Microchannel Condenser Ibicuruzwa bikurikirana
Gakondo y'umuringa hamwe na plaque yarangije gushyushya ibyiciro byo gusimbuza
Byashizweho byumwihariko kugirango bisimbuze ubushyuhe busanzwe bwa plaque yubushyuhe, uru rukurikirane rukoresha tekinoroji ya - ya aluminiyumu yo gusudira, ihuza udusimba hamwe na tebes. Gukwirakwiza ubushyuhe byiyongereyeho hejuru ya 42%, bikwiranye na firigo zisanzwe nka R134a na R404A, zikoreshwa cyane muri firigo zubucuruzi, kwerekana akabati, nibindi.
Gukonjesha no gukonjesha Hasi - Urukurikirane rwo hejuru
Gukwirakwiza umwanya - ibintu byagabanijwe, hamwe nubunini bwa 16 - 25mm, kurwanya umuyaga bigabanukaho 31%. Irakwiriye cyane cyane ibikoresho byo gukonjesha byashyizwemo hamwe n’imashini ntoya ikora urubura, kandi ishyigikira ikoreshwa ryiza rya firigo zaka umuriro nka R290.
Urugo / Urutonde rwumusaruro rusange
Ibicuruzwa bisanzwe byabyaye umusaruro, hamwe nigitutu cyashushanyije kigera kuri 3.5MPa, hejuru yuzuyeho AL0, igorofa - irwanya ruswa, ikamara igihe kirenze imyaka 10, ikaba ikeneye ibikoresho bingana - nkibikoresho bikonjesha hamwe nogutwara imbeho ikonje.
Urutonde rwihariye rwihariye
Byashizweho byumwihariko kubikoresho byamazi yinganda / byumye bikonje, uru ruhererekane rugizwe na microchannel itoboye itubutse - igishushanyo mbonera, hamwe no kugabanya 50% ingano yuzuye, bikwiranye na firigo zose usibye CO, byujuje ibisabwa - byangirika byumuvuduko ukabije wa sisitemu ikurikirana.

Nigute Wokomeza Kuringaniza Microchannel muri Chillers Kubuzima Bwagutse bwa Serivisi
Imiyoboro ya Microchannel (igice cyibanze cya chillers) igaragaramo intungamubiri ya aluminiyumu hamwe na vacuum - umuyoboro wuzuye, imiyoboro ya microscale (mm 0.1-2 mm), hamwe na - ubucucike bukabije. Kubungabunga neza ni ngombwa mu kubungabunga ubusugire bw’imiterere, uburyo bwo guhererekanya ubushyuhe, no kurwanya ruswa - ibintu byingenzi byongera ubuzima bwa serivisi yo guhanahana ingufu za mikorobe (MCHEs). Hasi nubuyobozi burambuye bwo kubungabunga bukubiyemo ibikorwa byingenzi na MCHE - ijambo ryihariye:
1. Isuku isanzwe: Irinde Kwimura Ubushyuhe
Imiyoboro ya Microchannel hamwe numuyoboro utemba bikunda gufungwa numukungugu, umwanda, cyangwa ibisigazwa byamavuta ya firigo, bigabanya ubuso bwiza bwo kohereza ubushyuhe kandi bikongera umuvuduko ukabije.
Kurangiza Ubuso: Koresha igitutu gito - (Ntibisanzwe cyangwa bingana na 300 psi) umwuka wugarije cyangwa umuyonga woroshye - wohanagura kugirango ukureho imyanda irekuye mumatako. Kubitsindira kunangira (urugero, amavuta, igipimo), koresha isuku ya pH itabogamye (irinde ibisubizo bya acide / alkaline yangiza mikorobe ya aluminium) hanyuma woge n'amazi ya deioni. Kuma hejuru neza kugirango wirinde ubushuhe - bwangirika.Icyitonderwa: Irinde indege - umuvuduko wamazi - barashobora kunama cyangwa kwangiza udukoko duto duto duto, guhagarika umwuka no guhanahana ubushyuhe.
Imiyoboro yimbere yimbere. Igenzura umuvuduko utemba (Nturenze cyangwa uhwanye na 10 L / min) kugirango wirinde umuvuduko ukabije ushobora kwangiza imiyoboro yoroheje -.
2. Kurinda ruswa: Kurinda Aluminium Alloy Core
Aluminium, ibikoresho byibanze bya MCHE, irashobora kwandura ruswa (biturutse ku butumburuke, umunyu {{0} air umwuka wuzuye, cyangwa umwanda wa aside). Kurinda ibikorwa ni ngombwa:
Gufata neza: Kugenzura ibirwanya anti - byangirika (urugero, resin ya fenolike, epoxy, cyangwa fluoropolymer) buri gihembwe. Kora ahantu ucagaguye cyangwa ucagaguye hamwe nubushyuhe bwo hejuru - ubushyuhe - butwikiriye (uburebure bwa firime yumye: 20-50 mm) kugirango ushire hejuru ya aluminiyumu. Kuri chillers mu turere two ku nkombe, shyiramo ikindi gipimo cya anti - gitera umunyu buri mwaka.
Kugenzura Ubushuhe: Menya neza ko icyuma gikonjesha cya chiller kidafunze kugirango wirinde amazi ahagaze gutemba kuri mikorobe. Shyiramo dehumidifiyeri mucyumba cyibikoresho niba ubuhehere burenze 60% - Ubushyuhe bwinshi bwihutisha kwangirika kwa galvanike hagati ya aluminiyumu n’umurongo wa firigo.
Inhibitori ya ruswa. Hitamo inhibitor zitari - zifite ubumara kuri aluminium (urugero, silikate - ishingiye kuri inhibitor) kugirango wirinde kwangiza inkuta za microchannel.
3. Kumenya kumeneka: Zigama Vacuum - Ingingo zishaje
Imiyoboro ya Microchannel yishingikiriza kuri vacuum - intera isobekeranye hagati yigituba kiringaniye hamwe nu mutwe - kumeneka hano bitera igihombo cya firigo, kugabanya imikorere, no kwangirika kwingenzi.
Kwipimisha Inzira ya Helium. Kuri chillers nini, koresha icyuma gipima helium kugirango usuzume imitwe ya microchannel hamwe na fin - imiyoboro ya tube - wibande kubice bikunda guhangayikishwa nubushyuhe (urugero, hafi ya firigo / gusohoka).
Kwipimisha Kwangirika: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 kumeneka bisaba guhita bisanwa (urugero, re - gutondagura ingingo nto cyangwa gusimbuza imiyoboro yangiritse).
4. Gukurikirana ibikorwa: Irinde kurenza urugero na Stresse yubushyuhe
Imikorere idakwiye (urugero, ubushyuhe bukabije bukabije, ihindagurika ry umuvuduko w umuvuduko) bitera guhangayikishwa nubushyuhe kumiterere ya microchannel, biganisha kumunaniro uhuriweho cyangwa kuvunika.
Kugenzura Ibyingenzi: Gukomeza gukurikirana:
Ubushyuhe: Gumana Ntibiri munsi cyangwa bingana na dogere 55 (kuri sisitemu ya R134a) kugirango wirinde gushyuha cyane ya aluminium - ubushyuhe bwo hejuru bugabanya icyuho - iminyururu.
Igitutu: Monitor the refrigerant side pressure drop across the microchannel core; a sudden increase (>20% byibanze) byerekana umuyoboro utemba.
Igipimo cy'Uruzi: Komeza igipimo gihamye cya firigo / ikirere (wirinde gutungurwa gutunguranye) kugirango wirinde gutembera kwamazi, bishobora kugira ingaruka no kwangiza gufungura imiyoboro.
Irinde - Kwinjira kwizuba.
5. Imyitozo ikwiye yo kubungabunga: Irinde ibyangiritse
Imiterere ya Microchannel (utubuto duto cyane, udusimba duto) dushobora kwibasirwa ningaruka za mashini - gufata neza ni ngombwa:
Gusenya neza / Inteko. Ntuzigere ushyira ibintu biremereye kumurongo wa MCHE, kuko ibi bishobora guhindura imiyoboro yimbere.
Kugenzura hamwe. Kwizirika ku bikoresho byerekana ibicuruzwa (mubisanzwe 8-12 N · m kuri aluminiyumu).
Serivise Yumwuga: Kubisana bikomeye (urugero, gusimbuza ibyuma byangiritse byangiritse, re - imitwe ya brazing), koresha abatekinisiye bahuguwe kubungabunga MCHE. Kuringaniza bidakwiye birashobora guhagarika imiyoboro ya mikorobe cyangwa gukora ingingo zidakomeye, bigabanya ubuzima bwa serivisi ya konderesi.
Mu kwibanda ku isuku isanzwe, kurinda ruswa, gutahura ibimeneka, kugenzura imikorere, no gufata neza, urashobora kongera igihe cyumurimo wa kanseri ya microchannel muri chillers - mubisanzwe kuva mumyaka 8-10 kugeza kumyaka 12-15. Iyi myitozo ntabwo ibika gusa ibice bikomeye bya MCHE (intoki ya aluminium, vacuum - ingingo zometseho, imiyoboro ya microscale) ariko kandi ikomeza uburyo bwiza bwo guhererekanya ubushyuhe, bikagabanya igihe kirekire -.
Ibirangantego: micro - umuyoboro wa chiller condenser coil, Ubushinwa micro - umuyoboro wa chiller condenser coil inganda, abatanga ibicuruzwa, uruganda
