Ko te kaupapa mahi o te pūnaha whakamatao kōpeketanga mamaoa o te hauhautanga waka
Ko te mātāpono mahi o te pūnaha whakamatao kōpeketanga mamaoa o te hauhautanga waka e whā ngā tukanga matua: te tukanga kōpeketanga, te tukanga whakatōtō, te tukanga whakawhanui me te tukanga mimiti.
te tukanga pēhi : Ka hongihia e te pēhi te hau whakamatao pāmahana iti me te pēhanga iti i te taha pēhanga iti o te evaporator, ka pēhia hei hau whakamatao pāmahana teitei me te pēhanga teitei, kātahi ka tukuna ki te pūwhakamātao hei whakamatao. Mā tēnei tukanga ka whakanuia te pāmahana me te pēhanga o te hau whakamatao.
te tukanga whakatōtō: ka tukuna te hau whakamatao pāmahana teitei me te pēhanga teitei e te pā hau me te hau e hangaia ana e te waka i roto i te whakatōtō, ā, ka whakatōtōhia hei hau whakamatao wai i te pāmahana reo me te pēhanga teitei. Ko te mahi a te whakatōtō he whakawhiti i te wera o te hau whakamatao ki te taiao o waho hei whakamatao.
Tukanga Whakawhanui : Ina haere te hauhautanga wai mā roto i te takirere whakawhānui, i te ngongo whakatere rānei, ka tino heke te pēhanga me te pāmahana, ka huri hei kohu mākū pāmahana iti me te pēhanga iti. Mā tēnei tukanga ka mimiti tetahi wāhanga o te hauhautanga, ka hanga he ranunga hau-wai kua rite ki te mimiti i te wera .
te tukanga mimiti : ka tomo te ranunga hau-wai o te hau mātao ki te mimiti, ka mimiti i te wera i roto i te waka, ka mimiti hei hau mātao pāmahana iti me te pēhanga iti. He whakawhiti wera whai hua te mimiti, e tango ana i te wera e mimitihia ana e te hau mātao i roto i te tukanga mimiti mai i te waka mā roto i te paipa o roto, kia tutuki ai te pānga whakamatao.
Ko ngā wāhanga o te pūnaha whakamatao hauhautanga motuka he pūwero, he pūwhakamātao, he takirere whānui (he ngongo whakatere rānei), he pūwhakamahana me ngā wāhanga whakahaere e rite ana. Ka mahi tahi ēnei wāhanga ki te hanga i tētahi pūnaha tohanga kati e rere tonu ai te hau whakamatao, e whakaoti ana i te whakawhiti mai i te hau ki te wai ki te hau.
Ko te whakamahinga o te pūnaha whakamatao kōpeketanga mamaoa o te hauhautanga waka ko te pūnaha hauhautanga ā-roto o te waka. Mā tēnei pūnaha, ka taea e te hauhautanga waka te whakaiti i te pāmahana i roto i te waka, me te whakarato i te taiao taraiwa whakamarie.
Ko te pūnaha whakamatao hauhautanga motuka he taputapu e whakamahi ana i te hauhautanga hei huri i roto i te pūnaha hei whakawhiti wera, e whakamahia ana hei whakaiti i te pāmahana i roto i te motuka. Ko te nuinga o te pūnaha he mea hanga ki ēnei wāhanga: te pūwhakakoi, te whakapūtā, te takirere whānui, te whakapūhau me ngā paipa me ngā takirere e hono ana i ēnei wāhanga.
Te kaupapa mahi
tukanga pēhi : Ka hongihia e te pēhi te hau whakamatao pāmahana iti me te pēhanga iti i roto i te evaporator, ka pēhia hei hau whakamatao pāmahana teitei me te pēhanga teitei, kātahi ka tukuna ki te pūwhakamātao hei whakamatao.
te tukanga whakatōtō: te whakamatao hau pāmahana teitei me te pēhanga teitei i roto i te whakatōtō ki te reo whakamatao (te nuinga he hau, he wai rānei) hei tuku i te wera, ka whakatōtō hei whakamatao wai.
tukanga whakawhanui : Ina haere te hauhautanga wai mā te takirere whakawhanui, ka heke te pēhanga me te pāmahana, ka huri hei mamaoa mākū pāmahana iti, hei mamaoa pēhanga iti hoki.
te tukanga mimiti : ka tāpirihia te kohu mākū i te pāmahana iti me te pēhanga iti ki roto i te mimiti, ka mimiti i te wera i roto i te motuka, ka mimiti hei hau whakamatao, kātahi ka hongihia anō e te kōpeke hei whakaoti i te huringa whakamatao.
whakamatao
Ko tētahi o ngā matū whakamatao e whakamahia whānuitia ana ko te R-134a (tetrafluoroethane), e mimiti ana i te nui o te wera ina hurihia mai i te wai ki te hau i roto i te evaporator, ā, ka hua ake te whakamatao.
Te papamuri hītori me te whanaketanga hangarau
He rite te kaupapa matua o te pūnaha whakamatao hauhautanga motuka ki te kaupapa matua o te hauhautanga o te whare, e whakamahi ana i te whakarerekētanga o te āhua o te hauhautanga hei whakatutuki i te whakamatao. I te whanaketanga o te hangarau, kua rite hoki ngā pūnaha hauhautanga motuka hou ki ngā momo pūoko me ngā pūnaha whakahaere hei whakatutuki i te whakahaere pāmahana tika ake me te whakamahinga pūngao whai hua ake.
