Kodi mungathetse bwanji vuto la chubu chotenthetsera madzi chosungunuka chikugwira ntchito pamene firiji yoziziritsidwa ndi mpweya ikuzizira?

Chotenthetsera chosungunuka ndi chimodzi mwa zinthu zofunika kwambiri m'mafiriji ndi m'mafiriji. Udindo wake waukulu ndikuletsa kuzizira mwa kusungunula ayezi womwe umasonkhana pa ma evaporator coils. Kapangidwe ka chubu chotenthetsera chosungunuka ndi kofunikira kwambiri kuti zipangizo zigwire ntchito bwino. Makamaka, pamene mpweya mkati mwa firiji kapena mufiriji umadutsa mu evaporator kuti uzizire, chinyezi chomwe chili mumlengalenga chikhoza kuzizira pang'onopang'ono pamwamba pa evaporator. Ngati zigawozi za chisanu sizichotsedwa pakapita nthawi, pang'onopang'ono zidzakhuthala ndikulepheretsa kuyenda bwino kwa mpweya wozizira, motero zimakhudza kufanana ndi kukhazikika kwa kutentha kwamkati kwa zipangizo.

Pofuna kuonetsetsa kuti mafiriji kapena mafiriji amatha kupereka malo otentha nthawi zonse, opanga nthawi zambiri amaika makina osungunula okha mu chipangizocho. Gawo lalikulu la makinawa ndi chinthu chotenthetsera madzi, chomwe chimayamba nthawi ndi nthawi yoikidwiratu ndikusamutsa kutentha koyenera ku ma evaporator coils kuti asungunuke ayezi wosonkhanitsidwa. Ntchito yosungunula madzi nthawi ndi nthawiyi sikuti imangothandiza kuti mpweya uziyenda bwino mkati mwa chipangizocho komanso imathandizira kwambiri kuti firiji igwire bwino ntchito komanso kuchepetsa kugwiritsa ntchito mphamvu.

Mfundo yosungunula mufiriji - Kodi firiji yoziziritsidwa ndi mphepo ndi chiyani?

Ubwino waukulu wa firiji yoziziritsidwa ndi mphepo ndi wakuti ilibe chisanu. Mosiyana ndi mafiriji okhala ndi makina oziziritsira, firiji yoziziritsidwa ndi mphepo simakhala ndi mkati monyowa nthawi zonse, ndipo chakudya sichimamatirana. Kuphatikiza apo, firiji yoziziritsidwa ndi mphepo imakhala ndi mpweya wozizira womwe umayendetsedwa mosalekeza, womwe umasefedwa ndi makina ochotsera fungo, ndipo fungo lamkati lidzasungidwa latsopano kwa nthawi yayitali, popanda "fungo losasangalatsa la firiji". Firiji yoziziritsidwa ndi mphepo siili yopanda chisanu; m'malo mwake, chisanu chimasungunuka pa evaporator. Popeza ili mkati mwa firiji, sitingathe kuiwona mwachindunji ndi chitseko cha firiji chotseguka, kotero mophiphiritsa imatchedwa kuti yopanda chisanu. Kuphatikiza apo, chifukwa firiji yoziziritsidwa ndi mphepo imatha kusungunuka yokha.

Mfundo yosungunula chisanu ya firiji yoziziritsidwa ndi mphepo - Mfundo yogwirira ntchito yosungunula chisanu mufiriji yoziziritsidwa ndi mphepo

Pambuyo poti njira yosungunula itatha munthawi yapitayi, choyezera kutentha chimalumikizana ndi mzere wa imvi ndipo mzere wa lalanje umalumikizidwa, ndipo choyezera kutentha, compressor, ndi fan zonse zimayamba kugwira ntchito nthawi imodzi. Choyezera kutentha chimalumikizidwa motsatizana ndi choyezera kutentha, koma chifukwa cha kukana kwakukulu kwamkati kwa choyezera kutentha komanso kukana kochepa kwamkati kwa choyezera kutentha, magetsi ambiri amagwiritsidwa ntchito ku choyezera kutentha, ndipo choyezera kutentha chimapanga kutentha kochepa kwambiri. Choyezera kutentha ndi compressor zikayenda nthawi imodzi kwa maola 8, kulumikizana kwa mzere wa imvi wa choyezera kutentha ndi mzere wa lalanje kumalumikizidwa. Choyezera kutentha chimayendetsedwa mwachindunji ndi fuse ndi chosinthira kutentha, ndipo mota yosungunula imachepetsedwa ndi chosinthira kutentha chosungunula. Choyezera kutentha chimasiya kugwira ntchito.

Pamene chisanu chasungunuka kwathunthu, pamene kutentha kwa pamwamba pa evaporator kukwera kufika pa 10-16°C, ma contacts a defrost control switch amachotsedwa ku dera losungunuka, ndipo nthawi yomweyo, nthawi yosungunuka imayamba kugwira ntchito. Patatha mphindi pafupifupi 5, ma contacts a mzere wa imvi ndi mzere wa lalanje amalumikizidwanso, ndikumaliza njira imodzi yokha yosungunuka yokha. Compressor ndi fan zimayambanso kugwira ntchito kuti zisungidwe. Kenako, kutentha kwa evaporator kukatsika kufika pa kutentha kobwezeretsanso kwa defrost control temperature control switch, switch yowongolera kutentha imatsekedwa kuti ilumikize defrost heater, kukonzekera defrost yotsatira.

Komabe, ngati chinthu chotenthetsera chomwe chimasungunuka chikalephera kugwira ntchito bwino, monga chifukwa cha ukalamba, kuzima, kapena kulumikizana koyipa kwa ma circuit, zitha kuletsa kuti chisanu chisagwire ntchito bwino. Zotsatira zake, chisanu pa evaporator chingadziunjikane mwachangu, kutseka njira yoyendera mpweya ndikupangitsa kuti zikhale zovuta kuti zida zisunge kutentha komwe kwakhazikitsidwa. Izi sizimangokhudza kusunga chakudya komanso zimapangitsa kuti zinthu zofunika kwambiri monga compressor zisokonezeke, ndipo zitha kubweretsa kuwonongeka kwa zida. Chifukwa chake, mukawona kuchepa kwa magwiridwe antchito ozizira mufiriji kapena firiji yanu, kuchulukana kwa chisanu kosazolowereka mkati, kapena kuwonjezeka kwakukulu kwa kugwiritsa ntchito mphamvu, muyenera kuyang'ana nthawi yomweyo momwe makina osungunuka alili.

Ngati mukukayikira kuti chinthu chotenthetsera chosungunuka chili ndi vuto, tikukulimbikitsani kuti muchite izi mwachangu momwe mungathere: Choyamba, dulani magetsi a chipangizocho kuti muwonetsetse kuti chili bwino; chachiwiri, gwiritsani ntchito multimeter kuti muyese mphamvu yolimbana ndi chinthu chotenthetsera kuti mudziwe ngati chili mkati mwa nthawi yoyenera yogwirira ntchito; pomaliza, ngati zatsimikizika kuti chinthucho chawonongeka, muyenera kugula gawo latsopano lomwe likugwirizana ndi chitsanzo choyambirira kuti mulowe m'malo. Mwa kusunga ndikusintha zigawo zolakwika panthawi yake, mutha kukulitsa nthawi yogwira ntchito ya firiji kapena firiji ndikuwonetsetsa kuti nthawi zonse imakhala bwino.
