Mfundo yogwirira ntchito yoziziritsa mpweya m'galimoto pogwiritsa ntchito nthunzi
Mfundo yogwirira ntchito ya makina oziziritsira mpweya wa nthunzi m'magalimoto imaphatikizapo njira zinayi zazikulu: njira yochepetsera mpweya, njira yoziziritsira mpweya, njira yokulitsa mpweya, ndi njira yotulutsira mpweya.
Njira yokanikizira: Compressor imapumira firiji yotsika komanso yotsika ya gasi kumbali yotsika ya evaporator, kuifinyira mu firiji yotsika komanso yotsika kwambiri ya gasi, kenako n’kuitumiza ku condenser kuti izizire. Njirayi imawonjezera kutentha ndi kupsinjika kwa refrigerant.
Njira yoziziritsira: choziziritsira cha mpweya chotentha kwambiri komanso chopanikizika kwambiri chimasungunuka ndi fani ndi mphepo yopangidwa ndi galimoto yomwe ili mu choziziritsira, ndikusungunuka kukhala choziziritsira chamadzimadzi pa kutentha kwapakati komanso kupanikizika kwakukulu. Ntchito ya choziziritsira ndi kusamutsa kutentha kwa choziziritsira kupita kumalo akunja kuti chiziziritse .
Njira yofutukula: Pamene choziziritsira chamadzimadzi chimadutsa mu valavu yofutukula kapena chubu chopondera, kuthamanga ndi kutentha kumatsika kwambiri ndipo kumakhala kutentha kochepa komanso nthunzi yonyowa yotsika. Njirayi imapangitsa kuti gawo la choziziritsiracho liziphwanyika, ndikupanga chisakanizo cha gasi ndi madzi chokonzeka kuyamwa kutentha.
Njira yotulutsira mpweya: chisakanizo cha gasi ndi madzi cha refrigerant chimalowa mu evaporator, chimayamwa kutentha komwe kuli mu ngolo, ndikusanduka chinyontho kukhala firiji ya gasi yotsika kutentha komanso yotsika mphamvu. Evaporator ndi chosinthira kutentha chogwira ntchito bwino, chomwe chimachotsa kutentha komwe kumayamwa ndi refrigerant mu ndondomeko yotulutsira mpweya kuchokera mu ngolo kudzera mu chitoliro chamkati, kuti chikwaniritse zotsatira zoziziritsa .
Zigawo za makina oziziritsira mpweya wa m'galimoto monga compressor, condenser, valavu yowonjezera (kapena chubu chopopera), evaporator ndi zinthu zina zowongolera. Pamodzi, zigawozi zimapanga makina otsekedwa omwe firiji imayenda mosalekeza, ndikumaliza kusintha kuchokera ku mpweya kupita ku madzi kupita ku mpweya.
Njira yogwiritsira ntchito makina oziziritsira mpweya wa m'galimoto pogwiritsa ntchito nthunzi makamaka ndi makina oziziritsira mpweya wamkati mwa galimoto. Kudzera mu makinawa, makina oziziritsira mpweya a m'galimoto amatha kuchepetsa kutentha kwa galimotoyo ndikupereka malo abwino oyendetsera galimoto.
Dongosolo loziziritsira mpweya woziziritsa m'galimoto ndi chipangizo chomwe chimagwiritsa ntchito refrigerant kuti chizizungulira mu dongosololi kuti chisinthe kutentha, chomwe chimagwiritsidwa ntchito kwambiri kuchepetsa kutentha m'galimoto. Dongosololi limapangidwa makamaka ndi zigawo izi: compressor, condenser, expansion valve, evaporator ndi mapaipi ndi ma valve olumikiza zigawozi.
Mfundo yogwirira ntchito
Njira yokanikizira: Compressor imapumira firiji yotsika komanso yotsika ya gaseous mu evaporator, kuifinya mu firiji yotsika komanso yotsika kwambiri ya gaseous, kenako nkuyitumiza ku condenser kuti izizire.
Njira yoziziritsira: kutentha kwambiri ndi mpweya woipa kwambiri mu condenser kupita ku malo ozizira (nthawi zambiri mpweya kapena madzi) kuti atulutse kutentha, ndikuzizira kukhala firiji yamadzimadzi.
Njira yofutukula: Pamene firiji yamadzimadzi imadutsa mu valavu yofutukula, kuthamanga ndi kutentha kumachepa ndikukhala kutentha kochepa komanso nthunzi yonyowa yotsika.
Njira yothira mpweya: kutentha kochepa komanso mpweya wonyowa wochepa kulowa mu evaporator, umayamwa kutentha mgalimoto, umasanduka mpweya wozizira, kenako umapumidwanso ndi compressor kuti amalize kuzizira.
firiji
Chosungiramo zinthu chofala kwambiri mufiriji ndi R-134a (tetrafluoroethane), chomwe chimatenga kutentha kwambiri chikasinthidwa kuchoka pamadzimadzi kukhala mpweya mu evaporator, zomwe zimapangitsa kuti kuzizire.
Mbiri yakale ndi chitukuko cha ukadaulo
Mfundo yaikulu ya makina oziziritsira mpweya wa m'galimoto ndi yofanana ndi ya makina oziziritsira mpweya wa m'nyumba, omwe amagwiritsa ntchito kusintha kwa momwe makina oziziritsira mpweya amakhalira kuti aziziziritsa. Ndi chitukuko cha ukadaulo, makina oziziritsira mpweya wa m'galimoto amakono alinso ndi masensa osiyanasiyana ndi makina owongolera kuti azitha kuwongolera kutentha molondola komanso kugwiritsa ntchito mphamvu moyenera.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
