Uwitekaicyuma gikonjeshani ibikoresho byumye byumuyaga bifashisha bifashisha amahame yumubiri kugirango uhagarike ubushuhe bwumuyaga wugarijwe munsi yikime, ukayihuza mumazi yamazi ava mumyuka yugarijwe akayirekura. Kugarukira ku mazi akonjesha, mubyukuri ubushyuhe bwacyo bwikime burashobora kuba hafi dogere 0. Mu myitozo, ubushyuhe bwikime cyumushi mwiza wumukonje urashobora kugera kuri dogere 10.
Ukurikije itandukaniro riri hagati yubushyuhe bwaibyuma bikonjesha, kuri ubu hariho ubwoko bubiri bwumuyaga hamwe noguhindura ubushyuhe bwa tube-fin hamwe nubushyuhe bwo mu bwoko bwa plaque (byitwa guhanahana amasahani) kumasoko. Bitewe nubuhanga bukuze, imiterere yoroheje, ikora neza yubushyuhe, kandi nta mwanda wongeyeho, icyuma gishyushya ikirere cyabaye isoko nyamukuru yisoko ryumuyaga. Nyamara, hari ibibi byinshi mugushushanya no gukoresha imashini ishaje ya tube-fin. Imikorere nyamukuru mubice bikurikira:
1. Ingano nini:
Guhindura ubushyuhe bwa tube-fin muri rusange bifite imiterere ya silindrike itambitse. Kugirango uhuze nuburyo bwo guhinduranya ubushyuhe, igishushanyo cyose cyimashini ikonjesha kandi yumisha irashobora gukurikiza gusa uburyo bwo guhinduranya ubushyuhe. Kubwibyo, imashini yose ni nini, ariko umwanya wimbere urimo ubusa. , Cyane cyane kubikoresho biciriritse kandi binini, 2/3 byumwanya uri imbere ya mashini yose irarenze, bityo bigatera imyanda idakenewe.
2. Imiterere imwe:
Guhindura ubushyuhe bwa tube-fin muri rusange bifata igishushanyo kimwe kuri kimwe, ni ukuvuga, ubushobozi bwo gutunganya ibyuma byumuyaga bihuye nubushobozi bwo gutunganya ubushyuhe bujyanye nubushyuhe, bikavamo imbogamizi mubikorwa byumusaruro kandi ntibishobora gukoreshwa muburyo bworoshye. Uburyo bwo gukoresha ubushyuhe bumwe bwo gukora ibyuma byumuyaga bifite ubushobozi butandukanye bwo gutunganya, byanze bikunze bizamura ubwiyongere bwibikoresho fatizo.
3. Impuzandengo yo guhanahana ubushyuhe
Ubushyuhe bwo guhererekanya ubushyuhe bwa tube-fin ihinduranya ubushyuhe muri rusange ni 85%, bityo rero birakenewe ko tugera ku ngaruka nziza yo guhererekanya ubushyuhe. Igishushanyo cya sisitemu yose yo gukonjesha igomba kwiyongera hejuru ya 15% hashingiwe ku kubara ibisabwa ubushobozi bwa firigo, bityo byongera ikiguzi cya sisitemu no gukoresha ingufu.
4. Ibyuka bihumeka mumashanyarazi
Imiterere ya kare ya finike hamwe nigikonoshwa cyumuzunguruko wa tube-fin ihinduranya ubushyuhe isiga umwanya wo kudahana ubushyuhe muri buri muyoboro, bigatera umwuka mwinshi. Urujijo rwumuyaga rutuma umwuka uhumeka uhunga nta guhana ubushyuhe. Ibi bigabanya ikime cya gaze yibicuruzwa, kandi kongera ubushobozi bwo gukonjesha ntibikemura burundu ikibazo. Kubwibyo, ikime cyumuvuduko wumuyoboro wa fin-fin ukonjesha muri rusange uri hejuru ya 10 ° C, idashobora kugera kuri 2 ° C.
5. Kurwanya ruswa nabi
Guhinduranya ubushyuhe bwa Tube-fin mubusanzwe bikozwe mumiyoboro yumuringa na aluminiyumu, kandi intego igenewe ni gaze isanzwe isunikwa na gaze idashobora kwangirika. Iyo bikoreshejwe mubihe bimwe bidasanzwe, nk'ibyuma bikonjesha byo mu nyanja, imashini idasanzwe yo gukonjesha no kumisha imashini, nibindi, bikunda kwangirika, bigabanya cyane ubuzima bwa serivisi, cyangwa ntibishobora no gukoreshwa na gato.
Urebye ibiranga twavuze haruguru twahinduye tube-fin ubushyuhe, guhinduranya ubushyuhe bwa plaque birashobora kuzuza ibyo bitagenda neza. Ibisobanuro byihariye ni ibi bikurikira:
1. Imiterere yoroheje nubunini buto
Isahani ihinduranya isahani ifite imiterere ya kare kandi ifite umwanya muto. Irashobora guhuzwa neza nibikoresho bya firigo mubikoresho bidafite imyanda ikabije.
2. Icyitegererezo kiroroshye kandi kirahinduka
Guhindura ubushyuhe bwa plaque birashobora guteranyirizwa muburyo bwa modular, ni ukuvuga, birashobora guhuzwa mubushobozi bukenewe bwo gutunganya muburyo bwa 1 + 1 = 2, bigatuma igishushanyo cyimashini yose ihinduka kandi igahinduka, kandi irashobora kugenzura neza kubara ibikoresho fatizo.
3. Gukoresha ubushyuhe bwinshi
Umuyoboro utemba wa plaque yubushyuhe ni ntoya, isahani ya plaque ni imiterere, kandi impinduka zambukiranya ibice ziragoye. Isahani ntoya irashobora kubona ahantu hanini ho guhanahana ubushyuhe, kandi icyerekezo cyogutemba nigipimo cyamazi cyamazi gihora gihinduka, ibyo bikaba byongera umuvuduko wamazi. Guhungabana, bityo irashobora kugera kumuvurungano ku gipimo gito cyane. Muri shell-na-tube ihinduranya ubushyuhe, ayo mazi yombi atemba kuruhande rwigitereko no kuruhande rwigikonoshwa. Mubisanzwe, imigezi ni cross-flow, na logarithmic impuzandengo yubushyuhe bwo gutandukanya ikosora ni nto. , Na plaque yubushyuhe bwa plaque ahanini ni co-current cyangwa contre-current flow, kandi coeffisente yo gukosora isanzwe igera kuri 0.95. Byongeye kandi, urujya n'uruza rw'amazi akonje kandi ashyushye mu guhinduranya ubushyuhe bw'isahani birasa n'ubuso bwo guhanahana ubushyuhe nta byerekezo byuzuzanya, bigatuma icyuma gihinduranya ubushyuhe Icyapa Itandukaniro ry'ubushyuhe ku iherezo ry'umuhinduzi w'ubushyuhe ni rito, rishobora kuba munsi ya 1 ° C. Kubwibyo, ikime cyumuvuduko wumushi wa firigo ukoresheje icyuma gipima ubushyuhe gishobora kuba munsi ya 2 ° C.
4. Nta mpande ipfuye yo guhana ubushyuhe, ahanini igera ku guhana ubushyuhe 100%
Bitewe nuburyo budasanzwe, guhinduranya ubushyuhe bwa plaque bituma uburyo bwo guhanahana ubushyuhe buterana neza hejuru yisahani nta guhana ubushyuhe bwapfuye, nta mwobo uva, kandi nta mwuka uva. Kubwibyo, umwuka uhumanye urashobora kugera ku guhana ubushyuhe 100%. Menya neza ko ikime cyibicuruzwa byarangiye.
5. Kurwanya ruswa
Guhinduranya ubushyuhe bwa plaque bikozwe muri aluminiyumu cyangwa ibyuma bitagira umwanda, bifite imbaraga zo kurwanya ruswa kandi birashobora no kwirinda kwanduza ikirere cya kabiri. Kubwibyo, irashobora guhuzwa nibihe bidasanzwe, harimo amato yo mu nyanja, hamwe na gaze yangirika Inganda zikora imiti, hamwe n’ibiribwa bikomeye n’inganda zikora imiti.
Uhujije ibiranga haruguru, guhinduranya ubushyuhe bwa plaque bifite ibyiza bitavogerwa byumuyoboro hamwe nubushyuhe bwa fin. Ugereranije na tube na finans yubushyuhe, isahani yubushyuhe irashobora kuzigama 30% mubushobozi bumwe bwo gutunganya. Kubwibyo, iboneza rya sisitemu yo gukonjesha imashini yose irashobora kugabanukaho 30%, kandi ingufu zishobora no kugabanuka kurenga 30%. Ingano yimashini yose irashobora kandi kugabanuka kurenza 30%.
Iheruka guhinduranya isahani ihinduranya firigo ikonjesha
