1. Tirohanga whānui mō te whakahaere wera o te kokopiti (hauātanga waka)
Ko te pūnaha hauhautanga te mea nui ki te whakahaere i te wera o te motuka. E hiahia ana te taraiwa me ngā pāhihi ki te whai i te whakamarie o te motuka. Ko te mahi nui o te hauhautanga motuka ko te whakarite kia pai te taraiwa o te wāhi pāhihi mā te whakarerekē i te pāmahana, te haumākū me te tere o te hau i roto i te wāhi pāhihi o te motuka me te taiao eke. Ko te kaupapa matua o te hauhautanga motuka ko te whakamatao, te whakamahana rānei i te pāmahana i roto i te motuka mā te kaupapa wera-tinana o te mimiti wera mimiti me te tuku wera hauhautanga. Ina iti te pāmahana o waho, ka taea te tuku hau wera ki te kāpini kia kore ai te taraiwa me ngā pāhihi e mātao; ina teitei te pāmahana o waho, ka taea te tuku hau pāmahana iti ki te kāpini kia mātao ai te taraiwa me ngā pāhihi. Nō reira, he tino nui te mahi a te hauhautanga motuka ki te hauhautanga o te motuka me te whakamarie o ngā kainoho.
1.1 Pūnaha hauhautanga waka hiko hou me te mātāpono mahi
Nā te mea he rerekē ngā taputapu taraiwa o ngā waka hiko hou me ngā waka wahie tuku iho, ka peia te pūwero hauhautanga o ngā waka wahie e te miihini, ā, ka peia te pūwero hauhautanga o ngā waka hiko hou e te motuka, nō reira kāore e taea te peia te pūwero hauhautanga o ngā waka hiko hou e te miihini. Ka whakamahia he pūwero hiko hei pēhi i te hauhautanga. He rite tonu te kaupapa matua o ngā waka hiko hou ki tērā o ngā waka wahie tuku iho. Ka whakamahia te hauhautanga hei tuku i te wera me te mimiti hei mimiti i te wera hei whakamatao i te wāhi noho o ngā pāhihi. Ko te rerekētanga anake ko te whakawhiti i te pūwero ki te pūwero hiko. I tēnei wā, ko te pūwero panuku te nuinga o te wā e whakamahia ana hei pēhi i te hauhautanga.
1) Pūnaha whakamahana haurua-ārahi: Ka whakamahia te whakamahana haurua-ārahi mō te whakamatao me te whakamahana mā ngā huānga me ngā pito haurua-ārahi. I roto i tēnei pūnaha, ko te thermocouple te wāhanga matua mō te whakamatao me te whakamahana. Honoa kia rua ngā taputapu haurua-ārahi hei hanga i tētahi thermocouple, ā, i muri i te whakamahinga o te iahiko tika, ka puta he rerekētanga wera me te pāmahana i te atanga hei whakamahana i te roto o te kāpata. Ko te painga matua o te whakamahana haurua-ārahi ko te tere o te whakamahana i te kāpata. Ko te ngoikoretanga matua ko te nui o te hiko e pau ana i te whakamahana haurua-ārahi. Mō ngā waka hiko hou e hiahia ana ki te whai i ngā maero, he tino kino tōna ngoikoretanga. Nō reira, kāore e taea te whakatutuki i ngā whakaritenga o ngā waka hiko hou mō te penapena hiko o ngā hauhautanga. He mea nui ake hoki kia rangahau te tangata i ngā tikanga whakamahana haurua-ārahi me te hoahoa i tētahi tikanga whakamahana haurua-ārahi whai hua me te penapena hiko.
2) Tauwehenga Pāmahana Pai(PTC) whakamahana hauKo te wāhanga matua o te PTC ko te thermistor, e whakamahanatia ana e te waea whakamahana hiko, ā, he taputapu e huri tika ana i te pūngao hiko hei pūngao wera. Ko te pūnaha whakamahana hau PTC he huri i te matua hau mahana o te waka wahie tuku iho hei whakamahana hau PTC, ka whakamahi i te pā hau hei pana i te hau o waho kia whakamahanatia mā te whakamahana PTC, ā, ka tukuna te hau wera ki roto i te wāhanga hei whakamahana i te wāhanga. Ka pau tika te hiko, nō reira he nui te paunga pūngao o ngā waka hiko hou ina tahurihia te whakamahana.
3) Whakamahana wai PTC:Whakamahana whakamatao PTC, pērā i te whakamahana hau PTC, ka whakaputa wera mā te whakamahi hiko, engari ka whakamahana tuatahi te pūnaha whakamahana whakamatao i te whakamahana ki te PTC, ka whakamahana i te whakamahana ki tētahi pāmahana, kātahi ka pupuhi i te whakamahana ki roto i te hau mahana. I roto i te puku o te hau mahana, ka whakawhiti wera ki te hau e karapoti ana, ā, ka tukuna e te hau wera te hau wera ki roto i te wāhanga hei whakamahana i te kāpata. Kātahi ka whakamahanahia te wai whakamatao e te PTC ka whakahokia. He pono ake, he haumaru ake hoki tēnei pūnaha whakamahana i te whakamahana hau PTC.
4) Pūnaha hauhautanga papu wera: Ko te kaupapa o te pūnaha hauhautanga papu wera he rite tonu ki te pūnaha hauhautanga motuka tuku iho, engari ka taea e te hauhautanga papu wera te whakatutuki i te huringa o te whakamahana me te whakamatao o te kāpata
2. Tirohanga whānui mō te whakahaere wera o te pūnaha hiko
TeBTMSKua wehea te pūnaha hiko o te 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 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 ngā āhuatanga kawenga teitei. 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.
