Yintoni i-Defrost heater?

Isifudumezi-sifudumezi yinxalenye yecandelo lesikhenkcisi sefriji. Umsebenzi wayo ophambili kukunyibilikisa iqabaka eqokelelana kwiikhoyili ze-evaporator, iqinisekisa ukusebenza kakuhle kwenkqubo yokupholisa. Xa iqabaka ikhula kwezi khoyili, ithintela ukukwazi kwefriji ukuphola ngokufanelekileyo, nto leyo ekhokelela ekusetyenzisweni okuphezulu kwamandla kunye nokonakaliswa kokutya okunokwenzeka.

Isifudumezi se-defrost sihlala sivula ngamaxesha athile ukwenza umsebenzi waso omiselweyo, ukuvumela ifriji ukugcina amaqondo obushushu afanelekileyo. Ngokuqonda indima yesifudumezisi sokunyibilikisa, uya kukulungela ngcono ukusombulula nayiphi na imiba enokuthi ivele, ngokwenjenjalo wandisa ubomi besixhobo sakho.

Isebenza Njani Iheater?
Indlela yokusebenza kwesifudumezi-siqhumiso inika umdla kakhulu. Ngokuqhelekileyo, ilawulwa yi-timer defrost yefriji kunye ne-thermistor. Nanku ujongo olunzulu kwinkqubo:

Umjikelo weDefrost
Umjikelo we-defrost uqaliswa ngamaxesha athile, ngokuqhelekileyo rhoqo kwii-6 kwiiyure ze-12, kuxhomekeke kwimodeli yefriji kunye neemeko zokusingqongileyo ezizungezile. Umjikelo usebenza ngolu hlobo lulandelayo:

Ukusetyenziswa Kwesibali-xesha Sokunyibilikisa: Isibali-xesha sokunyibilikisa sixela isifudumezi-sinyisi ukuba sivuleke.
IsiZukulwana soBubushushu: Isifudumezi sivelisa ubushushu, obujoliswe kwiikhoyili zomphunga.
Ukunyibilika kweFrost: Ubushushu bunyibilikisa iqabaka eqokelelweyo, ijike ibe ngamanzi, ize iphele.
Ukusetwa kwakhona kweNkqubo: Nje ukuba iqabaka inyibilike, isibali-xesha se-defrost sicima isifudumezi, kwaye umjikelo wokupholisa uqalise kwakhona.
Iindidi ze-Defrost heaters
Zimbini iindidi eziphambili zezifudumezi ezisetyenziswa kwiifriji:

Izifudumezi zoMbane zokuThobeka: Ezi zifudumezi zisebenzisa ukuxhathisa kombane ukwenza ubushushu. Zezona ntlobo zixhaphakileyo kwaye zifumaneka kwiifriji ezininzi zanamhlanje. Izifudumezi zombane zokucima iqhwa zinokuba luhlobo lweribhoni okanye uhlobo lwengcingo, eyilelwe ukunika ukufudumeza okufanayo kwiikhoyili zomphunga.
Izifudumezi zerhasi ezishushu zokunyibilikisa: Le ndlela isebenzisa igesi ecinezelweyo yefriji esuka kwisicinezeli ukuvelisa ubushushu. Irhasi eshushu ilawulwa ngeekhoyili, inyibilika iqabaka njengoko idlula, ivumela umjikelezo okhawulezayo we-defrost. Nangona le ndlela isebenza kakuhle, ayiqhelekanga kwiifriji zasekhaya kunezifudumezi zombane.
