Kodi chotenthetsera galimoto ndi chiyani?
CHIKONDI CHA MAGOLOMO NDICHO CHIGAWO CHAPADERA CHA makina oziziritsira mpweya, ndi cha mtundu wa chosinthira kutentha, ntchito yake ndikuziziritsa firiji yotenthetsera mpweya komanso yothamanga kwambiri yomwe imatuluka mu compressor kupita kumadzimadzi, kudzera mu kutentha komwe kumataya kutentha, kutulutsa kutentha kuti kuziziritse mkati mwa galimoto.
Youdaoplaceholder0 Ntchito zoyambira za condenser
Chotenthetsera cha magalimoto ndi gawo lofunikira kwambiri la makina oziziritsira mpweya ndipo chimagwira ntchito zotsatirazi:
Youdaoplaceholder0 Kusintha kwa kutentha : Choziziritsira cha mpweya chotentha kwambiri komanso chopanikizika kwambiri (monga R134a, ndi zina zotero) chomwe chimatuluka mu compressor chimasungunuka kukhala choziziritsira chamadzimadzi kudzera mu kusinthana kutentha ndi mpweya wakunja ndi chotenthetsera kutentha.
Youdaoplaceholder0 Kulamulira kuthamanga kwa mpweya: Panthawi yonyowa, kuthamanga kwa mpweya mufiriji kumachepa pang'onopang'ono kuchokera ku mphamvu yayikulu kuti pakhale zinthu zomwe zimapangitsa kuti kutentha kuyambe kuyamwa.
Youdaoplaceholder0 Kulamulira kutentha : Mwa kutulutsa kutentha, zimaonetsetsa kuti firiji ifika kutentha koyenera isanalowe mu evaporator, motero imayamwa bwino kutentha kuchokera mgalimoto.
Youdaoplaceholder0 Mfundo yogwirira ntchito ndi kapangidwe kake
Kondensa imakwaniritsa kayendedwe ka firiji kudzera mu njira iyi:
Youdaoplaceholder0 Njira yosinthira gawo : Pamene firiji ikuyenda kudzera mu chubu cha mkuwa (kapena aluminiyamu), imasintha kuchoka pa mkhalidwe wa mpweya kupita ku mkhalidwe wamadzimadzi, ndipo kutentha kobisika komwe kumatulutsidwa kumayendetsedwa mofulumira kupita mumlengalenga ndi zipsepse za aluminiyamu.
Youdaoplaceholder0 Kukakamiza convection : Pogwiritsa ntchito mpweya wachilengedwe womwe ukuyenda kapena fan yamagetsi kuti ichititse kutentha kutayike ndikufulumizitsa kugwira ntchito bwino kwa kusinthana kutentha.
Youdaoplaceholder0 Kapangidwe ka zigawo zambiri : Mitundu yambiri imagwiritsa ntchito kapangidwe kofanana ka kayendedwe ka madzi, kokhala ndi mizere ingapo ya machubu athyathyathya ndi zipsepse za louver, kuti iwonjezere malo otayira kutentha.
Condenser (Condenser), yomwe ndi gawo la makina oziziritsira, ndi mtundu wa chosinthira kutentha chomwe chimasintha mpweya kapena nthunzi kukhala madzi ndikusamutsa kutentha kuchokera mu chubu kupita mumlengalenga pafupi ndi chubu mwachangu. Kagwiridwe ka ntchito ka condenser ndi njira yochokera ku exothermic, kotero kutentha kwa condenser nthawi zonse kumakhala kokwera.
Malo opangira magetsi amagwiritsa ntchito ma condenser ambiri kuti azimitse nthunzi yotuluka m'ma turbine. Mu malo oziziritsira, ma condenser amagwiritsidwa ntchito kuti azimitse nthunzi yoziziritsira monga ammonia ndi Freon. Ma condenser amagwiritsidwa ntchito mumakampani opanga petrochemical kuti azimitse ma hydrocarbon ndi nthunzi zina za mankhwala. Mu njira yothira, chipangizo chomwe chimasintha nthunzi kukhala madzi chimatchedwanso condenser. Ma condenser onse amagwira ntchito pochotsa kutentha kuchokera ku mpweya kapena nthunzi.
Mpweya umadutsa mu chubu chachitali (nthawi zambiri chimakulungidwa kukhala solenoid), zomwe zimapangitsa kuti kutentha kutuluke mumlengalenga wozungulira. Zitsulo monga mkuwa, zomwe zimakhala ndi mphamvu yotenthetsera kutentha kwambiri, nthawi zambiri zimagwiritsidwa ntchito kunyamula nthunzi. Kuti condenser igwire bwino ntchito, ma heat sinks omwe ali ndi mphamvu yabwino kwambiri yotenthetsera kutentha nthawi zambiri amamangiriridwa ku mapaipi kuti awonjezere malo otenthetsera kutentha ndikufulumizitsa kutenthetsera kutentha. Nthawi yomweyo, mafani amagwiritsidwa ntchito kufulumizitsa kutenthetsera kwa mpweya ndikunyamula kutentha.
Mu makina oziziritsira mpweya, compressor imayamwa nthunzi yoziziritsira mpweya yotsika komanso yotsika kuchokera ku evaporator. Pambuyo pokakamizidwa ndi compressor, imakhala nthunzi yotentha kwambiri komanso yotsika, yomwe imakanikizidwa mu condenser kuti izizire mpweya nthawi zonse ndikutulutsa kutentha kupita ku malo ozizira. Pomaliza, imaziziritsidwa kukhala madzi ozizira kwambiri. Madzi oziziritsira mpweya amadutsa mu adiabatic throttling kudzera mu valavu yowonjezera kuti ikhale madzi otsika. Mu evaporator, imasanduka nthunzi ndikuyamwa kutentha kuchokera ku madzi oziziritsira mpweya (mpweya), motero imaziziritsa madzi oziziritsira mpweya kuti ikwaniritse cholinga choziziritsira mpweya. Refrigerant yotsika yomwe imatuluka imakokedwa mu compressor, ndipo kuzunguliraku kumapitirira.
Dongosolo loziziritsira la nthunzi lokhala ndi gawo limodzi limapangidwa ndi zigawo zinayi zazikulu: compressor yoziziritsira, condenser, valavu yolumikizira ndi evaporator. Amalumikizidwa motsatizana ndi mapaipi kuti apange dongosolo lotsekedwa. Refrigerant imazungulira nthawi zonse mu dongosolo, imadutsa mu kusintha kwa momwe zinthu zilili komanso imasinthasintha kutentha ndi dziko lakunja.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
