Isakhiwo, isekethe, ukulawula ngogesi, uhlelo lokulawula kanye nomgomo wokusebenza kohlelo lokupholisa umoya wezimoto zikagesi
1. Ukwakheka kwesakhiwo sesistimu yokupholisa umoya yezimoto zikagesi ezintsha ezihlanzekile zamandla
Uhlelo lokupholisa umoya lwezimoto zikagesi ezintsha ezisebenzisa amandla ahlanzekile lufana kakhulu nolwezimoto zikaphethiloli zendabuko, eziqukethe ama-compressor, ama-condenser, ama-evaporator, amafeni okupholisa, ama-blower, ama-expansion valve kanye nezesekeli zamapayipi anomfutho ophezulu nophansi. Umehluko ukuthi izingxenye eziyinhloko zohlelo lokupholisa umoya lwezimoto zikagesi ezintsha ezisebenzisa amandla ahlanzekile zazisebenza - i-compressor ayinawo umthombo wamandla wemoto kaphethiloli yendabuko, ngakho-ke ingaqhutshwa kuphela yibhethri lamandla lemoto kagesi uqobo, okudinga ukwengezwa kwemoto yokushayela ku-compressor, inhlanganisela yemoto yokushayela kanye ne-compressor kanye nesilawuli, okungukuthi, sivame ukusho - i-compressor yokuhambisa kagesi.
2. Isimiso sokulawula sohlelo olusha lokupholisa umoya wezimoto zikagesi oluhlanzekile
Isilawuli semoto sonke ∨CU siqoqa isignali yokushintsha i-AC ye-air conditioner, isignali yokushintsha ingcindezi ye-air conditioner, isignali yokushisa kwe-evaporator, isignali yesivinini somoya kanye nesignali yokushisa okuzungezile, bese sakha isignali yokulawula ngebhasi le-CAN bese siyidlulisela kumlawuli we-air conditioner. Ngemuva kwalokho isilawuli se-air conditioner silawula ukuvulwa kwesekethe ye-voltage ephezulu ye-air conditioner compressor.
3. Isimiso sokusebenza sohlelo olusha lokupholisa umoya wezimoto zikagesi oluhlanzekile
I-compressor yomoya opholile kagesi entsha ingumthombo wamandla wesistimu yomoya opholile yezimoto zikagesi entsha yamandla amasha, lapha sihlukanisa ukubanda nokushisa komoya opholile wamandla amasha:
(1) Umgomo wokusebenza kwefriji ohlelweni lokupholisa umoya lwezimoto ezintsha zikagesi ezihlanzekile
Uma uhlelo lokupholisa umoya lusebenza, i-compressor yokupholisa umoya kagesi yenza i-refrigerant ijikeleze ngendlela evamile ohlelweni lokupholisa, i-compressor yokupholisa umoya kagesi icindezela njalo i-refrigerant futhi idlulisele i-refrigerant ebhokisini lokupholisa, i-refrigerant imunca ukushisa ebhokisini lokupholisa umoya bese inwebeka, ukuze ibhokisi lokupholisa umoya liphole, ukuze umoya ovunguzwa yi-blower ube ngumoya obandayo.
(2) Umgomo wokushisa wohlelo lokupholisa umoya lwezimoto zikagesi ezintsha ezisebenzisa amandla ahlanzekile
Ukushisa komoya opholile kwemoto kaphethiloli yendabuko kuncike ku-coolant yokushisa okuphezulu enjinini, ngemva kokuvula umoya ofudumele, i-coolant yokushisa okuphezulu enjinini izogeleza ethangini lomoya ofudumele, futhi umoya ovela ku-blower uzodlula nasethangini lomoya ofudumele, ukuze indawo yomoya yomoya opholile ikwazi ukuphefumula umoya ofudumele, kodwa i-air conditioner yemoto kagesi ngoba ayikho injini, Njengamanje, izimoto eziningi zamandla emakethe zithola ukushisa kwezimoto ezintsha zamandla ngepompo yokushisa noma i-PTC heating.
(3) Isimiso sokusebenza sephampu yokushisa simi kanje: kule nqubo engenhla, uketshezi olubila kancane (njenge-freon ku-air conditioner) luyahwamuka ngemva kokuncishiswa yi-throttle valve, lumunce ukushisa okuvela ekushiseni okuphansi (njengangaphandle kwemoto), bese lucindezela umusi nge-compressor, lwenze izinga lokushisa likhuphuke, lukhiphe ukushisa okumuncwayo nge-condenser bese luncibilika, bese lubuyela ku-throttle. Lo mjikelezo uqhubeka nokudlulisa ukushisa kusuka endaweni epholile kuya endaweni efudumele (edingekayo ekushiseni). Ubuchwepheshe bephampu yokushisa bungasebenzisa i-joule eyodwa yamandla futhi buhambise amandla angaphezu kwe-joule eyodwa (noma ngisho nama-joule amabili) kusuka ezindaweni ezibandayo, okuholela ekongeni okukhulu ekusetshenzisweni kwamandla.
(4) I-PTC isifinyezo se-Positive Temperature Coefficient (i-positive temperature coefficient), ngokuvamile ebhekisela ezintweni ze-semiconductor noma izingxenye ezine-coefficient enkulu ye-positive temperature. Ngokushaja i-thermistor, ukumelana kuyashisa ukuze kukhushulwe izinga lokushisa. I-PTC, esimweni esibi kakhulu, ingafinyelela ukuguqulwa kwamandla okungu-100% kuphela. Kuthatha i-joule eyodwa yamandla ukukhiqiza okungenani i-joule eyodwa yokushisa. Insimbi kagesi kanye ne-curling iron esetshenziswa ekuphileni kwethu kwansuku zonke konke kusekelwe kulesi simiso. Kodwa-ke, inkinga enkulu yokushisa kwe-PTC ukusetshenziswa kwamandla, okuthinta ibanga lokushayela kwezimoto zikagesi. Uma sithatha i-2KW PTC njengesibonelo, ukusebenza ngamandla aphelele ihora kudla ama-2kWh kagesi. Uma imoto ihamba amakhilomitha ayi-100 futhi idla ama-15kWh, ama-2kWh azolahlekelwa amakhilomitha ayi-13 ebanga lokushayela. Abanikazi bezimoto abaningi basenyakatho bakhononda ngokuthi ibanga lezimoto zikagesi linciphile kakhulu, ngokwengxenye ngenxa yokusetshenziswa kwamandla kokushisa kwe-PTC. Ngaphezu kwalokho, esimweni sezulu esibandayo ebusika, umsebenzi wezinto ezibonakalayo ebhethrini lamandla uyancipha, ukusebenza kahle kokukhipha akuphezulu, futhi ibanga lokunyakaza lizoncishiswa.
Umehluko phakathi kokushisa kwe-PTC kanye nokushisa kwephampu yokushisa ye-air conditioning yemoto entsha yamandla ukuthi: Ukushisa kwe-PTC = ukushisa kokukhiqiza, ukushisa kwephampu yokushisa = ukuphatha ukushisa.
