Isakhiwo, isekethe, isilawuli se-elekthronikhi, uhlelo lokulawula kanye nesimiso sokusebenza sesistimu ye-air conditioning yemoto kagesi
1. Ukubunjwa kwesakhiwo sesistimu ye-air conditioning yamandla amasha wezimoto ezihlanzekile zikagesi
Isistimu yokupholisa umoya yezimoto zikagesi ezihlanzekile zamandla amasha ngokuyisisekelo iyafana naleyo yezimoto zikaphethiloli zendabuko, ezihlanganisa ama-compressor, ama-condensers, ama-evaporator, amafeni okupholisa, ama-blower, ama-valve okunweba kanye nezinsiza zamapayipi ezinomfutho ophansi nophansi. Umehluko ukuthi izingxenye eziyinhloko zohlelo olusha lwe-air conditioning yemoto kagesi olusetshenziswa ukusebenza - i-compressor ayinawo umthombo wamandla wemoto kaphethiloli yendabuko, ngakho-ke ingashayelwa kuphela ibhethri lamandla emoto kagesi uqobo. , okudinga ukwengezwa kwemoto yokushayela ku-compressor, inhlanganisela ye-drive motor kanye ne-compressor kanye nesilawuli, okungukuthi, sivame ukusho - i-electric scroll compressor
2. Umgomo wokulawula wohlelo olusha lwe-air conditioning yemoto kagesi
Sonke isilawuli semoto ∨CU siqoqa isignali yokushintshwa kwe-AC yesimo somoya, isignali yokushintshwa kwengcindezi ye-air conditioner, isignali yezinga lokushisa evaporator, isignali yesivinini somoya kanye nesignali yezinga lokushisa elizungezile, bese yenza isignali yokulawula ngebhasi le-CAN futhi iyidlulisele emoyeni. isilawuli se-conditioner. Khona-ke isilawuli se-air conditioner silawula ukuphuma kwesekethe ye-voltage ephezulu ye-compressor ye-air conditioner.
3. Isimiso sokusebenza sohlelo olusha lwe-air conditioning yemoto kagesi
I-compressor yomoya omusha wamandla kagesi ingumthombo wamandla wohlelo olusha lwe-air conditioning yemoto kagesi, lapha sihlukanisa isiqandisi nokushisisa kwesimo somoya samandla amasha:
(1) Umgomo wokusebenza kwesiqandisi wesistimu yokupholisa umoya yezimoto zikagesi ezihlanzekile zamandla amasha
Lapho uhlelo lwe-air conditioning lusebenza, i-compressor ye-air conditioning kagesi yenza isiqandisi sijikeleze ngendlela evamile ohlelweni lwesiqandisi, i-compressor ye-air conditioning kagesi icindezela ngokuqhubekayo isiqandisi futhi idlulisele isiqandisi ebhokisini lokuhwamuka, isiqandisi sibamba ukushisa ebhokisini lokuhwamuka futhi sandise. , ukuze ibhokisi lomhwamuko lipholiswe, ukuze umoya ovunguzayo ube umoya obandayo.
(2) Umgomo wokushisisa wesistimu ye-air conditioning yezimoto ezintsha zikagesi ezihlanzekile
I-air-conditioning yemoto kaphethiloli yendabuko incike ekupholiseni izinga lokushisa eliphezulu enjinini, ngemva kokuvula umoya ofudumele, isipholile esiphezulu esisenjinini sizogeleza ethangini lomoya ofudumele, nomoya ophuma ku- blower nawo uzodlula. ngokusebenzisa ithangi lomoya elifudumele, ukuze indawo yokuphuma komoya ye-air conditioner ikhiphe umoya ofudumele, kodwa imoto kagesi i-air conditioning ngoba ayikho injini, Okwamanje, izimoto eziningi zamandla amasha emakethe zithola imoto entsha yamandla. Ukushisa ngepompo yokushisa noma ukufudumeza kwe-PTC.
(3) Isimiso sokusebenza sephampu yokushisa simi kanje: kule nqubo engenhla, uketshezi olubilisa kancane (njenge-freon ku-air conditioner) luyahwamuka ngemva kokucindezelwa yi-throttle valve, lumunca ukushisa okusuka ekushiseni okuphansi (okufana nalokhu. njengangaphandle kwemoto), bese icindezela isitimu nge-compressor, yenza izinga lokushisa likhuphuke, ikhiphe ukushisa okumuncwe nge-condenser futhi ifakwe uketshezi, bese ibuyela ku-throttle. Lo mjikelezo udlulisela ngokuqhubekayo ukushisa kusuka endaweni epholile kuya endaweni efudumele (ukushisa okudingekayo). Ubuchwepheshe bephampu yokushisa bungasebenzisa ijoule elingu-1 lamandla futhi buhambise ngaphezu kwe-joule engu-1 (noma ngisho nama-joule angu-2) wamandla ezindaweni ezibandayo, okuholela ekongeni okukhulu ekusetshenzisweni kwamandla.
(4) I-PTC isifinyezo se-Positive Temperature Coefficient (i-coefficient yokushisa ephozithivu), ngokuvamile ebhekisela ezintweni ze-semiconductor noma izingxenye ezine-coefficient enkulu yezinga lokushisa eliphozithivu. Ngokushaja i-thermistor, ukumelana kuyashisa ukuze kukhuphule izinga lokushisa. I-PTC, esimweni esibucayi, ingafinyelela kuphela ukuguqulwa kwamandla angu-100%. Kuthatha ijoule elingu-1 lamandla ukukhiqiza okungenani ijoule elingu-1 lokushisa. Insimbi kagesi kanye nensimbi egoqayo esetshenziswa ekuphileni kwethu kwansuku zonke konke kusekelwe kulesi simiso. Kodwa-ke, inkinga enkulu yokushisa kwe-PTC ukusetshenziswa kwamandla, okuthinta uhla lokushayela kwezimoto zikagesi. Ukuthatha i-2KW PTC njengesibonelo, ukusebenza ngamandla aphelele ihora kudla u-2kWh kagesi. Uma imoto ihamba amakhilomitha angu-100 futhi idla u-15kWh, i-2kWh izolahlekelwa ngamakhilomitha angu-13 okushayela. Abanikazi bezimoto abaningi abasenyakatho bakhala ngokuthi ububanzi bezimoto zikagesi bunciphe kakhulu, ngokwengxenye ngenxa yokusetshenziswa kwamandla okushisa kwe-PTC. Ngaphezu kwalokho, esimweni sezulu esibandayo ebusika, umsebenzi wezinto ezibonakalayo ebhethrini lamandla uyancipha, ukusebenza kahle kokukhishwa akuphezulu, futhi imayela lizokwehliswa.
Umehluko phakathi kokushisisa kwe-PTC kanye nokushisisa kwephampu yokushisa ye-air conditioning yemoto yamandla entsha ukuthi: Ukushisa kwe-PTC = ukushisa kokukhiqiza, ukushisa kwephampu yokushisa = ukuphatha ukushisa.
