Mafiriji amagwiritsidwa ntchito kwambiri popangira nyumba ndi malonda kuti athandizire kusunga ndi kusunga zakudya zatsopano kwa nthawi yayitali, komanso kupewa kuwonongeka kuti zisawonongeke.Ndi firiji yamalonda, zakudya zabwino zimatha kusungidwa kwa nthawi yayitali, makamaka m'malo ogulitsira kapena malo odyera, amafunikira kusunga zakudya ndi zakumwa zambiri, kukhala ndi firiji kumatha kuonetsetsa kuti ali ndi zinthu zokwanira zothandizira makasitomala awo.Komabe, ngakhale tili ndi firiji, kuwonongeka kwina kosafunikira nthawi zina kumachitikabe chifukwa chogwiritsa ntchito molakwika kapena kusamalidwa bwino.Kuti titsimikizire kuti zida zathu zamafiriji zikuyenda bwino, tiyenera kuphunzira mfundo zake zogwirira ntchito kuti zithandizire kukonza bwino.
Chifukwa Chake Kuphunzira Mfundo Yogwira Ntchito ya Firiji Ndi Yofunikira
Kodi refrigeration system imagwira ntchito bwanji?Mfundo yogwirira ntchito ya firiji imachokera ku kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake, komwe kumakhala ndi refrigerant yomwe imakhala yotsekedwa mkati mwake ndipo imakankhira kuchoka ku evaporator kupita ku condenser mumitundu yosiyanasiyana.Dongosolo lotereli likugwira ntchito ndi cholinga choziziritsa kutentha mu gawo losungirako.Kudziwa njira yanufiriji yamalondazida zimagwira ntchito ndizothandiza kuti mudziwe kutentha kuti muyeretse bwino ndikusunga firiji.Pomvetsetsa mfundo yogwirira ntchito komanso chidziwitso cha firiji, mudzapindula ndi luso la zida zanu.Mwachitsanzo, kuphunzira zomwe zimayika firiji yanu yamalonda pamalo olowera mpweya kungathandize kupewa kugwira ntchito mopambanitsa ndikuchepetsa kugwiritsa ntchito mphamvu.
Ndi Zigawo Zotani Zomwe Zimaphatikizidwa mu Refrigeration System?
Monga tafotokozera pamwambapa, firiji ndi dongosolo lozungulira lomwe limaphatikizapo zigawo zina zamakina ndi zigawo zina, zomwe zimaphatikizapo compressor, condenser, expansion / throttle valve, evaporator, etc. Kuwonjezera apo, refrigerant ndi chinthu chofunikira kwambiri kuti chisamutse kutentha kwa mkati kupita ku condenser kunja.Chigawo chilichonse chili ndi ntchito yake yeniyeni yokankhira refrigerant kuti iyende mozungulira mu dongosolo ili lozungulira, ndipo refrigerant imasandulika mozungulira kukhala mpweya kapena madzi, kayendedwe kameneka kangapangitse kuti kuzizira kugwetse kutentha kosungirako.
Tiyeni tiphunzire zambiri za zigawo za firiji.
Compressor
Compressor imatengedwa ngati mphamvu yokankhira firiji kuti iyende mufiriji, ndipo chigawo ichi chimaphatikizapo injini yojambula nthunzi ya refrigerant kuchokera ku evaporator ndikuyiyika mu silinda kuti ikweze kutentha ndi kupanikizika, kotero kuti mpweya wa refrigerant ukhoza kutsekedwa mosavuta ndi mpweya ndi madzi ndi kutentha kwa chipinda pamene ukankhira ku condenser.
Condenser
Condenser ndi chipangizo chosinthira kutentha, chomwe chimaphatikizapo ma chubu ndi zipsepse zomwe zimakhazikika kumbuyo kapena mbali za firiji.Pamene mpweya wa refrigerant uli ndi kuthamanga kwakukulu ndi kutentha ukudutsa apa, umasinthidwa kukhala mawonekedwe amadzimadzi ndi kutentha kwa chipinda, koma refrigerant yamadzimadzi imabwerabe ndi kuthamanga kwambiri.
Vavu yowonjezera
Refrigerant yamadzi isanalowe mu evaporator, kuthamanga kwake ndi kutentha kwake zimakokedwa mpaka kumachulukitsidwe ndi valavu yakukulitsa ikadutsa.Kutsika kwadzidzidzi kwa kutentha ndi kupanikizika kungayambitse firiji.
Evaporator
Evaporator ndi chipangizo chosinthira kutentha.The refrigerant madzi ndi kutentha otsika ndi kuthamanga kuthamanga mu chipangizo ichi kuti amasanduka nthunzi nthunzi, amene amatenga kutentha kwa mpweya mu firiji, ndondomeko zimenezi zimathandiza kuti cholinga chachikulu cha kuzizira pansi zakudya zosungidwa ndi zakumwa.Kutsika kwa refrigerant mu evaporator, kumachepetsa kutentha kwa zinthu zosungidwa.
Kodi Refrigeration System Imagwira Ntchito Motani?
Zomwe tazitchula pamwambapa zimalumikizidwa ndi machubu kuti apange dongosolo lozungulira.Dongosololi likamagwira ntchito, kompresa imakoka mpweya wocheperako komanso mpweya wocheperako wopangidwa ndi evaporator mu silinda.Pamene kupanikizika (kutentha kumakweranso) kumakhala kwakukulu pang'ono kusiyana ndi kupanikizika kwa condenser, mpweya wothamanga kwambiri wa refrigerant mu silinda umatumizidwa ku condenser.(kotero, kutenga udindo wa psinjika ndi kufala kwa refrigerant kompresa) mkati condensing refrigerant wa kutentha kwambiri ndi kuthamanga nthunzi ndi otsika kutentha mpweya (kapena madzi) pa firiji kutentha kutengerapo ndi condensation wa madzi refrigerant, madzi refrigerant. pambuyo kutambasuka valavu kuzirala (tonde) mu evaporator, mkati evaporator zimatenga kutentha ndiyeno vaporizing chinthu kuti utakhazikika.Mwanjira imeneyi, chinthu utakhazikika utakhazikika ndi nthunzi refrigerant ndi kuyamwa kutali ndi kompresa, kotero mu firiji dongosolo kudzera psinjika, condensation, kutambasuka, evaporation anayi njira kumaliza mkombero.
