Ina whakahaerehia ngā taputapu whakamatao, ka ngāwari te mata o te koiri mimiti ki te huka. Mēnā he matotoru rawa te huka, ka pā ki te pānga whakamatao, nō reira me whakarewa i te wā tika. Mō te mahi whakarewa o ngā taputapu whakamatao pāmahana iti me ngā taputapu whakamatao pāmahana waenga, nā te rerekētanga o ngā awhe pāmahana, he rerekē anō hoki ngā wāhanga whakahaere e rite ana. Ko ngā tikanga whakarewa ko te whakamutu i te whakarewa, te whakarewa mā te wera whakaputa-ake, me te whakarewa mā te tāpiri i ngā taputapu o waho.
Mō ngā taputapu whakamatao pāmahana-waenga, ko te pāmahana whakahaere o te koiri mimiti he iti iho i te pāmahana pūngao tio, ā, he teitei ake i te pāmahana pūngao tio i te wā e kati ana, nō reira ko te tikanga kati whakarewa e whakamahia whānuitia ana mō ngā taputapu whakamatao pāmahana-waenga, pērā i ngā kāpata whakaaturanga pouaka whakamātao. I te wā e mahi ana, ko te pāmahana i roto i te kāpata he tata ki te 1°C, ā, ko te pāmahana o te koiri he tata ki te 10°C te iti iho i te kāpata. Ina kati te mīhini, ka teitei ake te pāmahana o te hau i roto i te kāpata i te pāmahana pūngao tio, ka haere tonu te hau i runga i te whakamatao, ā, ka puta te whakarewa tika mā te hau i roto i te kāpata me te pāmahana teitei ake. Ka taea hoki te whakarewa mā te wā, mā te matapōkere rānei. Ko te whakarewa wā he akiaki i te compressor kia mutu te rere mō tētahi wā. I tēnei wā, ka whakarewahia e te hau i roto i te kāpata te koiri. Ko te wā whakarewa me te roa o te wā whakarewa ka whakahaerehia e te taima e ai ki te raupapa kua whakaritea. Ko te tikanga ka whakaritea kia kati te compressor ina iti rawa te wera o te pouaka tio. Ka taea e te taima whakarewa te whakatakoto i ngā wā whakarewa maha i roto i ngā haora 24.
Mō ngā taputapu whakamatao pāmahana iti, he iti iho te pāmahana whakahaere o te mīhini whakapūngao i te pāmahana pūngao tio, ā, me whakamahi he tikanga whakarewa i te wā tika. Ina he iti rawa te pāmahana o te hau i roto i te pouaka tio i te pāmahana tio, me tuku te wera ki te mīhini whakapūngao hei whakarewa. Ko te wera e hiahiatia ana mō te whakarewa i te nuinga o te wā ka ahu mai i te wera o roto i te pūnaha me te wera o waho i waho o te pūnaha.
Ko te tikanga whakarewa i te hau wera e kiia ana ko te whakarewa hau wera. Ka whakamahia te mamaoa wera mai i te pūwero hei hono i te paipa putanga o te pūwero ki te tomokanga o te pūwero, ā, ka rere katoa te mamaoa wera kia rewa rawatia te paparanga hukapapa i runga i te pūwero. He tikanga ohanga, he tikanga penapena hiko hoki tēnei, nā te mea ko te kaha e whakamahia ana mō te whakarewa i ahu mai i te pūnaha tonu.
Mena he rārangi kotahi te pūwero, ā, he rārangi āhua-T te takirere whānui, ka taea te mimiti tika i te hau wera ki roto i te pūwero hei whakarewa. Mena he maha ngā paipa, me werowero te mamaoa wera i waenganui i te takirere whānui me te wehenga rere o te hauhautanga, kia rere ōrite ai te mamaoa wera ki roto i ia paipa o te pūwero, kia tutuki ai te kaupapa o te whakarewa taurite.
Ko te tikanga, ka tīmata te mahi whakarewa hukapapa mā te whakamahi i tētahi taima. Mō ngā taputapu rerekē, mō ngā āhua rerekē rānei, ka whakatakotoria te taima i ngā wā rerekē hei ārai i te pikinga o te whakapaunga pūngao, i te pāmahana hē rānei o te kai nā te roa rawa o te wā whakarewa hukapapa.
Ka taea te whakatau i te mutunga o te whakarewatanga mā te wā, mā te pāmahana rānei. Mēnā ka mutu te pāmahana, me whakatū he taputapu aro turuki pāmahana hei whakatau mēnā he teitei ake te pāmahana o te mīhini whakapūngao i te pāmahana tio. Mēnā ka kitea e te taputapu aro turuki pāmahana he teitei ake te pāmahana i te pāmahana tio, me tapahi tonu te mamaoa wera e tomo ana ki te mīhini whakapūngao kia whakahokia te pūnaha ki te mahi noa. I tēnei wā, ka tāutahia he taima miihini i te wā kotahi, ā, ka mutu te mahi whakarewatanga i runga i te tohu hiko o te wāhanga aro turuki pāmahana. Ko te tukanga taketake o te mahi a ia wāhanga ko: ina tae ki te pāmahana whakarewatanga kua whakaritea, ka kati te hononga taima, ka whakatuwheratia te takirere solenoid, ka mutu te rere o te pā, ka haere tonu te rere o te compressor, ā, ka tukuna te mamaoa wera ki te mīhini whakapūngao. Ina piki te pāmahana o te koiri ki tētahi uara, ka whakawhitihia ngā hononga thermostat, ka momotuhia te pito X o te taima, ā, ka mutu te whakarewatanga. Ina heke te pāmahana o te koiri ki tētahi uara, ka whakawhitihia ngā hononga thermostat, ā, ka tīmata anō te pā.
I te wā e whakarewa ana i te korohū wera, me whakarite e te taima te mahi a ngā wāhanga e whai ake nei i te wā kotahi:
1) Me whakatuwhera te takirere solenoid mamaoa wera;
2) Ka mutu te rere o te pā hau whakapūhau, ki te kore, kāore e taea te whakarewa pai i te hau makariri;
3) Me rere tonu te pūwero;
4) Ina kore e taea e te pana whakamutu whakarewa te whakamutu i te whakarewa, me whakarite te taima me te wā whakarewa mōrahi e whakaaetia ana;
5) Kua whakakāhia te whakamahana waikeri.
Ko ētahi atu taputapu whakamatao e whakamahi ana i tētahi pūtake wera o waho mō te whakarewa, hei tauira, te tāuta i tētahi taputapu whakamahana hiko tata ki te koiri. Ka whakahaerehia hoki tēnei tikanga whakarewa e tētahi taima. Ko te kaha ki te whakarewa ka ahu mai i tētahi taputapu o waho, nō reira kāore i te tino ohanga pērā i te whakarewa hau wera. Heoi, ki te roa te tawhiti o te paipa, he nui ake te whai huatanga o te whakarewa whakamahana hiko. Ina roa te paipa kohu wera, ka ngāwari te hauhautanga ki te haukū, ka hua ake he tino puhoi te whakarewa, ā, ka uru te hauhautanga wai ki te pūwero, ka puta te rere o te wai ki muri, ka kino te pūwero. Me whakahaere e te taima whakarewa wera te mahi a ngā wāhanga e whai ake nei:
1) I te nuinga o te wā, ka mutu te rere o te pā hau whakapūhau;
2) Ka mutu te mahi a te pūwero;
3) Kua whakakāhia te whakamahana hiko;
4) Kua whakakāhia te whakamahana waikeri.
Ko te pūoko pāmahana e whakamahia tahitia ana me te taima he taputapu whiu-rua kotahi-pou me ngā waea arataki e toru, he waea wera me te waea makariri. Ina piki te pāmahana o te koiri, ka whakakahangia te pito o te waea wera, ā, ina heke te pāmahana o te koiri, ka whakakahangia te pito o te waea makariri.
Hei karo i te roa rawa o te wā whakarewa, i te taumaha rawa rānei o te pūwero i muri i te whakarewatanga, ka taea te tāuta i tētahi pana whakamutu whakarewa, e kiia ana ko te pana whakaroa pā, ki runga i te pūnaha. Ko te pūmahana pāmahana o te pana whakamutu whakarewa kei te pito o runga o te mīhini whakamomona. Kia rewa katoa te paparanga hukapapa i runga i te koiri, ka taea e te pūoko pāmahana motuhake o te kaiwhakahaere whakamutu whakarewa te kite i te wera whakarewa, ka kati i ngā hononga o te kaiwhakahaere, ka whakakaha i te takirere solenoid whakamutu whakarewa. Whakahokia te pūnaha ki te whakamatao. I tēnei wā, kāore te mīhini whakamomona me te pā e tīmata tonu, engari ka tīmata te oma i muri i te whakaroa hei whakakore i te wera e toe ana i runga i te koiri, me te karo i te taumaha rawa o te pūwero nā te pēhanga momi nui i muri i te whakarewatanga. I taua wā anō, karohia te pupuhi hau makuku o te pā ki runga i te kai i roto i te kāpata.
