Za kulephera kwachinyengo kwa mafiriji amalonda

     Kulephera kwa firiji yamalonda kumatanthauza mavuto a firiji yomwe ikugwiritsidwa ntchito, osati yokha, ndi zigawo zake zomwe zimayambitsidwa ndi kulephera kosiyanasiyana. Firiji yamalonda ikakonzedwanso, choyamba iyenera kuchotsa cholakwika chabodza ichi, kuti kukonzanso kugwire bwino ntchito. Zotsatirazi zikuwonetsani zomwe zolakwika za firiji yamalonda zimakhala nazo.

       Kugwiritsa ntchito molakwika kabati yozizira, kuyikidwa pamalo osasangalatsa, mpweya woipa, fumbi la condenser lochuluka komanso kusayeretsa nthawi yake, izi zimapangitsa kuti kutentha kwa condenser kusakhale koipa, kotero kuti kuzizira kwa kabati yozizira kumakhala koipa.

Chakudya chochuluka chosungidwa mufiriji, chimalepheretsa mpweya wozizira kuyenda bwino, ndipo kutentha kwa kabati kumakhala kokwera kwambiri. Kutsegula chitseko cha kabati yozizira pafupipafupi, compressor imafunika nthawi yayitali.

        Compressor imakhala yotentha kwambiri ikagwira ntchito, ndipo compressor nthawi zonse imachotsa kutentha komwe kumayamwa ndi refrigerant mu evaporator kudzera mu condenser. Chifukwa chake kutentha kwa chipolopolo cha compressor nthawi zambiri kumakhala madigiri 80.℃mpaka 90℃, chomwe ndi mtundu wa ntchito yake.

        Firiji yoziziritsira siizizira kwambiri, izi zikusonyeza kuti firijiyo ndi yonyowa kwambiri, ndipo kutentha kwake ndi kwakukulu. Chinyezi chingachokere ku chakudya, komanso chingakhale chogwirizana kwambiri ndi kutsegula chitseko, makamaka firiji yokhala ndi chitseko chimodzi ndiyo ingayambitse zinthu zotere. Yankho lake ndi kuchotsa ayezi pamwamba pa firiji, kenako kusintha thermostat kuti muchepetse kutentha mkati mwa firiji.

        Kabati yogwira ntchito yozizira imatulutsa phokoso la madzi, lomwe ndi kayendedwe ka refrigerant mu payipi, pamene madzi akuyenda kupita ku evaporator, momwe alili ndi madzi, madzi a refrigerant amatulutsa phokoso lomveka bwino la madzi, nthawi zina akamatseka, amatha kumveka posachedwa. Izi zili choncho chifukwa chakuti kusakhala ndi mphamvu kwa kayendedwe ka refrigerant komwe kumachitika chifukwa cha, ndi phokoso lachibadwa.

        Kutentha kwa chipolopolo cha firiji, kutentha kwa evaporator mu kabati komwe kumayamwa kutentha ndi kutentha kwa ntchito ya compressor kuli kunja kwa kabati kozizira komwe kumachotsedwa. Pakadali pano, condenser ina ili kumbuyo kwa firiji, ina imabisika m'mbali mwa bokosilo. Kutentha kwabwinobwino, kutentha kwa pamwamba pa condenser kumatha kufika madigiri 50.℃mpaka 60℃Chifukwa chake, kutentha kwa firiji yamalonda ndi chinthu chachibadwa.

        Mufiriji, mphamvu yoziziritsira imakhala yosiyana m'nyengo zosiyanasiyana, firiji ili ndi chotenthetsera cholipirira komanso chosinthira mphamvu, chomwe chimagwiritsidwa ntchito nthawi yozizira pa kabati, chomwe chimayenera kukweza kutentha kwa kabati, kuthetsa kutentha kwa nyengo yozizira komwe kumakhala kochepa, ndipo thermostat siigwira ntchito mosavuta kuti ichititse kuti compressor iyambe kugwira ntchito. M'nyengo yozizira ngati chosinthira ichi sichinatsekedwe, pakhoza kukhala vuto la kuzizira.

       Malinga ndi miyezo ya dziko, kusinthasintha kwa magetsi kwa choziziritsira kumaloledwa kuyambira 187 V mpaka 242 V. Kusakwanira kwa magetsi kapena kulumikizana kwa pulagi ndi soketi ndi kofooka m'magawo onse awiri kungapangitse magetsi owonjezeredwa ku choziziritsira chamalonda kukhala otsika kuposa magetsi ogwirira ntchito, ndipo choziziritsira sichimayamba kapena kuyamba pafupipafupi. Ngati kusinthasintha kwa magetsi kuli kwakukulu kwambiri, ndibwino kuti musagwiritse ntchito.
