Kua wehea te whakahaere wera o te pūnaha hiko motuka ki te whakahaere wera o te pūnaha hiko waka wahie tuku iho me te whakahaere wera o te pūnaha hiko waka hiko hou. Inaianei kua tino pakari te whakahaere wera o te pūnaha hiko waka wahie tuku iho. Ka whakakahangia te waka wahie tuku iho e te miihini, nō reira ko te whakahaere wera miihini te arotahi o te whakahaere wera miihini tuku iho. Ko te whakahaere wera o te miihini ko te nuinga o te pūnaha whakamatao o te miihini. Neke atu i te 30% o te wera i roto i te pūnaha motuka me tuku e te ara iahiko whakamatao miihini hei ārai i te wera nui o te miihini i raro i te mahi taumaha. Ka whakamahia te whakamatao o te miihini hei whakamahana i te kāpini.
Ko te tipu hiko o ngā waka tuku iho he mea tito mai i ngā miihini me ngā tuku hiko o ngā waka tuku iho, ko ngā waka hiko hou he mea tito mai i ngā pākahiko, ngā motuka, me ngā mana hiko. Kua nui ngā panonitanga o ngā tikanga whakahaere wera o ēnei e rua. Ko te awhe pāmahana mahi noa o te pākahiko o ngā waka hiko hou ko te 25～40℃. Nō reira, ko te whakahaere wera o te pākahiko me pupuri kia mahana, me te whakamarara hoki. I te wa ano, kaua e tino teitei te pāmahana o te motuka. Mena he tino teitei te pāmahana o te motuka, ka pā ki te roa o te mahi a te motuka. Nō reira, me mahi hoki te motuka i ngā mahi whakamarara wera e tika ana i te wā e whakamahia ana. Ko te mea e whai ake nei he whakataki ki te pūnaha whakahaere wera o te pākahiko me te pūnaha whakahaere wera o te mana hiko o te motuka me ētahi atu wāhanga.
Pūnaha whakahaere wera pākahiko hiko
Ko te pūnaha whakahaere wera o te pākahiko hiko e wehea ana ki te whakamatao hau, te whakamatao wai, te whakamatao rauemi huringa ā-wāhanga me te whakamatao paipa wera i runga i ngā momo pāpāho whakamatao rerekē. He rerekē ngā mātāpono me ngā hanganga pūnaha o ngā momo tikanga whakamatao rerekē.
1) Te whakamatao hau o te pākahiko hiko: ka whakawhiti wera ā-pūhiko te pākahiko me te hau o waho mā te rere o te hau. Ko te whakamatao hau ka wehea whānuitia ki te whakamatao taiao me te whakamatao ā-pūhiko. Ko te whakamatao taiao ko te whakamatao i te pākahiko e te hau o waho i te wā e oma ana te motuka. Ko te whakamatao hau ā-pūhiko he tāuta i tētahi pā hau hei whakamatao ā-pūhiko ki te pākahiko. Ko ngā painga o te whakamatao hau he iti te utu me te ngāwari o te tono arumoni. Ko ngā ngoikoretanga ko te iti o te whai huatanga o te wera, te nui o te ōwehenga noho wāhi, me ngā raruraru haruru nui.Whakamahana Hau PTC)
2) Te whakamatao wai o te pākahiko hiko: ka tangohia te wera o te kete pākahiko e te rere o te wai. Nā te mea he nui ake te kaha wera motuhake o te wai i te hau, he pai ake te pānga whakamatao o te whakamatao wai i te whakamatao hau, ā, he tere ake te tere whakamatao i te whakamatao hau, ā, he ōrite te tohatoha pāmahana i muri i te mararatanga wera o te kete pākahiko. Nō reira, he whānuitia te whakamahinga o te whakamatao wai i te taha pakihi.Whakamahana Whakamatao PTC)
3) Te whakamatao i ngā rauemi huringa ā-wāhanga: Kei roto i ngā rauemi huringa ā-wāhanga (PhaseChangeMaterial, PCM) te paraffin, ngā tote waikura, ngā waikawa ngako, me ētahi atu, ka taea te mimiti, te tuku rānei i te nui o te wera huna ina puta he huringa ā-wāhanga, i te mea kāore anō kia rerekē te pāmahana. Nō reira, he nui te kaha rokiroki pūngao wera o te PCM me te kore e pau te pūngao tāpiri, ā, he whānuitia te whakamahinga i roto i te whakamatao pākahiko o ngā hua hiko pēnei i ngā waea pūkoro. Heoi, kei te rangahau tonu te whakamahinga o ngā pākahiko hiko motuka. He iti te kawe wera o ngā rauemi huringa ā-wāhanga, ka rewa te mata o te PCM e pā ana ki te pākahiko, i te mea kāore ētahi atu wāhanga e rewa, ka whakaiti i te mahi whakawhiti wera o te pūnaha, ā, kāore e pai mō ngā pākahiko hiko nui. Mena ka taea te whakatau i ēnei raruraru, ka noho te whakamatao PCM hei otinga whanaketanga tino pea mō te whakahaere wera o ngā waka hiko hou.
4) Whakamatao i ngā paipa wera: He taputapu te paipa wera e hangai ana ki te whakawhiti wera huringa āhua. He ipu hiri te paipa wera, he paipa hiri rānei kua whakakiia ki te reo/wai mahi kua mākū (wai, ethylene glycol, acetone rānei, me ētahi atu). Ko tētahi wāhanga o te paipa wera ko te pito mimiti, ā, ko tētahi atu pito ko te pito whakapūhaumāota. Kāore e taea e ia te mimiti noa i te wera o te kete pākahiko engari ka taea hoki te whakamahana i te kete pākahiko. Koinei te pūnaha whakahaere wera pākahiko hiko tino pai i tēnei wā. Heoi, kei te rangahau tonuhia.
5) Te whakamatao tika i roto i te hauhautanga: ko te whakamatao tika he huarahi ki te whakamahi i te kaupapa o te hauhautanga R134a me ētahi atu hauhautanga ki te mimiti me te mimiti i te wera, ā, ka tāutahia te whakamatao o te pūnaha hauhautanga ki roto i te pouaka pākahiko hei whakamatao tere i te pouaka pākahiko. He pai te whakamatao o te pūnaha whakamatao tika, ā, he nui te kaha whakamatao.
