Isixhobo se-defrost heater sesinye sezona zinto zibalulekileyo kwiifriji nakwiifriji. Uxanduva lwaso oluphambili kukuthintela ukwakheka kweqabaka ngokunyibilikisa umaleko womkhenkce oqokelelene kwiikhoyili ze-evaporator. Uyilo lwetyhubhu ye-defrost heater lubalulekile ekugcineni ukusebenza okuqhelekileyo kwezixhobo. Ngokukodwa, xa umoya ongaphakathi kwifriji okanye kwifriji udlula kwi-evaporator ukuze uphole, umswakama emoyeni unokuxinana kwaye kancinci kancinci uqine phezu komphezulu we-evaporator. Ukuba ezi layers zeqabaka azisuswanga ngexesha, ziya kuqina kancinci kwaye zithintele ukujikeleza kakuhle komoya obandayo, ngaloo ndlela zichaphazela ukufana kunye nokuzinza kobushushu bangaphakathi bezixhobo.
Ukuqinisekisa ukuba iifriji okanye iifriji zinokubonelela ngokuqhubekayo ngemeko-bume yobushushu obuphantsi, abavelisi badla ngokufaka inkqubo yokunyibilikisa ngokuzenzekelayo kwizixhobo. Icandelo eliphambili lale nkqubo yinxalenye yokufudumeza enyibilikisa iqhwa, eqala ngamaxesha amiselweyo kwaye idlulisele ubushushu obufanelekileyo kwiikhoyili ze-evaporator ukuze inyibilikise umkhenkce oqokelelweyo. Olu sebenzi lokunyibilikisa iqhwa rhoqo aluncedi nje kuphela ukugcina ukujikeleza komoya okugudileyo ngaphakathi kwezixhobo kodwa lukwaphucula kakhulu ukusebenza kakuhle kwefriji kwaye lunciphisa ukusetyenziswa kwamandla.
Umgaqo wokunyibilikisa iifriji – Yintoni ifriji epholiswe ngumoya
Eyona nzuzo inkulu yefriji epholiswe ngumoya kukuba ayinaqabaka. Ngokungafaniyo neefriji ezineenkqubo zokupholisa, ifriji epholiswe ngumoya ayinangaphakathi elifumileyo rhoqo, kwaye ukutya akunamatheli ndawonye. Ngaphezu koko, ifriji epholiswe ngumoya inokujikeleza okuqhubekayo komoya obandayo, ohluzwa yinkqubo yokususa ivumba, kwaye ivumba langaphakathi liya kugcinwa litsha ixesha elide, ngaphandle "kwevumba lefriji" elingathandekiyo. Ifriji epholiswe ngumoya ayinaqabaka; endaweni yoko, iqabaka liyaqina kwi-evaporator. Ekubeni ingaphakathi kwifriji, asinakuyibona ngokuthe ngqo xa ucango lwefriji luvuliwe, ngoko ke ngokomfuziselo ibizwa ngokuba yi-free-frost. Ukongeza, kuba ifriji epholiswe ngumoya inokunyibilika ngokuzenzekelayo.
Umgaqo wokunyibilikisa iqhwa kwifriji epholiswe ngumoya – Umgaqo osebenzayo wokunyibilikisa iqhwa kwifriji epholiswe ngumoya
Emva kokuba inkqubo yokunyibilikisa igqityiwe kumjikelo odlulileyo, isibali-xesha sokunyibilikisa sidibana nomgca ongwevu kwaye umgca o-orenji uqhagamshelwe, kwaye isibali-xesha, i-compressor, kunye nefeni zonke ziqala ukusebenza ngaxeshanye. Isibali-xesha sokunyibilikisa siqhagamshelwe ngokulandelelana ne-defrost heater, kodwa ngenxa yokumelana okukhulu kwangaphakathi kwe-defrost timer kunye nokumelana okuncinci kwangaphakathi kwe-defrost heater, uninzi lwe-voltage lusetyenziswa kwi-defrost timer, kwaye i-defrost heater ivelisa ubushushu obuncinci kakhulu. Xa isibali-xesha sokunyibilikisa kunye ne-compressor zisebenza ngaxeshanye iiyure ezi-8 eziqokelelweyo, oonxibelelwano bomgca ongwevu we-defrost timer kunye nomgca o-orenji baqhagamshelwe. I-defrost heater inikwa amandla ngokuthe ngqo yi-fuse kunye ne-defrost switch, kwaye i-defrost motor inqunyanyiswa yi-defrost control switch. Isibali-xesha sokunyibilikisa siyayeka ukusebenza.
Xa iqabaka linyibilike ngokupheleleyo, xa ubushushu bomphezulu we-evaporator bunyuka bufikelela kwi-10-16°C, izikhombisi zokutshintsha ubushushu ezinyibilikayo ziyasuswa kwisekethe yokunyibilikisa, kwaye kwangaxeshanye, isibali-xesha sokunyibilikisa siqala ukusebenza. Emva kwemizuzu emi-5, izikhombisi zomgca ongwevu kunye nomgca o-orenji ziqhagamshelwe kwakhona, zigqibezela inkqubo enye yokunyibilikisa ngokuzenzekelayo. I-compressor kunye nefeni ziqala ukusebenza kwakhona ukuze zifrijiwe. Emva koko, xa ubushushu be-evaporator buhla bufikelela kubushushu bokuseta kwakhona beswitshi yokulawula ubushushu obunyibilikayo, iswitshi yokulawula ubushushu iyavalwa ukuze kuqhagamshelwe i-heater yokunyibilikisa, ilungiselela ukunyibilikisa okulandelayo.
Nangona kunjalo, ukuba into yokufudumeza enyibilikayo ayisebenzi kakuhle, njengokuba ngenxa yokwaluphala, ukutsha, okanye uqhagamshelo olubi lwesekethe, inokuthintela umjikelo wokunyibilikisa ukuba usebenze kakuhle. Ngenxa yoko, iqabaka kwi-evaporator inokuqokelelana ngokukhawuleza, ivale indlela yokuhamba komoya kwaye yenze kube nzima kwizixhobo ukugcina ubushushu obumiselweyo. Le meko ayichaphazeli nje kuphela ukugcinwa kokutya kodwa ikwabeka uxinzelelo olongezelelweyo kwizinto eziphambili ezifana ne-compressor, kwaye inokukhokelela ekonakaleni kwezixhobo. Ke ngoko, xa ubona ukwehla kokusebenza kokupholisa kwefriji okanye ifriji yakho, ukuqokelelwa kweqabaka okungaqhelekanga ngaphakathi, okanye ukwanda okukhulu kokusetyenziswa kwamandla, kufuneka ujonge ngoko nangoko imeko yenkqubo yokunyibilikisa.
Ukuba ukrokrela ukuba into yokufudumeza enyibilikayo inesiphako, kuyacetyiswa ukuba uthathe la manyathelo alandelayo ngokukhawuleza: Okokuqala, khupha umbane wesixhobo ukuqinisekisa ukhuseleko; okwesibini, sebenzisa i-multimeter ukuvavanya ixabiso lokumelana nento yokufudumeza ukuze ubone ukuba ikwinqanaba lokusebenza eliqhelekileyo; ekugqibeleni, ukuba kuqinisekisiwe ukuba into yonakele, kufuneka uthenge inxalenye entsha ehambelana nomzekelo wokuqala ukuze itshintshwe. Ngokugcina nokutshintsha izinto ezinesiphako ngexesha elifanelekileyo, unokwandisa ubomi benkonzo yefriji okanye ifriji kwaye uqinisekise ukuba isoloko ikwimeko efanelekileyo yokusebenza.
