O le fa'ailoga fa'apipi'i fa'au'u fa'aigoa fa'aleaganu'u sa fa'aaogaina i le alamanuia HVAC mo le tele o tausaga.O u'amea na fa'aaogaina muamua fa'apa'apa apamemea lapotopoto ma apaapa alumini, ae o paipa apamemea na mafua ai le pala electrolytic ma anthill, ma o'o atu ai i le fa'ateleina o le ga'o, o le tala lea a Mark Lampe, o le pule o oloa mo u'aumu i le Carrier HVAC.Ina ia foia lenei faafitauli, ua liliu le alamanuia i paipa alumini lapotopoto faatasi ai ma fins alumini e faaleleia ai le faatinoga o faiga ma faaitiitia corrosion.O lea la ua iai le tekonolosi microchannel lea e mafai ona fa'aogaina i mea evaporators ma condenser.
"O le microchannel technology, ua taʻua o le VERTEX technology i Carrier, e ese mai i le mea lea e suitulaga ai paipa alumini lapotopoto i paipa tutusa mafolafola e faʻapipiʻi i apa alumini," o le tala lea a Lampe."O lenei mea e tufatufa atu ai le pusaaisa e sili atu ona tutusa i luga o se vaega lautele, faʻaleleia le faʻafefe o le vevela ina ia mafai ai e le coil ona galue lelei.A'o fa'aogaina le tekonolosi fa'ata'ita'i i totonu o fale fa'aputu i fafo, o le tekonolosi VERTEX o lo'o fa'aaogaina i le taimi nei i totonu o fale.
E tusa ai ma le saunoaga a Jeff Preston, le faatonu o auaunaga faʻapitoa i Johnson Controls, o le mamanu microchannel e faʻatupuina ai le faʻafefeteina e tasi-auala "i totonu ma fafo" o loʻo i ai se faʻamalo vevela i le pito i luga ma se paipa faʻafefe i lalo.I se fa'atusatusaga, o le mea fa'aaisa o lo'o i totonu o se fa'aili fa'au'u fa'au'u masani e tafe atu i le tele o alalaupapa mai luga i lalo i se mamanu gata, e mana'omia ai le tele o luga.
"O le mamanu faʻapitoa microchannel coil e maua ai le faʻaogaina lelei o le vevela, lea e faʻateleina ai le lelei ma faʻaitiitia ai le aofaʻi o le pusaaisa e manaʻomia," o le tala lea a Preston.“O le i'uga, o masini e fa'apipi'iina i microchannel coils e masani ona la'ititi nai lo masini fa'alelei maualuga fa'atasi ai ma mamanu fa'amau fa'aau.E fetaui lelei lea mo fa'aoga fa'aletonu avanoa e pei o fale e leai ni laina."
O le mea moni, faʻafetai i le faʻaofiina o tekinolosi microchannel, fai mai Lampe, ua mafai e le Carrier ona faʻatumauina le tele o pusa ogaumu i totonu ma fafo condensers ea malulu tutusa le lapoʻa e ala i le galue ma se faʻataʻitaʻiga lapotopoto ma faʻamau.
“Ana matou le fa'atinoina lea tekonolosi, semanu matou te fa'ateleina le tele o le ogaumu i totonu i le 11 inisi le maualuga ma semanu e tatau ona fa'aogaina se ta'avale lapo'a mo le condenser fafo," o lana tala lea.
E ui o le microchannel coil technology e masani ona faʻaaogaina i totonu o le pusaaisa i totonu o le fale, o le manatu ua amata ona maua i totonu o faʻalapotopotoga faʻapisinisi ona o loʻo faʻaauau pea ona faʻatupulaia le manaʻoga mo masini mama, sili atu le faʻapipiʻi, o le tala lea a Preston.
Talu ai ona o microchannel coils o loʻo i ai le laʻititi o le pusaaisa, e oʻo lava i ni nai aunese o le suiga o le tau e mafai ona aʻafia ai le ola, faʻatinoga ma le malosi o le malosi, o le tala lea a Preston.O le mea lea e tatau ai i konekarate ona siaki i taimi uma ma le gaosiga e uiga i le faʻagasologa o le totogiina, ae e masani ona aofia ai laasaga nei:
E tusa ai ma le Lampe, o le Carrier VERTEX tekinolosi e lagolagoina le seti tutusa, totogi ma le amataina o faiga e pei o le faʻaogaina o le faʻauʻu ma e le manaʻomia ni laasaga e faʻaopoopo pe ese mai le faʻataʻitaʻiga o loʻo fautuaina nei.
"E tusa ma le 80 i le 85 pasene o le tau o loʻo i totonu o le vai, o lea i le malulu o le voluma o loʻo i totonu o le condenser coil i fafo ma le pusa laina," o le tala lea a Lampe."Pe a agai i le microchannel coils ma le faʻaititia o le voluma i totonu (faʻatusatusa i mamanu tubular fin designs), o le eseesega i le tau e aafia ai naʻo le 15-20% o le tau atoa, o lona uiga o se fanua laʻititi, faigata-e fuaina le eseesega.O le mafuaaga lena o le auala fautuaina e totogi ai le masini e ala i le subcooling, auiliili i totonu o matou faʻatonuga faʻapipiʻi.
Ae ui i lea, o le itiiti ifo o le pusaaisa i totonu o microchannel coils e mafai ona avea ma faʻafitauli pe a sui le pusa vevela i fafo i le faʻamafanafanaina, o le tala lea a Lampe.I lenei faiga, o le system coil ua fesuiai ma o le capacitor e teuina le tele o le tau o le suavai ua avea nei ma coil totonu.
"Afai o le tele o totonu o le vili totonu e matua itiiti ifo nai lo le vili fafo, e mafai ona tupu se le paleni o le tau i totonu o le masini," o le tala lea a Lampe."Ina ia foia nisi o nei faʻafitauli, e faʻaaogaina e le Carrier se maa faʻapipiʻi i totonu o le iunite i fafo e faʻafefe ma teu ai le tele o le tau ile faʻavevela.O lenei mea e mafai ai e le faiga ona faʻamautu lelei le mamafa ma puipuia ai le compressor mai lologa, lea e mafai ona oʻo atu ai i le le lelei o le faʻatinoga ona o le suauʻu e mafai ona faʻatupu i totonu o le vili totonu.
A'o fa'atonuina se faiga i microchannel coils e mafai ona mana'omia le gauai fa'apitoa i auiliiliga, o le fa'atonuina o so'o se HVAC system e mana'omia le fa'aoga sa'o o le aofa'i sa'o o le pusaaisa, fai mai Lampe.
"Afai e mamafa tele le faiga, e mafai ona oʻo atu ai i le faʻaaogaina o le eletise maualuga, le lelei o le malulu, faʻafefe ma le vave o le compressor," o lana tala lea.“E fa'apena fo'i, afai e le'i totogia le fa'aogaina, fa'amalo fa'aisa, fa'alauteleina valve vibration, fa'afitauli amata o le compressor ma tapuni sese e mafai ona tupu.O faʻafitauli i microchannel coils e leai se faʻalavelave."
E tusa ai ma le saunoaga a Jeff Preston, le faatonu o auaunaga faʻapitoa i Johnson Controls, o le toe faaleleia o microchannel coils e mafai ona luitauina ona o la latou mamanu tulaga ese.
“E mana'omia le fa'amea i luga ole laiga ma sulu kasa MAPP e le masani ona fa'aogaina i isi ituaiga masini.O le mea lea, o le tele o konekarate o le a filifili e sui vili nai lo le taumafai e toe faaleleia.
A o'o mai i le fa'amamāina o vili microchannel, e matua faigofie lava, o le tala lea a Mark Lampe, le pule o oloa mo fa'a'umu umu i le Carrier HVAC, ona e faigofie lava ona lolo'u apa'apa alumini o fa'au'u fa'apa'u.O le tele naua o apa fa'apipi'i o le a fa'aitiitia ai le aofa'i o le ea e ui atu i le u'amea, fa'aitiitia ai le lelei.
“O le tekonolosi VERTEX o le Carrier VERTEX o se mamanu sili atu ona malosi aua o le alumini alumini e nofo laʻititi i lalo ole paʻu alumini mafolafola ma faʻapipiʻi i paipa, o lona uiga o le pulumu e le suia tele ai apaapa," o le tala lea a Lampe.
Fa'amama Faigofie: Pe a fa'amama fa'avili microchannel, fa'aaoga na'o mea mama, e le o ni fa'a'asa'o fa'amama pe, i le tele o tulaga, na'o le vai.(tuuina atu e le ave taavale)
Pe a fa'amama vili fa'avili microchannel, fai mai Preston 'alo ese vaila'au malolosi ma fufulu fa'amalosi, ae fa'aaoga na'o mea mama, e le'o fa'asa'o mama pe, i le tele o tulaga, na'o le vai.
"Ae ui i lea, o sina vaega itiiti o le pusaaisa e manaʻomia ai ni fetuunaiga i le faagasologa o le tausiga," o lana tala lea."Mo se faʻataʻitaʻiga, ona o le laʻititi, e le mafai ona pamu i fafo le pusaaisa pe a manaʻomia e isi vaega o le masini le tautua.E le gata i lea, e tatau ona faʻafesoʻotaʻi le laulau meafaigaluega pe a manaʻomia e faʻaitiitia ai le faʻalavelaveina o le voluma pusaaisa.
Na faʻaopopo e Preston o Johnson Controls o loʻo faʻaogaina tulaga ogaoga i lona fanua faʻamaonia Florida, lea na faʻaosofia ai le atinaʻeina o microchannels.
"O taunuuga o nei suʻega e mafai ai ona tatou faʻaleleia atili le atinaʻeina o oloa e ala i le faʻaleleia atili o uʻamea, mafiafia paipa ma le faʻaleleia o kemisi i le faʻaogaina o le atemosifia faʻafefeteina e faʻatapulaʻa ai le pala ma faʻamautinoa le maualuga o le faʻatinoga ma le faʻamaoni e ausia," o lana tala lea."O le faʻaaogaina o nei faiga o le a le gata ina faʻamalieina ai le tagata e ona le fale, ae o le a fesoasoani foi i le faʻaitiitia o manaʻoga tausiga."
