Umgomo wokusebenza wesistimu yesiqandisi sokucindezelwa kwesitimu se-air conditioning yemoto
Umgomo wokusebenza wohlelo lwesiqandisi sokucindezelwa kwesitimu se-air conditioning yemoto ikakhulukazi uhlanganisa izinqubo ezine eziyisisekelo: inqubo yokuminyanisa, inqubo yokufingqa, inqubo yokunweba kanye nenqubo yokuhwamuka.
Inqubo yokucindezela : I-compressor ihogela izinga lokushisa eliphansi kanye nesiqandisi segesi esinengcindezi ephansi ohlangothini lwengcindezi ephansi ye-evaporator, iyiminyanise ekushiseni okuphezulu nasesiqandisini esinomfutho ophezulu wegesi, bese siyithumela ku-condenser ukuze iphole. Le nqubo inyusa izinga lokushisa nokucindezela kwesiqandisi.
inqubo yokufingqa : isiqandisi segesi esinezinga lokushisa eliphezulu kanye nomfutho ophezulu wegazi sichithwa isiphephetha-moya nomoya okhiqizwe yimoto ku-condenser, bese sijiya sibe yifriji ewuketshezi ezingeni lokushisa eliphakathi nendawo kanye nokucindezela okukhulu. Indima ye-condenser ukudlulisa ukushisa kwesiqandisi endaweni yangaphandle ukuze sikupholise.
Inqubo yokwandisa : Uma isiqandisi esiwuketshezi sidlula kuvalvu yokunweba noma ishubhu elidonsa kanzima, ingcindezi nezinga lokushisa kwehla kakhulu bese kuba izinga lokushisa eliphansi kanye nomhwamuko omanzi. Le nqubo ibangela ingxenye yesiqandisi ukuba ihwamuke, yenze ingxube ye-gas-liquid elungele ukumunca ukushisa.
inqubo yokuhwamuka : ingxube ye-gas-liquid yesiqandisi ingena ku-evaporator, imunce ukushisa ekalishini, bese ihwamuka ibe isiqandisi esinezinga lokushisa eliphansi kanye ne-low-pressure gaseous refrigerant. I-evaporator iyisishintshi sokushisa esisebenzayo, esisusa ukushisa okumuncwe yisiqandisi ohlelweni lokuhwamuka kwekalishi ngepayipi elingaphakathi, ukuze kuzuzwe umphumela wokupholisa .
Izingxenye zohlelo lwesiqandisi se-air conditioning air conditioning yezimoto zifaka i-compressor, i-condenser, i-valve yokwandisa (noma i-throttle tube), i-evaporator kanye nezinto zokulawula ezihambisanayo. Ndawonye, lezi zingxenye zakha uhlelo lokujikeleza oluvaliwe lapho isiqandisi sigeleza ngokuqhubekayo, siqedela ukuguquka ukusuka kugesi ukuya oketshezini kuya kugesi .
Isimo sokusetshenziswa kwesistimu yesiqandisi sokuminyanisa isitimu se-air conditioning yemoto ngokuyinhloko isistimu ye-air conditioning yangaphakathi yemoto. Ngalesi simiso, isimo somoya semoto singanciphisa ngempumelelo izinga lokushisa enqoleni futhi sinikeze indawo yokushayela ekhululekile.
I-automobile air conditioning steam compression system iyisisetshenziswa esisebenzisa isiqandisi ukuze sijikeleze ohlelweni lokushintshanisa ukushisa, esetshenziselwa kakhulu ukunciphisa izinga lokushisa emotweni. Uhlelo ngokuyinhloko luqukethe izingxenye ezilandelayo: i-compressor, i-condenser, i-valve yokwandisa, i-evaporator kanye namapayipi nama-valve axhuma lezi zingxenye.
Isimiso sokusebenza
Inqubo yokucindezela : I-compressor ihogela izinga lokushisa eliphansi kanye nesiqandisi segesi esinomfutho ophansi ku-evaporator, siyicindezele sibe izinga lokushisa eliphezulu kanye nesiqandisi esinomfutho ophezulu wegesi, bese siyithumela ku-condenser ukuze iphole.
inqubo yokufingqa : izinga lokushisa eliphezulu kanye nomfutho ophakeme wesiqandisi segesi ku-condenser ukuya endaweni yokupholisa (imvamisa umoya noma amanzi) ukukhulula ukushisa, ukujiya kube isiqandisi esiwuketshezi.
inqubo yokwandisa : Uma isiqandisi esiwuketshezi sidlula kuvalvu yokwandisa, ukucindezela nezinga lokushisa kuyehla bese kuba izinga lokushisa eliphansi kanye nomhwamuko omanzi ophansi.
inqubo yokuhwamuka : izinga lokushisa eliphansi kanye nomfutho ophansi womhwamuko omanzi ku-evaporator, umunca ukushisa emotweni, uhwamuke ube esiqandisini esiwugesi, bese uhogelwa futhi yi-compressor ukuqedela umjikelezo wesiqandisi.
esiqandisini
Isiqandisi esivamile i-R-134a (tetrafluoroethane), esimunca ukushisa okuningi lapho siguqulwa sisuka oketshezini sibe igesi ku-evaporator, okuholela ekupholiseni .
Isizinda somlando nentuthuko yezobuchwepheshe
Isimiso esiyisisekelo sesistimu yefriji ye-air conditioning yemoto ifana neyomoya we-air conditioning yasendlini, esebenzisa ukuguqulwa kwesimo sefriji ukuze kufinyelele isiqandisi. Ngokuthuthuka kobuchwepheshe, izinhlelo zesimanje zesimo somoya ezimotweni nazo zifakwe izinzwa ezihlukahlukene kanye nezinhlelo zokulawula ukuze kuzuzwe ukulawulwa kwezinga lokushisa okunembe kakhudlwana kanye nokusebenzisa amandla ngendlela ephumelela kakhudlwana.
