Hangarau Whakamahana Hauhautanga Taiao-Hoa i roto i te Hanganga Āhuarangi
Ko te whanaketanga o te umanga hauhautanga (AC) ehara i te mea ko te whakamarie wera anake engari ko te pānga ki te taiao. Kei muri i te hau mātao e pārekareka ana ki a tātou, he wāhanga nui kei te mahi "i muri i ngā whakaaturanga": ko te hauhautanga. I roto i ngā tekau tau, kua tino whanake ngā momo hauhautanga e whakamahia ana i roto i ngā AC nā te mea kua whakamātauhia tā rātou takoha ki te whakahekenga ozone me te mahana o te ao. Nā tēnei i ara ake ai te hangarau hauhautanga e pai ana ki te taiao, koinei te paerewa hou i roto i te hanga AC hou.
He aha te Refrigerant, ā, he aha tōna hiranga?
Ko te hauhautanga te wai mahi e rere ana i roto i te pūnaha hauhautanga hei mimiti i te wera mai i te rūma, ka tukuna ki waho. I te wā o te huringa hauhautanga, ka huri te hauhautanga mai i te wai ki te hau, ka hoki anō ki te āhua, kia taea ai e ia te whakawhiti wera me te whai hua. Ko te mahi hauhautanga—tae atu ki te whakapaunga hiko, te kaha whakamatao, me te roa o te wā—he mea nui te pānga o ngā āhuatanga ā-tinana me te matū o te hauhautanga.
Heoi, ehara i te mea he haumaru mō te taiao ngā hauhautanga katoa. E rua ngā āhuatanga matua e arohia ana:
1. ODP (Pūmanawa Whakaiti Ozone): te pūmanawa ki te kino i te paparanga ozone.
2. GWP (Te Pūmanawa Whakamahana Ao): te pūmanawa ki te whakamāhana i te ao, ki te whakaritea ki te CO₂.
Ko te hauhautanga e pai ana ki te taiao he hauhautanga he tata ki te kore te ODP, ā, ko te GWP iti rawa hoki, me te kore e whakararu i te whai huatanga me te haumaru.
He Hītori Poto: Mai i ngā CFC ki ngā Pouaka Whakamātao o ēnei rā
I ngā rā o mua, he maha ngā wā i whakamahia ai ngā CFC (chlorofluorocarbons), pērā i te R-12, i roto i ngā hauhautanga. He tino pumau, he whai hua hoki ngā CFC, engari he nui te ODP, ā, he kino ki te paparanga ozone. Nā ngā ture ā-ao mā te Montreal Protocol i akiaki kia whakamutua te whakamahi i ngā CFC me te neke ki ngā HCFC (hydrochlorofluorocarbons), pērā i te R-22. He pai ake ngā HCFC, engari he ODP tonu, ā, i muri mai ka whakawhāitihia.
I muri i tērā, ka huri te umanga ki ngā HFC (Hydrofluorocarbons) pērā i te R-410A, kāore he ODP. Heoi anō, he nui te GWP o ngā HFC. Nā te aro nui ki te huringa āhuarangi, i whānau mai ngā whāinga whakaiti HFC mā te Whakatikatika Kigali. Nō reira, kei te tere haere ngā kaihanga hauhautanga ki te tango i ngā hauhautanga me te GWP iti iho, tae atu ki ngā momo taiao me te HFO.
Ngā Āhuatanga o ngā Pouaka Whakamatao Hoa-Taiao
Ka whakarōpūtia ngā pouaka whakamatao he mea pai mō te taiao mēnā ka tutuki i a rātou ngā āhuatanga e whai ake nei:
– ODP = 0 (kāore e kino te paparanga ozone)
– He iti te GWP (he iti iho i ngā HFC tuku iho)
– He tino pai te whakamahinga o te pūngao, nō reira he pai ake te whakamahinga o te AC
– Pūmau, hototahi hoki ki ngā wāhanga (hinu pēhi, paipa, hiri)
– Te haumaru whakahaere (he mārama ngā taumata mura me te paitini, ka taea te whakahaere kia rite ki ngā paerewa e tika ana)
I roto i te mahi, kāore he hauhautanga "tino tika". Nō reira, ka whakatauritehia e te hangarau AC hou ngā āhuatanga taiao, te mahi, te utu, me te haumaru.
Ngā Momo Pouaka Whakamatao Taiao Rongonui
1. R-32 (Difluoromethane)
He tino rongonui te R-32 i roto i ngā hauhautanga o te whare o te whakatupuranga hou. Ki te whakaritea ki te R-410A, he iti ake te GWP o te R-32, ā, he pai ake te pai o te whakamatao.
– ODP: 0
– GWP: tata ki te 675 (iti iho i te R-410A, arā, ~2088)
– Ngā Painga: he pai te mahi, he iti ake te hiahia mō te hauhautanga
– Te Wero: he ngawari te mura (A2L), nō reira me tika te hoahoa me ngā tikanga haumaru.
He maha ngā kaihanga e whiriwhiri ana i te R-32 nā te mea he māmā ake te whakamahi i tēnā i te whakawhiti ki ētahi atu matū whakamatao "tino rerekē".
2. R-290 (Pōpana)
He hau whakamatao taiao te R-290, he tino iti tōna GWP.
– ODP: 0
– GWP: tata ki te 3
– Ngā Painga: he tino pai ki te āhuarangi, ā, he whai hua hoki
– Ngā Wero: he mura ake (A3), nō reira he herenga kei runga i te nui o te utu hauhautanga me ngā whakaritenga haumaru pakari ake.
E whakamahia whānuitia ana te R-290 i roto i ngā pouaka whakamātao, ā, kua tīmata hoki te whakawhānui atu ki ētahi hauhautanga, inā koa i ngā mākete e tautokona ana e ngā ture me te rite o ngā hanganga.
3. R-744 (CO₂)
He kōwhiringa taiao ataahua te Refrigerant CO₂.
– ODP: 0
– GWP: 1 (tohutoro)
– Ngā Painga: he iti rawa te pānga ki te āhuarangi, ā, kāore e mura wawe
– Ngā Wero: te mahi i te pēhanga teitei me te hiahia ki te hoahoa pūnaha motuhake (me ātete ngā wāhanga ki te pēhanga, he uaua ake ngā mana whakahaere)
E whakamahia whānuitia ana te CO₂ i roto i ngā pūnaha whakamahana wai (ngā whakamahana wai papu wera) me ētahi tono arumoni.
4. HFO (Haidrofluoroolefin) me ōna Ranunga
I whakawhanakehia ngā HFO hei whakaiti i te GWP me te pupuri tonu i ngā āhuatanga rite ki ngā HFC.
– ODP: 0
– GWP: he tino iti te nuinga
– Ngā Painga: he pai te mahi, he "ātete ki ngā ture" ā muri ake nei
– Ngā Wero: te wātea, te utu, ā, he taumata mura anō hoki tō ētahi momo.
I roto i ngā mahi ahumahi, he maha ngā wā ka kitea te HFO hei hauhautanga whakaranu hei whakarite i te mahi me te pumau.
Te Tautoko i te Hangarau i roto i te Hanganga o te AC Hou
Ehara i te mea ko te whakakapi i te "whakakī" anake te whakamahinga o ngā hauhautanga e pai ana ki te taiao. Me whakarerekē e ngā kaihanga hauhautanga ā rātou hoahoa me ngā tukanga hanga kia pai ai te haumaru, te whai hua, me te roa. Ko ētahi o ngā hangarau tautoko e whakamahia whānuitia ana ko:
1. Hoahoa Whakawhiti Wera Pai Ake
Ka tino pai te mahi a ētahi pouaka whakamātao e pai ana ki te taiao i raro i ngā āhuatanga rere me te pēhanga rerekē. Nō reira, kua whakawhanakehia e ngā kaihanga:
– ngā paipa awa iti,
– he kikī ake ngā tara o te whakapūmau/whakapūhaumāota,
– te arotau i te rere o te wera hei whakapai ake i te whakawhiti wera.
Nā reira, ka taea e te hauhautanga te whakatutuki i te kaha whakamatao ōrite me te iti ake o te whakapaunga hiko.
2. Pūhiko Whakahurihuri o te Reanga Hou
Mā te hangarau inverter ka taea e te compressor te whakarerekē i te tere kia rite ki te tono kawenga. He mea nui tēnei nā te mea mā te whakakotahitanga o te inverter me te refrigerant whai hua ka taea:
– whakaitihia te whakamahinga hiko,
– kia mau tonu te pāmahana pumau,
– ka whakaiti i te huringa whakaweto-whakakā, ka tere ake ai te pakaru.
3. Pūnaha Haumaru mō ngā Pouaka Whakamatao Mura
Mō ngā kāwai hauhautanga A2L, A3 rānei, ka whakamahia e ngā kaihanga:
– pūoko turuturu,
– te hoahoa hauhautanga, te hoahoa anga rānei e ārahi ana i te rere o te hau,
– te herenga utu hauhautanga e ai ki ngā paerewa,
– te kōwhiringa o ngā wāhanga hiko hei whakaiti i te pūmanawa o ngā mura.
Mā tēnei huarahi, ka taea te whakahaere i ngā mōrearea i runga i te hangarau.
4. Ngā Rauemi me ngā Hinu Whakahinuhinu Hototahi
He rerekē ngā hinu whakapūngao e hiahiatia ana mō ngā momo hauhautanga rerekē (hei tauira, POE me ētahi atu momo). He mea nui anō hoki te hototahi ki ngā hiri/rapa hei ārai i ngā turuturu mō te wā roa. I te nuinga o te wā ka whakahaerehia e ngā kaihanga ngā whakamātautau tawhito o ngā rauemi, ngā whakamātautau wiri, me ngā whakamātautau huringa wera i mua i te tukunga o tētahi hua ki te mākete.
Ngā Painga o ngā Pouaka Whakamātao Hoa-Taiao mō ngā Kaihoko me te Taiao
Mō ngā kaihoko, he maha ngā wā ka haere tahi mai ngā pouaka whakamatao e pai ana ki te taiao me ngā hoahoa hauhautanga hou ake. Ko te pānga:
– he pai ake te penapena pūngao (ka taea te heke iho ngā pire hiko),
– te whakamatao tere ake, me te pumau ake,
– kia rite ake mō ngā ture kia pumau ake ai ngā ratonga me ngā wāhanga e tāpui ana.
Mō te taiao, he pānga nui te whakawhiti i ngā hauhautanga nā te mea ka pā kino te hauhautanga (mai i ngā turuturu, te mahi tiaki, te whakakorenga rānei o te waeine) ki te taiao. Mā te whakaiti i te GWP o te hauhautanga ka tino whakaiti i te "taputapu āhuarangi" o te hauhautanga, inā koa ka honoa ki te kaha o te whai huatanga o te pūngao.
Ngā Wero Whakatinanatanga i te Marae
Ahakoa he pai te hua, he maha ngā wero kei te whakamahi i ngā hauhautanga e pai ana mō te taiao:
1. Te rite o te tohunga hangarau me ngā paerewa ratonga: me whai whakangungu motuhake, me ngā taputapu me ngā tikanga hei whakahaere i ngā pouaka whakamātao mura.
2. Te hanganga hangarua me te whakakorenga: kei te ngoikore tonu te whakahaere i te hauhautanga kua whakamahia i roto i te maha o ngā wāhanga.
3. Ngā utu tīmatanga: ka nui ake te utu o ētahi hangarau rerekē me ngā hauhautanga, ahakoa ka ea tēnei i te nuinga o te wā mā te penapena hiko mō te wā roa.
4. Te ture me te tiwhikete: me piri ki ngā paerewa haumaru me ngā herenga kawenga hauhautanga kia pai ai te whakamahi.
Whakamutunga
Kua noho te hangarau hauhautanga e pai ana ki te taiao hei pou matua i roto i te hanga hauhautanga hou, e rite ana ki ngā tono o te ao ki te whakaiti i te pānga ki te paparanga ozone me te āhuarangi. Ko te whakawhiti mai i ngā CFC/HCFC ki ngā HFC haumaru-ozone, kātahi ki te R-32, ngā hauhautanga taiao (R-290, CO₂), me ngā HFO iti-GWP e whakaatu ana i te tere tonu o te auahatanga hauhautanga.
I ngā rā kei te heke mai, ko te angitu o tēnei hangarau ehara i te mea ka whakawhirinaki noa ki te momo hauhautanga, engari ki te hoahoa pūnaha whai hua ake, ki ngā paerewa haumaru pakari, me te pūnaha ratonga me te hangarua pakari. Mā tēnei huinga ka taea e te hauhautanga te pupuri i te whakamarie me te noho hei wāhanga o te otinga taiao, kaua hei pūtake o ngā raruraru hou.
