Iyini inzwa ye-automobile air conditioning pressure
Inzwa yengcindezi ye-automotive air conditioning iyingxenye eyinhloko yesistimu yesiqandisi. Umsebenzi wayo oyinhloko ukuqapha ukucindezela kwesiqandisi epayipini le-air conditioning ngesikhathi sangempela, ukuqinisekisa ukusebenza okuphephile kwe-compressor, nokusebenza nezinye izingxenye ukulawula ngokunembile ukuqala nokumiswa kwefeni yokupholisa kanye ne-compressor. Ivamise ukufakwa epayipini lomfutho ophezulu we-air conditioning endaweni yenjini futhi idlulisele idatha yengcindezi eqoqiwe ku-ECU yenjini noma iyunithi yokulawula isimo somoya esikhethekile. Lapho i-ECU ithola isignali yokucindezela evamile, iqala i-compressor kanye ne-cooling fan; Uma kutholwa isignali yokucindezela okungavamile, izinyathelo ezisheshayo zithathwa ukuze kuvinjelwe imishini yokupholisa umoya njengama-compressor kusukela ekuqaleni, ngaleyo ndlela kuvikelwe lonke uhlelo lwesiqandisi. .
Inzwa yokucindezela kwe-air conditioning ngokuvamile isebenzisa ukwakheka kwesistimu yezintambo ezintathu, imodi yayo yokulawula ihlanganisa isignali ye-analog, ibhasi ye-Lin kanye nokulawula umjikelezo wemisebenzi izinhlobo ezintathu. Ukuze ulinganise inzwa yokucindezela ye-air conditioner, sebenzisa i-multimeter ukuze ulinganise ikhebuli yamandla, ikhebuli yaphansi, nekhebuli yesiginali yenzwa. Ezimweni ezivamile, ikhebuli yamandla ingu-5V noma 12V, ikhebuli yaphansi ingu-0V, futhi ikhebula lesignali lishintshashintsha kububanzi obungu-0.5V ukuya ku-4.5V noma u-1V ukuya ku-5V. Uma inani elilinganisiwe lihluke kakhulu kunani elijwayelekile, kungase kusho ukuthi inzwa ilimele noma kukhona ukuxhumana okubonakalayo kumahhanisi.
Inzwa yokucindezela kwe-air conditioning idlala indima ebalulekile ohlelweni lwesiqandisi sezimoto. Uma inzwa ihluleka, ingase iholele ekubeni kungabikho umphumela wokupholisa emotweni, i-compressor ayikwazi ukusebenza, noma ukuqala njalo nokumisa izinkinga. Ngakho-ke, ukuhlolwa okuvamile nokugcinwa kwenzwa yokucindezela umoya kuyisinyathelo esibalulekile sokuqinisekisa ukusebenza okuvamile kwesistimu ye-air conditioning yemoto.
Isimiso sokusebenza senzwa yengcindezi ye-automotive air conditioning sisekelwe esilinganisweni sokucindezela, ngokuvamile okuhlanganisa ifilimu elincanyana kanye negridi yezihlungi. Lapho ingcindezi ohlelweni lwe-automotive air conditioning lushintsha, ingcindezi yendawo elinganisiwe izodluliselwa kufilimu esenzwa. Ifilimu ikhubaza ngaphansi kwesenzo sokucindezela, okuholela ekushintsheni kokumelana okuhambisanayo kwegridi yokumelana kufilimu. Lolu shintsho lokumelana lungatholwa futhi lufundwe yisekethe exhunywe kudeshibhodi noma enye iyunithi yokulawula. .
Ukusetshenziswa kwezinzwa zengcindezi ye-automotive air conditioning kuma-automotive air conditioning systems kuhlanganisa izinhlobo eziningi, uhlobo ngalunye lunomsebenzi walo othize kanye nendawo yokufaka. Isibonelo, umshini wokushintsha amandla kagesi aphezulu ufakwa epayipini le-condenser inlet ukuze kulungiswe isivinini senjini yesiphephetha-moya futhi kuqinisekiswe ukuthi umfutho we-condenser ugcinwa endaweni ephephile. Lapho ingcindezi yokujiya ingaphansi kuka-1.51 mpa, ifeni igcina ukusebenza kwejubane eliphansi. Uma ingcindezi isingaphezu kuka-1.5 mpa, isiphephetha-moya siyasheshisa siye esivinini esikhulu. Ngaphezu kwalokho, inkinobho yokushisa ephindwe kabili itholakala eduze kwe-condenser futhi ihlanganisa ukushintshwa komfutho ophezulu kanye nezinga lokushisa elipholile lenjini ukulawula ukusebenza kwe-condensing fan motor. Lapho izinga lokushisa elipholile liphakathi kuka-95 no-102 ° C, ifeni iphenduka ngesivinini esiphansi; Lapho izinga lokushisa lidlula i-102 ° C, ifeni isebenza ngesivinini esikhulu.
Indima yenzwa yengcindezi ye-automotive air conditioning in automotive air conditioning system ukuvikela uhlelo kanye nokwenza ngcono ukusebenza kahle. Zivimbela ukucindezela okukhulu ekubangeleni umonakalo ezingxenyeni ngokuqapha izinguquko zengcindezi ngaphakathi kwesistimu. Isibonelo, uma ingcindezi yomugqa wengcindezi ephezulu ingaphansi kuka-0.2 mpa noma ngaphezulu kuka-3.2 mpa, i-compressor's electromagnetic clutch iyanqanyulwa ukuze kuvikelwe uhlelo; I-clutch ihlala isebenza phakathi kuka-0.22 no-3.2 mpa. Ngaphezu kwalokho, ukushintsha kwezinga lokushisa kwangaphandle kunqamula i-compressor electromagnetic clutch lapho izinga lokushisa lingaphansi kuka-5 ° C, livimbela isiminyanzeli se-air conditioning ekusebenzeni emazingeni okushisa aphansi.
