Pereti taha whakapūmau-L/R
Ko te Whakapūmau (Whakapūmau), he wāhanga o te pūnaha whakamatao, he momo whakawhiti wera e taea ai te huri i te hau, te mamaoa rānei hei wai, ā, ka tere te whakawhiti i te wera i roto i te ngongo ki te hau e tata ana ki te ngongo. He tukanga werawera te tukanga mahi a te whakapūmau, nō reira he tino teitei te pāmahana o te whakapūmau.
He maha ngā pūwhakamātao e whakamahia ana e ngā tipu hiko hei whakamātao i te mamaoa putanga mai i ngā tāpine. Ka whakamahia ngā pūwhakamātao i roto i ngā tipu whakamatao hei whakamātao i ngā kohu hauhautanga pērā i te haukini me te freon. Ka whakamahia ngā pūwhakamātao i roto i te umanga hinu hei whakamātao i ngā hauwaiwaro me ētahi atu kohu matū. I roto i te tukanga whakatō, ko te taputapu e huri ana i te kohu ki te āhua wai ka kiia hoki ko te pūwhakamātao. Ka mahi ngā pūwhakamātao katoa mā te tango i te wera mai i te hau, i te kohu rānei.

I roto i te pūnaha whakamatao, ko te evaporator, te condenser, te compressor me te valve whakakā, ko ngā wāhanga matua e whā o te pūnaha whakamatao, ā, ko te evaporator te taputapu e kawe ana i te kaha whakamatao. Ka mimiti te refrigerant i te wera o te mea e whakamataohia ana kia puta ai te whakamatao. Ko te compressor te ngākau, e mahi ana ki te hongi, ki te pēhi, me te kawe i te kohu refrigerant. Ko te condenser he taputapu e tuku ana i te wera, ā, ka whakawhiti i te wera e mimitihia ana i roto i te evaporator me te wera e hurihia ana e te mahi a te compressor ki te reo whakamatao. Ko te valve whakakā he mahi ki te whakakā me te whakaiti i te pēhanga o te refrigerant, 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. I roto i te 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 wera, ngā mono whakakā, ngā kaiwhakahaere pēhanga me ētahi atu wāhanga, hei whakapai ake i te mahi. I hangaia mō te ōhanga, te pono me te haumaru.
E ai ki te āhua o te whakamatao, ka taea te wehewehe i ngā hauhautanga ki te momo whakamatao-wai me te momo whakamatao-hau, ā, e ai ki te kaupapa whakamahi, ka taea te wehewehe kia rua ngā momo: te momo whakamatao-kotahi me te momo whakamatao-whakamahana. Ahakoa te momo i hangaia, ko ngā wāhanga matua e whai ake nei te mea i hangaia.
Ko te hiahia mō te whakapūmau i ahu mai i te ture tuarua o te thermodynamics—e ai ki te ture tuarua o te thermodynamics, ko te ahunga rere ohorere o te pūngao wera i roto i te pūnaha kati he kotahi te ahunga, arā, ka taea anake te rere mai i te wera nui ki te wera iti, ā, i roto i te ao moroiti, ko ngā matūriki moroiti e kawe ana i te pūngao wera ka taea anake te rere mai i te raupapa ki te koretake. Nō reira, ina whai wāhi te pūngao o te miihini wera ki te mahi, me tuku hoki te pūngao ki raro, kia puta ai he āputa pūngao wera i waenganui i te taha whakarunga me te taha whakararo, ka taea te rere o te pūngao wera, ā, ka haere tonu te huringa.
Nō reira, ki te hiahia koe kia mahi anō te kawenga, me tuku tuatahi e koe te pūngao wera kāore anō kia tukuna katoatia. I tēnei wā, me whakamahi koe i te whakapūmau. Mena he teitei ake te pūngao wera huri noa i te pāmahana i roto i te whakapūmau, hei whakamatao i te whakapūmau, me mahi te mahi hangai (me te whakamahi i te pūwhakapūmau). Ka hoki te wai whakapūmau ki te āhua o te pūngao wera teitei me te iti, ā, ka taea te mahi anō.
Kei roto i te whiriwhiri i te pūwhakamātao te whiriwhiri i te āhua me te tauira, ā, ka whakatauhia te rere me te ātete o te wai whakamatao, te hau rānei e rere ana i roto i te pūwhakamātao. Me whai whakaaro te whiriwhiri i te momo pūwhakamātao ki te pūtake wai o te rohe, te pāmahana wai, ngā āhuatanga o te rangi, tae atu ki te kaha whakamatao katoa o te pūnaha whakamatao me ngā whakaritenga whakatakotoranga o te rūma whakamatao. I runga i te kaupapa o te whakatau i te momo pūwhakamātao, ka tatauhia te horahanga whakawhiti wera o te pūwhakamātao kia rite ki te kawenga whakamātao me te kawenga wera mō ia horahanga o te pūwhakamātao, kia taea ai te whiriwhiri i te tauira pūwhakamātao motuhake.
