Ntchito ya mapangidwe m'mafiriji apanyumba omwe amagwiritsa ntchito machubu otentha okhala ndi ma fuse awiri

Machubu otenthetsera mufiriji (monga machubu otenthetsera) amagwiritsidwa ntchito makamaka pa: ntchito yoziziritsa: Kusungunula chisanu pa evaporator nthawi zonse kuti kuziziritsa kukhale bwino. Pewani kuzizira: Sungani kutentha pang'ono m'malo ena (monga zisindikizo zapakhomo) kuti madzi a condensate asaundane. Kuwongolera kutentha: Kuthandizira kuyambitsa dongosolo lowongolera kutentha m'malo otsika kwambiri. Machubu otentha ndi zigawo zamphamvu kwambiri. Panthawi yogwira ntchito, amatha kukhala ndi zoopsa chifukwa cha kutentha kwambiri, maulendo afupiafupi kapena magetsi osatha. Chifukwa chake, chitetezo chambiri chimafunika.

Tanthauzo lalikulu la ma fuse awiriMa fuse awiri nthawi zambiri amakhala ophatikiza ma fuse otentha (otayika) ndi ma fuse osinthika (monga ma fuse a bimetallic strip), ndipo ntchito zawo ndi izi: Choyamba, amapereka chitetezo chapawiri, mzere woyamba wa chitetezo (ma fuse osinthika) : Pamene chubu chotenthetsera chikukumana ndi vuto lachilendo chifukwa cha vuto kwakanthawi (monga kufufuta kwachidule) kulumikiza dera. Cholakwikacho chikachotsedwa, chikhoza kukhazikitsidwanso chokha kapena pamanja kuti chipewe kusinthidwa pafupipafupi. Mzere wachiwiri wa chitetezo (fuse yotentha) : Ngati fuse yosinthika ikalephera (monga kumatira kukhudzana), kapena chubu chotenthetsera chikupitilizabe (monga kulephera kuwongolera dera), fusesi yotentha imasungunuka kwathunthu kutentha kwakanthawi (nthawi zambiri 70).℃ku 150℃) imafikira, kudula kwathunthu magetsi kuti ateteze moto kapena chigawo chamoto. Kachiwiri, ndikuthana ndi zolakwika zamitundu yosiyanasiyana, monga kuchuluka kwapano: kuyankhidwa ndi ma fuse osinthika. Kutentha kwachilendo: Kumayankhidwa ndi fuseji ya kutentha (idzachitabe ngakhale kuti panopa ndi yabwino koma kutentha kumapitirira muyezo). Pomaliza, mapangidwe osafunikira amathandizira kudalirika. Fuse imodzi imatha kulepheretsa chitetezo chifukwa cha vuto lake (monga kulephera kuwomba munthawi yake), pomwe fuse iwiri imachepetsa kwambiri zoopsa chifukwa cha kusapanga bwino.
