Aliyense wa ife ali ndi firiji panyumba. Ziri zovuta kuganiza kuti zaka pafupifupi 80 zapitazo chipangizo cha m'nyumba ichi sichinayambebe. Koma sikuti aliyense amaganizira za chipangizocho ndi mfundo ya firiji. Koma izi ndizomwe zimakhala zokondweretsa komanso zodziwitsa: Kudziwa momwe firiji ikugwirira ntchito, nthawi zonse imakhala yabwino pokhapokha ngati pali zovuta kapena zowonongeka, komanso kuthandizira kusankha chitsanzo chabwino pamene mukugula.
Kodi firiji imagwira ntchito bwanji?
Ntchito ya firiji yamakono yochokera kunyumba imachokera pa zomwe friji yamagwirira ntchito (nthawi zambiri imakhala freon). Dothi lopaka mafutali limayenda pamsewu wotsekedwa, kusintha kutentha kwake. Pambuyo pofika pamalo otentha (ndipo freon amachokera ku -30 mpaka -150 ° C), imatuluka ndipo imachotsa kutentha kwa mpanda wa evaporator. Zotsatira zake, kutentha mkati mwa chipinda chafupika kukhala pafupifupi 6 ° C.
Zipangizo za friji zimathandizidwa ndi zigawo zikuluzikulu za firiji monga compressor (imayambitsa vuto lofunidwa), evaporator (amatenga kutentha kuchokera mkati mwa chipinda chosungiramo firiji), condenser (kutumiza kutentha kwa chilengedwe) ndi mabowo othamanga (valvegulation valve ndi capillary).
Mosiyana, ziyenera kunenedwa za mfundo ya compressor compressor. Ikonzedwa kuti ilamulire kuchepa kwa dongosolo. Compressor imamangitsa firiji yotuluka m'thupi, imaigwedeza ndi kuyikankhira mu condenser. Pankhaniyi, kutentha kwa freon kumatuluka, ndipo imakhalanso madzi. Compressor ya firiji imagwira ntchito chifukwa cha magetsi, omwe ali mkati mwake. Monga lamulo, osindikizidwa piston compressors amagwiritsidwa ntchito mu firiji.
Choncho, mfundo yoyendetsera firiji ikhoza kufotokozedwa mwachidule monga njira yobwezeramo kutentha kwapakati pa chilengedwe, chifukwa mpweya umene uli m'chipindamo ukukoma. Njira imeneyi imatchedwa "Carnot cycle". Ndiyetu chifukwa chake zinthu zomwe timasungira m'firiji kwa nthawi yayitali sizikuwonongeka chifukwa cha kutentha kosalekeza.
Tiyeneranso kukumbukira kuti m'malo osiyana siyana a firiji, kutentha ndi kosiyana, ndipo izi zingagwiritsidwe ntchito kusunga zinthu zosiyanasiyana. Mu firiji zamakono zamakono monga mbali ndi mbali zimakhala zogawidwa bwino m'madera: ndifriji yowonjezera, "zero zone" (biofresh) nyama, nsomba, tchizi, sausages ndi masamba, firiji ndi malo otchedwa frost-zone. Chotsatirachi chimakhala chofulumira kwambiri (mkati mwa mphindi zingapo) kuzizira kwambiri mpaka -36 ° C. Zotsatira zake ndizo, mawonekedwe a kristalline a mawonekedwe osiyana, pomwe zinthu zina zothandiza zimasungidwa kusiyana ndi kuzizira.
Kodi firiji imagwira ntchito bwanji?
Mafiriji opanda dongosolo la chisanu amagwira ntchito mofanana, koma pali kusiyana kulipo m'machitidwe osokoneza. Maofesi oyambirira a firiji omwe ali ndi mtundu wotsikira wa evaporator ayenera kuwonedwa nthawi ndi nthawi, kuti chisanu, chomwe chimakhala pa khoma la chipinda, sichimasokoneza ntchitoyi.
Simukusowa kudandaula ndi izi ngati firiji yanu ili ndi njira yodziwiratu. Chifukwa cha kuyendayenda kwa mpweya wozizira mkati mwa chipinda, chinyezi, chomwe chimakhazikika pamakoma, chimayambira ndikukwera mu poto, kumene imatulukanso.
Mafiriji amadziwa kuti chisanu ndi zipangizo za mbadwo watsopanowu, zomwe zimagwiritsidwa ntchito mosavuta, kusiyana ndi zitsanzo zakale zotsalira. Iwo ali ochepa mphamvu kwambiri, ndipo kuzizira kwa zinthu mwa iwo kumachitika mofanana kwambiri. Komabe, amakhalanso ndi zofooka zawo, pogwiritsa ntchito mfundo zomwe zafotokozedwa pamwambapa. Chifukwa chakuti chipindacho chimayendayenda nthawi zonse, zimatengera chinyezi kuchokera ku chakudya, chomwe chimatha. Choncho, muzidziwitso zachisanu ziyenera kusungidwa muzitsulo zatsekedwa.
Tsopano, podziwa momwe mungagwiritsire ntchito firiji, simudzakhala ndi vuto posankha ndi kugula chipangizo chatsopano ndi ntchito yake.
