He āhuatanga noa iho te kore e taea e te pāmahana o te pouaka tio o te hūpermakete te heke, ā, ka āta heke te pāmahana. Anei tētahi tātaritanga poto mō ngā take o te āta hekenga o te pāmahana, me te tumanako ka āwhina i ngā hoa o taua umanga anō.
1. Nā te ngoikore o te ārai wera, te mahi hiri rānei o te pouaka tio, he nui te ngaronga o te kaha whakamatao
Ko te take he ngoikore te mahi whakamahana, he koretake te matotoru o te papa whakamahana o ngā paipa, ngā papa whakamahana, me ērā atu, ā, kāore i te pai te pānga o te whakamahana me te tiaki wera. Ko te nuinga o te take he koretake te whiriwhiri i te matotoru o te papa whakamahana i te wā hoahoa, he kounga iti rānei o ngā rauemi whakamahana i te wā hanga. Hei tāpiri, i te wā hanga, ka pakaru pea te whakamahana me te mahi ātete makuku o te rauemi whakamahana, ka makuku, ka rerekē te āhua, ka memeha rānei te papa whakamahana. Ko tētahi atu take nui mō te nui o te ngaronga whakamatao ko te ngoikore o te mahi hiri, ā, ka nui ake te hau wera e uru mai ana i te turuturu. I te nuinga o te wā, ki te mea he hauhautanga kei runga i te rīpene hiri o te tatau, te hiri whakamahana rānei o te pouaka whakamātao, ko te tikanga kāore i te piri te hiri. Hei tāpiri, ko te whakatuwheratanga me te kati pinepine o ngā tatau, te maha atu rānei o ngā tāngata e tomo tahi ana ki te whare putunga ka nui ake te ngaronga o te kaha whakamatao. Me karo i te whakatuwheratanga o te tatau i te mea ka taea kia kore ai e uru te nui o te hau wera. Ae, ina hokona pinepinetia te taonga, ina nui rawa rānei te rahinga i hokona, ka piki tere te kawenga wera, ā, he roa te wā ka whakamatao ki te pāmahana kua tohua.
2. He matotoru rawa te hukapapa i runga i te mata o te mīhini whakapūngao, he nui rawa rānei te puehu, ā, ka heke te pānga whakawhiti wera.
Ko tētahi atu take nui mō te puhoi o te hekenga o te pāmahana ko te iti o te pai o te whakawhiti wera o te mīhini whakapūngao, ko te take matua o tēnei ko te paparanga huka matotoru, te nui rawa rānei o te puehu e kohia ana i runga i te mata o te mīhini whakapūngao. Nā te mea he iti iho i te 0°C te pāmahana o te mata o te mīhini whakapūngao pouaka whakamātao, ā, he teitei te haumākū, ka ngāwari te hukapapa, te tio rānei o te makuku o te hau i runga i te mata o te mīhini whakapūngao, ka pā ki te pānga whakawhiti wera o te mīhini whakapūngao. He matotoru rawa mō te paparanga huka mata o te taputapu e ārai ana i te mimiti, me whakarewa tonu.
Anei ētahi tikanga whakarewa māmā ake e rua:
① Whakawetohia kia rewa. Arā, whakamutua te pūwero, huakina te tatau, tukua kia piki te pāmahana, kātahi ka tīmata anō te pūwero i muri i te rewa aunoa o te paparanga huka.
②Hukapapa. I muri i te nekenga o ngā taonga i waho o te pouaka tio, horoia tika te mata o te paipa putanga hauhautanga ki te wai puna i te pāmahana teitei ake kia memeha, kia taka rānei i te paparanga hukapapa. Haunga te pānga whakawhiti wera ngoikore o te hauhautanga nā te hukapapa matotoru rawa, ka tino heke te pai o te whakawhiti wera o te hauhautanga nā te puehu matotoru i kohia ki te mata o te hauhautanga nā te horoinga roa.
3. He nui ake te hau, te hinu rānei kua whakamataohia i roto i te mīhini whakapūngao o te pouaka tio o te hūperamākete, ā, ka whakaitihia te pānga whakawhiti wera.
Kia tāpirihia anō te hinu whakamatao ki te mata o roto o te ngongo whakawhiti wera o te whakapūhau, ka heke tōna tauwehenga whakawhiti wera. Waihoki, ki te nui ake te hau i roto i te ngongo whakawhiti wera, ka heke te horahanga whakawhiti wera o te whakapūhau, ā, ka tino heke hoki tōna tauwehenga whakawhiti wera, ā, ka puhoi haere te tere o te hekenga pāmahana. Nō reira, i roto i te mahi me te tiaki o ia rā, me āta tango te hinu i te mata o roto o te ngongo whakawhiti wera whakapūhau, ā, me tuku te hau i roto i te whakapūhau i te wā tika hei whakapai ake i te pai o te whakawhiti wera o te whakapūhau.
Ka pā tika te whakarerekētanga hē, te aukati rānei i te takirere whakatere ki te rere o te hauhautanga ki roto i te evaporator. Ina nui rawa te whakatuwheratanga o te takirere whakatere, ka nui rawa te tere rere o te hauhautanga, ka piki ake hoki te pēhanga mimiti me te pāmahana mimiti, ā, ka puhoi te tere heke o te pāmahana; i te wā anō, ina iti rawa te whakatuwheratanga o te takirere whakatere, ka aukati rānei, ka piki ake te tere rere o te hauhautanga. Ka iti hoki te kaha whakamatao o te pūnaha, ā, ka puhoi hoki te tere heke o te pāmahana o te whare putunga.
I te nuinga o te wā, ka taea te whakatau mēnā he tika te rere o te hauhautanga o te takirere whakatere mā te tirotiro i te pēhanga mimiti, te pāmahana mimiti me te hukapapa o te paipa momi. Ko te aukati o te takirere whakatere he mea nui e pā ana ki te tere rere o te hauhautanga, ā, ko ngā tino take o te aukati o te takirere whakatere ko te aukati hukapapa me te aukati paru. Ko te aukati hukapapa nā te ngoikore o te whakamaroke i puta ai. Kei roto i te hauhautanga te makuku. Ina rere mā roto i te takirere whakatere, ka heke te pāmahana ki raro i te 0°C, ā, ka tio te makuku i roto i te hauhautanga ka aukati i te kōhao o te takirere whakatere; ko te aukati paru he mea nā te nui ake o te paru i runga i te tātari tomo o te takirere whakatere, kāore e maeneene te rere o te hauhautanga, ka hanga he aukati.
Hei tāpiritanga, ka taea hoki e koe te kōrero ki ngā kaihoko i ētahi whakatūpato mō te whakamahi i te pouaka tio:
1. Me waiho te pouaka tio mō te kawe tawhiti mō ngā hāora e rua i mua i te whakakā hei ārai i te kino o te pūnaha nā te nui rawa o te pēhanga. Mō te whakamahinga tuatahi, waiho kia rere te kāpata kau mō te hāora kotahi, kātahi ka whakauru i ngā taonga ki roto ina heke te pāmahana o te kāpata ki te pāmahana e hiahiatia ana i roto i te kāpata.
2. Me wehe ngā taonga ina whakatakotoria ki roto. Mēnā he kikī rawa, ka pā ki te rere o te hauhautanga.
3. Kaua te wāhi e karapoti ana i te pouaka tio e tata ki te pūtake wera, kia kore ai e pā te rā tika ki a ia, ā, kia pā kino ki te hua o te whakamatao.
4. I te wā e whakarewa aunoa ana, ka piki ake te pāmahana i roto i te pouaka tio i roto i te wā poto. Ina tūtaki te hau wera i waho o te kāpata ki te kai me te mata matao, ka whakatōtō te tomairangi ki runga i te mata o te kai. Ka tangohia te nuinga o te tomairangi ina tahurihia te mīhini mō te pouaka whakamātao, ā, ka toe tonu he iti o te tomairangi ki runga i te kai, he mea noa tēnei.
5. Ko te takirere ngira i runga i te whakapūhau o te pouaka whakamātao e whakamahia ana mō te whakamātautau pūnaha me te whakakī i te hauhautanga, ā, kaua e whakatuwheratia i ngā wā noa hei ārai i te turuturu o te hauhautanga.
6. Kaua te pouaka tio e penapena i ngā wai me ngā hau mura, pahū me ngā wai pūngāwerewere.
7. Kāore e taea e te hanganga o te whata tio te kawe i te taumaha neke atu i te 50kg ia mita tapawha (me tohatoha ōrite), ki te nui rawa ka kino te whata.
8. Kaua te whenua e totohu, ā, me noho papatahi, ki te kore ka pā ki te rerenga wai. Ka pā te rerenga wai ngoikore ki te whakamatao noa, ā, ka kino hoki te pā hau.
