Hei wāhanga nui o te pūnaha whakamatao rokiroki makariri, ka tīmata te hukapapa o te hau makariri ki runga i te mata o te evaporator ina mahi te hau makariri i te pāmahana i raro i te 0℃ me raro i te ira hau. I te roanga o te wā mahi, ka matotoru haere te paparanga hukapapa. Ngā take mō te hukapapa o te hau makariri (evaporator)
1. Kāore i te rawaka te tuku hau, tae atu ki te aukati i te paipa hau whakahoki, te aukati i te tātari, te aukati i te āputa o te tara, te pakaru o te pā hau, te tere iti rānei, me ētahi atu, ka hua ake te korenga o te whakawhiti wera, te hekenga o te pēhanga mimiti, me te hekenga o te pāmahana mimiti;
2. Ngā raruraru o te whakawhiti wera tonu. He maha ngā wā e whakamahia ana te whakawhiti wera, ā, ka heke te mahi whakawhiti wera, ka whakaiti i te pēhanga mimiti;
3. He iti rawa te pāmahana o waho. Ko te tikanga, kāore te whakamatao ā-iwi e heke iho i te 20℃, ā, ka kore e ranea te whakawhiti wera me te iti o te pēhanga mimiti i te whakamatao i roto i te taiao pāmahana iti;
4. Kua āraia te takirere whānui, kua pakaru rānei te pūnaha motuka pāhekoheko e whakahaere ana i te whakatuwheratanga. I roto i tētahi pūnaha e rere ana mō te wā roa, ka āraia e ētahi para te putanga takirere whānui, ā, ka kore e taea te mahi noa, ka whakaitihia te rere o te hauhautanga me te whakaheke i te pēhanga mimiti. Ka heke anō hoki te rere me te pēhanga i te whakahaere whakatuwheratanga rerekē;
5. Mā te whakawhāititanga tuarua, te piko o te paipa, te aukati rānei o ngā para i roto i te evaporator ka puta te whakawhāititanga tuarua, ka heke te pēhanga me te pāmahana i roto i te wāhanga i muri i te whakawhāititanga tuarua;
6. Kāore i te ōrite te pūnaha. Hei whakamārama, he iti te evaporator, he teitei rawa rānei te āhua o te mahi a te compressor. I tēnei wā, ahakoa kua tino whakamahia te mahi a te evaporator, ka iti te pēhanga momi me te heke o te pāmahana mimiti nā te āhua teitei o te mahi a te compressor;
7. Te korenga o te hauhautanga, te iti o te pēhanga mimiti me te iti o te pāmahana mimiti;
8. He teitei te haumākū i roto i te whare putunga, he hē rānei te tūranga o te mīhini whakapūngao, he maha rānei ngā wā e tuwhera ana, e kati ana te tatau o te rokiroki matao;
9. Te whakarewanga kāore i oti. Nā te korenga o te wā whakarewanga me te koretake o te tūranga o te taputapu tautuhi whakarewanga, ka tīmata te mīhini whakapūngao i te wā kāore anō kia whakarewanga katoatia. Whai muri i ngā huringa maha, ka tio te paparanga hukapapa o te mīhini whakapūngao hei hukapapa, ka kohia, ka nui haere.
Ngā tikanga whakarewa i te rokiroki makariri 1. Te whakarewa hau wera – he pai mō te whakarewa i ngā paipa o ngā rokiroki makariri nui, waenga me te iti: Tukua tika te kaiwhakamātao hau wera pāmahana teitei ki roto i te mīhini whakapūngao me te kore e āraihia, ā, ka piki te pāmahana o te mīhini whakapūngao, ka rewa te paparanga hukapapa me te hononga paipa, ka tihorea rānei. He ohanga, he pono hoki te whakarewa hau wera, he ngāwari ki te tiaki me te whakahaere, ā, kāore i te nui te uaua o te haumi me te hanga. 2. Te whakarewa wai – e whakamahia ana mō te whakarewa i ngā mīhini whakapūngao hau nui me te rahi waenga: Whakamahia tonutia te wai pāmahana noa hei rehu me te whakamatao i te mīhini whakapūngao hei whakarewa i te paparanga hukapapa. Ahakoa he pai te pānga whakarewa wai, he pai ake mō ngā mīhini whakapūngao hau, ā, he uaua ki te whakahaere mō ngā koiri whakapūngao. Ka taea hoki e koe te whakamahi i tētahi otinga he pāmahana hukapapa teitei ake, pērā i te 5% ki te 8% tote kukū, hei rehu i te mīhini whakapūngao hei ārai i te hukapapa. 3. Te whakarewa hiko – ko ngā ngongo whakamahana hiko te nuinga o te wā e whakamahia ana mō ngā pouaka whakamatao hau reo me te iti: Ko ngā waea whakamahana hiko te nuinga o te wā e whakamahia ana mō te whakarewa hiko i ngā paipa konumohe i roto i ngā rokiroki makariri reo me te iti. He māmā noa iho, he ngāwari hoki te whakamahi mō ngā pouaka whakamatao hau; engari mō ngā rokiroki makariri paipa konumohe, ehara i te mea iti te uauatanga o te hanga o te tāuta i ngā waea whakamahana hiko ki ngā tara konumohe, ā, he teitei hoki te tere o te rahunga ā muri ake nei, he uaua te tiaki me te whakahaere, he ngoikore te whai huatanga ōhanga, ā, he iti te tauwehenga haumaru. 4. Te whakarewa ā-ringa ā-ringa ā-ringa – e tika ana te whakarewa i ngā paipa rokiroki makariri iti: He ohanga ake te whakarewa ā-ringa i ngā paipa rokiroki makariri, ā, ko te tikanga whakarewa taketake. Kāore e taea te whakamahi i te whakarewa ā-ringa mō ngā rokiroki makariri nui ake. He uaua ki te whakahaere me te upoko e anga ake ana, ā, ka tere rawa te paunga o te kaha tinana. He kino ki te hauora te noho roa ki roto i te whare putunga. Ehara i te mea ngāwari te whakarewa pai, ka taea te whakapē i te evaporator, ā, ka kino pea te evaporator ka puta he aituā turuturu o te hauhautanga.
