Me whai whakaaro te hoahoa pūnaha ahi i roto i te rūma ma ki ngā whakaritenga o te taiao ma me ngā ture haumaru ahi. Me aro nui ki te aukati i te parahanga me te karo i te pokanoa o te hau, me te whakarite kia tere, kia whai hua hoki te urupare ahi.
1. Te kōwhiringa o ngā pūnaha ahi
Ngā pūnaha ahi hau
HFC-227ea: e whakamahia whānuitia ana, kāore e kawe hiko, kāore he para, he pai mō ngā taputapu hiko, engari me whai whakaaro ki te ātete hau (ko ngā rūma ma kāore he puehu he mea hiri pai te nuinga o te wā).
IG-541 (hau kore mahi): he pai mō te taiao, kāore hoki he paitini, engari me nui ake te wāhi rokiroki.
Pūnaha CO₂: kia tūpato ki te whakamahi, ka kino pea ki ngā kaimahi, ā, he pai anake mō ngā wāhi kāore he kai tirotiro.
Ngā āhuatanga e tika ana: ngā rūma hiko, ngā wāhi taputapu tika, ngā pokapū raraunga me ētahi atu wāhi e wehi ana i te wai me te parahanga.
Pūnaha rehu wai aunoa
Pūnaha tauhiuhi i mua i te mahi: ka pupuhihia te paipa ki te hau, ā, mēnā ka puta he ahi, ka mimitihia i te tuatahi, kātahi ka whakakīia ki te wai hei karo i te tauhiuhi tūpono me te parahanga (e taunakihia ana mō ngā rūma ma).
Kaua e whakamahi i ngā pūnaha mākū: kua roa te wā e whakakīia ana te paipa ki te wai, ā, he nui te tūponotanga o te turuturu.
Kōwhiringa pūwero: he mea kowiri tira, he ātete ki te puehu me te waikura, he hiri me te tiaki i muri i te tāutanga.
Pūnaha kohu wai pēhanga teitei
He penapena wai, he nui hoki te whai huatanga o te tinei ahi, ā, ka taea te whakaiti i te paoa me te puehu ā-rohe, engari me manatoko te pānga ki te ma.
Te whirihoranga o te tinei ahi
Kawe: He tinei ahi CO₂, he tinei ahi paura maroke rānei (whakanohoia ki roto i te rūma raka hau, i te ara raro rānei hei karo i te urunga tika ki te wāhi ma).
Pouaka tinei ahi kua whakauruhia: whakaitihia te hanganga e pupū ake ana kia kore ai e kohikohi puehu.
2. Hoahoa urutau taiao kore-puehu
Te hiri o ngā paipa me ngā taputapu
Me hiritia ngā paipa tiaki ahi ki te kapia epoxy, ki ngā ringaringa kowiri tira rānei i te pakitara hei ārai i te turuturu o ngā matūriki.
I muri i te tāutanga, me ārai wā poto ngā pīrere pupuhi, ngā pūoko paoa, me ētahi atu ki ngā taupoki puehu, ā, me tango atu i mua i te hanga.
Ngā rauemi me te maimoatanga mata
Ka tīpakohia ngā paipa maitai kore waikura, ngā paipa maitai piauau rānei, he maeneene, he ngāwari hoki te horoi i ngā mata hei karo i te puehu.
Me hanga ngā takirere, ngā pouaka, me ētahi atu mea ki ngā rauemi e kore e maringi, e ātete hoki ki te waikura.
Hototahitanga o te whakaritenga rere hau
Me karo te wāhi o ngā pūoko paoa me ngā pūwero i te pouaka hepa kia kore ai e whakararuraru i te taurite o te hau.
Me whai mahere whakapūhautanga hau i muri i te tukunga o te kaihoko tinei ahi hei ārai i te noho pūmau o te hau.
3. Pūnaha whakaoho ahi
Momo pūoko
Pūoko paoa mimiti (ASD): Ka whakamātau i te hau mā roto i ngā paipa, he tino aro, ā, he pai mō ngā taiao he nui te rere o te hau.
Pūoko paoa/wera momo-ira: Me whiriwhiri he tauira motuhake mō ngā rūma ma, he ātete puehu, he ārai-patū hoki.
Pūoko mura: He pai mō ngā wāhi wai, hau rānei e mura ana (pērā i ngā rūma rokiroki matū).
Hononga whakaoho
Me hono te tohu ahi hei whakaweto i te pūnaha hau hou (hei ārai i te horapa o te paoa), engari me pupuri tonu te mahi whakaputanga paoa.
I mua i te tīmatanga o te pūnaha tinei ahi, me kati aunoa te ārai ahi kia pai ai te kukū o te tinei ahi.
4. Te hoahoa o te putanga paowa me te ārai paowa me te putanga
Pūnaha whakaputanga paowa miihini
Me karo te wāhi o te putanga paowa i te wāhi matua o te wāhi ma hei whakaiti i te parahanga.
Me whakauru he ārai ahi ki te paipa whakaputa auahi (me hono, me kati hoki i te 70℃), ā, kaua te rauemi whakamarumaru pakitara o waho e whakaputa puehu.
Te whakahaere pēhanga pai
Ina tineia te ahi, whakawetohia te pūnaha hau, engari kia mau tonu te pēhanga pai i roto i te rūma ārai hei ārai i ngā poke o waho.
5. Ngā Whakatakotoranga me te Whakaaetanga
Ngā paerewa matua
Ngā whakaritenga Hainamana: GB 50073 "Ngā Whakaritenga Hoahoa Rūma Ma", GB 50016 "Ngā Whakaritenga Tiaki Ahi mō te Hoahoa Whare", GB 50222 "Ngā Whakaritenga Tiaki Ahi mō te Whakapaipai o Roto Whare".
Ngā tohutoro ā-ao: NFPA 75 (Parenga Taputapu Hiko), ISO 14644 (Paerewa Rūma Ma).
Ngā tohu whakaae
Whakamātautau kukū o ngā matū tinei ahi (pēnei i te whakamātautau rehu heptafluoropropane).
Whakamātautau turuturu (hei whakarite i te hiri o ngā paipa/hanganga ārai).
Whakamātautau hononga (whakaoho, whakamutu hauhautanga, tīmatanga o te putanga paoa, me ētahi atu).
6. Ngā whakatūpato mō ngā āhuatanga motuhake
Rūma ma koiora: karohia te whakamahi i ngā kai tinei ahi ka waikura pea i ngā taputapu koiora (pēnei i ētahi paura maroke).
Rūma ma hiko: me whakarite kia matua ki ngā pūnaha tinei ahi kore-arataki hei ārai i ngā kino hiko pūmau.
Rohe ātete-pahū: i honoa ki te hoahoa taputapu hiko ātete-pahū, tīpakohia he pūoko ātete-pahū.
Whakarāpopototanga me ngā whakaaro
Ko te ārai ahi i roto i ngā rūma ma me "whakamahi i te tinei ahi whai hua + whakaiti i te parahanga". He huinga e taunakitia ana:
Wāhanga taputapu matua: Tinei ahi hau HFC-227ea + kimi paoa mimiti.
Wāhi whānui: pūwero i mua i te mahi + pūoko paoa momo-ira.
Ara/putanga: tinei ahi + putanga paowa miihini.
I te wā hanga, me mahi tahi tata me ngā tohunga HVAC me ngā tohunga whakapaipai kia pai ai te hononga i waenga i ngā whare tiaki ahi me ngā whakaritenga horoi.
