Ukutshintshwa kobushushu ngolwelo njengento ephakathi, kuyimfuneko ukuseka unxibelelwano lokufudumeza ubushushu phakathi kwemodyuli kunye ne-liquid medium, njengebhatyi yamanzi, ukuqhuba ukufudumala okungathanga ngqo kunye nokupholisa ngendlela ye-convection kunye ne-heat conduction.Indawo yokudlulisa ubushushu ingaba ngamanzi, i-ethylene glycol okanye iRefrigerant.Kukwakho nokugqithiswa kobushushu ngokuthe ngqo ngokuntywiliselwa isiqwenga sepali kulwelo lwe-dielectric, kodwa amanyathelo okugquma kufuneka athatyathwe ukuphepha isekethe emfutshane.(Isifudumezi esiPholisayo se-PTC)
Ukupholisa ulwelo olungenakwenziwa ngokuqhelekileyo kusetyenziswa utshintshiselwano lobushushu lolwelo olujikeleze ulwelo kwaye emva koko lazise amakoko kwibhetri kutshintshiselwano lobushushu lwesibini, ngelixa ukupholisa okusebenzayo kusebenzisa i-injini yokupholisa ulwelo oluphakathi kwezitshintshi zobushushu, okanye ukufudumeza kombane/ukufudumeza kwe-oyile ukuphumeza ukupholisa okuphambili.Ukufudumeza, ukupholisa okuphambili kunye nekhabhinethi yabahambi yomoya/imeko yomoya efrijini-ulwelo oluphakathi.
Kwiinkqubo zolawulo lwe-thermal ezisebenzisa umoya kunye nolwelo njengento ephakathi, isakhiwo sikhulu kakhulu kwaye sinzima ngenxa yesidingo sabalandeli, iimpompo zamanzi, ii-heaters, izifudumezi, iipayipi kunye nezinye izixhobo, kwaye ikwasebenzisa amandla ebhetri kwaye inciphisa amandla ebhetri. .ukuxinana kunye nokuxinana kwamandla.Isifudumezi-moya se-PTC)
Inkqubo yokupholisa ibhetri yamanzi epholileyo isebenzisa i-coolant (50% yamanzi / i-50% ethylene glycol) ukuhambisa ukushisa kwebhetri kwi-air-conditioning system yefriji ngokusebenzisa i-battery epholileyo, kwaye emva koko kwimo engqongileyo ngokusebenzisa i-condenser.Ukushisa kwamanzi okungena kwebhetri kupholile ngebhetri Kulula ukufikelela kwiqondo lokushisa eliphantsi emva kokutshintshiselwa kobushushu, kwaye ibhetri inokutshintshwa ukuze iqhube kwinqanaba eliphezulu lobushushu bokusebenza;umgaqo wenkqubo uboniswe kumzobo.Izinto eziphambili zenkqubo yefriji ziquka: i-condenser, i-compressor yombane, i-evaporator, i-valve yokwandisa kunye ne-valve yokuvala, i-cooler yebhethri (i-valve yokwandisa kunye ne-valve yokuvala) kunye nemibhobho yomoya, njl.Umjikelo wamanzi okupholisa uquka:impompo yamanzi yombane, ibhetri (kubandakanywa neepleyiti zokupholisa), ii-coolers zebhetri, iipayipi zamanzi, iitanki zokwandisa kunye nezinye izixhobo.
Kwiminyaka yakutshanje, iinkqubo zolawulo lwe-thermal yebhetri epholileyo ngezinto zokutshintsha kwesigaba (PCM) zivele phesheya nasekhaya, zibonisa amathemba amahle.Umgaqo wokusebenzisa i-PCM yokupholisa ibhetri kukuba: xa ibhetri ikhutshwe ngokukhoyo okukhulu, i-PCM ithatha ukushisa okukhutshwe yibhetri, kwaye iguqukela kwinguqu yesigaba ngokwayo, ukwenzela ukuba ukushisa kwebhetri kwehla ngokukhawuleza.
Kule nkqubo, inkqubo igcina ukushisa kwi-PCM ngendlela yokutshintsha ubushushu besigaba.Xa ibhetri ihlawuliswa, ngakumbi kwimozulu ebanda (oko kukuthi, ukushisa kwe-atmospheric kuphantsi kakhulu kunokushisa kwe-PCT yenguqu yesigaba), i-PCM ikhupha ukushisa kwindalo.
Ukusetyenziswa kwezinto zokutshintsha isigaba kwiinkqubo zolawulo lwe-thermal yebhetri kuneenzuzo zokungadingi iindawo ezihambayo kunye nokusebenzisa amandla ongezelelweyo kwibhetri.Izixhobo zokutshintsha isigaba kunye nenqanaba eliphezulu lokutshintsha ubushushu obufihliweyo kunye ne-thermal conductivity, esetyenziswa kwinkqubo yolawulo lwe-thermal yepakethi yebhetri inokufunxa ngokufanelekileyo ubushushu obukhutshwe ngexesha lokutshaja kunye nokukhupha, ukunciphisa ukunyuka kobushushu bebhetri, kunye nokuqinisekisa ukuba ibhetri isebenza kwi ubushushu obuqhelekileyo.Iyakwazi ukugcina ukusebenza kwebhetri kuzinzile ngaphambi nangemva komjikelezo ophezulu wangoku.Ukongeza izinto ezinomgangatho ophezulu we-thermal conductivity kwiparafini ukwenza i-PCM edibeneyo inceda ukuphucula ukusebenza ngokubanzi kwezinto.
Ukusuka kwimbono yezi ntlobo zintathu zingentla zeefom zolawulo lwe-thermal, ukutshintshwa kwesigaba sokugcinwa kokushisa ukulawulwa kwe-thermal kuneenzuzo ezizodwa, kwaye kufanelekile uphando olongezelelweyo kunye nophuhliso lwamashishini kunye nokusetyenziswa.
Ukongeza, ukusuka kwindawo yokujonga amakhonkco amabini oyilo lwebhetri kunye nophuhliso lwenkqubo yolawulo lobushushu, ezi zimbini kufuneka zidityaniswe ngokwendalo ukusuka kubude obucwangcisiweyo kwaye ziphuhliswe ngokuhambelanayo, ukuze ibhetri ikwazi ukuziqhelanisa ngcono nesicelo kunye nophuhliso lwalo lonke. isithuthi, esinokugcina iindleko zemoto yonke , kwaye inokunciphisa ubunzima besicelo kunye neendleko zophuhliso, kwaye yenze isicelo seqonga, ngaloo ndlela inciphisa umjikelo wophuhliso lwezithuthi zamandla amatsha kunye nokukhawulezisa inkqubela yokuthengisa izithuthi zamandla amatsha ahlukeneyo.
