Ehlobo elishisayo noma ebusika obubandayo, umoya opholile emotweni ubalulekile kithina bathandi bezimoto, ikakhulukazi lapho amafasitela egcwala inkungu noma eqhwa. Amandla ohlelo lomoya opholile lokucisha umoya ngokushesha nokuncibilikisa iqhwa adlala indima ebalulekile ekuphepheni kokushayela. Ezimotweni zikagesi, ezingenayo injini kaphethiloli, azinawo umthombo wokushisa wokushisa, futhi i-compressor ayinawo amandla okushayela enjini okupholisa. Ngakho-ke izimoto zikagesi ezihlanzekile zinikeza kanjani imisebenzi yokupholisa umoya opholile kanye nokushisa? Ake sithole.
01 Izingxenye Zohlelo Lokupholisa Lomoya Opholile
Izingxenye zesistimu yokupholisa umoya zifaka: i-compressor kagesi, i-condenser, i-pressure sensor, i-electronic expansion valve, i-evaporator, amapayipi aqinile okupholisa umoya, amapayipi, kanye nesekethe yokulawula.
I-compressor:
Ithatha i-refrigerant yegesi enokushisa okuphansi kanye nokucindezela okuphansi bese iyicindezela ibe yigesi ewuketshezi enokushisa okuphezulu kanye nokucindezela okuphezulu. Ngesikhathi sokucindezela, isimo se-refrigerant asishintshi, kodwa izinga lokushisa kanye nokucindezela kuyaqhubeka nokukhula, kwakha igesi eshisayo kakhulu.
I-Condenser:
I-condenser isebenzisa ifeni yokupholisa ezinikele ukusabalalisa ukushisa kwe-refrigerant yokushisa okuphezulu kanye nokucindezela okuphezulu emoyeni ozungezile, ipholise i-refrigerant. Kule nqubo, i-refrigerant iyashintsha isuka esimweni segesi iye esimweni soketshezi, futhi isesimweni sokushisa okuphezulu kanye nokucindezela okuphezulu.
I-Valve Yokunweba:
Isiqandisi soketshezi esinokushisa okuphezulu kanye nokucindezela okuphezulu sidlula ngevalvu yokunweba ukuze sinciphise ingcindezi ngaphambi kokungena ku-evaporator. Inhloso yale nqubo ukupholisa nokunciphisa ingcindezi yesiqandisi nokulawula ukugeleza ukuze kulawulwe amandla okupholisa. Lapho isiqandisi sidlula ngevalvu yokunweba, siyashintsha sisuka ekubeni uketshezi olunokushisa okuphezulu, olunokucindezela okuphezulu siye ekubeni uketshezi olunokushisa okuphansi, olunokucindezela okuphansi.
Isihwamukisi:
I-refrigerant yoketshezi enokushisa okuphansi, enomfutho ophansi evela ku-expansion valve imunca ukushisa okukhulu okuvela emoyeni ozungezile ku-evaporator. Phakathi nale nqubo, i-refrigerant ishintsha isuka ekubeni uketshezi iye ekubeni igesi enokushisa okuphansi, enomfutho ophansi. Le gesi ibe isimuncwa yi-compressor ukuze iphinde icindezelwe.
Ngokombono womgomo wokupholisa, uhlelo lokupholisa umoya lwezimoto zikagesi lufana kakhulu nolwezimoto zendabuko ezisebenzisa uphethiloli. Umehluko ulele kakhulu endleleni yokushayela ye-compressor yokupholisa umoya. Ezimotweni zendabuko ezisebenzisa uphethiloli, i-compressor iqhutshwa yi-pulley yebhande lenjini, kanti ezimotweni zikagesi, i-compressor ilawulwa ngokulawula kwe-elekthronikhi ukushayela imoto, okuyiyo eqhuba i-compressor nge-crankshaft.
02 Uhlelo Lokushisa Lomoya Opholile
Umthombo wokushisa utholakala kakhulu ngokushisa kwe-PTC (Positive Temperature Coefficient). Izimoto zikagesi ezihlanzekile ngokuvamile zinezinhlobo ezimbili: i-PTC module yokushisa umoya kanye ne-PTC module yokushisa amanzi. I-PTC uhlobo lwe-semiconductor thermistor, futhi isici sayo ukuthi ukumelana kwezinto ze-PTC kuyanda njengoba izinga lokushisa likhuphuka. Ngaphansi kwe-voltage engaguquki, i-PTC heater ishisa ngokushesha emazingeni okushisa aphansi, futhi njengoba izinga lokushisa likhuphuka, ukumelana kuyanda, ugesi uyancipha, futhi amandla asetshenziswa yi-PTC ayancipha, ngaleyo ndlela kugcinwa izinga lokushisa elingaguquki.
Isakhiwo Sangaphakathi Se-Air Heating PTC Module:
Yakhiwe isilawuli (kufaka phakathi imoduli yokushayela ye-voltage ephansi/ephezulu), izixhumi ze-wire harness ezinomfutho ophezulu/ophansi, ifilimu yokumelana nokushisa ye-PTC, i-silicone pad evikela ukushisa, kanye negobolondo langaphandle, njengoba kuboniswe esithombeni.
Imojuli ye-PTC yokushisa umoya ibhekisela ekufakweni ngqo kwe-PTC enkabeni yesistimu yomoya ofudumele yekhabhini. Umoya wekhabhini ujikeleziswa yi-blower bese ufudunyezwa ngqo yi-heater ye-PTC. Ifilimu yokumelana nokushisa ngaphakathi kwemojuli ye-PTC yokushisa umoya inikwe amandla yi-voltage ephezulu futhi ilawulwa yi-VCU (Iyunithi Yokulawula Izimoto).
03 Ukulawulwa Kwesistimu Yomoya Opholile Yezimoto Zikagesi
I-VCU yemoto kagesi iqoqa izimpawu ezivela kuswishi ye-A/C, swishi yokucindezela kwe-A/C, izinga lokushisa le-evaporator, isivinini sefeni, kanye nezinga lokushisa elizungezile. Ngemva kokucubungula nokubala, ikhiqiza izimpawu zokulawula, ezidluliselwa kumlawuli womoya opholile ngebhasi le-CAN. Isilawuli somoya opholile silawula ukuvulwa/ukuvalwa kwesekethe ye-high-voltage ye-compressor yomoya opholile, njengoba kuboniswe esithombeni.
Lokho kuphetha isingeniso esijwayelekile ohlelweni lokupholisa umoya lwezimoto zikagesi. Ingabe ukuthole kuwusizo? Landela i-Yiyi New Energy Vehicles ukuze uthole ulwazi olwengeziwe lobuchwepheshe olwabelwana ngalo njalo ngeviki.
