Te Pupuri i te Matao: Me pēhea te Whakaroa ake i te Roa o ngā Rawa e ngā Pūnaha Whakamatao Whakawhiti

Kupu Whakataki

Ko te roa o te ora o te whakawhiti hiko ka whakatauhia e tōna pāmahana mahi. Mō ia pikinga 6 ki te 8 nekehanga Celsius i runga ake i te pāmahana kua tohua, ka tapahia te roa o te wā whakamahana kia haurua. Nā tēnei whanaungatanga taketake, ehara ngā pūnaha whakamatao i te wāhanga āwhina anake, engari he mea nui hoki hei whakatau i te roa o te ora me te pono o te rawa.

Kua whanake te whakamatao o ngā whakawhiti hiko mai i ngā hoahoa ngāwari noa ki ngā pūnaha kaha matatau e kaha ana ki te tuku i ngā megawatts o te wera. Mā te mārama ki ēnei hangarau ka āwhina i ngā tohunga hokohoko ki te tautuhi i ngā taputapu e tika ana me te aromatawai i te mahi mō te wā roa.

Wāhanga Tuatahi: Ngā Kaupapa Taketake—Te Putanga o te Wera i te Whakawhitiwhiti

E rua ngā pūtake o te wera i roto i te whakawhiti hiko: ko ngā ngaronga kore-kawenga (te aukumetanga matua) me ngā ngaronga kawenga (te ātete takai). Me whakawhiti tēnei wera mā roto i ngā wāhanga maha i mua i te taenga ki te hau e karapoti ana.

I roto Whakawhiti Hinu-Rukuhias, ko te ara ko: ngā takai wera me te matua → te hinu e karapoti ana → te pakitara tāke, te mata rānei o te radiator → te hau taiao. Ko te whai huatanga o ia wāhanga e whakatau ana i te pāmahana mutunga o te whakawhiti hiko.

Ko ngā tikanga whakamatao e tohua ana e ngā waehere paerewa. Ko ngā reta tuatahi e tohu ana i te reo whakamatao ā-roto me te tohanga (O mō te hinu), ko ngā reta tuarua ia e whakaatu ana i te reo whakamatao o waho me te tikanga (N mō te taiao, F mō te kaha). Hei tauira, ko te tikanga o ONAN ko te Hinu Taiao, Hau Taiao—te whirihoranga māmā rawa.

Wāhanga Tuarua: Te Whakamatao Taiao—ONAN

Ko te whakamatao o ONAN e whakawhirinaki katoa ana ki ngā tukanga taiao: ka piki te hinu mahana, ka totohu te hinu matao, ā, ka rere noa te hau i roto i ngā whakamahana. Kāore he papu, kāore he pā hau, kāore hoki he wāhanga e neke ana.

He painga motuhake tēnei māmā: he mahi puku, he iti noa te tiaki, ā, he tino pono. Ko te tikanga, ka whakamahia te ONAN mō ngā whakawhiti hiko tae atu ki te 30 MVA i ngā āhuarangi ngawari. I ngā taiao makariri, ka taea e ia te mahi ki ngā kaha nui ake.

Ko te herenga ko te kaha ki te tuku wera. Ki te kore he rere ā-kaha, ka whakawhirinaki katoa te whakamatao ki ngā rerekētanga pāmahana me te horahanga o te mata. Mō ngā kaha teitei ake, me mahi ētahi atu mahi.

Wāhanga Tuatoru: Te Tāpiri i ngā Pā—ONAF

Ka tāpirihia e te ONAF (Oil Natural Air Forced) he pā hau ki ngā radiator, ka nui ake te whakawhiti wera. Ka panaia, ka kumea rānei te hau puta noa i ngā mata whakamatao, ka pai ake te mararatanga o te hau mā te 150 ki te 200 ōrau ki te whakataurite ki te whakawhiti wera māori.

Mā tēnei ka taea e te whakawhiti hiko kotahi te whakahaere i ngā kawenga teitei ake—ko te tikanga he pikinga 20 ki te 40 ōrau te rahinga. He mea whakamahi noa te ONAF ki ngā whakawhiti hiko i roto i te awhe 30 ki te 100 MVA, ā, he pai rawa te taurite o te utu me te mahi.

Ka taea te whakarite i ngā pā hau i runga i te pāmahana, i te kawenga rānei, me te mahi anake ina hiahiatia. Nā tēnei āheinga urutau ka rongonui te ONAF mō ngā tono me ngā tono ā-wā rerekē.

Wāhanga Tuawhā: Te Tohanga Hinu Āwhina—OFAF me ODAF

Kāore e ranea te nekehanga hinu māori mō ngā whakawhiti hiko nui rawa atu. Ka whakauruhia e te OFAF (Oil Forced Air Forced) ngā papu e huri tere ana i te hinu mā roto i te pūnaha whakamatao. Ka tere ake te whakawhiti wera mai i ngā takai ki ngā radiator, ka taea ai te whakanui ake i te kaha o te mana.

Ka whakatinanahia tēnei e te ODAF (Oil Directed Air Forced) mā te whakahaere i te rere o te hinu mā roto i ngā awaawa takai motuhake, kia pai ai te whakamatao o ngā wāhi wera rawa. He paerewa ēnei pūnaha mō ngā whakawhiti hiko neke atu i te 100 MVA, me ngā taiao uaua pērā i ngā āhuarangi wera, ngā whakamahinga ahumahi taumaha rānei.

He nui ngā taupatupatu: ka pau te hiko i ngā papu me ngā pā hau, ka puta te haruru, ā, me tiaki tonu. He nui ake te utu i te tīmatanga mō ngā whakawhiti hiko OFAF. Heoi, mō ngā tono kaha nui, kāore he huarahi kē atu.

Wāhanga Tuarima: Ngā Huarahi Whakamatao Motuhake

Whakamatao Wai.Ko ētahi o ngā whakawhiti hiko nui rawa atu, ngā waeine whakanekehanga hiko wai rānei, e whakamahi ana i ngā pūnaha OFWF (Oil Forced Water Forced). Nā te kaha wera pai o te wai ka taea te whakarite i ngā whakaritenga whakamatao kiato, engari ko te mōrearea o te turuturu me hiahia kia tino pai te hiri me te whakahaere pēhanga.

Whakawhiti Momo-MarokengāMō ngā whakaurunga o roto, ka whakawhirinaki ngā whakawhiti hiko momo-maroke ki te rere o te hau mā roto i ngā takai epoxy. Kei roto i ngā hoahoa ko te AN (Air Natural) ki te AF (Air Forced) me ngā pā hau. Ahakoa te whakakorenga o te mōrearea ahi hinu, he iti ake te whai huatanga o te whakamatao momo-maroke i te rumaki wai.

Ngā Hangarau Hou.Kei te tūhuratia e ngā rangahau hou te whakamatao mimiti, te wāhi e mimiti ai ngā rauemi huringa-āhuatanga i te wera mā te mimiti, ka tutuki ai ngā tauwehenga whakawhiti wera tino pai. Kei te rangahauhia hoki ngā paipa wera huringa-āhuatanga mō ngā whakawhiti momo-maroke, ka taea te whakaiti i ngā pikinga pāmahana me te whakapai ake i te ōritetanga.

Wāhanga Ono: Te Arotautanga Hoahoa me ngā Auahatanga o te Ao

Ko te hoahoa whakamatao o ēnei rā e whakawhirinaki ana ki ngā whanaketanga wai rorohiko (CFD) hei arotau i te whakatakotoranga o te radiator, te tawhiti o ngā tara, me ngā ara rere o te hau. Ahakoa ngā whakapainga iti o te whai huatanga ka nui te penapena pūngao i roto i ngā tekau tau o te mahi.

Kei te tūhuratia hoki e ngā kairangahau ngā pūnaha ranu e mahi ana i ngā momo rerekē i runga i ngā āhuatanga—ko te ONAN i ngā wā kawenga iti, ko te ONAF i ngā wā pīki—e whakataurite ana i te whai huatanga me te kaha whakamatao.

Mō ngā tohunga hokohoko, mā te mārama ki ēnei kōwhiringa ka taea te whakapai ake i ngā whakaritenga. Ko ngā whakaaro matua ko te pāmahana mōrahi o te taiao, ngā kōtaha kawenga noa, ngā here haruru, me ngā āheinga tiaki. Ehara i te mea ko te pūnaha whakamatao tika anake te tiaki i te whakawhiti hiko—engari ka whakanui ake i te hokinga mai o te haumitanga puta noa i tōna oranga katoa.

Whakamutunga

Kua whanake ngā pūnaha whakamatao whakawhiti hiko mai i ngā whakamahana māmā ki ngā huinga matatau o ngā papu, ngā pā hau, me ngā mana whakahaere. Ko te kōwhiringa i waenga i te ONAN, ONAF, OFAF, i ngā hoahoa motuhake rānei, e whakawhirinaki ana ki te kaha, te taiao, me ngā whakaritenga whakahaere.

Ko te mea e mau tonu ana ko te mātāpono matua: mā te whakamatao whai hua ka roa ake te ora o te whakawhiti hiko. He mea nui ia nekehanga, ā, ko te pūnaha whakamatao te taputapu matua mō te whakahaere i aua nekehanga. Mō te hunga e haumi ana ki ngā whakawhiti hiko, ehara i te mea whiriwhiri te mārama ki te whakamatao - he mea nui.
