Pūrere hauhautanga waka(pūrere hauhautanga) e kiia ana kohauhautanga waka. E whakamahia ana hei whakatikatika me te whakahaere i te pāmahana, te haumākū, te ma o te hau me te rere o te hau i roto i te wāhanga o te motuka ki te āhua pai rawa atu, hei whakarato i te taiao eke whakamarie ki ngā pāhihi, hei whakaiti i te ngenge haere, me te waihanga i ngā āhuatanga mahi pai mō te taraiwa. Ko te nuinga o te wā kei roto ko ngā taputapu whakamatao, ngā taputapu whakamahana me ngā taputapu hauhautanga.
Tehauhautanga wakaKei roto i te pūnaha whakamatao he pūwero, he pūwhakamātao, he whakamaroke rokiroki wai, he takirere whānui, he pūwhakapūngao me te pupuhi. Ka honoa ngā wāhanga hei hanga i tētahi pūnaha kati me ngā ngongo parahi (ngā ngongo konumohe rānei) me ngā ngongo rapa pēhanga teitei. Ina mahi te pūnaha whakamatao, ka huri te hau whakamatao i roto i tēnei pūnaha kati i ngā āhua rerekē. E whā ngā tukanga matua o ia huringa:
(1) Tukanga kōpeketanga: Ka hongihia e te kōpeketanga te hau whakamatao pāmahana-iti me te pēhanga-iti i te putanga o te evaporator, ka kōpeketia hei hau whakamatao pāmahana-tiketike me te pēhanga-tiketike, kātahi ka tukuna atu i te kōpeketanga.
(2) Te tukanga whakamarara wera: Ka uru te hau whakamatao wera rawa atu i te pāmahana teitei me te pēhanga teitei ki te pūwhakapūmau. Nā te hekenga o te pēhanga me te pāmahana, ka whakapūmau te hau whakamatao hei wai, ā, ka tukuna he nui te wera.
(3) Tukanga whakawhāiti: I muri i te rerenga o te wai whakamatao me te pāmahana teitei me te pēhanga mā roto i te taputapu whakawhanui, ka piki ake tōna rahinga, ka heke tere te pēhanga me te pāmahana, ā, ka tukuna mai i te taputapu whakawhanui hei kohu (ngā pata iti).
(4) Te tukanga mimiti wera: Ka tomo te wai hauhautanga kohu ki roto i te evaporator. Nā te mea he iti iho te pāmahana koropupū o te hauhautanga i te pāmahana i roto i te evaporator, ka mimiti te wai hauhautanga hei hau. I roto i te tukanga mimiti, ka mimitihia e ia te nui o te wera e karapoti ana, kātahi ka tomo anō te kohu hauhautanga pāmahana iti me te pēhanga iti ki roto i te compressor. Ka whakahokia te tukanga o runga ake nei kia tutuki ai te kaupapa o te whakaheke i te pāmahana o te hau e karapoti ana i te evaporator.
