Xa usebenzisa iikhabhathi zokugcina ezibandayo zogcino olubandayo, isikhenkcezisi kunye nekhabhathi ebandayo yokubonisa iikhabhathi, njalo njalo, kuya kubakho isenzeko sokwakheka kweqabaka kumphezulu we-evaporator. Ngenxa yomaleko weqabaka, umjelo wokuhamba uya kuba mxinwa, umthamo womoya uya kuhla, kwaye ne-evaporator iya kuvalwa ngokupheleleyo, ithintele kakhulu ukuhamba komoya. Ukuba umaleko weqabaka ungqindilili kakhulu, uya kwenza ukupholisa kunye nesiphumo sokupholisa sesixhobo sesikhenkcezisi sibe mandundu, ukonyusa amandla okusebenzisa, kwaye ezinye izixhobo zesikhenkcisi ziya kusebenzisa.defrost heater ityhubhuukunyibilika ngamaxesha athile.
Ityhubhu yesifudumezi sombane yindlela yokuphelisa iqabaka ngokufudumeza umaleko weqabaka oncanyathiselwe kumphezulu wesixhobo kusetyenziswa iityhubhu zokufudumeza ezilungiselelwe ngaphakathi kwesixhobo. Olu hlobo lwetyhubhu yesifudumezi luhlobo lwetyhubhu yentsimbi emile okwesixhobo sokufudumeza sombane, ekwabizwa ngokuba ityhubhu yokufudumeza i-defrost okanye ityhubhu yesifudumezi. I-tube yokushisa yombane yombane yinto yokufudumala yombane apho ityhubhu yesinyithi isebenza njengegobolondo, i-alloy heat wire njengento yokufudumala, kunye nesiphelo sesiphelo (iingcingo) zinikezelwa. I-insulating medium ye-magnesium oxide powder izaliswe ngokuxineneyo kwityhubhu yesinyithi ukulungisa into yokufudumeza.
Ngenxa yeempawu zezixhobo zokugcina ezibandayo, ezifana nokufuma okuphezulu kunye nobushushu obuphantsi ngaphakathi, ukubanda rhoqo kunye nokothuka okushushu,ukuphelisa iityhubhu zokufudumezangokubanzi zisekwe kwizinto zokufudumeza zombane ezimilise okwetyhubhu, zisebenzisa i-magnesium oxide ekumgangatho ophezulu eguquliweyo njengesizaliso kunye nentsimbi engatyiwayo njengeqokobhe. Emva kokunciphisa, isiphelo sokuxhamla sitywinwe ngesikhunta esikhethekileyo serubha esicinezelweyo, ukwenzela ukuba ityhubhu yokufudumala yombane isetyenziswe ngokuqhelekileyo kwizixhobo zokugcina ezibandayo. Inokugotywa kuyo nayiphi na imilo ngokweemfuno zomsebenzisi kwaye ifakwe ngokufanelekileyo kwiimbambo zomatshini womoya obandayo okanye umphezulu we-evaporator yekhabhinethi ebandayo okanye ezantsi kwi-drain tray, njl. Ulwakhiwo olusisiseko lweisifudumezi-sisibethoimi ngolu hlobo lulandelayo:
a) Intonga yokukhokela (umgca) : idibaniswe nomzimba wokufudumeza, kumacandelo kunye nokunikezelwa kwamandla, amacandelo kunye namacandelo adibaniswe kunye neendawo zokuqhuba isinyithi.
b) Umbhobho we-Shell: ngokubanzi i-304 yensimbi engenasici, ukuxhathisa okulungileyo kokuhlwa.
c) Ucingo lokufudumeza lwangaphakathi: i-nickel chromium alloy resistance wire, okanye i-iron chromium aluminiyam wire material.
d) I-port yombhobho wokushisa wombane ivalwe ngerubha ye-silicone.
Ukudibanisa umbhobho wokufudumeza, indlela yokudibanisa yeumbhobho wokufudumeza wombane wokuphelisa iqhwaibonisa ukuba uY ludibaniso olumise okwenkwenkwezi, uY kufuneka aqhagamshelwe kumgca ophakathi, kwaye ezo zingaboniswanga ziqhagamshelo ezinxantathu. Ngokomzekelo, i-tube ye-heater defrost ye-chiller ngokubanzi i-220V, kwaye enye isiphelo setyhubhu ye-heater ye-defrost ixhunyiwe kumgca womlilo, kwaye esinye isiphelo sidibaniswe kumgca ongathathi hlangothi. Ukongeza, amandla egalelo aphawulwe kwizindlu zombhobho wokufudumeza ngokuqhelekileyo amandla alinganisiweyo wetyhubhu yokufudumeza.
Indlela yokucima umbane ilula kwaye kulula ukuyisebenzisa, kodwa amandla ombaneukufudumeza ityhubhu yokufudumezabukhulu ngokubanzi, kwaye ukuba umgangatho wombhobho wokufudumeza awulungile okanye usetyenziswe ixesha elide, kulula ukutshisa okanye ubangele umlilo, ngoko ke indlela yokucima i-electric defrosting inomngcipheko omkhulu wokhuseleko kwaye kufuneka ihlolwe rhoqo. . Ityhubhu yesifudumezisi se-defrost iba lula kulo monakalo ulandelayo:
1. Ukusuka kwimbonakalo, kunokubonwa ukuba intonga ehamba phambili yonakele, i-metal surface coating yonakaliswe, i-insulator yonakaliswe okanye isitywina asiphumeleli.
I-2, iimpawu ezibonakalayo kunye neekhemikhali zombhobho wokufudumeza zitshintshile kwaye azikwazi ukuhlangabezana neemfuno zokusetyenziswa. Umzekelo, enye yezi meko zilandelayo ayinakusetyenziswa:
① Umbane wokuchasa wetyhubhu yokufudumeza ungaphantsi kwexabiso eliqhelekileyo, ixabiso langoku lokuvuza likhulu kune-5mA okanye ixabiso lokumelana ne-insulation lingaphantsi kwe-1MΩ
(2) Iqokobhe linokukhutshwa kwedangatye kunye nezinto ezinyibilikisiweyo, kwaye umphezulu wonakele kakhulu okanye awuvumelekanga ukuba ulungiswe.
③ Amandla angawona ombhobho wokufudumeza adlula amandla alinganisiweyo nge ± 10%.
④ Ubume bombhobho wokufudumeza butshintshiwe ngokunzulu, okubangele ukuba ubukhulu bomgangatho wokufakelwa kwe-insulation ngokucacileyo bungalingani, kwaye ukusebenza kwe-insulation kuncitshiswe kakhulu ngokulinganisa, okungahambelani nemigangatho efanelekileyo.
