Ka whiriwhiria e ngā ētita e aro nui ana ki ngā taputapu ia hua ka arotakehia e mātou. Tērā pea ka whiwhi mātou i te komihana mēnā ka hoko koe mai i tētahi hononga. Me pēhea tā mātou whakamātautau i ngā taputapu.
He mīhini iti ngā hauhautanga kawe e huri ana i te hau wera, tawhito, me te hau makuku hei hau matao, maroke, me te hau pai. Hei mahi i tēnei, ka whakawhirinaki rātou ki te huringa whakamatao. Kāore koe e hiahia ki te ruku hohonu ki roto i tēnei huringa kia mārama ai, kia maioha ai hoki ki tōna whakamiharo.
Ko ngā hauhautanga katoa (me tō pouaka whakamātao) e whakawhirinaki ana ki te tukanga whakamiharo o te pupuhi i ngā matū pēhanga (e kiia nei ko ngā pouaka whakamātao) mā roto i ngā koropiko o ngā paipa whakarewa hei tango i te kaha wera ki te wāhi kāore e hiahiatia ana. I tetahi pito o te koropiko, ka pēhia te hauhautanga ki te wai, ā, i tetahi pito ka horapa hei kohu. Ehara i te mea ko te whakawhiti mutunga kore o te hauhautanga i waenga i te wai me te kohu te kaupapa o tēnei mīhini. Kāore he painga. Ko te kaupapa o te whakawhiti i waenga i ēnei āhua e rua ko te tango i te kaha wera mai i te hau i tetahi pito ka whakawhāiti ki tetahi pito. Inaa, koinei te hanganga o ngā āhuarangi iti e rua: te wera me te makariri. Ko te āhuarangi iti e hangaia ana i runga i te koiri makariri (e kiia nei ko te evaporator) ko te hau e tukuna ana ki roto i te rūma. Ko te āhuarangi iti e hangaia ana e te koiri (condenser) ko te hau e maka ana ki waho. Pērā i tō pouaka whakamātao. Ka neke te wera mai i roto i te pouaka ki waho. Engari mō te hauhautanga, ko tō whare, ko tō whare noho rānei he pouaka hei tango i te wera.
I te wāhanga makariri o te ara iahiko paipa, ka huri te hauhautanga mai i te wai ki te kohu. Me mutu tātou i konei nā te mea kua tupu tetahi mea whakamiharo. Ka koropupū te hauhautanga i roto i te ara iahiko makariri. He āhuatanga whakamiharo ngā hauhautanga, tae atu ki te hiahia ki te wera, tae noa ki te hau mahana i roto i te rūma ka ranea hei koropupū i te hauhautanga. I muri i te koropupū, ka huri te hauhautanga mai i te ranunga o te wai me te kohu ki te kohu katoa.
Ka mimitihia tēnei kohu ki roto i te pūwhakamahana, e whakamahi ana i te piston hei pēhi i te hau whakamatao ki te iti rawa o te rahinga. Ka pēhia te kohu ki roto i te wai, ā, ka tangohia te pūngao wera e kukū ana i roto ki te pakitara o te paipa whakarewa. Ka pupuhihia te hau e te hau mā roto i te paipa wera, ka whakamahanahia te hau, kātahi ka pupuhihia ki waho.
I reira ka kitea te merekara ā-pūkaha o te whakamatao, pērā i te mea e tupu ana i roto i ngā hauhautanga kawe.
Ehara i te mea ka whakamatao noa ngā hauhautanga i te hau, engari ka whakamaroke hoki. He nui te kaha wera e hiahiatia ana mō te whakatārewatanga o te makuku wai i roto i te hau hei kohu. Kāore e taea te ine i te kaha wera e whakamahia ana hei pauna i te makuku ki te inemahana, e kiia ana ko te wera huna. He mea nui te tango i te kohu (me te wera huna) nā te mea ka pai ake tō ahua i te hau maroke i te hau makuku. Mā te hau maroke ka māmā ake te mimiti o te wai mō tō tinana, koinei tō tikanga whakamatao taiao.
Ka whakapūpūhia e ngā hauhautanga pūkoro (pērā i ngā hauhautanga katoa) te makuku mai i te hau. Ka pā te mamaoa ki te koiri whakapūpū makariri, ka whakapūpūhia ki runga, ka maturuturu, ka rere ki roto i te ipu kohi. Ko te wai e whakapūpūhia ana mai i te hau ka kiia he whakapūpū, ā, he maha ngā huarahi ka taea te tukatuka. Ka taea e koe te tango i te paepae ka ringihia. Waihoki, ka whakamahia pea e te waeine he pā hau hei tuku makuku ki te wāhanga wera o te koiri (te whakapūpū), ka hurihia te makuku hei mamaoa, ka tukuna atu mā te putanga hau. I ētahi wā onge, ina tata te wāhi waikeri o te papa he hauhautanga pūkoro, ka rere pea te whakapūpū mā roto i ngā paipa. I ētahi atu wā, ko ngā paipa mai i te ipu waikeri o te hauhautanga ka arahi pea ki tētahi papu whakapūpū ka pupuhi i te wai ki te waikeri i waho, i hea atu rānei. He papu whakapūpū kei roto i ētahi hauhautanga pūkoro.
Kotahi te ngongo hau o ētahi hauhautanga kawe, e rua ia o ētahi. I ngā āhuatanga e rua, ka tukuna te taputapu me te ngongo kua momotu. Ka hono koe i tētahi pito o te ngongo ki te taputapu, ā, ko tētahi pito ki te anga matapihi. Ahakoa pēhea, kāore he taputapu e hiahiatia ana, ka whakapiri noa koe i te ngongo pērā i te pūtu kirihou nui. Ka mimitihia e ngā waeine ngongo kotahi te hau rūma kua whakamataohia, ā, ka whakamahia hei whakamatao i te koiri whakamatao wera. Ka pupuhihia e rātou te hau wera ki waho. He uaua ake ngā tauira ngongo takirua, ā, he nui ake te utu i ētahi tauira ngongo takitahi. Ka kukumehia e te ngongo kotahi te hau o waho, ā, ka whakamahia hei whakamatao i te koiri whakamatao wera, kātahi ka tukuna te hau wera mā te ngongo tuarua. Ko ētahi o ēnei taputapu ngongo takirua kua whirihorahia hei ngongo i roto i te ngongo, nō reira kotahi anake te ngongo e kitea ana.
He mea tika kia pātaihia ko tēhea tikanga te mea pai ake. Kāore he whakautu māmā. Ka kukume te tauira ngongo kotahi i te hau o te rūma i te wā e whakamatao ana te pūwhakamātao, ā, ka puta he hekenga pēhanga iti i roto i te whare. Mā tēnei pēhanga kino ka taea e te wāhi noho te kukume i te hau mahana mai i waho hei whakataurite i te pēhanga.
Hei whakaoti i te raruraru o te hekenga pēhanga, kua hangaia e ngā kaihanga he hoahoa ngongo takirua e whakamahi ana i te hau mahana o waho hei whakaheke i te pāmahana o te pūwhakamātao. Kāore te taputapu e whakakorikori i te hau i roto i te rūma, nō reira ka noho tonu te pēhanga hau i roto i te whare. Heoi, ehara tēnei i te otinga tino pai nā te mea e rua ngā ngongo mahana nui kei roto i tō rūma noho e ngana ana koe ki te whakamatao. Ka tukuna e ēnei ngongo mahana te wera ki roto i te wāhi noho, ka whakaiti i te whai huatanga o ngā taputapu. Ahakoa ka hoko koe i tētahi waeine me te kotahi, e rua rānei ngā ngongo, whiriwhiria te mea he nui rawa te kaha whakamatao kua whakatikatikaina i ia wā (SACC) ka taea e koe te utu. He mea whakahau tēnei whakatauranga whai huatanga pūngao mō ngā hauhautanga kawe i te tau 2017.
