Ko te huringa whakamatao pūwero e rua ngā wāhanga e whakamahi ana i ngā pūwero e rua, arā, he pūwero pēhanga iti me he pūwero pēhanga teitei.
1.1 E rua ngā wāhanga o te tukanga e piki haere ai te hau hauhautanga mai i te pēhanga mimiti ki te pēhanga whakatōtō
Ko te wāhanga tuatahi: I kōpeketia ki te pēhanga waenga e te kōpeketanga wāhanga pēhanga-iti i te tuatahi:
Ko te wāhanga tuarua: ka pēhia anō te hau i raro i te pēhanga waenga ki te pēhanga hauhautanga e te pūwero pēhanga-tiketike i muri i te whakamatao waenga, ā, ka oti te tukanga whakamatao i te huringa tauutuutu.
I te whakaputa i ngā pāmahana iti, ka whakaitihia e te intercooler o te huringa whakamatao kōpeketanga-rua-wāhanga te pāmahana tomo o te refrigerant i roto i te compressor wāhanga pēhanga-tiketike, ā, ka whakaitihia hoki te pāmahana tukunga o taua compressor anō.
I te mea ka wehea te tukanga whakamatao katoa e te huringa whakamatao kōpeketanga-rua-wāhanga kia rua ngā wāhanga, ka iti iho te ōwehenga kōpeketanga o ia wāhanga i tērā o te kōpeketanga-kotahi-wāhanga, ka whakaiti i ngā whakaritenga mō te kaha o ngā taputapu, ā, ka tino whakapai ake i te whai huatanga o te huringa whakamatao. Ka wehea te huringa whakamatao kōpeketanga-rua-wāhanga ki te huringa whakamatao oti waenga me te huringa whakamatao kore-oti waenga e ai ki ngā tikanga whakamatao waenga rerekē; ki te mea kei runga i te tikanga whakawhāiti, ka taea te wehewehe ki te huringa whakawhāiti wāhanga tuatahi me te huringa whakawhāiti wāhanga tuarua.
1.2 Ngā momo hauhautanga kōpeketanga e rua-wāhanga
Ko te nuinga o ngā pūnaha whakamatao kōpeketanga e rua-wāhanga e whiriwhiri ana i ngā pouaka whakamatao pāmahana reo me te pāmahana iti. E whakaatu ana ngā rangahau whakamātautau he pai ngā whakakapinga a te R448A me te R455a mō te R404A i runga i te whai huatanga o te pūngao. Ki te whakatauritea ki ngā momo whakakapinga ki ngā warowaihā fluorocarbons, ko te CO2, hei wai mahi e pai ana ki te taiao, he whakakapinga pea mō ngā pouaka whakamatao warowaihā fluorocarbons, ā, he pai hoki ngā āhuatanga taiao.
Engari mā te whakakapi i te R134a ki te CO2 ka heke te mahi a te pūnaha, inā koa i ngā pāmahana taiao teitei ake, he tino teitei te pēhanga o te pūnaha CO2, ā, me mātua tiaki motuhake i ngā wāhanga matua, inā koa te compressor.
1.3 Rangahau arotau mō te whakamatao kōpeketanga e rua ngā wāhanga
I tēnei wā, ko ngā hua rangahau arotau o te pūnaha huringa whakamatao kōpeketanga e rua-wāhanga koia ēnei:
(1) Ahakoa te whakanui ake i te maha o ngā rarangi ngongo i roto i te pouaka whakamatao, mā te whakaiti i te maha o ngā rarangi ngongo i roto i te pouaka whakamatao hau ka taea te whakanui ake i te horahanga whakawhiti wera o te pouaka whakamatao, me te whakaiti hoki i te rere o te hau i puta mai i te maha o ngā rarangi ngongo i roto i te pouaka whakamatao hau. Ina hoki ki tōna tomokanga, mā ngā whakapainga o runga ake nei, ka taea te whakaiti i te pāmahana tomokanga o te pouaka whakamatao mā te 2°C pea, ā, i te wā kotahi, ka taea te whakamana i te pānga whakamatao o te pouaka whakamatao hau.
(2) Kia mau tonu te auau o te pūwero pēhanga iti, ā, kia whakarerekētia te auau o te pūwero pēhanga teitei, kia rerekē ai te ōwehenga o te rahinga tuku hau o te pūwero pēhanga teitei. Ina pumau te pāmahana mimiti i te -20°C, ko te COP mōrahi ko te 3.374, ā, ko te ōwehenga tuku hau mōrahi e rite ana ki te COP ko te 1.819.
(3) Mā te whakataurite i ētahi pūnaha whakamatao pēhanga rua-wāhanga whakawhiti CO2 noa, ka whakatauhia he nui te awe o te pāmahana putanga o te whakamatao hau me te whai huatanga o te pūhiko pēhanga iti ki te huringa i tētahi pēhanga kua whakaritea, nō reira, ki te hiahia koe ki te whakapai ake i te whai huatanga o te pūnaha, me whakaiti te pāmahana putanga o te whakamatao hau, ā, me whiriwhiri i tētahi pūhiko pēhanga iti-wāhanga he pai te whakahaere.
