1. Menene firji defrost hita?
The firji defrosting hita a zahiri dumama jiki, kuma dumama jiki ne a zahiri tsarki baki jiki abu, wanda yana da halaye na sauri dumama, in mun gwada da thermal hysteresis, sosai uniform dumama, dogon zafi radiation canja wurin nisa da kuma sauri zafi musayar gudun. da dai sauransu, bututun dumama yana da rufin ciki da kuma bututu na waje, kuma bututun Layer na ciki za a sanye shi da wayar dumama.
2. Ta yaya firiji ke aiki?
Gabaɗaya, bayan an gama defrosting ɗin da ya gabata, za a haɗa layin launin toka na tuntuɓar mai ƙidayar lokaci da layin orange na lamba, kuma mai ƙidayar lokaci, compressor da fan ɗin za su yi aiki a lokaci guda. Ana haɗa na'ura mai ƙididdigewa da na'urar bushewa a jeri, amma saboda juriya na ciki na lokacin defrost ɗin yana da girma sosai, juriya na ciki na na'urar bushewa zai zama ɗan ƙaramin ƙarfi, don haka yawancin wutar lantarki za a ƙara su zuwa lokacin defrost. Zafin da injin daskarewa zai haifar zai zama kadan. Lokacin da mai ƙididdige ƙididdigewa da kwampreta ke gudana a lokaci guda kuma jimlar tattarawa ta kai sa'o'i 8, ana haɗa layin lambar launin toka mai ƙidayar lokaci da layin orange na lamba. Za a kunna wutar lantarki kai tsaye ta fuse da kuma narkewar da za a iya juyewa. A wannan lokacin, injin daskarewa yana da ɗan gajeren kewayawa ta hanyar sauya yanayin zafin jiki na defrost, kuma mai ƙididdige lokacin zazzagewar zai daina aiki. Lokacin da zafin jiki na evaporator ya tashi zuwa 10-16 ° C bayan da aka tattara sanyi ya narke, tuntuɓar na'urar sarrafa zafin jiki ta cire haɗin da'irar defrost, kuma mai ƙididdigewa ya fara gudu.
