Panali mnyamata wina amene nyumba yake yoyamba inali ndi firiji yakale yoziziritsa pamwamba yomwe inkafunika kupukuta ndi manja nthawi ndi nthawi. Popanda kudziŵa mmene angachitire zimenezi ndiponso kukhala ndi zododometsa zambiri kuti aiwale nkhani imeneyi, mnyamatayo anaganiza zongonyalanyaza nkhaniyo. Patapita pafupifupi chaka chimodzi kapena ziwiri, madzi oundanawo anadzaza m’chipinda chonsecho, n’kusiya kabowo kakang’ono pakati. Izi sizinamudabwitse kwambiri mnyamatayo popeza kuti ankatha kusungabe chakudya chamadzulo chapa TV chambiri chozizira panthaŵi imodzi m’kutsegula kwakung’ono kuja (magwero ake aakulu a chakudya).
Makhalidwe a nkhaniyi? Kupita patsogolo ndi chinthu chodabwitsa chifukwa pafupifupi mafiriji onse amakono amakhala ndi makina owumitsa madzi kuti atsimikizire kuti chipinda chanu chamufiriji sichikhala madzi oundana. Tsoka ilo, ngakhale machitidwe a defrost pamafiriji apamwamba kwambiri amatha kugwira ntchito bwino, choncho ndi bwino kudziwa momwe dongosololi liyenera kugwirira ntchito komanso momwe mungalikonzere ngati likulephera.
Momwe makina a automatic defrost amagwirira ntchito
Monga mbali ya firiji kuti chipinda cha firiji chizikhala chozizira nthawi zonse pafupifupi 40° Fahrenheit (4° Celsius) ndipo chipinda cha mufirijicho chizikhala chozizira kwambiri pafupifupi 0° Fahrenheit (-18° Celsius), kompresayo imapopa mufiriji wamadzimadzi. m'makoyilo a evaporator a chipangizocho (nthawi zambiri amakhala kuseri kwa gulu lakumbuyo mu chipinda chamufiriji). Pamene refrigerant yamadzimadzi imalowa m'makoyilo a evaporator, imakula kukhala mpweya womwe umapangitsa kuti ma coils azizizira. Makina otenthetsera mpweya amakoka mpweya pamwamba pa zoziziritsa zozizira kenako ndikuzungulira mpweyawo kudzera mufiriji ndi mufiriji.
Mapiritsi a evaporator amasonkhanitsa chisanu pamene mpweya wokokedwa ndi injini ya fan ukudutsa pa iwo. Popanda kuzizira nthawi ndi nthawi, chisanu kapena ayezi amatha kuwundana pamakoyilo omwe amatha kusokoneza kwambiri kayendedwe ka mpweya ndikuletsa firiji kuti zisazizire bwino. Apa ndipamene pulogalamu yamagetsi yamagetsi imayamba kugwira ntchito. Zomwe zili mu dongosololi zimaphatikizapo chotenthetsera cha defrost, thermostat ya defrost, ndi control defrost. Kutengera ndi chitsanzo, kuwongolera kumatha kukhala defrost timer kapena board control defrost. Chotenthetsera chimayatsa chotenthetsera kwa nthawi yayitali pafupifupi mphindi 25 kawiri kapena katatu patsiku kuteteza kuti mafunde a evaporator asaundane. Bolodi lowongolera kutentha limayatsanso chotenthetsera koma chidzawongolera bwino. The defrost thermostat imagwira ntchito yake poyang'anira kutentha kwa makola; pamene kutentha kumatsikira pamlingo wokhazikitsidwa, zolumikizira mu thermostat zimatseka ndikulola kuti voliyumu ipangitse mphamvu chowotcha.
Zifukwa zisanu chifukwa chake dongosolo lanu la defrost silikugwira ntchito
Ngati mafunde a evaporator akuwonetsa zizindikiro za chisanu kapena kuchulukana kwa ayezi, makina owumitsa okhawo mwina sakuyenda bwino. Nazi zifukwa zisanu zomwe zingayambitse:
1. Kuwotcha heater defrost - Ngati chotenthetsera defrost sangathe "kutentha", sizingakhale bwino kwambiri kuziziritsa. Nthawi zambiri mumatha kudziwa kuti chotenthetsera chayaka poyang'ana kuti muwone ngati pali chotupa chowoneka kapena matuza. Mukhozanso kugwiritsa ntchito multimeter kuti muyese chowotcha kuti "kupitiriza" - njira yowonjezera magetsi yomwe ilipo mu gawolo. Ngati chotenthetsera chikuwonetsa kuti sichikuyenda bwino, chigawocho chimakhala cholakwika.
2.Kusagwira ntchito bwino kwa defrost thermostat - Popeza kuti defrost thermostat imatsimikizira nthawi yomwe chotenthetsera chidzalandira magetsi, chotenthetsera chosagwira ntchito chingalepheretse chotenthetsera kuyatsa. Mofanana ndi chotenthetsera, mungagwiritse ntchito multimeter kuyesa thermostat kuti magetsi azipitirirabe, koma muyenera kutero pa kutentha kwa 15 ° Fahrenheit kapena kutsika kuti muwerenge bwino.
3.Faulty defrost timer - Pazitsanzo zokhala ndi chowotchera nthawi, chowerengeracho chimalephera kupita patsogolo pakusintha kwanyengo kapena kutha kutumiza magetsi ku chotenthetsera panthawiyi. Yesani kupititsa patsogolo kuyimba kwa nthawi pang'onopang'ono kuti muchepetse chisanu. Compressor iyenera kutsekedwa ndipo chotenthetsera chiyenera kuyatsa. Ngati chowerengera sichikulola kuti mphamvu yamagetsi ifike pa chotenthetsera kapena chowerengera sichikutuluka mkati mwa mphindi 30, chigawocho chiyenera kusinthidwa ndi china chatsopano.
4.Defective defrost control board - Ngati firiji yanu imagwiritsa ntchito bolodi la defrost kuti liwongolere kuzungulira kwa defrost m'malo mwa timer, bolodi ikhoza kukhala yolakwika. Ngakhale gulu lowongolera silingayesedwe mosavuta, mutha kuliyang'ana kuti muwone ngati likuyaka kapena chigawo chachifupi.
5.Bolodi lalikulu lolephera - Popeza bolodi lalikulu la firiji limayang'anira magetsi ku zigawo zonse za chipangizocho, bolodi lolephera silingathe kulola kuti magetsi atumizidwe ku defrost system. Musanalowe m'malo mwa bolodi lalikulu, muyenera kuletsa zomwe zingayambitse.
