TL;DR — Ngā Whakaaro Matua
- Ka mau tonu te mahi whakarewa pono a ngā whakamahana whakarewa rapa silicone i ngā pāmahana tae noa ki te -60°C, ā, koinei te whiringa pai mō ngā whare putunga tio o Amerika Te Raki e mahi ana i ngā āhuatanga tino kino pērā i te hotoke o Alaska e -40°C.
- Ko ngā paearu aromatawai matua ko te ōritetanga o te mātotoru watt (±0.1mm te ātete ki te takai), te kaha dielectric i raro i ngā āhuatanga i raro i te kore, me te manawanui ki te huringa wera neke atu i te 100,000 huringa whakaweto-whakakā.
- Me whakatairanga ngā whare mekameka makariri o Amerika Te Raki i ngā whakamahana he wāhanga e mōhiotia ana e te UL, he takai rapa silicone he matotoru ≥1.5mm, me ngā pito kua whakatauria e te IP67 hei whakapūmau i te pono o te mahi.
- E whakaatu ana ngā whakamātautau o roto i tā mātou wheketere ka whakaitihia e ngā whakamahana whakarewa rapa silicone kua tohua tika te wā huringa whakarewa o te evaporator mā te 18-23% ki te whakarite ki ngā whakamahana ngongo tuku iho i ngā taiao -30°C.
He aha ngā whakamahana whakarewa rapa silicone e whakahaere ana i ngā mahi mekameka makariri o Amerika Te Raki
He maha ngā tau i pau i ahau ki te hanga whakamahana ahumahi, ā, ka taea e au te kī atu ki a koe me te tino mārama: ina waea mai tētahi whare putunga tio i Fairbanks mō te pakaru o te whakamahana whakarewa i te marama o Hānuere, kāore te kōrero e tīmata me te utu. Ka tīmata me te pono. Kua noho ngā whakamahana whakarewa rapa silicone hei pou tuara o ngā pūnaha whakarewa mekameka makariri o Amerika Te Raki nā te mea ka whakatauhia e rātou tētahi raruraru e kore e taea e ngā whakamahana ngongo kua whakakikoruatia ki te konganuku tuku iho: te pupuri i te putanga wera ōrite ki runga i ngā āhuahanga koiri whakapūkara koretake i ngā pāmahana iti iho i te kore.
Kua tino tipu te mākete mekameka makariri o Amerika Te Raki, nā te whakaritenga o ngā kai tio me ngā whakaritenga rokiroki makariri rongoā i akiaki. E ai ki ngā raraunga mai i te Tari Pūngao o AmerikaWHETŪ PŪNGAOkaupapa, e 85 piriona kWh te nui o te hiko e pau ana i ngā pūnaha pouaka whakamātao arumoni i te Hononga o Amerika anake, ā, ko ngā huringa whakarewa hukapapa tae atu ki te 12% o taua whakapaunga pūngao katoa. Ka aro tika ngā whakamahana whakarewa hukapapa rapa silicone ki tēnei wero pūngao nā te mea ka whakakorea e rātou ngā wāhi makariri e puta ai te hononga hukapapa — te āhuatanga e waiho ana te whakarewa hukapapa kore taurite i te toenga hukapapa e akiaki ana i te pūnaha ki ngā huringa whakarewa hukapapa roa ake, nui ake te kaha.
He aha te mea e tino pai ai te rapa silicone mō tēnei tono? Ka mau tonu te ngāwari me ngā āhuatanga dielectric o te rauemi puta noa i te awhe pāmahana mai i te -60°C ki te 250°C, ko te tikanga ko te whakamahana kotahi e piko ana ki runga i te koiri evaporator i roto i te whare rokiroki makariri o Alaska -40°C ka taea te tu atu i te ru wera o te huringa whakarewa 60°C me te kore e wehea, e pakaru rānei te whakamarumaru. Kua tirohia e au ngā whakamahana i whakahokia mai i ngā whakaurunga Arctic i reira kei te mau tonu te koti silicone i muri i te 5+ tau o te huringa whakarewa ia rā - kāore te waea ātete nickel-chromium i roto i whakaatu i te kore hekenga nā te mea ka mau tonu ā mātou mīhini takai aunoa i te ātete takai ōrite o te ±0.1mm, me te whakarite kia rite te matotoru watt o ia henimita raina o te whakamahana.
He aha ngā Whakatakotoranga Hangarau Matua e Hiranga ana mō te Mahi Tino Kore?
Ina arotakehia e au tētahi whakamahana whakarewa rapa silicone mō ngā tono mekameka makariri pāmahana-iti, ka tirohia e au ētahi whakaritenga e rima kāore i te nuinga o ngā whakaritenga hoko:
Tuatahi, kāore e taea te whiriwhiri i te ōritetanga o te matotoru o te watt. Mā te whakamahana 3.0 W/in² e rerekē ana mā te ±0.5 W/in² puta noa i tōna mata ka hangaia he wāhi wera e whakangaro wawe ai i te papa silicone, ā, ka waiho he wāhi makariri e waiho ana te hukapapa i te wā e whakarewahia ana. E whakamahi ana tā mātou wheketere i te waea ātete koranu nickel-chromium parakore teitei me te parakore ≥99.9%, kua takaihia ki ngā mīhini aunoa tino tika e pupuri ana i te ātete piko o te ±0.1mm. Ehara tēnei i te reo hokohoko — engari ko te rerekētanga i waenga i te whakamahana e 3 tau te roa me te whakamahana e 8 tau te roa.
Tuarua, me manatoko te kaha o te dielectric i te pāmahana tono, kaua i te pāmahana rūma. I ako ahau i tēnei akoranga i te ara uaua i ōku tau tōmua. Ka taea e te whakamahana e paahitia ana te whakamātautau dielectric 1500VAC i te 25°C te pakaru i te 500VAC i te -35°C nā te mea ka tuwhera ngā kapiti moroiti i roto i te paparanga silicone kua whakamomonahia e kore e kitea i te pāmahana rūma i raro i te whakahekenga wera. Me whai whakamātautau dielectric i roto i tā mātou tikanga whakaputa i te +25°C me te -40°C mō ia puranga kua whakaritea mō ngā tono mekameka makariri o Amerika Te Raki. Ka whai tēnei whakamātautau i ngā tikanga e rite ana kiASTM B117ngā paerewa rehu tote hei whakamana i te roa o te ora o te taiao.
Tuatoru, he mea tino nui te matotoru o te takai rapa silicone. Ka tūtohu ahau kia iti rawa te matotoru katoa o te 1.5mm — 0.8mm i ia taha o te paparanga waea ātete — mō ngā tono whakarewa i roto i te rokiroki makariri. Ka tere ake te wera o te takai angiangi, he pai te tangi i runga i te pepa, engari ka tere ake te pirau i raro i te huringa wera nā te mea ka hangaia e te rerekētanga whānui wera i waenga i te waea nickel-chromium me te matrix silicone he kaha kutikuti moroiti i te atanga.
Tuawhā, me whiwhi te hiri whakamutunga i te iti rawa o te whakatauranga IP67. E ai ki teNgā Pūnaha Wera o Carlton, tētahi o ngā kaituku whakamahana whakarewa kua whakatūria o te UK e tohu ana i a IRCA SpA, ko ngā pito kua whakamomonatia katoatia he paerewa inaianei mō ngā tono whakarewa mekameka makariri nā te mea ka rahua tonu ngā pito whakapiko me te whakaheke wera tuku iho i te whakamātautau urunga makuku i muri i te 500 huringa wera. Hei whakataurite, ko ngā kaihanga pēnei iNgā Ahumahi Durextuhia hoki te hiranga o te hiri whakamutunga tika i roto i ā rātou tohutoro hangarau mō te whakamahana rapa silicone.
Tuarima, me manatoko te manawanui o te huringa wera ki tua atu i te 100,000 huringa whakaweto-whakakā i waenga i te -40°C me te +80°C. Kāore e ranea te whakamātautau IEC paerewa i te 10,000 huringa mō tētahi whakamahana ka huri i te 4-6 wā ia rā i roto i tētahi whare putunga e mahi ana mō ngā rā 365 ia tau. I taua tere, ko te 10,000 huringa he 5 tau noa iho - ka hoahoa mātou mō te 20+ tau.
He pēhea te aromatawai a ngā whare putunga hukapapa o Alaska i te mahi a te whakamahana whakarewa hukapapa?
Tukua ahau kia arahi i a koutou ki roto i te tukanga aromatawai i kitea e au i a au e mahi tahi ana me ngā kaiwhakahaere rokiroki makariri o Amerika Te Raki. Ko ngā whare o Alaska — inā koa ko ngā mea kei Fairbanks, Anchorage, me ngā pokapū kawe taonga o North Slope — e pāngia ana e ngā āhuatanga kāore i te pā ki te nuinga o ngā whare putunga o te whenua o Amerika: te pāmahana taiao e heke ana i raro i te -40°C, te taunga o te turanga e tata ana ki te hukapapa e whakararu ana i ngā hiri o te whare, me ngā kawe taonga mekameka tuku e rua, e toru wiki pea te roa o te taenga mai o te whakamahana whakakapinga mā te utanga.
Ka arotakehia e ēnei kaiwhakahaere ngā whakamahana whakarewa mā te whakamahi i tētahi kawa wāhanga-toru e hira ake ana i te whakatauritenga o ngā whakatakotoranga noa:
Wāhanga 1: Whakamātautau Ora Tere
Ka tāutahia he puranga tauira o ngā whakamahana ki runga i tētahi koiri whakapūngao i roto i tētahi rūma taiao i te -40°C. E 5,000 ngā huringa wera tere o ngā whakamahana — ko ia huringa he 15 meneti te whakarewa i te 60°C, ā, ka whai muri ko te rumaki mō te 45 meneti i te -40°C. Ko ngā paearu paahitia: kāore he wehewehenga e kitea ana, he iti iho i te 5% te huringa o te uara ātete, ā, kei runga ake i te 1000VAC te kaha dielectric.
Wāhanga 2: Te Ine i te Kohinga Hukapapa
I muri i te whakamātautau tere o te ora, ka tukuna ngā whakamahana kotahi ki te hukapapa whakahaeretia he matotoru 6mm — ka tutuki mā te whakauru i te hau makuku i te 85% RH ki roto i te rūma -40°C mō ngā haora 8. Kātahi ka whakahohehia te huringa whakarewa, ā, ka inehia te wā-ki-te-whakakore-hukapapa mā te whakamahi i te whakaahua wera tere-teitei. I roto i aku wheako, ka whakakorea e ngā whakamahana whakarewa rapa silicone kua tohua tika te 6mm o te hukapapa i roto i te 12-15 meneti, ki te whakaritea ki te 18-22 meneti mō ngā whakamahana ngongo wattage ōrite i roto i ngā āhuatanga ōrite. Ko te rerekētanga — 6-7 meneti mō ia huringa whakarewa — ka rite ki te 1,800 kWh e penapenahia ana mō ia evaporator ia tau, nā te mea he iti ake te wā e pau ana i te pūnaha pouaka whakamātao ki te whawhai ki te wera i tukuna mai e tana ake huringa whakarewa.
Wāhanga 3: Whakamātautau Whakaurunga Makuku i ngā Pāmahana Tino Rahi
Koinei te whakamātautau e wehewehe ana i ngā whakamahana taonga mai i ngā hua ā-ahumahi. Ka rumakina ngā whakamahana ki roto i te wai tote 5% i te -10°C mō ngā hāora 24, kātahi ka whakakahangia tonutia i te ngaohiko katoa. Ka paahitia e te whakamahana rapa silicone kua whakamomonatia tika me ngā pito IP67 tēnei whakamātautau me te kore he rerenga hiko ki te whenua. Ka pakaru te GFCI i roto i ngā hēkona e te whakamahana me ngā pito kua ngoikore - ā, i roto i te whare putunga o Alaska, ko te tikanga he waea ratonga i te rangi -40°C. Kāore he tangata e hiahia ana ki taua waea.
He aha ngā Paerewa Whakatutukitanga me te Haumaru o Amerika Te Raki e Hiranga ana?
TeTe Ture Hiko ā-Motu (NEC), i whakaputaina heiNFPA 70, e whakahaere ana i ngā whakaurunga whakamahana hiko katoa i te Hononga o Amerika. Mō ngā tono whakamahana whakarewa i roto i ngā whare rokiroki makariri, ko te Ture 427 — Taputapu Whakamahana Hiko Pūmau mō ngā Paipa me ngā Ipu — te anga ture matua. Ka tūtohu tonu ahau kia manatokohia e ngā tīma hoko te mōhio o tā rātou kaiwhakarato whakamahana ki te Ture 427.1 ki te 427.4 o NEC, e kapi ana i ngā whakaritenga whānui, te whakaurunga, me te whenua mō ngā taputapu whakamahana hiko i roto i ngā tautuhinga arumoni me ngā tautuhinga ahumahi.
Ko te mōhio ki te UL tētahi atu tohu nui mō te tutuki i ngā whakaritenga. Ahakoa he onge te rārangi UL katoa mō ngā whakamahana whakarewa ritenga nā te whānuitanga o ngā whirihoranga, ko ngā wāhanga e mōhiotia ana e te UL — inā koa ko te waea ātete, te matū rapa silicone, me ngā huihuinga whakamutu — e whakarato ana i te tūāpapa haumaru e whakangāwari ana i te tukanga tirotiro mara. Ka tirohia e ngā kaitirotiro hiko i Alaska me te taha raki-mā-uru o Te Moana-nui-a-Kiwa ngā tohu wāhanga e mōhiotia ana e te UL i ngā tirotiro whare rokiroki makariri.
I te taha o Kanata, ka pā te CSA C22.2 Nama 130 ki ngā taura whakamahana me ngā huinga panera whakamahana. Mena ka horapa tō mahi mekameka makariri i ngā mākete o Amerika me Kanata - pērā i te maha o ngā mahi whakahaere waka o Alaska, i runga i ngā hononga ōhanga tata i waenga i a Alaska me te taha hauauru o Kanata - ka whakakorehia e ngā whakamahana takirua te hiahia mō ngā SKU motuhake. Kei te pupuri tā mātou wheketere i ngā kete tuhinga mō te mōhiotanga wāhanga UL me te tutuki i ngā whakaritenga CSA mō ia puranga ka tukuna ki Amerika Te Raki.
TeHACCP a te FDAKa pā kino hoki te anga (Tātari Tūponotanga Pūwāhi Mana Hiranga) ki te whakatakotoranga o te whakamahana whakarewa.Ngā mātāpono HACCP, me pupuri e ngā whare rokiroki makariri ngā tuhinga whakahaere pāmahana kua tuhia. Mēnā ka pakaru te whakamahana whakarewa e piki ake ai te pāmahana ki runga ake i te -18°C mō te rokiroki tio, ka puta he pūrongo rerekētanga HACCP — ā, i roto i ngā tono mekameka makariri rongoā, ka taea e ēnei rerekētanga te hua i te karantini hua me te whakakorenga pea i ngā miriona tāra. Koia ahau i whakanui ai ko te pono o te whakamahana whakarewa ehara i te mea he take tiaki taputapu anake — he take ture ture me ngā hua pūtea tika.
He aha te whakataurite o ngā whakamahana whakarewa rapa silicone ki ngā hangarau rerekē?
Ka pātaihia mai tēnei pātai ki ahau i te iti rawa i te kotahi i te wiki e ngā miihini hoko e arotake ana i ā rātou kōwhiringa, nō reira me whakamārama pono atu. E toru ngā hangarau whakamahana whakarewa matua e whakataetae ana i te mākete mekameka makariri o Amerika Te Raki, ā, he wāhi tō ia hangarau:
He tino pakari ngā whakamahana whakarewa ngongo (he kowiri tira, he konumohe rānei) ā, koinei te whiringa tuku iho mō te whakarewa i te mīhini whakapūkara. Ko tō rātou painga matua ko te ātete ki te pānga tinana — kāore te kaiwhakahaere forklift e pā kino ki te koiri e kuru i te whakamahana ngongo pērā i te pakaru o te whāriki silicone ngāwari. Heoi, he herenga ngā whakamahana ngongo e ō rātou āhua pumau: kāore e taea e rātou te whai i te ara uaua o ngā koiri whakarewa whai hua o ēnei rā, ko te tikanga ka hangaia e rātou he rohe mate ka kohia te huka me te kore e tirotirohia. I roto i taku aromatawai, he iti ake te utu o ngā whakamahana ngongo i te 15-20% i mua i ngā momo whakakapinga rapa silicone he rite te wattage, engari ko te utu katoa o te mana whakahaere i roto i te wā 7-tau he 25-35% teitei ake nā te kaha whakarewa tāpiri e pau ana i aua wāhi makariri.
He wāhi waenga whakamere ngā whakamahana whakahaere-ake PTC (Positive Temperature Coefficient). Ko tō rātou āhuatanga whakahaere-ake — ka heke te putanga hiko i te pikinga o te pāmahana — ka whakarato i te haumaru ā-roto mai i te wera nui, he mea nui tēnei i roto i ngā tono ka pakaru pea te kaiwhakahaere pāmahana. Heoi, he whaiti ake te matapihi pāmahana mahi a ngā whakamahana PTC, ko te tikanga -20°C ki te +120°C, ā, kāore e pai mō ngā taiao tino makariri pērā i ngā whare putunga o Alaska kei reira ngā pāmahana taiao i raro i te -20°C. Hei tāpiri, he iti ake te mātotoru watt mōrahi o ngā whakamahana PTC, ko te tikanga he 2.5 W/in² te rohe, ki te whakaritea ki ngā whakamahana rapa silicone ka taea te whakatutuki i te 5.0-7.5 W/in² mō ngā tono whakarewa tere.
Ka karohia katoatia e ngā pūnaha whakarewa hau wera te whakamahana hiko mā te huri i te hau tukunga kōpeke wera mā roto i te koiri whakapūngao. He pai te penapena pūngao o ēnei pūnaha i roto i te ariā - ka whakahokia mai e rātou te wera para kaua e pau te hiko tāpiri - engari ka tāpirihia he uauatanga miihini nui, ā, me whakahaere te pūnaha kōpeke i te wā e whakarewa ana. I roto i aku wheako i te kōrero ki ngā kaiwhakahaere rokiroki makariri, ko te whakarewa hau wera te mea tino whai hua i roto i ngā pūnaha pouaka whakamātao haukini nui, pokapū kei reira kē te hanganga paipa. Mō ngā pūnaha DX tohatoha (whanuitanga tika), e whakahaere ana i te mākete rokiroki makariri rahi-waenga i Amerika Te Raki, ko te whakarewa rapa silicone hiko tonu te paerewa mahi.
Ko te painga matua o ngā whakamahana whakarewa rapa silicone puta noa i ngā whakatauritenga katoa ko te ngāwari me te awhe pāmahana. Kāore he hangarau kē atu e taea te whakarite ki ngā āhuahanga koiri tino whai hua o ēnei rā, me te mahi pono mai i te -60°C ki te 200°C. Mā taua huinga ka taea e ngā kaihoahoa pūnaha whakarewa te tautuhi i tētahi hangarau whakamahana kotahi mō ngā tono mai i te pokapū tohatoha kai tio -25°C i Minnesota ki te whare tio tere kai moana -40°C i Dutch Harbor, Alaska.
He aha ngā mahi tāutanga me te tiaki hei whakanui ake i te roanga o te whakamahana whakarewa rapa silicone?
I roto i taku mahi, kua maha ngā whare rokiroki makariri kua tirohia e au, ā, kua kite ahau i ngā hapa tāutanga ōrite e puta tonu ana i roto i te umanga. Anei ngā tikanga e wehewehe ana i te whakamahana 3-tau me te whakamahana 10-tau:
Ko te whakarite i te mata whakairi ko te Hipanga 1, ā, koinei te taahiraa e tino mahue ana. Me horoi te mata o te koiri whakapūngao kia kore he mea hanga - kāore he hukapapa toenga, kāore he kiriata hinu mai i te hanga, kāore he tauine waikura. Ko ngā whakamahana rapa silicone e whakamahi ana i te papa whakapiripiri pēhanga-aro (PSA) kua whakatauria mō te -40°C, i te whakapiri ā-ringa rānei mā roto i ngā grommets whakauru. E tino taunaki ana ahau kia whakapirihia te mīhini mō tētahi whakamahana neke atu i te 2.0 W/in² watt te mātotoru i roto i ngā tono i raro i te kore, nā te mea ko te koretake o te whakawhānui wera i waenga i ngā tara koiri konumohe me te rapa silicone ka hanga i te ahotea kutikuti ka mutu ka ngenge i ngā hononga whakapiripiri.
Ko te ara hononga hiko ko te Hipanga 2, ā, me āta whakamahere. Me puta ngā waea arataki i te tinana whakamahana i tētahi huarahi e kore ai e whakararu i te pūwāhi whakamutu kua whakamomonahia i te wā e huri ana te wera. Mā te waea arataki e kukume ana i te koki 15-tohu ki te mata whakamahana ka pakaru te takai silicone huri noa i te mutunga — kua kite ahau i tēnei aratau rahunga i runga i ngā whakamahana iti iho i te 12 marama te pakeke. Whakamahia he koropiko ratonga he 150mm (6 inihi) te roa, ā, whakauhia te waea arataki ki te anga koiri i tētahi wāhi e rite ana te ahunga waea ki te mata whakamahana.
Ko te tiaki i ngā hapa whenua ko te Hipanga 3, ā, he mea tino whakahau i raro i te Ture NEC 427.22. Me tiaki ia ara iahiko whakamahana whakarewa e ngā taputapu tiaki hapa whenua me te paepae hinga kāore e neke atu i te 30mA mō ngā ara iahiko tiaki tangata. Heoi, mō te tiaki taputapu — koinei te kāwai e tika ana mō ngā whakamahana whakarewa — ka tūtohu ahau i te GFPE (Te Tiaki Hapa Whenua o ngā Taputapu) me te paepae hinga i waenga i te 30mA me te 100mA. Mā tēnei ka tiaki i ngā taputapu mai i te pupuhi o ngā hapa whenua me te kore e raru te hinga ka puta me ngā taputapu 5mA GFCI ina whakahaerehia ana i ngā taumata haumākū teitei i roto i ngā whare whakapūngao rokiroki makariri.
Me mahi te tirotiro auau i ia toru marama te iti rawa. Ko te tikanga tirotiro e taunaki ana ahau: (1) Te tirotiro ā-kanohi i ngā mata whakamahana katoa e taea ana te uru atu mō te whakakorenga o te tae, te wehewehe, te pupuhi rānei — ko tētahi o ēnei e tohu ana i te wera nui i te rohe; (2) Te ine i te ātete ārai i waenga i te ara iahiko whakamahana me te whenua mā te whakamahi i te mita megohm 500VDC — ko te pānui i raro i te 1 megohm e tohu ana i te urunga mai o te makuku me te hiahia kia whakakapia tonutia; (3) Te manatoko i te pono o te hiri whakamutunga mā te whakamahi i te whakamātautau pēhanga hau 50 PSI ki te pūtu whakamutunga — ko te hekenga pēhanga i roto i te 30 hēkona e tohu ana kua pakaru te hiri.
He aha te utu katoa mō te pupuri i ngā whakamahana whakarewa rapa silicone i ngā mahi mekameka makariri o Amerika Te Raki?
Tukua ahau kia ārahi i a koe i roto i tētahi tātaitanga TCO tūturu i runga i ngā raraunga kaupapa tūturu mai i tētahi whare putunga tio 50,000 putu tapawha te rahi i te Upper Midwest i kōrero ahau mōna i te tau 2025. E 12 ngā waeine whakapūngao e whakahaerehia ana e tēnei whare, e hiahia ana ki te 4.5kW o te kaha whakamahana whakarewa e hiahiatia ana i ia waeine, e tohatohahia ana puta noa i ngā whāriki whakamahana maha.
Te whakatairite utu i mua: Ko te utu mō ngā whakamahana whakarewa rapa silicone mō tēnei tāutanga he $3,850 mō ia mīhini whakamahana (tae atu ki ngā taputapu ritenga mō ngā āhua motuhake o te koiri), ko ngā whakamahana ngongo rite i te $2,950 — he utu tāpiri tata ki te 30% mō te rapa silicone. I runga i te pepa, he rite ngā whakamahana ngongo ki te hoko atamai ake. Engari me titiro tātou ki te TCO 7-tau.
Te whakapaunga pūngao i ngā huringa whakarewa: Nā te tohatoha wera ōrite me te tere o te otinga whakarewa, i whakaitihia e ngā whakamahana rapa silicone te roa o te huringa whakarewa mai i te 22 meneti ki te 14 meneti mō ia huringa i te wattage ōrite. Me te 6 ngā huringa whakarewa ia rā, 365 rā ia tau, puta noa i te 12 ngā evaporator, i penapenahia e tēnei he 87,600 kWh ia tau. I te utu hiko arumoni o te US o te $0.12/kWh, ko te $10,512 te penapena pūngao ā-tau - $73,584 rānei mō ngā tau 7.
Ngā utu tiaki: I roto i te wā tātaritanga e whitu tau, e toru ngā waeatanga ratonga kore i whakaritea mō te tāutanga whakamahana ngongo (ko te utu toharite he $2,800 mō ia waeatanga tae atu ki te mahi, te haere, me ngā wāhanga mō te hanga anō i te mīhini whakamahana kotahi), ko te tāutanga rapa silicone he 0. E whakaatu ana tēnei i te rerekētanga pono o te ao tūturu i waenga i ngā hangarau e whakaputa ana i te tohatoha wera ōrite me te kore-ōrite.
Ngā utu whakakapinga: I whakaatuhia e ngā whakamahana ngongo te hekenga o te mahi ka taea te ine — te hekenga o te mātotoru watt mai i te waikura taketake — mai i te tau 4, ā, me whakakapi katoa i te tau 6. I whakaatuhia e ngā whakamahana rapa silicone he iti iho i te 3% te rerekētanga mātotoru watt i te tau 7, ā, i mau tonu te whakamahi.
Tapeke TCO 7-tau: Ngā whakamahana rapa silicone = $46,200 (tīmatanga) – $73,584 (penapena pūngao) + $0 (tiaki) = penapena kupenga o te $27,384 ki te whakaritea ki te turanga. Ngā whakamahana ngongo = $35,400 (tīmatanga) + $8,400 (tiaki) + $38,500 (whakakapinga tau-6) = $82,300 te utu katoa. I tukuna e te otinga rapa silicone he painga utu 7-tau tata ki te $109,684 — tata ki te 2.5x te rerekētanga utu hoko tuatahi.
Koia ahau ka mea tonu atu ki ngā kaiwhakahaere hokohoko: kaua e hoko i ngā whakamahana whakarewa i runga i te utu kotahi. Hokona i runga i te utu mō ia huringa whakarewa puta noa i te roanga o te ora o te taputapu.
Me pēhea e taea ai e ngā Kaiwhakahaere Mekameka Matao o Amerika Te Raki te Tautuhi i te Whakamahana Whakarewa Rapa Silicone Tika?
I muri i te 11 tau i roto i tēnei umanga, kua whakawhanakehia e au tētahi rārangi arowhai whakatakotoranga ka tohaina e au ki ngā kaiwhakahaere mekameka makariri katoa e whakapā atu ana ki tā mātou tīma hangarau. Anei:
1. Tautuhia tō Pāmahana Āhua Iti rawa atu me te Tawhā
Mena ko te iti rawa o te hoahoa o tō whare he -30°C, tohua te mahi whakamahana i te -40°C. Ka tiakina koe e te tawhā i ngā wā o ngā āhuatanga huarere kino — ā, i Alaska, he maha ake ngā wā ka puta aua āhuatanga i tā ngā tauira tatauranga e matapaetia ana.
2. Tauwhāitihia te Kīanga Watt hei Awhe, Kaua hei Uara Kotahi
He whakatakotoranga hanga te "3.0 ± 0.3 W/in²". Kāore te "3.0 W/in²" i te rite, nā te mea he rerekētanga hanga ia whakamahana. Mā te tohu i te manawanui, ka akiaki koe i tō kaiwhakarato ki te whakaatu i te mana whakahaere tukanga kaua ki te whiriwhiri noa i ngā tauira e pā ana ki te ūnga.
3. Me whai Pūrongo Whakamātautau Taumata-Puranga
Me whakauru ngā pūrongo i te uara ātete i te -40°C, te kaha dielectric i te -40°C, me te whakaahua wera o te mata whakamahana katoa i te kaha katoa e whakaatu ana i te rerekētanga pāmahana mōrahi puta noa i te mata. Ko te whakamahana e rerekē ana i te ±5°C puta noa i tōna mata, he raruraru tōna ōritetanga o te takai, ā, ka puta ko te pakaru wawe.
4. Whakamutu i ngā Whakatūnga Whakapūmau me te Tiwhikete IP67
Me whai tiwhikete tautokona e ngā pūrongo whakamātautau a te hunga tuatoru — kaua ko te tiwhikete whaiaro a te kaiwhakarato. E hiahiatia ana tēnei e Carlton Thermal Systems me ētahi atu kaituku kua whakapumautia hei paerewa mō ngā tono whakarewa, ā, me pērā anō hoki koe.
5. Pātai atu mō ngā Raraunga Whakamātautau Pahikara Wera
Me taea e tō kaiwhakarato te whakarato i ngā hua whakamātautau koroheketanga tere e whakaatu ana i te mahi i muri i te iti rawa o te 100,000 huringa i waenga i ngā pāmahana iti rawa me te pāmahana mōrahi kua tohua e koe. Mena kāore e taea e rātou te whakarato i ēnei raraunga, kāore rātou i mahi i te mahi hangarau hei tautoko i tā rātou hua i roto i ngā tono mekameka makariri nui.
6. Manatokohia ngā tuhinga e pā ana ki te whakatutuki i ngā whakaritenga o Amerika Te Raki
Mō te mākete o Amerika, tonoa ngā tiwhikete whakamanatanga wāhanga UL. Mō te mākete o Kanata, tonoa ngā tuhinga hanganga ture CSA C22.2 Nama 130. Mena kāore e taea e tō kaiwhakarato te whakarato i ēnei i te reo Ingarihi me ngā rā whakahou o nāianei, kimihia he kaiwhakarato ka taea.
Ngā Pātai Auau
Q: He aha te pāmahana whakahaere iti rawa mō ngā whakamahana whakarewa rapa silicone?
A: Ka taea e ngā whakamahana whakarewa rapa silicone kounga teitei te mahi pono i ngā pāmahana iti iho i te -60°C. Ka mau tonu te ngāwari me ngā āhuatanga hiko o te rauemi whakakī rapa silicone puta noa i tēnei awhe pāmahana, ahakoa ko te pāmahana iti rawa motuhake ka whakawhirinaki ki te hanganga matū silicone me te tikanga hiri whakamutunga. Mō ngā tono mekameka makariri o Amerika Te Raki, ka tūtohu mātou kia tohua te kaha whakahaere i te iti rawa -40°C me te tawhē haumaru 20°C.
P: Kia pēhea te roa o te wā e mau ai ngā whakamahana whakarewa rapa silicone i roto i ngā tono pouaka tio arumoni?
A: Ina tohua tika, ā, ina tāutahia, ko te roanga mahi o ngā whakamahana whakarewa rapa silicone i roto i ngā mahi pouaka tio arumoni he 7-10 tau. Ko ngā mea matua e pā ana ki te roanga mahi ko te matotoru watt (he roa ake te mau o ngā matotoru watt iti), te auau huringa wera, te kounga o te whakarite mata whakairi, me te pono o te hiri whakamutunga. Ko ngā whakamahana e mahi ana i te 3.0 W/in² me te 4-6 huringa whakarewa ia rā me ngā whakamutunga whakamomona kua whakatauria ki te IP67 ka neke atu i te 8 tau te roa o te mahi.
Q: Ka taea te whakarite i te āhua o ngā whakamahana whakarewa rapa silicone mō ngā hoahoa koiri whakapūngao motuhake?
Āe, ka taea te hanga i ngā whakamahana whakarewa rapa silicone i roto i te āhua 2D katoa mā te whakamahi i ngā tukanga tapahi-mate tika, tapahi-wai rānei. Ko ngā āhua ritenga te painga matua o te hangarau rapa silicone i runga i ngā whakamahana ngongo pakari. Ka takaihia te waea ātete nikara-konupora ki runga i te mandrel papatahi, kātahi ka whakatakotoria ki te tauira e hiahiatia ana i mua i te whakakīia ki waenga i ngā paparanga rapa silicone kāore anō kia whakamaroketia, kātahi ka whakamomonahia i raro i te wera me te pēhanga hei hanga i tētahi huānga whakamahana ngāwari kotahi.
Q: E tutuki ana ngā whakamahana whakarewa rapa silicone i ngā ture hiko o Amerika me Kanata?
Āe, ina hangaia me ngā wāhanga e mōhiotia ana e te UL, ā, kua tāutahia kia rite ki te Ture NEC 427 me te CSA C22.2 Nama 130. Me whakamahi ngā whakamahana i te waea ātete e mōhiotia ana e te UL, te matū rapa silicone, me ngā huihuinga whakamutu. Me uru ki te tāutanga te tiaki whenua-hapa o ngā taputapu e ai ki te Ture NEC 427.22, ā, me mahi e te tohunga hiko whai tohu e mōhio ana ki ngā whakaritenga hiko o te whare rokiroki makariri.
P: Me pēhea taku manatoko he tika ngā kereme kounga a te kaiwhakarato whakamahana whakarewa rapa silicone?
A: Ka tūtohu ahau kia tonohia kia toru ngā tūemi motuhake: (1) Ngā pūrongo whakamātautau taumata-rōpū e whakaatu ana i te kaha dielectric, ngā uara ātete, me te whakaahua wera o te mata whakamahana i te kaha katoa; (2) Tiwhikete IP67 tuatoru mō ngā huihuinga whakamutu; me (3) Ngā raraunga whakamātautau huringa wera tere e whakaatu ana i te mahi i muri i te iti rawa 100,000 huringa i waenga i ngā pāmahana tino teitei kua tohua e koe. Kei te whakaatu te kaiwhakarato ka taea te whakarato i ngā mea e toru i te mana whakahaere kounga hanga tūturu. Hei tāpiri, tirohia mēnā kei te pupuri tonu rātouISO 9001:2015te tiwhikete pūnaha whakahaere kounga me te mea kei te whai ā rātou whakamātautau i ngā paerewa e mōhiotia ana i te ao pēnei i ngā mea i whakaputaina e ASTM International.
