Ka whakaputa te pouaka whakamatao kiriata hinga i te wai hukapapa 0~1℃
Ko te nuinga o ngā mea kei roto i te pouaka whakamatao kiriata taka he pereti urunga me te kāpata kowiri tira. He whakawhiti wera e whakamatao ana i te wai ki te pāmahana e hiahiatia ana, ā, ko tēnei wai hukapapa ka whakamahia hei whakamatao i te nui o te hua i roto i te wā poto. I roto i te pouaka whakamatao kiriata taka, ka whakawhitihia e ngā pouaka whakamatao pereti urunga te wera mai i te kiriata angiangi o te wai e taka ana ki waho o ngā pereti. Ka haere te hauhautanga mā roto i ngā awa o roto o ngā pereti urunga. Ka taea te whakatutuki i te whakamatao o ngā wai i runga i te rerekētanga pāmahana whānui.
Ka pupuhihia te wai matao mahana ki roto i te paepae tohatoha, ā, ka rere i te tere whakahaeretia mai i te tohatoha i runga i te panera mā roto i te taha o waho o ngā pereti Platecoil (e kiia ana ko ngā pereti urunga) ki roto i te tāke. Ka haere te awa o roto o ngā pereti Platecoil mā roto i te reo whakamatao, ā, ka whakawhiti wera te wai matao mahana me te reo whakamatao mā te taha ā-kore. Ka whakamataohia te wai matao mahana ki te pāmahana e hiahiatia ana e te reo whakamatao. Ko te tikanga, ka whakamahia e te reo whakamatao te Freon, te Ammonia, te Glycol, me ngā hanganga motuhake ka taea te whakahaere me te glycol kei roto i te refrigerant.
He pereti whakawhiti wera motuhake te pereti koiri, he papatahi te hanganga, he mea hanga mā te hangarau whakarewa taiaho, ā, he pupuhi, he rere wai ā-roto tino pōrearea, ka hua ake he pai te whakawhiti wera me te tohatoha pāmahana ōrite. Ka taea te hoahoa me te hanga i roto i ngā āhua me ngā rahi rerekē e ai ki ngā hiahia o te kiritaki. Ko te taha waho o te pereti koiri he kāpata kua hoahoatia me te paepae tohatoha wai, te tatau o waho me ētahi atu. Ka taea te horoi ngāwari, nā te urunga mai i ngā taha katoa me te wāhi i waenganui i ngā pereti urunga e whakamomona ana.

1. Te tuku wai tonu, pumau hoki i te 0-1°C.
2. Kāore he whakapōturitanga ā-mīhini ahakoa te whakakī i te hukapapa.
3. Te tauwehenga whakawhiti wera teitei, me te utu whakahaere iti.
4. Hanganga pereti koiri hei ngāwari ki te horoi me te tiaki.
