He wāhanga tino nui te pūwhakamātao i roto i te pūnaha whakamatao. Hei pūwhakamātao e whakamahia whānuitia ana i roto i te rokiroki makariri, ka tika te whiriwhiri i te pūwhakamātao hau, ka pā tika ki te pai o te whakamatao.
Te Pānga o te Hukapapa Whakapūngao ki te Pūnaha Whakamatao
Ina mahi noa te pūnaha whakamatao o te whare putunga makariri, he iti iho te pāmahana o te mata o te mīhini whakapūngao i te pāmahana tomairangi o te hau, ā, ka tau te makuku o te hau ki runga i te pakitara o te ngongo. Mena he iti iho te pāmahana o te pakitara o te ngongo i te 0°C, ka tau te tomairangi hei hukapapa. Ko te hukapapa hoki te hua o te mahi noa o te pūnaha whakamatao, nō reira ka whakaaetia kia pania he hukapapa iti ki runga i te mata o te mīhini whakapūngao.
Nā te iti rawa o te kawe wera o te hukapapa, kotahi ōrau, kotahi ōrau rānei o te konganuku, nō reira ka hangaia e te paparanga hukapapa he ātete wera nui. Ina koa he matotoru te paparanga hukapapa, he rite ki te tiaki wera, kia kore ai e ngawari te memeha o te makariri i roto i te evaporator, ka pā ki te pānga whakamatao o te evaporator, ā, i te mutunga ka kore e taea e te rokiroki makariri te eke ki te pāmahana e hiahiatia ana. I taua wā anō, me ngoikore hoki te mimiti o te hauhautanga i roto i te evaporator, ā, ka taea te mimiti i te hauhautanga kāore i mimiti katoa ki roto i te compressor ka puta he aituā kohikohi wai. Nō reira, me ngana tātou ki te tango i te paparanga hukapapa, ki te kore ka matotoru ake te paparanga takirua, ā, ka kino haere te pānga whakamatao.
Me pēhea te whiriwhiri i tētahi evaporator e tika ana?
E mōhio ana tātou katoa, i runga i te pāmahana taiao e hiahiatia ana, ka whakamahia e te pouaka whakamatao hau ngā koki rerekē. Ko te koki hau e whakamahia whānuitia ana i roto i te umanga pouaka whakamatao he 4mm, 4.5mm, 6~8mm, 10mm, 12mm, ā, he koki rerekē te tawhiti o mua me muri. He iti te tawhiti o ngā koki o te pouaka whakamatao hau, he pai tēnei momo pouaka whakamatao hau mō te whakamahi i ngā taiao pāmahana teitei, ko te iti o te pāmahana o te rokiroki makariri. Ko te nui ake o te tawhiti e hiahiatia ana mō ngā koki hau whakamatao. Mena ka tīpakohia he pouaka whakamatao hau kāore i te tika, ka tere rawa te tere hukapapa o ngā koki, ka tere te aukati i te awa putanga hau o te pouaka whakamatao hau, ka puhoi te whakamatao o te pāmahana i roto i te rokiroki makariri. Kia kore e taea te whakamahi katoa i te tikanga kōpeketanga, ka piki haere tonu te whakapaunga hiko o ngā pūnaha pouaka whakamatao.
Me pēhea te whiriwhiri wawe i tētahi pūwero e tika ana mō ngā taiao whakamahinga rerekē?
Rokiroki makariri pāmahana teitei (pāmahana rokiroki: 0°C~20°C): hei tauira, te hauhautanga o te awheawhe, te rokiroki matao, te whare rokiroki matao, te rokiroki pupuri hou, te rokiroki hauhautanga, te rokiroki pakari, me ētahi atu, ko te tikanga he pai te whiriwhiri i te hau whakamatao me te tawhiti o te parirau 4mm-4.5mm.
Rokiroki makariri pāmahana-iti (pāmahana rokiroki: -16°C--25°C): Hei tauira, me whiriwhiri e ngā whare putunga pouaka whakamātao pāmahana-iti me ngā whare putunga ratonga pāmahana-iti ngā pā whakamatao me te tawhiti o te tara o te 6mm-8mm.
Whare putunga tio tere (pāmahana rokiroki: -25°C-35°C): ko te tikanga he whiriwhiri i tētahi pā hau whakamatao me te tawhiti o ngā tara o te 10mm~12mm. Mena he nui te haumākū o ngā taonga e hiahiatia ana mō te rokiroki matao tio tere, me whiriwhiri he pā hau whakamatao me te tawhiti o ngā tara rerekē, ā, ka taea e te tawhiti o ngā tara i te taha e tomo mai ai te hau te eke ki te 16mm.
Heoi, mō ētahi wāhi rokiroki makariri me ngā kaupapa motuhake, kāore e taea te whiriwhiri i te tawhiti o te hiku o te pā hau whakamatao kia rite ki te pāmahana o te wāhi rokiroki makariri. I runga ake i te ℃, nā te teitei o te pāmahana e tae mai ana, te tere o te whakamatao, me te haumākū nui o te utanga, kāore e tika te whakamahi i te pā hau whakamatao me te tawhiti o te hiku o te 4mm, 4.5mm rānei, ā, me whakamahi i te pā hau whakamatao me te tawhiti o te hiku o te 8mm-10mm. He rite anō hoki ngā wāhi rokiroki hou ki ērā mō te rokiroki hua me ngā huawhenua pērā i te kāriki me te aporo. Ko te pāmahana rokiroki e tika ana ko te -2°C. Mō ngā wāhi rokiroki hou, ngā wāhi rokiroki hauhautanga rānei me te pāmahana rokiroki i raro iho i te 0°C, me whiriwhiri hoki i te tawhiti o te hiku kaua e iti iho i te 8mm. Ka taea e te pā hau whakamatao te karo i te aukati i te awa hau i puta mai i te tere o te uira o te pā hau whakamatao me te pikinga o te whakapaunga hiko..
