Yadda Ake Gane Idan An Lalace Na'urar Kwamfuta Ko Evaporator?

 

 

Condensers da evaporators sune ainihin abubuwan musayar zafi na tsarin firiji, kuma matsayinsu na aiki yana tasiri kai tsaye ingancin firiji da kwanciyar hankali tsarin. Ƙayyade idan sun lalace yana buƙatar haɗa duban gani, saka idanu na aiki, kimanta aiki, da hanyoyin gwaji na taimako. A ƙasa akwai takamaiman hanyoyin yanke hukunci:

1. Duban gani

1.1 Bayanin Kayayyakin Kayayyakin Condenseraiki

 

Lalacewar jiki: Bincika idan bututun jan ƙarfe/bakin ƙarfe na na'ura mai ɗaukar nauyi sun lanƙwasa, sun lalace, ko sun karye. Don iska{1}}masu sanyaya, manyan sikelin da suka ruguje ko karaya za su rage kwararar iska kuma su rage saurin musanyar zafi. Don masu sanyaya ruwa{4}, duba harsashi don tsagewa ko ɗigon walda; Tabon ruwa, tsatsa, ko alamun mai mai sanyi suna nuna babban yuwuwar yabo.

Tari mai lalacewa: Ƙarar ƙura, mai, ko ma'auni (a cikin ruwa{0}) raka'a masu sanyaya) akan farfajiyar na'urar tana aiki azaman abin rufewa, yana haifar da ƙarancin zafi. A karkashin yanayi na al'ada, farfajiyar ya kamata ya kasance mai tsabta; ɓata sama da 0.5mm kauri (ko da ba tare da lalacewa ba) na iya haifar da kurakuran aiki - bambance tsakanin "lalacewa" da "本体"

Lalata: A cikin gaɓar teku ko maɗaukakin ɗanshi -, bututun na'urar na'ura suna da saurin lalacewa. Ganuwar bututun bakin ciki ko ramuka/ratsawa za su haifar da ɗigon ɗigo kai tsaye, wanda zai haifar da mummunar lalacewa.

1.2 Duban Kayayyakin Kaya na Evaporator

 

sanyi/kankara mara al'ada: A al'ada evaporator ya kamata da uniform bakin ciki sanyi. Kankara mai kauri na gida ko sanyi mara ma'ana (misali, sanyi mai nauyi a mashigar shiga, babu sanyi a wurin fita) na iya nuna toshewar bututu, rashin isassun firji, ko ɗigon ciki. Cikakken rashin sanyi yana buƙatar duba ɗigogi ko faɗuwar bututu.

Alamun zube: Alamun mai a saman da ake fitar da mai (firiji yana gaurayawa da man firji da yoyo da shi), musamman ma a gidajen bututu da walda, alamu ne na yabo. Don ginannun{1}a cikin magudanar ruwa, duba idan rufin yana da ɗanɗano; gyaggyarawa ko tsagewar ruwa a cikin rufi na iya rakiyar huɗawar evaporator.

Lalacewar jiki: Bututun evaporator na sirara ne - hakora, tsagewa daga tasiri, ko fashewar bututun musayar zafi na ciki za su kawar da damar musayar zafi kai tsaye.

2. Kulawa da Sigar Ayyuka

2.1 Kwatanta Sigar Zazzabi

 

Condenser: A lokacin aiki na yau da kullun, mashigin iskar -Bambancin yanayin zafi don iska{1}}masu sanyayayyu shine digiri 8-12 , kuma mashigar ruwa{4}}Bambancin kanti na ruwa{5}masu sanyayayi digiri 4-6 ne. Bambancin yanayin zafi kaɗan (<5℃) may indicate insufficient heat exchange area (e.g., damaged fins), refrigerant leakage, or fan/pump failure. An excessively large temperature difference with high-pressure alarms may signal condenser blockage or internal pipe damage causing abnormal heat exchange efficiency.

Evaporator: Matsakaicin mashiga{0}}Bambancin yanayin zafi don tsarin kwandishan yakamata ya zama digiri 10-15 . Ƙananan bambanci na iya nuna ɓarna mai fitar da iska, ɗigogi na ciki, ko rashin isasshen ruwan sanyi. Yanayin yanayin ƙasa maras al'ada (<0℃) with persistent icing may stem from pipe blockage or sensor faults, which can cause evaporator freezing and cracking over time.

2.2 Gano Sigar Matsi

 

Yi amfani da ma'aunin ma'auni don auna ma'auni mai girma da ƙananan matsa lamba: Don R22 refrigerant, matsa lamba na al'ada (bangaren na'ura) shine 1.4-1.8MPa, kuma ƙananan matsa lamba (gefen evaporator) shine 0.4-0.6MPa.

Ƙananan matsa lamba da ƙananan matsa lamba: Babban yuwuwar ɗigowar ciki (giciye mai sanyi - gudana) a cikin na'ura ko mai fitar da iska.

Babban matsin lamba da ƙananan matsa lamba: Yana iya nuna toshewar na'ura ko lalata bututun evaporator yana hana wurare dabam dabam na firiji.

Low high da low matsa lamba: Bincika don yayyafa refrigerant (evaporator/condenser perforation).

3. Ƙimar Ayyuka

3.1 Rage ƙarfin sanyaya/ dumama

 

Idan zafin jiki na cikin gida/ajiya ya kasa kai ga ƙimar da aka saita (bayan yanke hukuncin fitar da kwampreso ko kurakuran abubuwan ɓarna), yi la'akari da lalacewa ko ɓarna: Lalacewar evaporator yana rage ɗaukar zafi; Lalacewar na'urar na'urar tana haifar da mummunan zubar da zafi, yana haifar da ƙaƙƙarfan kariyar matsa lamba da katse zagayowar firiji.Misali: Ruwan kwandishan na iska yana haifar da matsanancin zafin iska na naúrar cikin gida, tare da na'urar na'ura ta waje tana gudana amma babu sakamako mai sanyaya. Mummunan lalacewar na'urar daskarewa yana haifar da matsanancin zafi a cikin babban bututun matsa lamba (har ma tare da aikin fanfo na waje na yau da kullun) da kuma rufe tsarin akai-akai.

3.2 Hayaniyar Hani da Jijjiga

 

Gwagwarmaya ta ƙarfe daga fankar na'urar na iya nuna gurɓatattun filaye da ke goge ruwan fanfo kosako-sako da na'ura mai kwakwalwa bututu suna karotare da harsashi.

Sautin "hissing" daga mai fitar da ruwa na iya sigina lalacewar bututun ciki (jiyan ruwa) ko fashewar bututu a lokacin bushewar sanyi bayan icing. Dogon girgizar da ba ta dace ba tana ƙara fashewar walda, ƙara lalacewa.

4. Hanyoyin Gwaji na Agaji

4.1 Gwajin Tsantsan Iska

 

Cika tsarin tare da nitrogen (1.8-2.0MPa) kuma riƙe matsa lamba na tsawon sa'o'i 24: Matsalolin da ya wuce 0.05MPa yana nuna yaduwa. Nemo ɗigogi ta hanyar shafa ruwan sabulu zuwa ga haɗin bututu mai ƙafewa/condenser da walda (lura don kumfa). Rikon matsi na al'ada amma rashin aikin aiki mara kyau na iya nuna ɓoyayyiyar lalacewar bututun ciki.

4.2 Gano Hoton Infrared

 

Bincika farfajiyar evaporator/condenser tare da hoton infrared thermal: Abubuwan musayar zafi na yau da kullun suna da rarraba yanayin zafi iri ɗaya. Wuraren ƙananan zafin jiki / ƙananan zafin jiki suna nuna toshewar bututu, ɗigogi, ko musanyar zafi mara kyau, yana ba da damar gano ainihin lalacewa.

4.3 Binciken Samfurin Mai

 

Ciro mai mai sanyi daga tsarin: tarkacen ƙarfe (daga mai fitar da bututun ruwa) ko danshi mai yawa (daga lalacewar bututu da shigar ruwa) a cikin mai yana nuna lalacewar injina -warkewa da dubawa.

Takaitawa

 

Ƙayyade ɓarnar na'ura mai fitar da iska yana buƙatar hanya huɗu{0}}: "binciken gani - sigogi - aiki - gwaji". Ba da fifikon duban gani don kawar da kurakuran saman, sannan yi amfani da kayan aiki don gano abubuwan da ba su dace ba, kuma a ƙarshe tabbatar da nau'in lalacewa dangane da aikin aiki. A cikin kulawar yau da kullun, tsaftace wuraren musayar zafi akai-akai da saka idanu kan sigogin aiki don gano ɓoyayyiyar ɓoyayyi da wuri da hana ɓarna kuskure.
