa o te mahi a te mīhini waipēhi.
I te wā e whiriwhiri ana i te hinu mō te mīhini pēhi waipēhi pou-whā, me whiriwhiri tuatahi koe i te matotoru e tika ana. Me whai whakaaro te whiriwhiringa o te matotoru o te hinu ki ngā āhuatanga hanganga, te pāmahana mahi me te pēhanga mahi o te pūnaha waipēhi. I roto i te pūnaha tuku waipēhi, ko te papu hinu tētahi o ngā wāhanga tino tairongo ki ngā huringa o te matotoru o te hinu waipēhi. He matotoru iti me te matotoru mōrahi e whakaaetia ana mō ia momo papu. Hei whakaiti i te whakapaunga hiko, me whakamahi te hinu matotoru iti i te nuinga o te wā. Heoi, hei whakahinuhinu i ngā wāhanga matua me te ārai i te turuturu, me whiriwhiri te hinu waipēhi matotoru e tika ana.

1. Whakarōpūtanga Tauira Hinu Waipēhi
E toru ngā momo hinu waipēhi e whakarōpūtia ana kia rite ki ngā paerewa ā-motu: momo HL, momo HM, me te momo HG.
(1) Ko te hinu waipēhi momo HL he mea hanga mai i te hinu turanga reo kua oti te whakapai, he hohonu te hohonu, me ngā tāpiringa ārai-waikura me te ārai-waikura. E ai ki te nekehanga i te 40 nekehanga Celsius, ka taea te wehewehe i te matotoru ki ngā taumata e ono: 15, 22, 32, 46, 68, me te 100.
(2) Kei roto i ngā momo HM ko te konutea teitei, te konutea iti te konutea, te konutea teitei koretake me te momo kore pungarehu. E ai ki te nekehanga i te 40 nekehanga Celsius, ka wehea te matotoru ki ngā taumata e whā: 22, 32, 46, me te 68.
(3) He āhuatanga ārai-waikura me te ārai-waikura te momo HG. Hei tāpiri, ka tāpirihia he whakapai ake i te taupū matotoru, he pai ngā āhuatanga matotoru-mahana.
2. Te Whakamahinga o te Tauira Hinu Waipēhi
(1) Ka whakamahia te hinu waipēhi HL hei whakahinuhinu i roto i ngā pouaka whāriki me ngā pūnaha tohanga pēhanga-iti o ngā taputapu mīhini maha, ina kore he whakaritenga motuhake mō te hinu, ā, kei runga ake i te kore nekehanga Celsius te pāmahana o te taiao. He tino pai te urutau o ēnei hua ki te hiri, ā, ka taea e te pāmahana whakahaere mōrahi te eke ki te 80 nekehanga Celsius.
(2) Ko te hinu waipēhi HM te nuinga o te wā e whakamahia ana i roto i ngā pūnaha waipēhi o ngā papu vane taumaha, pēhanga-waenga me te pēhanga-teitei, ngā papu plunger me ngā papu taputapu. Hei tāpiri, he pai hoki tēnei momo hinu waipēhi mō ngā taputapu hangarau pēhanga-waenga me te pēhanga-teitei me ngā pūnaha waipēhi waka.
(3) He pai ngā āhuatanga ārai-waikura, ārai-waikura, ārai-kākahu, me te ārai-piri-paheke o te hinu waipēhi HG, nō reira he pai mō ngā pūnaha whakahinuhinu e whakamahi ana i ngā waipēhi taputapu mīhini me ngā ara ārahi.
Ko ngā pāmahana whakahaere o ngā hinu waipēhi o ngā taumata matotoru rerekē i raro i ngā whakaritenga rerekē koia ēnei.
| Ngā centistokes o te taumata matotoru (40℃) | Ko te matotoru e hiahiatia ana i te tīmatanga he 860 henetitoke | Ko te matotoru e hiahiatia ana i te tīmatanga he 110 henetitoke | Ko te matotoru mōrahi e hiahiatia ana i te wā e mahi ana ko te 54 henetisoke | Ko te matotoru mōrahi e hiahiatia ana i te wā e mahi ana ko te 13 henetitokē |
| 32 | -12℃ | 6℃ | 27℃ | 62℃ |
| 46 | -6℃ | 12℃ | 34℃ | 71℃ |
| 68 | 0℃ | 19℃ | 42℃ | 81℃ |
He maha ngā momo hinu waipēhi kei te mākete, ā, he maha anō hoki ngā momo mīhini waipēhi. Ahakoa he rite tonu ngā mahi a te hinu waipēhi, me whiriwhiri tonu ngā hinu waipēhi rerekē mō ngā mīhini waipēhi rerekē. I te wā e whiriwhiri ana i te hinu waipēhi, me mārama te kaimahi ki te mea e tonoa ana kia mahia, kātahi ka whiriwhiri i te hinu waipēhi tika mō te mīhini waipēhi.
Me pēhea te whiriwhiri i te hinu waipēhi tika mō te mīhini perehi waipēhi
E rua ngā tikanga e whakamahia ana i te wā e whiriwhiri ana i te hinu waipēhi. Ko tētahi ko te whiriwhiri i te hinu waipēhi kia rite ki ngā momo hinu me ngā whakaritenga kua tūtohutia e ngā tauira, ngā tohutohu rānei a te kaihanga mīhini waipēhi. Ko tētahi ko te whakaaroaro whānui i te whiriwhiringa o te hinu waipēhi i runga i ngā āhuatanga motuhake o te mīhini waipēhi, pērā i te pēhanga mahi, te pāmahana mahi, te tere nekehanga, te momo wāhanga waipēhi me ētahi atu āhuatanga.
I te wā e whiriwhiri ana, ko ngā mahi matua hei mahi ko: te whakatau i te awhe matotoru o te hinu waipēhi, te whiriwhiri i te momo hinu waipēhi e tika ana, me te whakatutuki i ngā hiahia motuhake o te pūnaha waipēhi.
I te nuinga o te wā ka tīpakohia i runga i ngā āhuatanga e whai ake nei:
(1) E ai ki ngā momo whiringa o ngā mīhini mahi pēhi waipēhi
He rerekē ngā whakaritenga matotoru o ngā mīhini tika me ngā mīhini whānui. Hei karo i te rerekētanga o ngā wāhanga mīhini i puta mai i te pikinga o te pāmahana, me te pā ki te tika o te mahi, me whakamahi e ngā mīhini tika te hinu waipēhi he iti ake te matotoru.
(2) Kōwhiria kia rite ki te momo papu waipēhi
He wāhanga nui te papu waipēhi o te mīhini pēhi waipēhi. I roto i te mīhini pēhi waipēhi, he tere te nekehanga, te pēhanga me te pikinga pāmahana, ā, he roa te wā mahi, nō reira he tino pakari ake ngā whakaritenga mō te matotoru. Nō reira me whai whakaaro ki te papu waipēhi i te wā e whiriwhiri ana i te matotoru.
(3) Kōwhiria kia rite ki te pēhanga mahi o te mīhini pēhi waipēhi
Ina teitei te pēhanga, me whakamahi te hinu matotoru teitei hei karo i te turuturu nui o te pūnaha me te iti o te whai huatanga. Ina iti te pēhanga mahi, he pai ake te whakamahi i te hinu matotoru iti, ka taea te whakaiti i te ngaronga pēhanga.
(4) Whakaarohia te pāmahana o te taiao mahi o te mīhini pēhi waipēhi
Ka rerekē te matotoru o te hinu kohuke nā te pānga o te pāmahana. Hei whakarite i te matotoru e tika ana i te pāmahana mahi, me whai whakaaro anō hoki ki te pānga o te pāmahana huri noa.
(5) Whakaarohia te tere o te nekehanga o ngā wāhanga mahi o te mīhini perehi waipēhi
Ina tino tere te neke o ngā wāhanga mahi i roto i te pūnaha waipēhi, ka iti hoki te tere rere o te hinu, ka piki haere te mate waipēhi, ā, ka iti haere te turuturu, nō reira he pai ake te whakamahi i te hinu matotoru iti.
(6) Kōwhiria te momo hinu waipēhi e tika ana
Mā te whiriwhiri i te hinu waipēhi mai i ngā kaihanga noa ka taea te whakaiti i temīhini pēhi waipēhingā hapa, ā, ka roa ake te ora o te mīhini pēhi.
