Chifukwa cha chisanu pamwamba pa evaporator mu kusungirako ozizira, izo zimalepheretsa conduction ndi kufalitsa mphamvu kuzizira kwa refrigeration evaporator (paipi), ndipo pamapeto pake amakhudza firiji kwenikweni. Pamene makulidwe a chisanu wosanjikiza (ayezi) pamwamba pa evaporator kufika pamlingo wakutiwakuti, refrigeration dzuwa ngakhale akutsikira zosakwana 30%, chifukwa chachikulu kuwononga mphamvu ya magetsi ndi kufupikitsa moyo utumiki wa firiji dongosolo. Choncho, m`pofunika kuchita ozizira yosungirako defrost ntchito yoyenera mkombero.
Defrosting cholinga
1, kukonza magwiridwe antchito a firiji;
2. Onetsetsani kuti zinthu zoziziritsidwa m'nyumba yosungiramo zinthu zili bwino
3, sungani mphamvu;
4, onjezerani moyo wautumiki wamakina osungira ozizira.
Defrosting njira
Njira zoziziritsira zoziziritsa kuziziritsa kuzizira: kutentha kwa gasi wotentha (kutentha kwa fluorine, kutentha kwa ammonia), kuthira madzi, kukhetsa magetsi, kupukuta kwamakina (kopanga) ndi zina.
1, kutentha kwa gasi
Oyenera lalikulu, sing'anga ndi yaing'ono ozizira yosungirako chitoliro defrosting mwachindunji kutentha mkulu kutentha mpweya condensate mu evaporator popanda kuletsa otaya, ndi evaporator kutentha limatuluka, ndi chisanu wosanjikiza ndi kukhetsa ozizira olowa kupasuka kapena kenaka senda. Kutentha kwa gasi wotentha ndikokwera mtengo komanso kodalirika, koyenera kukonza ndi kasamalidwe, ndipo zovuta zake zachuma ndi zomangamanga sizili zazikulu. Komabe, palinso njira zambiri zowotchera mpweya wotentha, zomwe zimachitika nthawi zonse ndikutumiza mpweya wothamanga kwambiri komanso wotentha kwambiri womwe umatulutsidwa kuchokera ku kompresa kupita ku evaporator kuti utulutse kutentha ndi kuziziritsa, kotero kuti madzi osungunuka amalowanso evaporator wina kuti amwe. kutentha ndi kusanduka nthunzi kutentha pang'ono ndi mpweya wochepa mphamvu, ndiyeno kubwerera ku kompresa suction doko kumalizitsa kuzungulira.
2, madzi opopera defrost
Amagwiritsidwa ntchito kwambiri kuziziritsa ma chillers akulu ndi apakatikati
Nthawi ndi nthawi kupopera evaporator ndi kutentha kwa chipinda madzi kusungunula chisanu wosanjikiza. Ngakhale kuti defrosting zotsatira zake ndi zabwino kwambiri, ndizoyenera kwambiri zoziziritsira mpweya, ndipo zimakhala zovuta kugwiritsa ntchito ma koyilo a evaporation. N'zothekanso kupopera evaporator ndi yankho ndi apamwamba kuzizira kutentha, monga 5% -8% anaikira brine, kupewa chisanu mapangidwe.
3. Kuwotcha magetsi
Magetsi kutentha chitoliro defrosting makamaka ntchito sing'anga ndi yaing'ono mpweya ozizira; Kuwotcha kwa waya wamagetsi kumagwiritsidwa ntchito kwambiri m'machubu ang'onoang'ono ndi ang'onoang'ono osungira aluminiyamu
Kutentha kwamagetsi kutenthetsa, chifukwa chozizira ndi chosavuta komanso chosavuta kugwiritsa ntchito; Komabe, pankhani ya zosungirako zozizira za aluminium chubu, zovuta zomanga za aluminiyamu kuyika kwa waya wamagetsi sikochepa, ndipo kulephera kumakhala kokulirapo m'tsogolomu, kukonza ndi kasamalidwe kumakhala kovuta, chuma ndi chovuta, komanso chitetezo chimakhala chochepa.
4, makina ochita kupanga defrosting
Small ozizira posungira chitoliro defrosting kwa ozizira yosungirako chitoliro Buku defrosting ndi ndalama, kwambiri original defrosting njira. Kusungirako kwakukulu kozizira ndi kusungunula kochita kupanga sikungatheke, kukweza mutu kumakhala kovuta, kudya thupi kumathamanga kwambiri, kusungirako nthawi yosungiramo katundu kumakhala kotalika kwambiri kumawononga thanzi, kupukuta sikophweka, kungayambitse kuphulika kwa evaporator, ndi zitha kuthyola evaporator ndikupangitsa ngozi zotayikira mufiriji.
Kusankha mode (Fluorine system)
Malinga ndi evaporator yosiyana ya kusungirako kuzizira, njira yochepetsera yoyenera imasankhidwa, ndipo kugwiritsa ntchito mphamvu, kugwiritsa ntchito chitetezo, kuyika ndi kuvutika kwa ntchito kumafufuzidwanso.
1, njira yochepetsera ya fan yozizira
Pali magetsi amachubu defrosting ndi madzi defrosting angasankhe. Malo omwe ali ndi madzi osavuta kugwiritsa ntchito amatha kukonda madzi osungunula chisanu, ndipo malo omwe madzi akusowa amatha kusankha chitoliro chamagetsi chamagetsi chozizira. Madzi otenthetsera chisanu nthawi zambiri amakonzedwa muzowongolera mpweya, mufiriji.
2. Njira yowonongeka ya mzere wachitsulo
Pali kutentha kwa fluorine defrosting ndi njira zopangira defrosting.
3. Defrosting njira ya aluminiyamu chubu
Pali matenthedwe a fluoride defrosting ndi magetsi otenthetsera matenthedwe njira. Pogwiritsa ntchito kwambiri aluminiyamu chubu evaporator, defrosting a aluminiyamu chubu wakhala analandira chidwi kwambiri ndi ogwiritsa. Chifukwa cha zinthu zakuthupi, zotayidwa chubu kwenikweni si oyenera ntchito yosavuta ndi akhakula yokumba makina defrosting ngati chitsulo, kotero defrosting njira aluminum chubu ayenera kusankha magetsi waya defrosting ndi otentha fluorine defrosting njira, kuphatikiza mowa mphamvu, mphamvu Mwachangu chiŵerengero. ndi chitetezo ndi zinthu zina, aluminiyamu chubu defrosting n'koyenera kwambiri kusankha otentha fluorine defrosting njira.
Hot fluoride defrosting ntchito
Chida chosinthira ma freon flow direction chomwe chimapangidwa molingana ndi mfundo ya kutentha kwa gasi, kapena makina osinthira opangidwa ndi ma valve angapo amagetsi (mavavu am'manja) olumikizidwa, ndiye kuti, malo owongolera mafiriji, amatha kuzindikira kugwiritsa ntchito kutentha kwa fluorine mkati. ozizira yosungirako.
1, siteshoni yosinthira pamanja
Amagwiritsidwa ntchito kwambiri m'mafiriji akuluakulu monga kugwirizana kofanana.
2, zida zosinthira za fluorine
Amagwiritsidwa ntchito kwambiri m'mafiriji ang'onoang'ono ndi apakatikati. Monga: imodzi kiyi otentha fulorini defrosting kutembenuka chipangizo.
Kudina kamodzi kotentha fluorine defrosting
Ndiwoyenera pulogalamu yodziyimira payokha ya kompresa imodzi (yosayenera kulumikizidwa kwa mayunitsi ofananira, masitepe ambiri komanso ophatikizika). Amagwiritsidwa ntchito mu ang'onoang'ono ndi apakatikati ozizira yosungirako chitoliro defrosting ndi ayezi mafakitale defrosting.
mwapadera
1, kuwongolera pamanja, kutembenuka kumodzi kokha.
2, Kutentha kuchokera mkati, chisanu wosanjikiza ndi khoma chitoliro akhoza kusungunuka ndi kugwa, mphamvu dzuwa chiŵerengero 1:2.5.
3, kusungunuka bwino, kupitirira 80% ya chisanu ndi dontho lolimba.
4, malinga ndi chojambula chomwe chimayikidwa mwachindunji pa unit condensing, safuna zipangizo zina zapadera.
5, malinga ndi kusiyana kwenikweni kwa kutentha kozungulira, nthawi zambiri zimatenga mphindi 30 mpaka 150.
