Kuwunika kwa zolakwika 10 zodziwika bwino pakukonza mafiriji ndi kukonza zolakwika
1. Kutentha kwa mpweya wa firiji kumakhala kochepa kwambiri
Kuthamanga kwa mpweya kumakhala kochepa kwambiri, ngakhale kuti chodabwitsachi chikuwonekera kumbali yothamanga kwambiri, koma chifukwa chake nthawi zambiri chimakhala chochepa.Zifukwa zake ndi:
1. Phokoso la valve yowonjezera latsekedwa, madzi amadzimadzi amachepetsedwa kapena ngakhale kuyimitsidwa, ndipo kuthamanga ndi kutulutsa mpweya kumachepetsedwa panthawiyi.
2. Valve yowonjezera imatsekedwa ndi ayezi kapena zonyansa, ndipo fyuluta imatsekedwa, zomwe mosakayikira zidzachepetsa kuyamwa ndi kutulutsa mpweya;mtengo wa refrigerant ndi wosakwanira;
2. Refrigeration dongosolo amapeza madzi backflow
1. Kwa makina ang'onoang'ono a firiji pogwiritsa ntchito machubu a capillary, kuwonjezera kwamadzimadzi kumapangitsa kuti madzi abwerere.Pamene evaporator yazizira kwambiri kapena chowotcha chikalephera, kutentha kumakhala kosauka, ndipo madzi omwe alibe nthunzi amachititsa kuti madzi abwerere.Kusinthasintha kwa kutentha kwafupipafupi kumapangitsanso kuti valavu yowonjezera isayambe kuyankha ndikupangitsa madzi kubwereranso.
2. Kwa machitidwe a firiji pogwiritsa ntchito ma valve owonjezera, kubwerera kwamadzimadzi kumagwirizana kwambiri ndi kusankha ndi kugwiritsa ntchito molakwika ma valve owonjezera.Kusankhidwa kwakukulu kwa valve yowonjezera, kutentha kwazing'ono kwambiri, kuyika kolakwika kwa phukusi la kutentha kwa kutentha kapena kuwonongeka kwa kukulunga kwa kutentha kwa kutentha, kapena kulephera kwa valve yowonjezera kungayambitse madzi kubwerera.
Kwa kachitidwe ka firiji komwe kubweza kwamadzi kumakhala kovuta kupeŵa, kuyika chiwongolero cha gasi-madzimadzi olekanitsa kumatha kupewa kapena kuchepetsa kuvulaza kwamadzimadzi.
3. Kutentha kwa kutentha kwa firiji ndikokwera kwambiri
1. Kutentha koyamwa ndikwambiri chifukwa chazifukwa zina, monga kutsekeka kosakwanira kwa payipi ya gasi yobwerera kapena mapaipi atali kwambiri, zomwe zingayambitse kutentha kwambiri.Nthawi zonse, mutu wa silinda wa kompresa uyenera kukhala wozizira ndi theka wotentha.
2. Chiwongoladzanja cha refrigerant mu dongosolo sichikwanira, kapena kutsegula kwa valve yowonjezera kumakhala kochepa kwambiri, zomwe zimapangitsa kuti mafiriji asamayende bwino m'dongosolo, firiji yocheperapo imalowa mu evaporator, kutentha kwakukulu, ndi kutentha kwakukulu.
3. Chophimba cha fyuluta cha doko la valve yowonjezera chatsekedwa, madzi amadzimadzi mu evaporator sakwanira, kuchuluka kwa refrigerant kumachepetsedwa, ndipo gawo la evaporator limakhala ndi nthunzi yotentha kwambiri, kotero kutentha kwakuya kumakwera.
4. Madzi
1, ayenera kupewa kutentha kuyamwa ndi okwera kwambiri kapena otsika kwambiri.Kutentha kochulukirapo, ndiko kuti, kutentha kwambiri, kumapangitsa kuti kutentha kwa kompresa kukwera.Ngati kuyamwa kutentha ndi otsika kwambiri, zikutanthauza kuti refrigerant si kwathunthu chamunthuyo mu evaporator, amene osati amachepetsa kutentha kuwombola dzuwa la evaporator, ndi kuyamwa kwa nthunzi chonyowa adzapanganso madzi mantha mu kompresa.Nthawi zambiri, kutentha kwa kuyamwa kuyenera kukhala 5-10 ° C kuposa kutentha komwe kumatuluka.
2. Pofuna kuonetsetsa kuti compressor ikugwira ntchito bwino ndikuletsa kuchitika kwa nyundo yamadzimadzi, kutentha kwa mpweya kumafunika kukhala kwakukulu kuposa kutentha kwa evaporation, ndiko kuti, kuyenera kukhala ndi kutentha kwakukulu.
5. Yambani dongosolo la firiji ndi madzi
1. Chodabwitsa kuti mafuta odzola mu kompresa thovu mwamphamvu amatchedwa kuyamba ndi madzi.Kutulutsa thovu poyambira ndi madzi kumatha kuwonedwa bwino pagalasi lowonera mafuta.Chifukwa chachikulu ndi chakuti kuchuluka kwa refrigerant kusungunuka mu mafuta opaka mafuta ndikumira pansi pa mafuta odzola mwadzidzidzi kumapweteka pamene kupanikizika kumachepa mwadzidzidzi, ndipo kumayambitsa kuphulika kwa thovu la mafuta odzola, omwe ndi osavuta kuyambitsa nyundo yamadzimadzi.
2. Kuyika kwa crankcase heater (chowotcha chamagetsi) mu kompresa kungalepheretse kusuntha kwa refrigerant.Zimitsani kwakanthawi kochepa kuti chotenthetsera cha crankcase chikhale cholimba.Pambuyo pozimitsa nthawi yayitali, tenthetsani mafuta opaka kwa maola angapo kapena khumi musanayambe makinawo.Kuyika cholekanitsa chamadzi a gasi papaipi yobwerera kungapangitse kukana kwa kusamuka kwa refrigerant ndikuchepetsa kuchuluka kwa kusamuka.
6. Mafuta kubwerera mu firiji dongosolo
1. Kupanda mafuta kungayambitse kusowa kwamafuta.Choyambitsa cha kuchepa kwa mafuta si kuchuluka kwake komanso momwe compressor imathamangira mwachangu, koma kubweza kwamafuta kosauka kwa dongosolo.Kuyika cholekanitsa mafuta kumatha kubweza mafuta mwachangu ndikutalikitsa nthawi yogwira ntchito ya kompresa popanda mafuta kubwerera.
2. Pamene kompresa ndi apamwamba kuposa evaporator, mafuta kubwerera anapinda pa ofukula kubwerera chitoliro ndi zofunika.Msampha wobwereranso wamafuta uyenera kukhala wophatikizika momwe ungathere kuti uchepetse kusungirako mafuta.Kusiyana pakati pa zopindika zobwerera mafuta kuyenera kukhala koyenera.Pamene kuchuluka kwa mafuta obwerera kumakhala kwakukulu, mafuta ena odzola ayenera kuwonjezeredwa.
3. Kuyambika pafupipafupi kwa kompresa sikuthandiza kuti mafuta abwerere.Chifukwa nthawi yogwira ntchito mosalekeza ndi yochepa kwambiri, kompresa imayima, ndipo palibe nthawi yopangira mpweya wothamanga kwambiri mu chitoliro chobwerera, kotero kuti mafuta odzola amatha kukhala mu payipi.Ngati mafuta obwerera ali ochepa kuposa mafuta othamanga, compressor idzakhala yochepa mafuta.Kufupikitsa kwa nthawi yothamanga, kutalika kwa mapaipi, kuwonjezereka kwa makina, ndipamenenso vuto lobwezeretsa mafuta limawonekera kwambiri.
7. Evaporation kutentha kwa firiji dongosolo
Kuzizira kozizira kumakhudza kwambiri kuzizira bwino.Pakuchepa kwa digirii imodzi iliyonse, mphamvuyo imayenera kuonjezedwa ndi 4% kuti ipeze kuzizira komweko.Choncho, ngati zinthu zilola, n’kopindulitsa kuonjezera kutentha kwa nthunzi moyenerera kuti choziziritsira mpweya chizigwira ntchito bwino m’firiji.
Kutentha kwa mpweya wa mpweya wa m'nyumba nthawi zambiri kumakhala pansi pa madigiri 5-10 kuposa kutentha kwa mpweya wa mpweya wa mpweya.Pa ntchito yachibadwa, kutentha kwa mpweya ndi madigiri 5-12, ndi kutentha kwa mpweya ndi madigiri 10-20.
Kutsitsa mwakhungu kutentha kwa nthunzi kumatha kuziziritsa kusiyana kwa kutentha, koma kuziziritsa kwa kompresa kumachepa, kotero kuti kuzizira sikuyenera kukhala kofulumira.Kuonjezera apo, kutsika kwa kutentha kwa mpweya, kutsika kozizira kozizira, koma katundu ukuwonjezeka, nthawi yogwira ntchito imatalika, ndipo kugwiritsa ntchito mphamvu kumawonjezeka.
Eyiti, kutentha kwa mpweya wa firiji ndikokwera kwambiri
Zifukwa zazikulu za kutentha kwapamwamba kwambiri ndi izi: kutentha kwakukulu kwa mpweya wobwerera, kutentha kwakukulu kwa galimoto, kuthamanga kwapamwamba kwambiri, kuthamanga kwapamwamba kwambiri, chiwerengero cha adiabatic cha refrigerant, ndi kusankha kosayenera kwa refrigerant.
Nayi, refrigeration system fluoride
1. Pamene kuchuluka kwa fluorine kumakhala kotsika kapena kupanikizika kwake kumachepa (kapena kutsekedwa pang'ono), boneti (mavuvu) a valve yowonjezera komanso ngakhale madzi olowera madzi adzakhala chisanu;pamene kuchuluka kwa fluorine kuli kochepa kwambiri kapena kwenikweni kulibe fluorine, maonekedwe a valavu yowonjezera Palibe yankho, phokoso laling'ono lokha la mpweya limamveka.
2. Yang'anani kumapeto komwe icing imayambira, kaya ndi mutu wa dispenser kapena kuchokera ku compressor kubwerera ku trachea.Ngati mutu wa dispenser ulibe fluorine, compressor imatanthauza kuti fluorine yachuluka.
10. Kutentha kwa kutentha kwa firiji kumakhala kochepa
1. Kutsegula valavu yowonjezera ndi yaikulu kwambiri.Chifukwa chinthu chozindikira kutentha chimakhala chomangidwa momasuka, malo olumikizirana ndi chitoliro cha mpweya wobwerera ndi wocheperako, kapena chinthu chozindikira kutentha sichimakutidwa ndi zinthu zotenthetsera zotenthetsera ndipo malo ake omangira ndi olakwika, ndi zina zotero, kutentha kumayesedwa ndi kutentha. chinthucho sicholondola, ndipo chiri pafupi ndi kutentha kozungulira, zomwe zimapangitsa kuti valavu yowonjezera igwire ntchito.Digiri yotsegulira imachulukitsidwa, zomwe zimapangitsa kuti pakhale madzi ambiri.
2. The refrigerant charge is too much, yomwe imatenga gawo la voliyumu ya condenser ndikuwonjezera kuthamanga kwa condenser, ndipo madzi omwe amalowa mu evaporator amawonjezeka molingana.Madzi omwe ali mu evaporator sangathe kusungunuka kwathunthu, kotero kuti mpweya woyamwa ndi kompresa uli ndi madontho amadzimadzi.Mwanjira imeneyi, kutentha kwa payipi yobwereranso kumachepa, koma kutentha kwa evaporation sikumasintha chifukwa kuthamanga sikutsika, ndipo kuchuluka kwa kutentha kwakukulu kumachepa.Palibe kusintha kwakukulu ngakhale valve yowonjezera itatsekedwa.
