Multi Energy LiBr Absorption Chiller
Mfundo yogwira ntchito
Pogwiritsa ntchito mpweya wotentha kwambiri komanso gasi wachilengedwe monga gwero la kutentha, mpweya wa flue ndi chiller wa LiBr absorption chiller (The chiller/The unit) umagwiritsa ntchito mavuvu amadzi a refirgerant kupanga madzi ozizira.
M'moyo wathu watsiku ndi tsiku, monga tonse tikudziwira, timakhala oziziritsa ngati tikudontheza mowa pakhungu, ndichifukwa choti nthunziyo imayamwa kutentha pakhungu lathu.Osati mowa wokha, mitundu ina yonse yamadzimadzi imatha kuyamwa kutentha kozungulira pamene mpweya umatulutsa.Ndipo kutsika kwa mphamvu ya mumlengalenga, kumachepetsa kutentha kwa mpweya.Mwachitsanzo, kutentha kwa madzi ndi 100 ℃ pansi pa 1 atmosphere of pressure, koma ngati mpweya wa mumlengalenga utsika kufika pa 0.00891, kutentha kwa madzi kumatentha kufika pa 5℃.Ndichifukwa chake pansi pa vacuum, madzi amatha kusungunuka pakatentha kwambiri.Mfundo imeneyi bwino ntchito ndi bwino mafakitale chiller opanga kupititsa patsogolo dzuwa la mankhwala awo.
Uwu ndiye mfundo yoyambira yogwiritsira ntchito mphamvu zambiri zamayamwidwe a LiBr.Madzi (refrigerant) amaphwera mu chotengera cha vacuum chapamwamba ndikuyamwa kutentha kuchokera m'madzi oti aziziritsidwa.Mpweya wa refrigerant umalowetsedwa ndi yankho la LiBr(absorbent) ndikuzunguliridwa ndi mapampu.Njirayi ikubwereza, kuzungulira komwe kumamveka bwino ndi opanga makina opangira zitsulo.
Kuzizira kuzungulira
Mfundo yogwirira ntchito ya multi-energy LiBr absorption chiller ikuwonetsedwa ngati Chithunzi 2-1.Njira yosungunulira yochokera ku chopopera, yomwe imapopedwa ndi mpope woyankhira, imadutsa kutentha kwapang'onopang'ono (LTHE) ndi kutentha kwapang'onopang'ono (HTHE), kenako imalowa mu jenereta yotentha kwambiri (HTG), komwe imawiritsidwa ndi mpweya wotentha kwambiri ndi mpweya wa naturak kuti apange mpweya wothamanga kwambiri, wotentha kwambiri komanso wozizira kwambiri.Njira yothirira imasandulika kukhala yapakatikati.Njira yovutayi imakongoletsedwa ndi wopanga bwino kwambiri wopanga zoziziritsa kukhosi.
Njira yapakatikati imayenda kudzera pa HTHE kulowa mu jenereta yotsika kutentha (LTG), komwe imatenthedwa ndi nthunzi ya mufiriji kuchokera ku HTG kuti ipange mpweya wozizira.Njira yapakatikati imakhala yankho lokhazikika.
Mpweya wothamanga kwambiri, wotentha kwambiri wa refrigerant wopangidwa ndi HTG, ukatenthetsa njira yapakatikati mu LTG, umakhazikika m'madzi afiriji.Madzi, atatha kugwedezeka, pamodzi ndi nthunzi ya refrigerant yomwe imapangidwa mu LTG, lowetsani mu condenser ndikukhazikika ndi madzi ozizira ndikusandulika kukhala madzi a refrigerant.Iyi ndi yofunika komanso yokonzedwa bwino ndi opanga mafakitale abwino kwambiri opangira mafakitale.
Madzi a furiji opangidwa mu condenser amadutsa U-paipi ndikulowa mu evaporator.Mbali ya refrigerant madzi vaporize chifukwa otsika kwambiri kuthamanga mu evaporator, pamene ambiri a iwo lotengeka ndi mpope refrigerant ndi sprayed pa evaporator chubu mtolo.The refrigerant madzi sprayed pa chubu mtolo ndiye zimatenga kutentha kwa madzi oyenda mu chubu mtolo ndi nthunzi nthunzi.Kutenthetsa ndi kusinthanitsa kutentha kumeneku ndi madera ofunikira kwambiri pakupanga makina abwino kwambiri opangira chiller.
Yankho lokhazikika lochokera ku LTG limayenda kudzera pa LTHE kulowa mu chotengera ndikupopera pachubu mtolo.Kenako, ataziziritsidwa ndi madzi oyenda mu mtolo wa chubu, yankho lokhazikika limatenga mpweya wa refrigerant kuchokera mu evaporator ndikukhala madzi osungunuka.Mwanjira imeneyi, yankho lokhazikika limakoka mosalekeza mpweya wa refrigerant womwe umapangidwa mu evaporator, ndikupangitsa kuti mpweya upitirire.Pakalipano, yankho lochepetsedwa limaperekedwa ndi mpope wa yankho ku HTG, kumene amawiritsa ndi kuyikanso.Chifukwa chake kuzungulira koziziritsa kumamalizidwa ndi mayamwidwe ambiri a LiBr ndipo kuzungulira kumabwereza.
