Defrost heater element ndi imodzi mwazinthu zofunika kwambiri mufiriji ndi mafiriji. Udindo wake waukulu ndi kuteteza mapangidwe chisanu ndi kusungunula ayezi wosanjikiza anasonkhanitsa pa evaporator koyilo. Mapangidwe a chubu chotenthetsera chotenthetsera n'chofunika kwambiri kuti chipangizocho chizigwira ntchito bwino. Makamaka, mpweya wa m'firiji kapena mufiriji ukadutsa mu evaporator kuti uzizizire, chinyontho cha mumlengalenga chikhoza kukhazikika ndikuundana pang'onopang'ono pamwamba pa evaporator. Ngati zigawo za chisanuzi sizichotsedwa panthawi yake, zimakula pang'onopang'ono ndikulepheretsa kufalikira kwa mpweya wozizira, motero zimakhudza kufanana ndi kukhazikika kwa kutentha kwa mkati mwa zipangizo.
Pofuna kuonetsetsa kuti mafiriji kapena mafiriji amatha kupereka malo osatentha nthawi zonse, opanga nthawi zambiri amaika makina oziziritsira okha pazida. Chigawo chapakati pa dongosololi ndi kutentha kwa defrost, komwe kumayamba pakapita nthawi yodziwikiratu ndikusamutsa kutentha koyenera kupita ku ma evaporator kuti asungunuke madzi oundana. Izi nthawi ndi nthawi ntchito defrosting sikuti kumathandiza kuti mpweya wosalala kumayenda mkati mwa zipangizo komanso kwambiri bwino firiji dzuwa ndi kuchepetsa kugwiritsa ntchito mphamvu.
Mfundo yowonongeka mufiriji - Kodi firiji yoziziritsidwa ndi mphepo ndi chiyani
Ubwino waukulu wa firiji yowonongeka ndi mphepo ndikuti alibe chisanu. Mosiyana ndi mafiriji okhala ndi firiji, firiji yozizidwa ndi mphepo sikhala ndi chinyontho nthawi zonse mkati, ndipo chakudya sichimamatirana. Komanso, firiji yoziziritsidwa ndi mphepo imakhala ndi mpweya wozizira wosalekeza, womwe umasefedwa ndi dongosolo la deodorization, ndipo fungo lamkati lidzasungidwa mwatsopano kwa nthawi yaitali, popanda "fungo la firiji" losasangalatsa. Firiji yoziziritsidwa ndi mphepo ilibe chisanu; M'malo mwake, chisanu chimakhazikika pa evaporator. Popeza kuti ili m’kati mwa furiji, sitingathe kuiwona mwachindunji chitseko cha firiji chotsegula, chotero mophiphiritsira imatchedwa kuti yopanda chisanu. Kuphatikiza apo, chifukwa firiji yozizidwa ndi mphepo imatha kusungunuka yokha.
Mfundo yochepetsera firiji yoziziritsidwa ndi mphepo - Mfundo yogwira ntchito yochepetsera mufiriji yoziziritsidwa ndi mphepo.
Njira yochepetsera madzi ikamalizidwa m'njira yapitayi, chowerengera choziziritsa chimalumikizana ndi mzere wa imvi ndipo mzere wa lalanje umalumikizidwa, ndipo chowerengera, kompresa, ndi fani zonse zimayamba kuthamanga nthawi imodzi. The defrosting timer chikugwirizana mu mndandanda ndi chotenthetsera defrost, koma chifukwa chachikulu kukana mkati kwa defrost timer ndi ang'onoang'ono kukana mkati mwa chotenthetsera defrost, ambiri voteji ntchito defrost timer, ndi defrost chotenthetsera amapanga kutentha pang'ono kwambiri. Pamene chowerengera cha defrost ndi kompresa zikuyenda nthawi imodzi kwa maola 8, zolumikizana ndi mzere wa imvi wa defrost ndi mzere walalanje zimalumikizidwa. Chotenthetsera cha defrost chimayendetsedwa mwachindunji ndi fusesi ndi chosinthira cha defrost, ndipo mota ya defrost imafupikitsidwa ndi kusintha kwa kutentha kwa defrost. The defrost timer imasiya kugwira ntchito.
Pamene chisanu chasungunuka kwathunthu, kutentha kwa pamwamba pa evaporator kumakwera kufika pa 10-16 ° C, makina osinthira kutentha kwa defrost amachotsedwa ku dera la defrost, ndipo nthawi yomweyo, timer ya defrost imayamba kuthamanga. Pakatha pafupifupi mphindi 5, kulumikizana kwa mzere wa imvi ndi mzere wa lalanje kumalumikizidwanso, ndikumaliza njira imodzi yokhayokha. Compressor ndi fan zimayambanso kuthamanga kuti zisungidwe mufiriji. Kenaka, pamene kutentha kwa evaporator kumatsikira pa kukonzanso kutentha kwa kusintha kwa kutentha kwa kutentha kwa defrost, kusintha kwa kutentha kumatsekedwa kuti kulumikiza chotenthetsera cha defrost, kukonzekera defrosting yotsatira.
Komabe, ngati chotenthetsera cha defrost sichikuyenda bwino, monga chifukwa cha ukalamba, kupsa mtima, kapena kusalumikizana bwino kwa dera, zitha kulepheretsa kuzungulira kwa defrost kugwira ntchito bwino. Chotsatira chake, chisanu pa evaporator chikhoza kuwunjikana mofulumira, kutsekereza njira yopita kwa mpweya ndikupangitsa kuti zikhale zovuta kuti zipangizo zisunge kutentha kwapadera. Izi sizimangokhudza kasungidwe ka chakudya komanso zimawonjezera kupsinjika pazinthu zazikulu monga kompresa, ndipo zimatha kuwononga zida. Chifukwa chake, mukaona kuchepa kwa kuzizira kwa firiji kapena mufiriji, kuchuluka kwa chisanu mkati mwawo, kapena kuchuluka kwamphamvu kwamagetsi, muyenera kuyang'ana nthawi yomweyo momwe dongosolo la defrost lilili.
Ngati mukukayikira kuti chinthu chotenthetsera cha defrost ndi cholakwika, tikulimbikitsidwa kuti mutenge njira zotsatirazi posachedwa: Choyamba, chotsani mphamvu yamagetsi kuti mutsimikizire chitetezo; chachiwiri, gwiritsani ntchito ma multimeter kuti muyese kukana kwa chinthu chotenthetsera kuti muwone ngati chili mkati mwazoyenera kugwira ntchito; potsiriza, ngati zatsimikiziridwa kuti chigawocho chawonongeka, muyenera kugula gawo latsopano lomwe likufanana ndi chitsanzo choyambirira cha m'malo. Posunga ndikusintha zida zolakwika munthawi yake, mutha kuwonjezera moyo wautumiki wa firiji kapena mufiriji ndikuwonetsetsa kuti nthawi zonse imagwira ntchito bwino.
