Chokondensa.
Kondensa, yomwe ndi gawo la makina oziziritsira, ndi ya chosinthira kutentha, chomwe chingasinthe mpweya kapena nthunzi kukhala madzi, ndikusamutsa kutentha mu chubu kupita mumlengalenga pafupi ndi chubu mwachangu kwambiri. Ntchito ya kondensa ndi njira yotulutsira kutentha, kotero kutentha kwa kondensa kumakhala kokwera.
Ma condenser ambiri amagwiritsidwa ntchito m'mafakitale opanga magetsi kuti azimitse nthunzi yochokera ku ma turbine. Ma condenser amagwiritsidwa ntchito m'mafakitale oziziritsira kuti azimitse nthunzi yoziziritsira monga ammonia ndi freon. Ma condenser amagwiritsidwa ntchito m'makampani 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.
Gawo la makina la makina oziziritsira, lomwe ndi la chosinthira kutentha, limatha kusintha mpweya kapena nthunzi kukhala madzi, ndikusamutsa kutentha mu chitoliro kupita mumlengalenga pafupi ndi chitoliro mwachangu kwambiri. Ntchito ya kondensa ndi njira yotulutsira kutentha, kotero kutentha kwa kondensa kumakhala kokwera.
Ma condenser ambiri amagwiritsidwa ntchito m'mafakitale opanga magetsi kuti azimitse nthunzi yochokera ku ma turbine. Ma condenser amagwiritsidwa ntchito m'mafakitale oziziritsa kuti azimitse nthunzi yoziziritsa monga ammonia ndi freon. Ma condenser amagwiritsidwa ntchito m'makampani 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 kwa mpweya kapena nthunzi. [1]
mfundo
Mpweya umadutsa mu chubu chachitali (nthawi zambiri chimakulungidwa mu solenoid), zomwe zimapangitsa kuti kutentha kutayike mumlengalenga wozungulira. Zitsulo monga mkuwa, zomwe zimapangitsa kutentha, nthawi zambiri zimagwiritsidwa ntchito kunyamula nthunzi. Pofuna kukonza bwino ntchito ya condenser, ma heat sink okhala ndi mphamvu yabwino kwambiri yoyendetsera kutentha nthawi zambiri amamangiriridwa ku mapaipi kuti awonjezere malo otayira kutentha kuti afulumizitse kutayira kutentha, ndipo mpweya umadutsa mwachangu kudzera mu fan kuti uchotse kutentha.
Mu dongosolo lozungulira la firiji, compressor imapuma nthunzi yoziziritsa yotsika komanso yotsika kuchokera ku evaporator, yomwe imakakamizidwa ndi adiabatic kukhala nthunzi yotentha kwambiri komanso yotsika ndi compressor, kenako imakanikizidwa mu condenser kuti izizire nthawi zonse, ndikutulutsa kutentha kupita ku malo ozizira, kenako kuziziritsidwa mu refrigerant yamadzimadzi yozizira kwambiri. Refrigerant yamadzimadzi imakhala refrigerant yamadzimadzi yotsika kudzera mu valavu yowonjezera adiabatic throttling, imasanduka nthunzi ndikuyamwa kutentha mu mpweya wozizira womwe umazungulira madzi (mpweya) mu evaporator, motero imaziziritsa madzi ozungulira mpweya kuti akwaniritse cholinga choziziritsira, ndipo refrigerant yomwe imatuluka kuchokera ku mpweya wotsika imayamwa mu compressor, kotero kayendedwe kake kamagwira ntchito.
Dongosolo loziziritsira la nthunzi lokhala ndi gawo limodzi limapangidwa ndi zigawo zinayi zazikulu za compressor yoziziritsira, condenser, throttle valve ndi evaporator, zomwe zimalumikizidwa motsatizana ndi mapaipi kuti apange dongosolo lotsekedwa, ndipo refrigerant imazungulira nthawi zonse mu dongosolo, imasintha momwe zinthu zilili, ndikusinthanitsa kutentha ndi dziko lakunja.
Makongoletsedwe
Mu makina oziziritsira, evaporator, condenser, compressor ndi throttle valve ndi magawo anayi ofunikira a makina oziziritsira, momwe evaporator ndi chipangizo chomwe chimatumiza kuchuluka kozizira. Refrigerant imayamwa kutentha kwa chinthu chomwe chikuziziritsidwa kuti chiziziritse. Compressor ndi mtima, womwe umagwira ntchito yopumira, kukanikiza ndi kunyamula nthunzi ya refrigerant. Condenser ndi chipangizo chomwe chimatulutsa kutentha, kusamutsa kutentha komwe kumayamwa mu evaporator pamodzi ndi kutentha komwe kumasinthidwa ndi ntchito ya compressor kupita ku malo ozizira. Valavu ya throttle imagwira ntchito yochepetsa kuthamanga kwa refrigerant, pomwe ikuwongolera ndikulamulira kuchuluka kwa madzi oziziritsira omwe akuyenda mu evaporator, ndipo makinawa amagawidwa m'magawo awiri: mbali ya kuthamanga kwambiri ndi mbali ya kuthamanga kochepa. Mu makina enieni oziziritsira, kuwonjezera pa zigawo zinayi zazikulu zomwe zili pamwambapa, nthawi zambiri pamakhala zida zina zothandizira, monga ma solenoid valves, dispenser, dryer, collectors, fusible plugs, pressure controllers ndi zina, zomwe zimapangidwira kukonza ndalama, kudalirika komanso chitetezo cha ntchito.
Malinga ndi mawonekedwe a condensation, air conditioner ikhoza kugawidwa m'magulu awiri: yoziziritsidwa ndi madzi ndi yoziziritsidwa ndi mpweya, ndipo malinga ndi cholinga chogwiritsira ntchito, ikhoza kugawidwa m'magulu awiri: yoziziritsidwa ndi imodzi ndi yosungidwa mufiriji ndi yotenthetsedwa, mosasamala kanthu za mtundu wa kapangidwe kake, imapangidwa ndi zigawo zazikulu zotsatirazi.
Kufunika kwa condenser kumadalira lamulo lachiwiri la thermodynamics - malinga ndi lamulo lachiwiri la thermodynamics, njira yoyendera yokha ya mphamvu ya kutentha mkati mwa dongosolo lotsekedwa ndi njira imodzi, ndiko kuti, imatha kuyenda kuchokera kutentha kwakukulu kupita kutentha kochepa, ndipo tinthu tating'onoting'ono tomwe timanyamula mphamvu ya kutentha m'dziko la microscopic timangosintha kuchokera ku dongosolo kupita ku chisokonezo. Chifukwa chake, injini yotenthetsera ikalandira mphamvu kuti igwire ntchito, pansi pa mtsinjewo iyeneranso kukhala ndi mphamvu yotulutsa, kotero kuti padzakhala kusiyana kwa mphamvu ya kutentha pakati pa kumtunda ndi kumunsi kwa mtsinje, kuyenda kwa mphamvu ya kutentha kudzatheka, ndipo kuzungulira kudzapitirira.
Chifukwa chake, ngati mukufuna kuti chonyamulira chigwirenso ntchito, choyamba muyenera kumasula mphamvu ya kutentha yomwe sinatulutsidwe kwathunthu, ndipo muyenera kugwiritsa ntchito condenser panthawiyi. Ngati mphamvu ya kutentha yozungulira ili yokwera kuposa kutentha kwa condenser, kuti condenser izizire, ntchito iyenera kuchitika (nthawi zambiri pogwiritsa ntchito compressor). Madzi oundana amabwerera ku mkhalidwe wapamwamba komanso mphamvu ya kutentha yochepa, ndipo ntchito ikhoza kuchitidwanso.
Kusankha kondenser kumaphatikizapo kusankha mawonekedwe ndi chitsanzo, ndipo kumatsimikiza kuyenda ndi kukana kwa madzi ozizira kapena mpweya womwe ukuyenda kudzera mu kondenser. Kusankha mtundu wa kondenser kuyenera kuganizira gwero la madzi am'deralo, kutentha kwa madzi, nyengo, komanso kukula kwa mphamvu yonse yoziziritsira ya makina oziziritsira ndi zofunikira pa kapangidwe ka chipinda choziziritsira. Pansi pa mfundo yodziwira mtundu wa kondenser, malo osamutsira kutentha kwa kondenser amawerengedwa malinga ndi katundu woziziritsira ndi katundu wotentha pa gawo lililonse la kondenser, kuti asankhe chitsanzo cha kondenser yeniyeni.
Kapangidwe ka dongosolo
Pambuyo poyamwa kutentha kwa chinthu chozizira mu evaporator, refrigerant yamadzimadzi imasanduka nthunzi kukhala nthunzi yotentha kwambiri komanso yotsika, imapumidwa ndi compressor, imapanikizidwa kukhala nthunzi yotentha kwambiri komanso yotsika kenako imalowa mu condenser, imatulutsa kutentha kupita ku malo ozizira (madzi kapena mpweya) mu condenser, imasanduka madzi othamanga kwambiri, imakokedwa ndi throttle valve kuti ichepetse kuthamanga ndi kutentha kochepa, kenako imalowanso mu evaporator kuti itenge kutentha ndi nthunzi. Kuti akwaniritse cholinga chozizira. Mwanjira imeneyi, refrigerant mu dongosolo kudzera mu evaporation, compression, condensation, throttling njira zinayi zofunika kuti amalize kuzungulira kwa firiji.
