Igishushanyo mbonera cyateguwe neza ni cyo gipimo gikoreshwa mu nganda za HVAC imyaka myinshi.Mark Lampe, umuyobozi w’ibicuruzwa by’amashyiga muri Carrier HVAC, avuga ko ayo mashanyarazi yabanje gukoresha umuyoboro w’umuringa uzengurutswe na aluminiyumu, ariko umuyoboro w’umuringa wateje ruswa ya electrolytike na anthill, bigatuma imyanda yiyongera.Kugira ngo iki kibazo gikemuke, inganda zahinduye umuyoboro wa aluminiyumu hamwe na aluminiyumu kugirango tunoze imikorere ya sisitemu kandi ugabanye ruswa.Ubu hariho tekinoroji ya microchannel ishobora gukoreshwa haba mumashanyarazi hamwe na kondenseri.
Lampe yagize ati: "Ikoranabuhanga rya microchannel, ryitwa tekinoroji ya VERTEX muri Carrier, riratandukanye kubera ko umuyoboro wa aluminiyumu uzunguruka usimbuzwa imiyoboro iringaniye igurishwa ku bicuruzwa bya aluminium."Ati: “Ibi bikwirakwiza firigo mu buryo bwagutse ahantu hanini, bigateza imbere ubushyuhe kugirango igiceri gikore neza.Mu gihe ikoranabuhanga rya microchannel ryakoreshwaga mu cyumba cyo guturamo cyo hanze, ubu tekinoroji ya VERTEX ikoreshwa gusa mu bikoresho byo guturamo. ”
Nk’uko byatangajwe na Jeff Preston, umuyobozi wa serivisi tekinike muri Johnson Controls, igishushanyo mbonera cya microchannel gikora umuyoboro woroheje wa firigo “winjira kandi usohoka” ugizwe n'umuyoboro ushyushye hejuru hamwe n'umuyoboro wa subcoled hepfo.Ibinyuranyo, firigo muburyo busanzwe bwa coil yamashanyarazi inyura mumiyoboro myinshi kuva hejuru kugeza hasi muburyo bwinzoka, bisaba ubuso bunini.
Preston yagize ati: "Igishushanyo cyihariye cya microchannel coil itanga coefficient nziza yo kohereza ubushyuhe, byongera imikorere kandi bikagabanya umubare wa firigo ukenewe".Yakomeje agira ati: “Kubera iyo mpamvu, ibikoresho byakozwe na mikorobe ya mikorobe akenshi usanga ari bito cyane ugereranije n’ibikoresho bikora neza kandi bikozwe mu buryo bwa gakondo.Ibi ni byiza kuri porogaramu zidafite umwanya nk'amazu afite imirongo ya zeru. ”
Lampe avuga ko mu byukuri, bitewe n’ikoranabuhanga rya mikorobe ikoreshwa, Carrier yashoboye kugumana ibicanwa byinshi byo mu itanura ryo mu nzu hamwe n’icyuma gifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata imashini.
Ati: "Niba tutarashyize mu bikorwa iryo koranabuhanga, twagombaga kongera ubunini bw'ifuru y'itanura ry'imbere kugeza kuri santimetero 11 z'uburebure kandi byabaye ngombwa ko dukoresha chassis nini kuri kanseri yo hanze".
Preston yavuze ko mu gihe ikoranabuhanga rya microchannel rikoreshwa cyane cyane mu gukonjesha mu ngo, igitekerezo gitangiye gufata mu bucuruzi mu gihe hakenewe ibikoresho byoroheje, byoroheje bikomeza kwiyongera.
Preston avuga ko kubera ko ibishishwa bya microchannel birimo bike bya firigo, ndetse na garama nkeya zahinduwe zishobora kugira ingaruka kubuzima bwa sisitemu, imikorere ndetse ningufu zingirakamaro.Niyo mpamvu abashoramari bagomba guhora bagenzura nuwabikoze kubyerekeye uburyo bwo kwishyuza, ariko mubisanzwe birimo intambwe zikurikira:
Nk’uko Lampe abitangaza ngo tekinoroji ya Carrier VERTEX ishyigikira uburyo bumwe bwo kwishyiriraho, kwishyuza no gutangiza kimwe n’ikoranabuhanga rya tekinike kandi ntibisaba intambwe ziyongera cyangwa zitandukanye n’uburyo busabwa bwo gukonjesha.
Lampe yagize ati: "Hafi ya 80 kugeza 85 ku ijana by'amafaranga yishyurwa ari mu mazi, ku buryo mu buryo bwo gukonjesha iyo mibumbe iri mu giceri cyo hanze ndetse no mu murongo.""Iyo wimukiye kuri microchannel coil hamwe nigabanuka ryimbere ryimbere (ugereranije nigishushanyo mbonera cya tubular fin), itandukaniro ryishyurwa rireba 15-20% gusa yumushahara wose, bivuze ko ari ntoya, igoye-gupima ikinyuranyo.Niyo mpamvu inzira isabwa yo kwishyuza sisitemu ari ugukonjesha, birambuye mu mabwiriza yo kwishyiriraho. ”
Lampe yavuze ko, ariko, frigo nkeya muri firigo ya microchannel irashobora kuba ikibazo mugihe ishami rya pompe yubushyuhe bwo hanze ryahinduye uburyo bwo gushyushya.Muri ubu buryo, coil ya sisitemu yarahinduwe kandi capacitor ibika igice kinini cyamazi ni coil imbere.
Lampe yagize ati: "Iyo ingano y'imbere ya coil yo mu nzu iri munsi cyane ugereranije n'iy'igiceri cyo hanze, ubusumbane bw'amafaranga bushobora kugaragara muri sisitemu."Ati: “Kugira ngo bikemure bimwe muri ibyo bibazo, Carrier ikoresha bateri yubatswe iri mu gice cyo hanze kugira ngo ikure kandi ibike amafaranga arenze mu buryo bwo gushyushya.Ibi bituma sisitemu igumana umuvuduko ukwiye kandi ikabuza compressor umwuzure, ibyo bikaba bishobora gutuma imikorere idahwitse kuko amavuta ashobora kwiyongera muri coil imbere. ”
Lampe avuga ko mu gihe kwishyuza sisitemu ifite ibiceri bito bishobora gusaba kwitabwaho bidasanzwe, kwishyuza sisitemu iyo ari yo yose ya HVAC bisaba gukoresha neza urugero rwa firigo.
Ati: "Niba sisitemu iremerewe cyane, irashobora gutuma hakoreshwa ingufu nyinshi, gukonjesha kudakora neza, kumeneka no kunanirwa na compressor imburagihe".Ati: "Muri ubwo buryo, niba sisitemu idahagije, gukonjesha ibishishwa, kwaguka kwa valve kwinyeganyeza, compressor itangira ibibazo no guhagarika ibinyoma birashobora kubaho.Ibibazo bifite ibiceri bito bito na byo ntibisanzwe. ”
Nk’uko byatangajwe na Jeff Preston, umuyobozi wa serivisi tekinike muri Johnson Controls, gusana ibiceri bito bishobora kugorana kubera imiterere yihariye.
Ati: "Kugurisha hejuru bisaba amavuta ya gaz na MAPP adakoreshwa mubindi bikoresho.Kubera iyo mpamvu, abashoramari benshi bazahitamo gusimbuza ibiceri aho kugerageza gusana. ”
Mark Lampe, umuyobozi w’ibicuruzwa bikozwe mu itanura muri Carrier HVAC, avuga ko ku bijyanye no guhanagura ibiceri bito bito, mu byukuri biroroshye.Ibinini byinshi bigoramye bizagabanya ubwinshi bwumwuka unyura muri coil, bigabanye imikorere.
Lampe yagize ati: "Ikoranabuhanga rya Carrier VERTEX ni igishushanyo gikomeye kubera ko amababa ya aluminiyumu yicaye munsi gato ya firigo ya firigo ya aluminiyumu kandi igashyirwa ku miyoboro, bivuze ko gukaraba bidahindura amababa ku buryo bugaragara."
Isuku yoroshye: Mugihe cyoza ibishishwa bya microchannel, koresha gusa isuku yoroheje, idafite aside irike cyangwa, akenshi, amazi gusa.(yatanzwe nuwitwaye)
Mugihe cyoza ibishishwa bya microchannel, Preston avuga ko irinda imiti ikaze no gukaraba igitutu, ahubwo ukoreshe gusa ibikoresho byoroheje, bidafite aside irike cyangwa, akenshi, amazi gusa.
Ati: "Icyakora, firigo nkeya isaba ko hagira ibyo uhindura mubikorwa byo kubungabunga".Ati: “Urugero, kubera ubunini buto, firigo ntishobora kuvomwa mugihe ibindi bice bigize sisitemu bikeneye serivisi.Byongeye kandi, akanama k'ibikoresho kagomba guhuzwa gusa igihe bibaye ngombwa kugira ngo hagabanuke ihungabana ry'ubunini bwa firigo. ”
Preston yongeyeho ko Johnson Controls irimo gukoresha ibihe bikabije kuri Floride yerekana, ibyo bikaba byaratumye iterambere rya mikorobe ritera imbere.
Ati: "Ibyavuye muri ibi bizamini bidufasha kuzamura iterambere ry’ibicuruzwa byacu tunoza amavuta menshi, umubyimba w’imiyoboro hamwe n’imiti ya chimisti mu buryo bwo kugenzura ikirere cyagenzuwe kugira ngo igabanye ruswa kandi tumenye ko imikorere myiza kandi yizewe igerwaho".“Iyemezwa ry'izi ngamba ntirizongera gusa kunyurwa na nyir'inzu, ahubwo rizafasha no kugabanya ibikenerwa mu kubungabunga.”
