Igikoko c'umuringa c'umuringa gifise Urutonde rw'Isubiriza y'Ibarabara ry'Ibarabara
Ivyo bikoresho vyagenewe canecane ugusubirira ibikoresho vya kera vy’ubushuhe, uru rutonde rukoresha ubuhinga bwose bwo gusudira, bikaba bishiramwo amababa afise imirongo isongoye. Ubushobozi bwo gutanga ubushuhe buragwira n’ibice birenga 42%, bibereye amafiriji asanzwe nka R134a na R404A, akoreshwa cane mu bikoresho vy’ubudandaji vy’ubudandaji, akagaragaza ama kabine, n’ibindi.
Gukoresha uburyo n'ugutuma ibintu biguma hasi.
Ishobora gukoreshwa mu kirere - ivyabaye, n’uburebure bwa 16-25mm, ubushobozi bwo guhangana n’umuyaga buragabanywa n’ibice 31%. Ni vyiza cane cane ku bikoresho vyo gukonjesha bishizwemwo n’amamashini mato mato yo gukora urubura, kandi birafasha gukoresha neza ibikoresho bidasanzwe bishobora gukayangana nk’ivyo bita R290.

Uko woguma ufise Ibice vy'Imirongo y'Imirongo y'Abantu ku Buzima bw'Ibikorwa

Ivyuma vy’ivyuma vy’ivyuma (igice nyamukuru c’ibikoresho vy’ugukonja) bifise umurongo w’ivyuma vy’aluminium ufise ivyuma vy’ivyuma vy’ivyuma vy’ivyuma, imirongo y’amazi y’urugero rwa microple mm (0.1–2 mm), n’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma. Ugutunganirizwa neza ni ikintu gihambaye cane mu kuzigama ubutungane bwavyo bw’imiterere, ubushobozi bwo gutanga ubushuhe, n’ugushobora guhangana n’ugusenyuka- ibintu nyamukuru vyo kwagura ubuzima bw’ibikoresho vy’ubushuhe bw’imirongo mito (MHEs). Aha hepfo hariho ubuyobozi burambuye bujanye n'imigenzo y'ingenzi n'amajambo ya MCHE- yihariye:

1. Gusukura ubudasiba: Gukingira Ubushuhe Guhindura

Ivyuma vy’amazi n’imigende y’amazi y’amazi n’imigende y’amazi bishobora gupfunyika biciye ku nkungugu, umwanda canke ibisigarira vy’amavuta y’ibitoke, ivyo bikaba bigabanya uburebure bw’uburebure bw’ubushuhe no kwongera ugutemba kw’umuvuduko.

Gusukura neza:Ikoresha hasi - Umukanda ( Ukekeranya kuruta canke ungana na 300 psi) igipimo c'ivyuma canke igikoresho co gushaza - carstle kugira ngo ukureho ibisigazwa vy'amazi biva ku mafi y'umukara. Ku bijanye n’ibisigazwa vy’ibintu (nk’akarorero, amavuta, urugero), koresha ibikoresho vyo gusukura pH bitagira aho bihuriye (bizigamire imiti y’aside/alkaline yononekaye mu microchannels) no gusukura amazi afise ioni. Ufungure igiti c’ibande neza kugira ngo ntihagire ubukonje.Inyishu: Irinde cane - indege y'amazi y'amazi- ishobora gupfukama canke yononekaye ibipimo vy'imirongo mito mito, bihungabanya uruja n'uruza rw'umuyaga n'uguhindura ubushuhe.

Umugozi w'imbere mu gihugu:Inyuma y'umurongo w'inzira y'amazi n'igikoresho co gusukura (nk'akarorero, polyol ester- ishingiye ku bikoresho vya R134a/R410A) kugira ngo ikuremwo amavuta canke oxide. Gucungera igipimo c’uruja n’uruza rw’amazi ( Less kuruta canke angana na 10 L/min) kugira ngo umukazo urenze urugero ntiwononekare -

2. Gukingira umuzigo: Aluminiyumu Aluminiyumu Safeguard

Aluminium, ikintu nyamukuru c’ivyuma vya MCHE, ni co gishobora gufatwa n’ugusenyuka (kuva mu bukonje, umunyu- umuyaga, canke ibintu bihumanya aside). Uburinzi bw’ibikorwa ni ngombwa:

Gutegura ibintu:Nusuzume ivy’inyuma birwanya {{0}== igipfukisho c’imbere (nk’akarorero, igihimba c’umubiri c’umubiri, epoxy, canke fluoropolymer). Kora ahantu hashizweko canke hashizweko igipande c’imbere gifise - Uburyo bwo gutera - bushobora kubaka (uburemere bwa filime yumye: 20–50 μm) kugira ngo udome ibipande vy’aluminium vyashizwe ahabona. Ku bikoresho vy’ugukonja mu bice vyo ku nkengera y’ikiyaga, koresha ibindi bipande vy’imiti irwanya - y’umunyu ku mwaka.

Gucungera amazi:Niwishingire ko igitereko c’amazi y’umukogonda kidapfutse kugira ngo amazi ahagaze areke gutonyanga ku nzira y’umutobe. Shiraho igikoresho co gukuraho ubukonje mu cumba c’ibikoresho iyo ubukonje burenze 60%- ubukonje bwinshi burahutisha ugusenyuka kw’imitsi y’umubiri hagati y’imirongo y’ivyuma n’imirongo y’ifiriji y’umuringa.

Abarinzi b'ibisebe:Rwongerako ibibuza uruzitiro rw’amazi (ku bijanye n’amazi- Igikoresho co gukonjesha amazi) kugira ngo ntihagire uguhingura urugero n’ivyuma vy’ivyuma. Hitamwo ibibuza bidafise -

3. Gukuraho: Uzigabire Inkomezi- Ivyanyu

Ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma.

Igerageza ry'Ivyiyumviro vy'Inguvu:Igerageza ry’ugusohoka kw’amazi y’umubiri (ugutahura ibintu: Ukenerwa canke ungana na 1×10⁻⁻ Pa·m3/s) igice c’amahuzu yose y’ifeza n’ibice vy’umubiri. Ku bikoresho bininibinini, koresha igikoresho co gutahura helium gishobora gutwara kugira ngo ushiremwo imitwe microchannel n’ivyuma vy’ivyuma vy’ibara ry’agahama - kwibanda ku bice bishobora gutera imibabaro y’ubushuhe (nk’akarorero, hafi y’ivyuma vy’ivyuma).

Igerageza ry'Igiharuro:Monthly perform a pressure decay test on the refrigerant circuit: Charge the system with dry nitrogen (pressure: 1.5× the design working pressure, typically 2–3 MPa) and monitor for pressure drops over 24 hours. A drop >0.01 MPa yerekana ko hariho ukuvuza bisaba gusanurwa (nk’akarorero, re- gukuraho utugingo ngengabuzima dutoduto canke gusubirira utugingo ngengabuzima dusongoye).

4. Gukurikirana ibikorwa: Kwirinda cane n'igihe c'ubushuhe

Gukora neza cane (nk’akarorero, ubushuhe burengeje urugero, uguhinduka kw’urugero rw’uruja n’uruza) bituma ubushuhe buhungabana ku mibumbe mito mito, bigatuma habaho urushe rw’ingingo canke umutsi w’umubiri.

Gukurikirana neza ivy'ingenzi:Gukurikirana neza:

Ubushuhe bw'Ivyiyumviro: Gukomeza Bike kuruta canke bingana n’ivyo 55 (ku mirongo ya R134a) kugira ngo wirinde gushuha cane umurongo w’aluminiyumu- Ubushuhe bwinshi buragoyagoya ubusa- Imipaka y’amabuye y’agaciro.

Umukazo w'Ikanguruzo: Monitor the refrigerant side pressure drop across the microchannel core; a sudden increase (>20% vy’intango) vyerekana ko umurongo w’amazi uhagarara.

Inyama: Kubungabunga ibiharuro vy’amazi/umuyaga (wirinde ugutera imbere kw’amazi) kugira ngo amazi agende, ivyo bikaba bishobora kugira ico bikoze no kwonona ivyuma vy’amazi.

Irinde Gufata -Igice c'Imbeho: Iyo umunyu ufunze (nk’akarorero, kugira ngo umuntu ayibungabunge), aguma afise umugozi w’ifiriji mu gipimo ciza ( kinini canke kingana na 0.1 MPa) n’azote yumye kugira ngo umuyaga w’umutobe winjire mu microchannels-moistique ikora n’amavuta y’ifi kugira ngo akore aside zisukuye.

5. Uburyo bwiza bwo gutunganya ibintu: Gukingira Imigezi y'amashini

Ivyuma vy'ubuhinga bwa none (biciye ku nzira zisongoye, amababa agaragara) birashobora gushikirwa n'ingaruka z'ubuhinga- Gukora neza ni ikintu gihambaye cane:

Guteza imbere/gukorana n'abandi: Iyo umuntu ashobora gushika ku gikoresho co guterura, ukoreshe ibikoresho bikwiye vyo guterura (nk’akarorero, ivyuma bipfutse) kugira ngo wirinde gupfukama canke gumenagura amababa make. Ntukigere ushira ibintu biremerera ku nzira ya MCHE, kuko ivyo bishobora guhindura inzira z’uruja n’uruza rw’imbere.

Igenzura ry'Ugushakashaka:Mbega suzuma neza ubutungane bw'ibipfukisho vyo gushiramwo n'uguhungabana kw'ibintu vy'uguhungabana- ingufu zituma umugozi mutoyi uhungabana, ugatuma haba urushe mu ngingo zipfutse mu gihe c'igihe. Gufatanya n’ivyo umuhinguzi afatanya n’umuvuduko w’umuhinguzi (mu bisanzwe 8–12 N·m ku bijanye n’ivyuma vy’aluminium).

Inguvu z'umwuga:Ku bijanye n’ugusanura gukomeye (nk’akarorero, gusubirira imirongo y’imirongo y’amazi yononekaye, re- ituma umuntu agira ubwoba), ukoreshe abahinga bamenyerejwe mu bijanye no gusanasana MCHE. Guca ibibatsi ku buryo butabereye birashobora kubuza amashini mato mato canke gutuma haba ingingo zigoyagoya, bikagabanya ubuzima bw’umukondenser.

Mu kwibanda ku gusukura ubudasiba, gukingira ugusenyuka, kumenya amazi, kugenzura ibikorwa, no gukora neza, urashobora kwagura cane ubuzima bw’ibikoresho vy’ubuhinga bwa none mu bikoresho vy’ugukonja- Mu buryo bw’ubuhinga kuva ku myaka 8–10 gushika ku myaka 12–15. Ivyo bikorwa ntibizigama gusa ibihimba vya MCHE (umurongo w’aluminium, ubusa- ingingo z’uruzitiro, imirongo y’uruja n’uruza rw’urugero ruto) ariko kandi zigatuma ubushuhe buguma bukora neza, bikagabanya ibiciro vy’ibikorwa vy’ubuhinga bwa none.

Imisoro ishushe: micro- Igikoresho co guhindura ivyuma, Ubushinwa- ibikoresho vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma, abagurisha, uruganda
