Chingwe Chotenthetsera Chitseko cha Freezer Defrost

Chotenthetsera chitseko cha freezer ndi chinthu chotenthetsera chopangidwa mwapadera, chomwe chimagwiritsidwa ntchito kwambiri m'mafiriji, mafiriji ndi zida zina zamafiriji. The defrost khomo chimango chotenthetsera waya ntchito yaikulu ndi kusungunula chisanu wosanjikiza wopangidwa pamwamba pa evaporator kudzera Kutentha, motero kuonetsetsa ntchito mosalekeza ndi moyenera zipangizo firiji. Waya wolukidwa wa chitseko ichi nthawi zambiri amapangidwa ndi nickel-chromium alloy, chinthu chomwe chimatengedwa kwambiri chifukwa cha kukana kwa dzimbiri komanso mphamvu yamagetsi.

Panthawi yogwira ntchito mufiriji, evaporator, chifukwa cha kutentha kwake kochepa kwambiri, imayambitsa nthunzi yamadzi mumlengalenga kuti ikhale pamwamba pake ndipo pang'onopang'ono imapanga chisanu. M'kupita kwa nthawi, kukhuthala kwa chisanu kumawonjezeka mosalekeza, zomwe sizimangokhudza kusintha kwa kutentha kwa evaporator komanso kungayambitse kuchepa kwa kuzizira kapena kulephera kwa zida. Pofuna kuthana ndi vutoli, mafiriji amakono nthawi zambiri amakhala ndi makina osungunulira. Pamene anamanga-sensa detects kuti makulidwe a chisanu wosanjikiza kuposa anaika, dongosolo yambitsa zitsulo zotayidwa kuluka defrost Kutentha waya kuchita Kutentha ntchito. Panthawiyi, waya wotenthetsera chitseko amatulutsa kutentha kokwanira kusungunula chisanu m'madzi, chomwe chimachotsedwa mu chipangizocho kudzera mu ngalande. Chiwombankhanga chikasungunuka kwathunthu, waya wotenthetsera pakhomo adzasiya kugwira ntchito, ndipo firiji idzabwerera nthawi yomweyo kumalo ake ozizira, kupitiriza kupatsa ogwiritsa ntchito firiji yokhazikika kapena malo ozizira.
