1. Iimfuno zoLawulo loBushushu beZithuthi zoMbane (I-HVCH)
Indawo yabakhweli yindawo yokusingqongileyo apho umqhubi ahlala khona ngelixa imoto isebenza. Ukuze kuqinisekiswe ukuba umqhubi uhlala kwindawo yokuqhuba ekhululekileyo, ulawulo lobushushu lwendawo yabakhweli kufuneka lulawule ubushushu, ukufuma, kunye nobushushu bomoya kwindawo yangaphakathi yesithuthi. Iimfuneko zolawulo lobushushu lwendawo yabakhweli phantsi kweemeko ezahlukeneyo ziboniswe kwiTheyibhile 1.
Ulawulo lobushushu bebhetri yamandla luyimfuneko ebalulekileyo ukuqinisekisa ukusebenza kakuhle nangokukhuselekileyo kwezithuthi zombane. Xa ubushushu buphezulu kakhulu, buya kubangela ukuvuza kolwelo kunye nokutsha okuzenzekelayo, okuya kuchaphazela ukhuseleko lokuqhuba; xa ubushushu buphantsi kakhulu, itshaja yebhetri kunye nomthamo wokukhupha uya kuncitshiswa ukuya kwinqanaba elithile. Ngenxa yobuninzi bayo bamandla aphezulu kunye nobunzima obulula, iibhetri ze-lithium ziye zaba ziibhetri zamandla ezisetyenziswa kakhulu kwizithuthi zombane. Iimfuno zolawulo lobushushu beebhetri ze-lithium kunye nomthwalo wobushushu bebhetri phantsi kweemeko ezahlukeneyo eziqikelelwayo ngokweencwadi ziboniswe kwiTheyibhile 2. Ngokunyuka kancinci kobunzima bamandla beebhetri zamandla, ukwanda kobubanzi bobushushu kwindawo yokusebenza, kunye nokwanda kwesantya sokutshaja ngokukhawuleza, ukubaluleka kolawulo lobushushu bebhetri yamandla kwinkqubo yolawulo lobushushu kuye kwabonakala ngakumbi, kungekuphela nje ukuhlangabezana neemeko ezahlukeneyo zendlela kunye neendlela ezahlukeneyo zokutshaja kunye nokukhupha. Umthwalo wolawulo lobushushu uyatshintsha phantsi kweemeko zokusebenza zesithuthi, ukufana kwentsimi yobushushu phakathi kweepakethi zebhetri kunye nokuthintela kunye nokulawula ukubaleka kobushushu kufuneka kuhlangatyezwane nazo zonke iimfuno zolawulo lobushushu phantsi kweemeko ezahlukeneyo zokusingqongileyo ezifana nokubanda kakhulu, ubushushu obuphezulu kunye neendawo ezinomswakama ophezulu, kunye neendawo ezishushu zasehlotyeni nasebusika. imfuneko.
2. Inqanaba lokuqala lokufudumeza i-PTC
Kwinqanaba lokuqala lophuhliso lwezithuthi zombane, iteknoloji ephambili isekelwe ekutshintsheni iibhetri, iimoto kunye nezinye iinkqubo zamandla. Isekelwe kuphuculo oluhamba kancinci kancinci. I-air conditioner yesithuthi sombane esicocekileyo kunye ne-air conditioner yesithuthi sepetroli zombini ziyayiqonda imisebenzi yokufrijisa ngomjikelo wokucinezelwa komphunga. Umahluko phakathi kwezi zimbini kukuba i-air conditioner yesithuthi sepetroli iqhutywa ngokungathanga ngqo yinjini ngebhanti, ngelixa isithuthi sombane esicocekileyo sisebenzisa ngqo i-electric drive compressor ukuqhuba umjikelo wokufrijisa. Xa izithuthi zepetroli zifudunyezwa ebusika, ubushushu obumdaka benjini busetyenziswa ngqo ukufudumeza igumbi labakhweli ngaphandle komthombo wobushushu owongezelelweyo. Nangona kunjalo, ubushushu obumdaka bemoto yezithuthi zombane ezicocekileyo abunakwanelisa iimfuno zokufudumeza ebusika. Ke ngoko, ukufudumeza ebusika yingxaki ekufuneka izithuthi zombane ezicocekileyo ziyisombulule. . I-heater ye-positive temperature coefficient (positive temperature coefficient, PTC) yenziwe yi-PTC ceramic heating element kunye ne-aluminium tube (Isifudumezi sePTC esipholileyo/Isifudumezi somoya se-PTC), enezibonelelo zokuxhathisa ubushushu obuncinci kunye nokusebenza kakuhle kokudlulisa ubushushu, kwaye isetyenziswa kwisiseko somzimba wezithuthi zepetroli. Ke ngoko, izithuthi zombane zakuqala zazisebenzisa ukupholisa umjikelo wokuphola we-vapor compression kunye nokufudumeza kwe-PTC ukuze kufezekiswe ulawulo lobushushu lwegumbi labakhweli.
2.1 Ukusetyenziswa kwetekhnoloji yepompo yobushushu kwinqanaba lesibini
Kwindlela yokusetyenziswa, izithuthi zombane zifuna kakhulu ukusetyenziswa kwamandla okufudumeza ebusika. Ngokwembono ye-thermodynamic, i-COP yokufudumeza ye-PTC isoloko ingaphantsi kwe-1, nto leyo eyenza ukusetyenziswa kwamandla okufudumeza kwe-PTC kuphakame kwaye izinga lokusetyenziswa kwamandla liphantsi, nto leyo ethintela kakhulu i-mileage yezithuthi zombane. Itekhnoloji yepompo yobushushu isebenzisa umjikelo woxinzelelo lomphunga ukusebenzisa ubushushu obuphantsi kwindawo engqongileyo, kwaye i-COP yethiyori ngexesha lokufudumeza ingaphezulu kwe-1. Ke ngoko, ukusebenzisa inkqubo yepompo yobushushu endaweni ye-PTC kunokunyusa uluhlu lokuhamba kwezithuthi zombane phantsi kweemeko zokufudumeza. Ngokuphuculwa ngakumbi kwamandla kunye namandla ebhetri yamandla, umthwalo wobushushu ngexesha lokusebenza kwebhetri yamandla nawo uyanda kancinci kancinci. Isakhiwo sokupholisa umoya wendabuko asinakuhlangabezana neemfuno zolawulo lobushushu bebhetri yamandla. Ke ngoko, ukupholisa ulwelo kuye kwaba yindlela ephambili yolawulo lobushushu bebhetri. Ngaphezu koko, ekubeni ubushushu obukhululekileyo obufunekayo ngumzimba womntu bufana nobushushu apho ibhetri yamandla isebenza khona ngokuqhelekileyo, iimfuno zokupholisa zegumbi labakhweli kunye nebhetri yamandla zinokufezekiswa ngokudibanisa abatshintshi bobushushu ngaxeshanye kwinkqubo yepompo yobushushu yegumbi labakhweli. Ubushushu bebhetri yamandla bususwa ngokungathanga ngqo yi-heat exchanger kunye nokupholisa okwesibini, kwaye inqanaba lokudibanisa kwenkqubo yolawulo lobushushu besithuthi sombane liphuculwe. Nangona inqanaba lokudibanisa liphuculwe, inkqubo yolawulo lobushushu kweli nqanaba idibanisa kuphela ukupholisa kwebhetri kunye nendawo yabakhweli, kwaye ubushushu obulahlekileyo bebhetri kunye nemoto abusetyenziswanga ngokufanelekileyo.
