Nheyo yekushanda kwemhepo inotonhorera yemhepo inotonhorera yemhepo yemotokari
Nheyo yekushanda kwemhepo inotonhodza inotonhodza ine simba remhepo inosanganisira maitiro mana ekutanga: maitiro ekumanikidza, maitiro ekunyorovesa, maitiro ekuwedzera uye maitiro emvura inobuda.
Maitiro ekumanikidza: Compressor inofema firiji ine gasi rakadzikira uye rine pressure shoma parutivi rwe evaporator, yoidzvanya mufiriji ine pressure yakakwirira uye ine pressure yakawanda, yozoitumira ku condenser kuti itonhore. Maitiro aya anowedzera tembiricha uye pressure ye refrigerant.
Maitiro ekunyorovesa: firiji ine gasi rinopisa zvakanyanya uye rinomanikidzwa zvakanyanya rinobviswa nefeni nemhepo inogadzirwa nemota iri mucondenser, uye rinoitwa refrigerant yemvura pakupisa kuri pakati nepakati uye kumanikidzwa kwakanyanya. Basa recondenser nderekuendesa kupisa kwerefrigerant kune nharaunda yekunze kuti itonhore.
Maitiro ekuwedzera: Kana refrigerant yemvura inopfuura nepavharuvhu yekuwedzera kana chubhu yethrottle, kumanikidzwa netembiricha zvinodzikira zvakanyanya uye zvinova tembiricha yakaderera uye utsi hwakanyorova hune simba shoma. Maitiro aya anoita kuti chikamu cherefrigerant chiparare, zvichiita musanganiswa wegasi-mvura wakagadzirira kupinza kupisa.
Maitiro ekubvisa mvura: musanganiswa wegesi nemvura we refrigerant unopinda mu evaporator, unotora kupisa kuri mungoro, uye unobuda mu refrigerant ine tembiricha yakaderera uye ine pressure yakaderera. Evaporator i heat exchanger inoshanda zvakanaka, inobvisa kupisa kunotorwa ne refrigerant mu evaporation kubva mungoro kuburikidza nepombi yemukati, kuitira kuti iwane mhedzisiro yekutonhodza.
Zvikamu zvemuchina wekutonhodza mweya wemota zvinosanganisira compressor, condenser, expansion valve (kana throttle tube), evaporator nezvimwe zvinhu zvinoenderana nazvo. Pamwe chete, zvikamu izvi zvinoumba closed circulation system umo refrigerant inoyerera nguva dzose, ichipedzisa shanduko kubva kugasi kuenda kumvura kuenda kugasi.
Maitiro ekushandisa sisitimu yekutonhodza mhepo yemotokari inomanikidzwa nemhepo ine simba inonyanya kushandiswa mumota. Kuburikidza nesystem iyi, mhepo inotonhodza inogona kuderedza tembiricha mungoro uye kupa nzvimbo yekutyaira yakasununguka.
Sisitimu yekutonhodza mhepo inotonhodza mota ine steam compression chishandiso chinoshandisa refrigerant kutenderera musystem kuti ishandise kupisa, chinonyanya kushandiswa kuderedza tembiricha mumota. Sisitimu iyi ine zvikamu zvinotevera: compressor, condenser, expansion valve, evaporator nemapombi nemavharuvhu anobatanidza zvikamu izvi.
Musimboti wekushanda
Maitiro ekumanikidza: Compressor inofema firiji ine gasi rinodziya uye rinodziya zvishoma mu evaporator, yoidzvanya mufiriji ine gasi rinodziya zvakanyanya uye rinodziya zvakanyanya, yozoitumira ku condenser kuti itonhore.
Maitiro ekudzikamisa: kupisa kwakanyanya uye kumanikidzwa kwakanyanya kwegasi mukondensivha kuenda kunzvimbo inotonhorera (kazhinji mhepo kana mvura) kuti ibudise kupisa, ichidzikamisa kuita mukondensivha wemvura.
Maitiro ekuwedzera: Kana chitofu chemvura chikapfuura nepavharuvhu yekuwedzera, kumanikidzwa nekupisa zvinodzikira uye zvinova utsi hwakanyorova uye hushoma.
Maitiro ekubuda kwemhepo: utsi hwakanyorova hunopinda mu evaporator nekupisa kwakaderera, hunotora kupisa kuri mumota, hunobuda mufiriji ine gasi, uye hunofemerwa zvakare necompressor kuti ipedzise kutenderera kwefiriji.
firiji
Chinhu chinowanzo shandiswa mufiriji ndiR-134a (tetrafluoroethane), iyo inonwisa kupisa kwakawanda kana ichishandurwa kubva mumvura kuita gasi mu evaporator, zvichikonzera kutonhora.
Nhoroondo yekare uye kukura kwetekinoroji
Nheyo huru yesystem yekutonhodza mhepo yemotokari yakafanana neyemuchina wekutonhodza mhepo yemumba, iyo inoshandisa shanduko yemamiriro emuchina wekutonhodza kuti itonhodze. Nekuvandudzwa kwetekinoroji, masisitimu emazuva ano ekutonhodza mhepo yemotokari anewo masensa akasiyana-siyana uye masisitimu ekudzora kuti awane kudzora tembiricha kwakanyatsojeka uye kushandiswa kwesimba zvine hungwaru.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa zvikamu zvemotokari zveMG&750 zvinogamuchirwa Kutenga.
