Ko te mahi a te pūwhakamātao mā te tuku i te hau mā roto i tētahi ngongo roa (he mea takai ki roto i tētahi solenoid), ka taea ai te ngaro o te wera ki te hau e karapoti ana. He kaha te kawe wera o ngā konganuku pēnei i te parahi, ā, he maha ngā wā ka whakamahia hei kawe i te mamaoa. Hei whakapai ake i te whai huatanga o te pūwhakamātao, he maha ngā wā ka tāpirihia ngā totohu wera he tino pai ngā āhuatanga kawe wera ki ngā paipa hei whakanui ake i te horahanga wera hei whakatere i te marara o te wera, ā, ka whakamahia hoki ngā pā hau hei whakatere i te kawe hau hei tango i te wera.
Hei kōrero mō te kaupapa o te pūwhakamātao, me mārama tuatahi ki te ariā o te pūwhakamātao. I te wā o te tukanga whakatō, ko te taputapu e huri ai te mamaoa ki te āhua wai ka kiia he pūwhakamātao.
Ko te mātāpono whakamatao o te nuinga o ngā pūwhakamātao: ko te mahi a te pūwhakamātao he pēhi i te mamaoa pēhanga iti ki roto i te mamaoa pēhanga teitei, kia heke ai te rōrahi o te mamaoa, kia piki ai te pēhanga. Ka hongihia e te pūwhakamātao te mamaoa wai mahi pēhanga iti mai i te pūwhakamātao, ka whakanui ake i te pēhanga, ka tukuna ki te pūwhakamātao. Ka whakamātaohia hei wai pēhanga teitei i roto i te pūwhakamātao. I muri i te whakawhāitihia e te takirere whakamātao, ka huri hei wai tairongo pēhanga. Kia heke te wai, ka tukuna ki te pūwhakamātao, ka mimiti i te wera ka mimiti hei mamaoa pēhanga iti, ā, ka oti te huringa whakamatao.
1. Ngā mātāpono taketake o te pūnaha whakamatao
I muri i te mimitinga o te hauhautanga wai i te wera o te mea e whakamataohia ana i roto i te evaporator, ka mimiti hei mamaoa pāmahana iti me te pēhanga iti, ka mimitia ki roto i te pūwhakamātao, ka pēhia hei mamaoa pēhanga teitei me te pāmahana teitei, kātahi ka tukuna ki roto i te pūwhakamātao. I roto i te pūwhakamātao, ka whāngaihia ki te reo whakamatao (wai, hau rānei) ka tukuna te wera, ka mimiti hei wai pēhanga teitei, ka whakakāhia ki roto i te hauhautanga pēhanga iti me te pāmahana iti e te takirere whakatere, kātahi ka tomo anō ki te pūwhakamātao ki te mimiti i te wera me te mimiti, ka tutuki ai te kaupapa o te huringa whakamatao. Mā tēnei, ka oti i te hauhautanga te huringa whakamatao mā roto i ngā tukanga matua e whā o te mimiti, te kōpeketanga, te whakamātao, me te whakawhāiti i roto i te pūnaha.
I roto i te pūnaha whakamatao, ko te pūwhakamahana, te pūwhakamātao, te pūwhakakoi me te takirere whakatere ngā wāhanga matua e whā o te pūnaha whakamatao. I roto i ēnei, ko te pūwhakamahana te taputapu e kawe ana i te pūngao makariri. Ka mimiti te pūwhakamahana i te wera mai i te mea e whakamataohia ana kia puta ai te whakamatao. Ko te pūwhakakoi te ngākau, ā, ko tana mahi he ngongo, he pēhi, he kawe hoki i te kohu o te pūwhakamahana. Ko te pūwhakamātao he taputapu e tuku ana i te wera. Ka whakawhiti i te wera e mimitihia ana i roto i te pūwhakamahana me te wera i hurihia e te mahi pūwhakakoi ki te reo whakamatao. Ka whakamātao, ka whakaiti hoki te takirere whakatere i te pūwhakamahana, ka whakahaere me te whakarite i te nui o te wai pūwhakamahana e rere ana ki roto i te pūwhakamahana, ā, ka wehea te pūnaha kia rua ngā wāhanga, te taha pēhanga teitei me te taha pēhanga iti. I roto i ngā pūnaha whakamatao tūturu, hei tāpiri atu ki ngā wāhanga matua e whā o runga ake nei, he maha ngā taputapu āwhina, pērā i ngā takirere solenoid, ngā tohatoha, ngā whakamaroke, ngā kaikohi, ngā mono whakakā, ngā kaiwhakahaere pēhanga me ētahi atu wāhanga, e whakamahia ana hei whakapai ake i te mahi. He ōhanga, he pono, he haumaru hoki.
2. Te kaupapa o te whakamatao pēhanga kohu
E whā ngā wāhanga matua o te pūnaha whakamatao kōpeketanga mamao kotahi-wāhanga: te kōpeketanga whakamatao, te pūwhakamātao, te pūwhakamomona me te takirere whakatere. Ka honoa ēnei e ngā paipa kia hanga he pūnaha kati. Ka haere tonu te hau whakamatao i roto i te pūnaha, ka huri te āhua, ka whakawhiti wera ki te ao o waho.
3. Ngā wāhanga matua o te pūnaha whakamatao
E rua ngā momo o ngā waeine whakamatao, arā, ngā waeine whakamatao wai-whakamatao me ngā waeine whakamatao hau-whakamatao. E ai ki te kaupapa whakamahi, e rua ngā momo: te waeine whakamatao kotahi me te momo whakamatao me te whakamahana. Ahakoa te momo, ko ēnei ngā wāhanga matua.
He taputapu te pūwhakamātao e tuku ana i te wera. Ka whakawhiti i te wera e mimitihia ana i roto i te evaporator me te wera kua hurihia e te mahi compressor ki te reo whakamatao. Ka whakamātao, ka whakaitihia hoki te pēhanga o te refrigerant e te takirere whakatere, ā, i te wā kotahi ka whakahaere me te whakarite i te nui o te wai refrigerant e rere ana ki roto i te evaporator, ā, ka wehea te pūnaha kia rua ngā wāhanga, te taha pēhanga teitei me te taha pēhanga iti.
