Umgomo wokusebenza wohlelo lokuqandisa umoya olucindezelwa ngomusi we-air conditioning yezimoto
Isimiso sokusebenza sohlelo lokuqandisa umoya olucindezelwa ngomusi we-air conditioner yezimoto sihlanganisa izinqubo ezine eziyisisekelo: inqubo yokucindezela, inqubo yokufinyeza, inqubo yokwandisa kanye nenqubo yokuhwamuka.
Inqubo yokucindezela: I-compressor ihogela i-refrigerant yegesi ephansi kanye nengcindezi ephansi ohlangothini lokucindezela okuphansi kwe-evaporator, iyicindezele ibe yi-refrigerant yegesi ephansi kanye nengcindezi ephezulu, bese iyithumela ku-condenser ukuze iphole. Le nqubo ikhulisa izinga lokushisa kanye nengcindezi ye-refrigerant.
Inqubo yokujiya: i-refrigerant yegesi enokushisa okuphezulu kanye nokucindezela okuphezulu iyachithwa yifeni nomoya okhiqizwa yimoto ekwi-condenser, bese iqiniswa ibe yi-refrigerant ewuketshezi ekushiseni okuphakathi kanye nokucindezela okuphezulu. Indima ye-condenser ukudlulisa ukushisa kwe-refrigerant endaweni yangaphandle ukuze iphole.
Inqubo yokwandisa: Lapho isiqandisi soketshezi sidlula ku-valve yokwandisa noma ipayipi le-throttle, ingcindezi kanye nokushisa kwehla kakhulu bese kuba yi-temperature ephansi kanye nomhwamuko omanzi ophansi. Le nqubo ibangela ukuthi ingxenye yesiqandisi iphele, kwakhiwe ingxube yegesi noketshezi elungele ukumunca ukushisa.
Inqubo yokuhwamuka: ingxube yegesi noketshezi lwe-refrigerant ingena ku-evaporator, imunce ukushisa okusenqoleni, bese ihwamuka ibe yi-refrigerant yegesi enokushisa okuphansi kanye nokucindezela okuphansi. I-evaporator iyi-heat exchanger esebenza kahle, esusa ukushisa okumuncwa yi-refrigerant enqubweni yokuhwamuka kusuka enqoleni ngepayipi langaphakathi, ukuze kufezwe umphumela wokupholisa.
Izingxenye zesistimu yokuqandisa yokucindezela umusi wemoto zifaka i-compressor, i-condenser, i-expansion valve (noma i-throttle tube), i-evaporator kanye nezinto zokulawula ezihambisanayo. Zihlangene, lezi zingxenye zakha uhlelo lokujikeleza oluvaliwe lapho i-refrigerant igeleza khona njalo, iqedela ukuguquka kusuka kugesi iye koketshezi iye kugesi .
Isimo sokusetshenziswa kohlelo lokuqandisa umoya olucindezelwa ngomusi lwe-air conditioner yezimoto ikakhulukazi uhlelo lwangaphakathi lwe-air conditioner yezimoto. Ngalesi simiso, i-air conditioner yemoto inganciphisa ngempumelelo izinga lokushisa enqoleni futhi inikeze indawo yokushayela ekhululekile.
Uhlelo lokuqandisa umoya olusebenzisa umshini wokupholisa umusi wemoto luyidivayisi esebenzisa i-refrigerant ukujikeleza ohlelweni ukuze kushintshwe ukushisa, ikakhulukazi esetshenziselwa ukunciphisa izinga lokushisa emotweni. Uhlelo luqukethe izingxenye ezilandelayo: i-compressor, i-condenser, i-expansion valve, i-evaporator kanye namapayipi nama-valve axhumanisa lezi zingxenye.
Isimiso sokusebenza
Inqubo yokucindezela: I-compressor idonsa isiqandisi segesi esinokushisa okuphansi kanye nesinomfutho ophansi ku-evaporator, isicindezele sibe yi-refrigerant yegesi esinokushisa okuphezulu kanye nesinomfutho ophakeme, bese isithumela ku-condenser ukuze iphole.
Inqubo yokujiya: ukushisa okuphezulu kanye nesiqandisi segesi esinomfutho ophezulu ku-condenser kuya endaweni yokupholisa (ngokuvamile umoya noma amanzi) ukuze kukhishwe ukushisa, kujiya kube yi-refrigerant ewuketshezi.
Inqubo yokwandisa: Lapho isiqandisi soketshezi sidlula ku-valve yokwandisa, ingcindezi kanye nokushisa kwehla futhi kube yi-temperature ephansi kanye nomhwamuko omanzi ophansi.
Inqubo yokuhwamuka: ukushisa okuphansi kanye nomhwamuko omanzi ongaphansi komfutho ophansi ungene ku-evaporator, umunce ukushisa emotweni, uhwamuke ube yi-refrigerant yegesi, bese uphefumulwa futhi yi-compressor ukuze kuqedwe umjikelezo wokuqandisa.
isiqandisi
Isiqandisi esivamile yi-R-134a (tetrafluoroethane), esimunca ukushisa okuningi lapho siguqulwa kusuka koketshezi sibe yigesi ku-evaporator, okuholela ekupholeni.
Isizinda somlando kanye nentuthuko yezobuchwepheshe
Isimiso esiyisisekelo sohlelo lokuqandisa umoya wezimoto sifana nesohlelo lokuqandisa umoya wekhaya, olusebenzisa ushintsho lwesimo sefriji ukuze kufezwe ukuqandisa. Ngokuthuthuka kobuchwepheshe, izinhlelo zesimanje zokupholisa umoya wezimoto nazo zihlonyiswe ngezinzwa ezahlukahlukene nezinhlelo zokulawula ukuze kufezwe ukulawulwa kokushisa okunembile kanye nokusetshenziswa kwamandla okuphumelelayo.
