304 / 304L ibyuma bya chimique idafite ibyuma Ikintu cyose ukeneye kumenya kuri HVAC Capillaries Igice cya 1 |2019-12-09

Disipanseri ya capillary ikoreshwa cyane cyane mubikorwa byimbere mu gihugu no mu bucuruzi buto aho ubushyuhe bwumuriro kuri moteri bihoraho.Izi sisitemu kandi zifite umuvuduko muke wa firigo kandi mubisanzwe ukoresha compressor ya hermetic.Ababikora bakoresha capillaries kubera ubworoherane bwabo nigiciro gito.Mubyongeyeho, sisitemu nyinshi zikoresha capillaries nkigikoresho cyo gupima ntizisaba kwakirwa kuruhande rwo hejuru, bikagabanya ibiciro.

304 / 304L ibyuma bitarimo ibyuma

Imiyoboro ya capillary ntakindi kirenze umuyoboro muremure wa diameter ntoya hamwe nuburebure bwagenwe bwashyizwe hagati ya kondereseri na moteri.Capillary mubyukuri ipima firigo kuva kondenseri kugeza kumashanyarazi.Bitewe n'uburebure bunini na diameter ntoya, iyo firigo inyuzemo, guterana amazi no kugabanuka k'umuvuduko.Mubyukuri, mugihe amazi arenze urugero atemba ava munsi ya kondenseri anyuze muri capillaries, amwe mumazi ashobora guteka, akagira ibyo bigabanuka.Ibitonyanga byumuvuduko bizana amazi munsi yumuvuduko wuzuye mubushyuhe bwayo ahantu henshi kuruhande rwa capillary.Uku guhumbya guterwa no kwaguka kwamazi iyo umuvuduko ugabanutse.
Ubunini bwa flash yamashanyarazi (niba ihari) bizaterwa nubunini bwa subcooling yamazi ava muri kondenseri na capillary ubwayo.Niba flashing yamashanyarazi ibaye, hifujwe ko flash iba hafi ya moteri ishoboka kugirango tumenye neza imikorere ya sisitemu.Ubukonje bukabije amazi ava hepfo ya kondenseri, amazi make yinjira muri capillary.Ubusanzwe capillary iratondekwa, ikanyuzwa cyangwa igasudwa kumurongo wo guswera kugirango hongerwemo subcooling kugirango wirinde amazi yo muri capillary guteka.Kuberako capillary igabanya kandi igapima umuvuduko wamazi kuri moteri, ifasha kugumana umuvuduko ukenewe kugirango sisitemu ikore neza.
Umuyoboro wa capillary na compressor nibintu bibiri bitandukanya uruhande rwumuvuduko mwinshi kuruhande rwumuvuduko muke wa sisitemu yo gukonjesha.
Umuyoboro wa capillary utandukanye nigikoresho cyo gupima ubushyuhe bwa termostatike (TRV) kubera ko kidafite ibice byimuka kandi ntigenzura ubushyuhe bukabije bwumuyaga mubihe byose byubushyuhe.Ndetse mugihe habuze ibice byimuka, imiyoboro ya capillary ihindura umuvuduko mugihe umuvuduko wa / cyangwa kondereseri ya sisitemu ihinduka.Mubyukuri, igera gusa kubikorwa byiza mugihe imikazo kuruhande rwo hejuru no hasi ihujwe.Ni ukubera ko capillary ikora ikoresha itandukaniro ryumuvuduko hagati yumuvuduko mwinshi kandi muto wa sisitemu yo gukonjesha.Mugihe itandukaniro ryumuvuduko hagati yimpande ndende na ntoya ya sisitemu yiyongera, umuvuduko wa firigo uziyongera.Imiyoboro ya capillary ikora neza kuburyo butandukanye bwigitutu cyumuvuduko, ariko mubisanzwe ntabwo ikora neza.
Kubera ko capillary, evaporator, compressor na condenser bihujwe murukurikirane, umuvuduko wogutemba muri capillary ugomba kuba uhwanye na pompe yihuta ya compressor.Niyo mpanvu uburebure bwabazwe na diameter ya capillary kuri comptabilite yabazwe hamwe ningutu ya kondegene irakomeye kandi igomba kuba ingana nubushobozi bwa pompe mubihe bimwe.Impinduka nyinshi muri capillary zizagira ingaruka kumurwanya wacyo hanyuma bigire ingaruka kuburinganire bwa sisitemu.
Niba capillary ari ndende cyane kandi ikarwanya cyane, hazabaho kubuza gutembera kwaho.Niba diameter ari nto cyane cyangwa haribintu byinshi cyane iyo ihindagurika, ubushobozi bwigituba buzaba munsi yubwa compressor.Ibi bizavamo kubura amavuta mumashanyarazi, bikavamo umuvuduko muke hamwe nubushyuhe bukabije.Muri icyo gihe, amazi akonje azasubira muri kondenseri, arema umutwe muremure kuko nta sisitemu yakira muri sisitemu yo gufata firigo.Hamwe n'umutwe muremure hamwe n'umuvuduko muke muri moteri, umuvuduko wa firigo uziyongera kubera umuvuduko mwinshi ugabanuka hejuru ya capillary.Mugihe kimwe, imikorere ya compressor izagabanuka bitewe nigipimo kinini cyo guhunika hamwe nubushobozi buke bwo hasi.Ibi bizahatira sisitemu kuringaniza, ariko kumutwe muremure hamwe nigitutu cyo hasi cyuka gishobora gutuma habaho imikorere idakenewe.
Niba kurwanya capillary bitarenze ibyo bisabwa kubera diameter ngufi cyangwa nini cyane, umuvuduko wa firigo uzaba urenze ubushobozi bwa pompe compressor.Ibi bizavamo umuvuduko mwinshi wumuyaga, ubushyuhe buke hamwe na compressor zishobora kuba umwuzure kubera kugabanuka kwinshi.Subcooling irashobora kugabanuka muri kondenseri itera umuvuduko muke wumutwe ndetse no gutakaza kashe ya mazi hepfo ya kondenseri.Uyu mutwe muto kandi urenze umuvuduko usanzwe wumuyaga bizagabanya igipimo cyo kwikuramo compressor bivamo gukora neza cyane.Ibi bizongera ubushobozi bwa compressor, irashobora kuringanizwa mugihe compressor ishobora gutwara firigo nyinshi muri moteri.Akenshi firigo yuzuza compressor, kandi compressor ntishobora kwihanganira.
Kubwimpamvu zavuzwe haruguru, ni ngombwa ko sisitemu ya capillary ifite amafaranga ya firigo yuzuye (ikomeye) muri sisitemu yabo.Firigo nyinshi cyangwa nkeya irashobora gukurura ubusumbane bukabije no kwangirika gukomeye kuri compressor kubera gutemba kwamazi cyangwa umwuzure.Kugirango ubunini bukwiye bwa capillary, baza uwabikoze cyangwa reba imbonerahamwe yubunini.Icyapa cya sisitemu cyangwa icyapa cya sisitemu bizakubwira neza umubare wa firigo sisitemu ikenera, mubisanzwe muri kimwe cya cumi cyangwa ijana cyama une.
Kumashanyarazi menshi yubushyuhe, sisitemu ya capillary mubisanzwe ikorana nubushyuhe bukabije;mubyukuri, ubushyuhe bukabije bwa 40 ° cyangwa 50 ° F ntibisanzwe mubisanzwe ubushyuhe bwinshi.Ni ukubera ko firigo iri mumyuka ihumeka vuba kandi ikazamura 100% byuzuyemo umwuka mubyuka, bigaha sisitemu gusoma cyane.Imiyoboro ya capillary ntabwo ifite uburyo bwo gutanga ibitekerezo, nkumucyo wa kure wa termostatike (TRV) urumuri rwa kure, kugirango ubwire igikoresho cyo gupima ko gikora kuri superheat nyinshi kandi gihita gikosora.Kubwibyo, iyo umutwaro uhumeka ari mwinshi hamwe nubushyuhe bukabije bwa moteri, sisitemu izakora neza cyane.
Ibi birashobora kuba bimwe mubibi byingenzi bya sisitemu ya capillary.Abatekinisiye benshi bifuza kongeramo firigo nyinshi muri sisitemu kubera gusoma cyane, ariko ibi bizarenza sisitemu.Mbere yo kongeramo firigo, genzura ibisomwa bisanzwe mubisanzwe hejuru yubushyuhe buke.Iyo ubushyuhe buri mu mwanya wa firigo bugabanutse ku bushyuhe bwifuzwa kandi umwuka uhumeka uri munsi yubushyuhe buke, ubushuhe busanzwe bwa moteri bugera kuri 5 ° kugeza 10 ° F.Mugihe ushidikanya, kusanya firigo, kura sisitemu hanyuma wongereho amafaranga akomeye ya firigo yerekanwe kurupapuro.
Iyo ubushyuhe bwinshi bumaze kugabanuka kandi sisitemu igahinduka mubushyuhe buke bwo guhumeka, imyuka ihumeka 100% izagabanuka hejuru yinzira zanyuma za moteri.Ibi biterwa nigabanuka ryikigereranyo cyuka cya firigo muri moteri kubera ubushyuhe buke.Ubu sisitemu izaba ifite ubushyuhe busanzwe bwa 5 ° kugeza 10 ° F.Ibi bisomwa bisanzwe bya superheat bizashoboka gusa mugihe ubushyuhe bwumuriro buri hasi.
Niba sisitemu ya capillary yuzuye, izegeranya amazi arenze muri kondenseri, bigatera umutwe muremure kubera kubura imashini muri sisitemu.Kugabanuka k'umuvuduko hagati yumuvuduko muke kandi mwinshi wa sisitemu uziyongera, bigatuma umuvuduko wo gutembera kumyuka wiyongera kandi ibyuka bikarenza urugero, bikavamo ubushyuhe bukabije.Irashobora no kwuzura cyangwa gufunga compressor, niyindi mpamvu ituma sisitemu ya capillary igomba kwishyurwa byimazeyo cyangwa neza neza na frigo yagenwe.

Ibirimo Biterwa inkunga ni igice cyihariye cyishyuwe aho amasosiyete yinganda atanga ubuziranenge, butabogamye, butari ubucuruzi ku ngingo zishimishije abumva amakuru ya ACHR.Ibintu byose byatewe inkunga bitangwa namasosiyete yamamaza.Ushishikajwe no kwitabira igice cyatewe inkunga?Menyesha uwuserukira.
Kubisabwa Muri uru rubuga, tuziga kubyerekeye ibishya bigezweho kuri firigo ya R-290 nuburyo bizagira ingaruka ku nganda za HVACR.
Muri uru rubuga, abavuga Dana Fisher na Dustin Ketcham baganira ku buryo abashoramari ba HVAC bashobora gukora ubucuruzi bushya kandi bagasubiramo bafasha abakiriya gukoresha inguzanyo z’imisoro ya IRA n’ubundi buryo bwo gushyiraho pompe z’ubushyuhe mu bihe byose.
