Mbali Zam'kati mwa Firiji Yanyumba

Firiji ya m’nyumba ndi imene imapezeka pafupifupi m’nyumba zonse zosungiramo zakudya, ndiwo zamasamba, zipatso, zakumwa, ndi zina zambiri. Nkhaniyi ikufotokoza mbali zofunika za firiji komanso ntchito yake. Munjira zambiri, firiji imagwira ntchito mofanana ndi momwe makina oziziritsira mpweya amagwirira ntchito. Firiji ikhoza kugawidwa m'magulu awiri: mkati ndi kunja.

Zigawo zamkati ndi zomwe zimagwira ntchito yeniyeni ya firiji. Zina mwazigawo zamkati zili kumbuyo kwa firiji, ndipo zina zili mkati mwa chipinda chachikulu cha firiji. Zigawo zazikulu zoziziritsa zikuphatikizapo (chonde tchulani chithunzi pamwambapa): 1) Refrigerant: Refrigerant imayenda m'madera onse a mkati mwa firiji. Ndi refrigerant yomwe imatulutsa kuziziritsa mu evaporator. Imayamwa kutentha kuchokera muzinthu zomwe zimaziziritsidwa mu evaporator (chiller kapena mufiriji) ndikuponyera mumlengalenga kudzera mu condenser. Refrigerant imapitilirabe kuzungulira mbali zonse zamkati za firiji mozungulira. 2) Compressor: Compressor ili kumbuyo kwa firiji komanso pansi. Compressor imayamwa refrigerant kuchokera mu evaporator ndikuitulutsa pamphamvu komanso kutentha. Compressor imayendetsedwa ndi mota yamagetsi ndipo ndiye chida chachikulu chogwiritsa ntchito mphamvu mufiriji. 3) Condenser: Condenser ndi koloko yopyapyala yamkuwa yomwe ili kumbuyo kwa firiji. Refrigerant yochokera ku kompresa imalowa mu condenser komwe imakhazikika ndi mpweya wa mumlengalenga motero kutaya kutentha komwe kumalowetsedwa mu evaporator ndi kompresa. Kuti muwonjezere kutentha kwa condenser, imachotsedwa kunja. 4) Valve yowonjezera kapena capillary: Refrigerant yomwe imachoka mu condenser imalowa mu njira yowonjezera, yomwe ndi chubu cha capillary ngati mafiriji apakhomo. Capillary ndi chubu chopyapyala chamkuwa chopangidwa ndi kuchuluka kwa kuzungulira kwa koyilo yamkuwa. Pamene firiji imadutsa mu capillary kuthamanga kwake ndi kutentha kumatsika mwadzidzidzi. 5) Evaporator kapena chiller kapena mufiriji: Firiji pa kuthamanga kwambiri ndi kutentha amalowa mu evaporator kapena mufiriji. Evaporator ndi chosinthira kutentha chopangidwa ndi machubu angapo amkuwa kapena aluminiyamu. M'mafiriji apanyumba mitundu ya mbale ya evaporator imagwiritsidwa ntchito monga momwe tawonera pamwambapa. Refrigerant imatenga kutentha kuchokera kuzinthu zomwe zikaziziziritsidwa mu evaporator, zimasanduka nthunzi kenako zimayamwa ndi kompresa. Kuzungulira uku kumangobwerezabwereza. 6) Chida chowongolera kutentha kapena thermostat: Kuwongolera kutentha mkati mwa firiji pali thermostat, yomwe sensor yake imalumikizidwa ndi evaporator. Kuyika kwa thermostat kumatha kuchitidwa ndi chozungulira chozungulira mkati mwa chipinda cha firiji. Pamene kutentha kwayikidwa kufika mkati mwa firiji thermostat imayimitsa magetsi ku compressor ndi compressor imayima ndipo kutentha kutsika pansi pa mlingo wina kumayambiranso kupereka kwa compressor. 7) Dongosolo la defrost: Dongosolo la defrost la firiji limathandiza kuchotsa ayezi ochulukirapo pamwamba pa evaporator. Dongosolo la defrost limatha kuyendetsedwa pamanja ndi batani la thermostat kapena pali makina odziwikiratu okhala ndi chotenthetsera chamagetsi ndi chowerengera nthawi. Izo zinali zigawo zina za mkati mwa firiji ya m'nyumba.
