Izifudumezi ezinyibilikisa iqhwazizinto ezibalulekileyo kwiinkqubo zokukhenkcisa, ingakumbi kwiifriji nakwiifriji, apho indima yazo kukuthintela ukuqandusela kwiikhoyili ze-evaporator. Ukuqokelelana kweengqimba zeqhwa kunokunciphisa kakhulu ukusebenza kwezi nkqubo, ekugqibeleni kuchaphazele amandla azo okuphola.
Iityhubhu yokufudumeza yokunyibilikisa iqhwa efrijiniyinxalenye ebalulekileyo yenkqubo yokufrijisa ifriji, esetyenziswa kakhulu ukunyibilikisa umaleko weqhwa oqokelelwe kwi-evaporator kumjikelo weqhwa ozenzekelayo ukuqinisekisa ukusebenza kakuhle kwefriji.
Umsebenzi we-heater yokunyibilikisa:
ukunyibilikisa: Ngexesha lokusebenza kwefriji, umphezulu we-evaporator uya kubanda, kwaye umaleko weqhwa ongqindilili kakhulu uya kuchaphazela isiphumo sefriji.ityhubhu yesifutho sokucoca umkhenkceiyanyibilikisa umaleko weqhwa ngokufudumeza, ukuze i-evaporator ibuyele kwimeko yayo yokusebenza eqhelekileyo.
Iqabaka elizenzekelayo: Iifriji zanamhlanje zihlala zixhotyiswe ngeenkqubo zeqabaka ezizenzekelayo aphoityhubhu yokufudumeza enyibilikisa umkhenkceiza kuqala ngexesha elimiselweyo okanye phantsi kwemeko ebekiweyo ize icime ngokuzenzekelayo emva kokunyibilika.
Umgaqo osebenzayo wesifudumezi sokunyibilikisa kukufudumala i-evaporator coil ngamaxesha athile ukuze kunyibilikiswe nayiphi na iqabaka eqokelelweyo. Izifudumezi zokunyibilikisa ezisetyenziswa rhoqo zahlulwe zibe ziintlobo ezimbini: uhlobo lokufudumeza ngombane kunye nohlobo lokufudumeza ngegesi eshushu.
Izifudumezi zombane ezinyibilikisa ubushushuzihlala zifakelwa kwiifriji zasekhaya nakwiifriji. Ezi zifudumezi zenziwe ngezinto ezichaseneyo ezifana nee-nickel-chromium alloys, ezinokumelana okuphezulu kwaye zinokuvelisa ubushushu xa umbane udlula kuzo. Zibekwa ngobuchule kufutshane neekhoyili ze-evaporator okanye zifakwe ngqo kwiikhoyili.
Xa ifriji isebenza kumjikelo wokukhenkceza, ii-evaporator coils zifunxa ubushushu obuvela ngaphakathi, nto leyo ebangela ukuba umswakama emoyeni ujiye kwaye uqine kwii-coils. Ekuhambeni kwexesha, oku kwenza umaleko weqhwa. Ukuthintela ukuqokelelwa kweqhwa ngokugqithisileyo, i-defrost timer okanye ibhodi yokulawula iya kuqalisa umjikelo wokukhenkceza rhoqo, ngesiqhelo rhoqo emva kweeyure ezi-6 ukuya kwezili-12, kuxhomekeke kwimodeli yefriji.
Xa umjikelo wokunyibilikisa uqalo uqalisiwe, inkqubo yolawulo iya kuyinqumla icompressor ize isebenzeisifudumezi sokucoca ulweloUmbane udlula kwi-heater, uvelisa ubushushu bokufudumeza ii-evaporator coils. Njengoko ubushushu be-coil bunyuka, iqabaka eliqokelelweyo liqala ukunyibilika lize liguquke libe ngamathontsi amanzi.
Ukuthintela umonakalo kwinkqubo nokuqinisekisa ukunyibilika kakuhle, i-thermostat enyibilikisa ijonga ubushushu be-evaporator coil. Xa ubushushu bufikelele kwinqanaba elithile, nto leyo ebonisa ukuba iqabaka linyibilike ngokupheleleyo, i-thermostat ithumela umqondiso kwinkqubo yolawulo ukuze iyeke umjikelo wokunyibilika.
Amanzi enziwe yingqele enyibilikayo ahamba ezantsi kwi-evaporator coil aye kwi-drip pan engaphantsi kwesixhobo. Apho, adla ngokuphuma ngenxa yobushushu obuveliswa yi-compressor ngexesha lomjikelo wesiqhelo wokukhenkceza.
Kwelinye icala, iinkqubo zokunyibilikisa igesi eshushu zixhaphake kakhulu kwizixhobo ezinkulu zokufriji zorhwebo. Kwezi nkqubo, endaweni yokusebenzisa izifudumezi zombane, ifriji ngokwayo isetyenziselwa ukunyibilikisa iikhoyili. Ngexesha lomjikelo wokunyibilikisa, inkqubo yokufriji itshintsha indlela esebenza ngayo.
Ivalvu ingenisa ngqo igesi yefriji enobushushu obuphezulu kunye noxinzelelo oluphezulu ekhutshwa kwicompressor iye kwikhoyili ye-evaporator. Njengoko igesi eshushu idlula kwikhoyili, idlulisela ubushushu kumaleko weqhwa, nto leyo ebangela ukuba inyibilike. Amanzi anyibilikisiweyo ayakhutshwa. Emva kokuba umjikelo wokunyibilikisa ubushushu uphelile, ivalvu ibuyisela ifriji kwisekethe yayo yokupholisa eqhelekileyo.
Nokuba yinkqubo yokunyibilikisa ubushushu ngombane okanye inkqubo yokunyibilikisa igesi eshushu, injongo yabo kukususa umaleko weqhwa kwikhoyili ye-evaporator, kodwa basebenzisa iindlela ezahlukeneyo zokunyibilikisa ubushushu.
Ukugcinwa rhoqo kunye nokusebenza okuqhelekileyo kweiityhubhu ze-heater ezinyibilikisa umkhenkcezibalulekile ekusebenzeni kakuhle kwenkqubo yokukhenkcisa. Ukungasebenzi kakuhle kwesifudumezi kunokukhokelela ekuqokeleleni kakhulu kweqhwa, ukuncipha kokusebenza kakuhle kwefriji, kunye nomonakalo onokubakho kwizixhobo.
Izifudumezi zokunyibilikisa zidlala indima ebalulekileyo ekugcineni ukusebenza kakuhle kwenkqubo yokukhenkceza ngokuthintela iqhwa ukuba lingakheki kwiikhoyili ze-evaporator. Nokuba zisetyenziswa kukufudumala okumelanayo okanye kukufudumala ngegesi eshushu, ezi zifudumezi ziqinisekisa ukuba iikhoyili azikhenkcezi, nto leyo evumela inkqubo ukuba isebenze ngokufanelekileyo kwaye igcine ubushushu obufunekayo ngaphakathi kwisixhobo.
