Amafutha e-air conditioner yemoto - ukukhetha ngokuvumelana nayo yonke imithetho
Okuqukethwe
Abashayeli bezimoto abaningi ngokwabo bazama ukuxazulula inkinga yokusebenza kwe-air conditioning system. Kulokhu, nakanjani udinga ukunquma ukuthi yimaphi uwoyela we-auto-conditioner ongawakhetha ukuze ugweme ukuwohloka ngokuzayo.
Amafutha e-air conditioning - ungalimazi kanjani?
Kulezi zinsuku, ezindaweni ezidayisa izimoto kunezinhlobonhlobo zamafutha ama-air conditioner ezimotweni. Ukukhethwa kwalesi sici kufanele kuthathwe ngomthwalo wemfanelo, ngoba lokhu kukude nokuncane, njengoba kubonakala ekuqaleni. Kuyaphawuleka ukuthi kuma-air conditioners emoto, ngokungafani nama-air conditioner wezinye izinhlelo zesiqandisi nokufakwa, zisebenzisa amashubhu e-aluminium nezimpawu zenjoloba zokufakwa, okuthi, uma ziphathwa kabi noma zigcwaliswe ukwakheka okungalungile, zingalahlekelwa izakhiwo zazo zomzimba futhi zihluleke.
Uma ngephutha uxuba izinhlobo ezimbili ezihlukene zikawoyela, nakanjani kuzodala ukugeleza emigqeni yemoto yakho. Futhi kakade le nkinga ingaxazululwa kuphela enkonzweni yemoto, futhi ukuxilongwa nokuhlanza okunjalo kuzobiza umshayeli imali enhle. Yingakho kubaluleke kakhulu ukwazi zonke izinto ezicashile ekusebenzeni kwe-air conditioner.
Synthetic kanye amaminerali - sinquma ngesisekelo
Kunamaqembu amabili amafutha we-air conditioning systems - ama-synthetic and mineral compounds. Akunzima kangako ukunquma ukuthi iyiphi ethelwa ku-air conditioner yemoto yakho, kodwa leli bhizinisi lidinga ubuqili obuthile. Zonke izimoto ezakhiqizwa ngaphambi kuka-1994 zigijima ku-R-12 freon. Lolu hlobo lwe-freon luxutshwe namafutha amaminerali e-Suniso 5G.
Izimoto ezikhiqizwe ngemuva kuka-1994 zisebenza kuphela ku-R-134a freon, esetshenziswa ngokuhambisana nama-synthetic compounds PAG 46, PAG 100, PAG 150. Lezi zinhlobo zibizwa nangokuthi i-polyalkyl glycol. I-R-134a brand uwoyela we-freon ayikwazi ukuba yi-mineral, i-synthetic kuphela. Eqinisweni, kunezimo ezingavamile lapho ngo-1994 izimoto zakhiqizwa ngama-compressor lapho kungasetshenziswa kokubili i-R-12 ne-R-134a freon.
Kodwa kufanele ukhumbule ukuthi ngisho noma imoto yakho yawela kulesi sikhathi soguquko, akufanele ugcwalise amaminerali emva kokwakhiwa kwe-polyalkyl glycol - ngale ndlela i-air conditioner yemoto yakho ngeke ihlale isikhathi eside. I-Industrial air conditioning systems (amayunithi esiqandisi) asebenza ku-R-404a freon futhi asebenzisa uwoyela wokwenziwa wesiqandisi we-POE, osesimweni sawo esifana kakhulu namafutha eqembu le-PAG.
Lezi zinhlobo zamafutha akufanele neze zixutshwe zodwa noma zishintshwe ngomunye.
Ngenxa yezici zayo zokuklama, uhlobo lwezimboni lwe-compressor ye-air conditioner aluklanyelwe ukulungiswa okunjalo futhi lungase lwehluleke. Uhlobo lwe-PAG lune-drawback eyodwa - lugcwala ngokushesha umswakama emoyeni ovulekile., ngakho-ke ikhiqizwa emathinini amancane, anganele ngaso sonke isikhathi ukugcwalisa i-refueling eyodwa ye-air conditioner.
Izigaba zemoto - ukusikisela kumshayeli
Imvelaphi yemoto izosiza futhi ekunqumeni ukuthi yimaphi amafutha okufanele athululwe ku-air conditioner yakho. Ngakho-ke, emakethe yezimoto zaseKorea naseJapane, i-PAG 46, i-PAG 100 isetshenziswa emakethe yezimoto yaseMelika, ikakhulukazi i-PAG 150, yezimoto zaseYurophu, uhlobo oluvame kakhulu yi-PAG 46.
Uma unquma ukushintsha uwoyela, kodwa awukwazi umthamo wesistimu, kulokhu kutuswa ukuhlanza ngokuphelele injini ye-compressor ye-air conditioning yemoto. Lezi zinyathelo ziyadingeka ukuze wenze isiqiniseko sokuthi akukho ukungcola okusemishinini nokuthi isistimu yakho ayinawo umoya. Kulapho kuphela lapho ungakwazi ukwengeza inani lamafutha owadingayo. Ngaphambi kokugcwalisa i-refueling, kunconywa ukuthi ugcwalise uhlelo ngengxenye yenani eliphelele lamafutha ukuze ugweme ukushaqeka kwamafutha ku-compressor.
Wonke amabanga anama-coefficients e-viscosity ahlukene, futhi amakhenikha amaningi e-auto atusa ukukhulisa le coefficient ngenxa yezinguquko zesimo sezulu unyaka wonke, njengoba lokhu kunciphisa i-viscosity. Kungakho abantu abaningi basebenzisa uhlobo lukawoyela we-PAG 100 - esimweni sezulu sethu, ukwakheka kune-coefficient ye-viscosity efanelekile.
Noma yini abakutshela yona ezitolo nasezinkonzweni, khumbula ukuthi uwoyela wesiqandisi wendawo yonke awekho emvelweni. Ukuze uthole i-compressor ye-air conditioner yemoto yakho, kufanele usebenzise kuphela uhlobo olunconywayo lwamafutha, olubekwe encwadini yakho yesevisi. Futhi uma kwenzeka ukungasebenzi kahle kwe-air conditioner, kufanele nakanjani uxhumane nochwepheshe.
