Iyini inzwa yokucindezela umoya wemoto
Inzwa yokucindezela umoya opholile yezimoto iyisici esiyinhloko sohlelo lokuqandisa. Umsebenzi wayo oyinhloko ukuqapha ingcindezi yesiqandisi epayipini lokupholisa umoya ngesikhathi sangempela, ukuqinisekisa ukusebenza okuphephile kwe-compressor, nokusebenza nezinye izingxenye ukulawula ngokunembile ukuqala nokuma kwefeni yokupholisa kanye ne-compressor. Ngokuvamile ifakwa epayipini lokucindezela umoya opholile engxenyeni yenjini futhi idlulisela idatha yokucindezela eqoqwe ku-ECU yenjini noma iyunithi yokulawula umoya opholile ekhethekile. Lapho i-ECU ithola isignali yokucindezela evamile, iqala i-compressor kanye nefeni yokupholisa; Uma kutholakala isignali yokucindezela okungajwayelekile, kuthathwa izinyathelo ezisheshayo ukuvimbela imishini yokupholisa umoya efana nama-compressor ukuthi iqale, ngaleyo ndlela kuvikelwe lonke uhlelo lokuqandisa.
Inzwa yokucindezela umoya opholile ivame ukusebenzisa ukwakheka kwesistimu yezintambo ezintathu, imodi yayo yokulawula ifaka isignali ye-analog, i-Lin bus kanye nokulawula umjikelezo womsebenzi izinhlobo ezintathu. Ukuze ulinganise inzwa yokucindezela ye-air conditioner, sebenzisa i-multimeter ukukala ikhebula lamandla, ikhebula lomhlabathi, kanye nekhebula lesignali lenzwa. Ezimweni ezivamile, ikhebula lamandla lingu-5V noma u-12V, ikhebula lomhlabathi lingu-0V, kanti ikhebula lesignali liyashintshashintsha kusukela ku-0.5V kuya ku-4.5V noma ku-1V kuya ku-5V. Uma inani elilinganisiwe lihluke kakhulu kunenani elijwayelekile, kungasho ukuthi inzwa yonakele noma kukhona uxhumano olubonakalayo ku-harness.
Inzwa yokucindezela umoya opholile idlala indima ebalulekile ohlelweni lokuqandisa imoto. Uma inzwa yehluleka, ingase ingabi nomthelela wokupholisa emotweni, i-compressor ayikwazi ukusebenza, noma izinkinga zokuqala nokumisa njalo. Ngakho-ke, ukuhlolwa njalo nokugcinwa kwenzwa yokucindezela umoya opholile kuyisinyathelo esibalulekile ukuqinisekisa ukusebenza okuvamile kohlelo lokupholisa umoya wemoto.
Isimiso sokusebenza senzwa yokucindezela umoya wezimoto sisekelwe ekulinganisweni kwengcindezi, ngokuvamile equkethe ifilimu encane kanye negridi yama-resistor. Lapho ingcindezi ohlelweni lokupholisa umoya wezimoto ishintsha, ingcindezi ye-medium elinganisiwe izodluliselwa efilimini esenzwa. Ifilimu iyashintshashintsha ngaphansi kwesenzo sengcindezi, okuholela ekushintsheni kokumelana okuhambisanayo kwegridi yokumelana efilimini. Lolu shintsho lokumelana lungatholakala futhi lufundwe yisekethe exhunywe kudeshibhodi noma kwenye iyunithi yokulawula.
Ukusetshenziswa kwezinzwa zokucindezela umoya wezimoto ezinhlelweni zokupholisa umoya zezimoto kuhlanganisa izinhlobo eziningi, uhlobo ngalunye lunomsebenzi walo othize kanye nendawo yokufakwa. Isibonelo, kufakwa iswishi ephezulu yamandla e-condenser epayipini lokungena le-condenser ukuze kulungiswe ijubane le-fan motor futhi kuqinisekiswe ukuthi ingcindezi ye-condenser igcinwa ngaphakathi kwebanga eliphephile. Lapho ingcindezi yokuncibilikisa ingaphansi kuka-1.51 mpa, ifeni igcina ukusebenza kwesivinini esiphansi. Uma ingcindezi idlula u-1.5 mpa, ifeni ishesha iye esivinini esiphezulu. Ngaphezu kwalokho, iswishi yokushisa ephindwe kabili itholakala eduze kwe-condenser futhi ihlanganisa iswishi yokucindezela ephezulu nezinga lokushisa le-coolant yenjini ukulawula ukusebenza kwe-condensing fan motor. Lapho izinga lokushisa le-coolant liphakathi kuka-95 no-102 ° C, ifeni ijikeleza ngesivinini esiphansi; Lapho izinga lokushisa lidlula u-102 ° C, ifeni isebenza ngesivinini esiphezulu.
Indima yenzwa yokucindezela umoya wezimoto ohlelweni lokupholisa umoya wezimoto ukuvikela uhlelo nokuthuthukisa ukusebenza kahle. Zivimbela ukucindezela okukhulu ekubangeleni umonakalo ezingxenyeni ngokuqapha izinguquko zokucindezela ngaphakathi kohlelo. Isibonelo, lapho ukucindezela komugqa wokucindezela okuphezulu kungaphansi kuka-0.2 mpa noma ngaphezulu kuka-3.2 mpa, i-clutch kagesi ye-compressor iyanqanyulwa ukuvikela uhlelo; I-clutch ihlala isebenza phakathi kuka-0.22 no-3.2 mpa. Ngaphezu kwalokho, inkinobho yokushisa yangaphandle inqamula i-clutch kagesi ye-compressor lapho izinga lokushisa lingaphansi kuka-5 ° C, okuvimbela i-compressor yokupholisa umoya ukuthi isebenze emazingeni okushisa aphansi.
