He Aratohu Kōwhiringa Ārai Huka mō te Pouaka Whakamatao Ahumahi mō te Tiaki i te Matao

Ina heke te pāmahana i raro i te 0°C, tera pea ka pāngia te wai whakamatao i roto i te pouaka whakamatao ahumahi e te mōrearea huna: te whakawhanuitanga o te huka. I te hurihanga o te wai hei hukapapa, ka piki ake tōna rahinga, ā, ka taea te whakaputa i te pēhanga nui hei pakaru i ngā paipa whakarewa, hei kino i ngā hiri, hei whakapēke i ngā wāhanga papu, hei pakaru rānei i te whakawhiti wera. Ko te hua ka puta mai i ngā whakatikatika utu nui tae atu ki te wā whakamutu katoa o te mahi whakaputa.
Ko te huarahi tino whai hua ki te karo i ngā hapa o te hotoke ko te whiriwhiri me te whakamahi tika i te antifreeze.

Ngā Paearu Matua mō te Kōwhiri i te Ārai Huka
Hei whakarite i te mahi pono i roto i ngā taiao pāmahana iti, me tutuki i te ārai hukapapa e whakamahia ana i roto i ngā pouaka whakamatao ahumahi ngā whakaritenga e whai ake nei:
* Parenga Huka Kaha: He parenga huka rawaka i runga i te pāmahana iti rawa o te taiao.
* Ātete ki te Waikura: Hototahi ki te parahi, te konumohe, te maitai kore waikura, me ētahi atu konganuku pūnaha.
* Hototahi ki te Hiri: Haumaru mō ngā rauemi hiri rapa me te kirihou, me te kore e pupuhi, e pirau rānei.
* Te Tohanga Pūmau: Ka mau tonu te matotoru i ngā pāmahana iti hei karo i te kawenga papu nui rawa.
* Pūmautanga mō te Wā Roa: Ātete ki te waikura, te ua, me te pirau i te wā e mahi tonu ana.

Kōwhiringa Pai: Te Ārai Hukapapa e Hangai ana ki te Ethylene Glycol
He whānuitia te whakamahinga o te ārai hukapapa ethylene glycol i roto i ngā pūnaha whakamatao ahumahi nā te mea he teitei te kohua, he iti te hurihanga, ā, he tino pumau te matū. He mea tino pai mō ngā pūnaha porowhita kati e roa ana te wā e mahi ana.
* Mō ngā ahumahi kai, rongoā, ngā ahumahi akuaku rānei: Whakamahia te ārai hukapapa propylene glycol, ehara i te mea paitini engari he nui ake te utu.
* Kia tino karohia: Ngā rongoā ārai huka kei roto i te waipiro pērā i te etanoru. Ka taea e ēnei wai pūngāwerewere te whakararu i te raka o te kohu, te pakaru o te hiri, te waikura, me ngā mōrearea nui ki te haumaru.

Te ōwehenga whakaranu i tūtohutia
Mā te kukū tika o te glycol ka tiakina, engari kāore e whakararu i te whai huatanga o te whakamatao.
* Tauwehenga paerewa: 30% ethylene glycol + 70% wai whakakore iona, wai parakore rānei
Mā tēnei ka pai te taurite i waenga i te ārai i te huka, te ātete ki te waikura, me te whakawhiti wera.
* Mō ngā hotoke uaua: Whakanuia ake te kukū ina hiahiatia, engari karohia te nui rawa o te glycol e whakanui ana i te matotoru me te whakaiti i te marara o te wera.

Ngā Aratohu Horoi me te Whakakapinga
Kāore i te tūtohutia kia whakamahia te ārai huka mō te tau katoa. Mēnā kei runga ake te pāmahana o te taiao i te 5°C, me mahi ēnei e whai ake nei:
1. Ringihia rawatia te wai ārai huka.
2. Horoia te pūnaha ki te wai parakore kia mārama ra ano te rerenga.
3. Whakakīia anō te pouaka whakamatao ki te wai parakore hei wai whakamatao noa.

Kaua e Whakaranua ngā Waitohu Ārai Hukapapa
He rerekē ngā pūnaha tāpiri a ngā waitohu ārai huka. Mā te whakaranu i ēnei ka puta he tauhohenga matū, ka puta he paru, he hanganga tiēre, he waikura rānei. Me whakamahi tonu i te waitohu me te tauira kotahi puta noa i te pūnaha, ā, me horoi pai i mua i te whakawhiti hua.

Tiakina tō Pouaka Whakamatao Ahumahi me tō Raina Whakaputa
Mā te whakamahi i te ārai hukapapa whai tohu i te takurua, ehara i te mea ka tiakina te pouaka whakamatao ahumahi anake, engari ka tiakina hoki te haere tonu me te pono o te tukanga whakaputa katoa. Mā te whakarite tika ka pumau te mahi a te pouaka whakamatao ahakoa te tino makariri.
