Izazinzulu zisebenzise iifeni zokuvuthela ezimbini ezineepleyiti ezimbini ezidityanisiweyo ezidityanisiweyo ukwenza impompo yobushushu enokusebenza ngeendlela ezahlukeneyo zobushushu obuphantsi kunye neemeko zemitha yelanga. Inkqubo inomlinganiselo wemihla ngemihla wokusebenza kwe-3.24.
Iqela labaphandi bamazwe ngamazwe lenze inoveli impompo yobushushu bomoya welanga-moya wesibini (SAHP) ukulungiselela ukusetyenziswa kwamanzi okufudumeza.
Indlela entsha yokwenziwa kwenkqubo ilele ekusebenziseni isivutheli-moya esenza ukuba kuqhutywe ngenkani ukukhanya kwelanga kunye neemeko zokukhanya. Ukuhanjiswa okunyanzelwayo, okufana nokuhanjiswa kwendalo kwiimpompo zobushushu zesolar-moya ezimbini ezinemithombo-mbini, ikhupha umthombo we-thermal ojikelezayo kwisikhenkcisi.
"Olu pho nonongo lunegalelo elikhulu ekuqhubeleni phambili iteknoloji ye-SAHP, ivula indlela yezisombululo ezisebenzayo nezizinzileyo zokufudumeza amanzi kwimimandla eneemeko ezahlukeneyo zokuhlala," wongeze watsho.
I-Direct Expansion Modified Solar-Air dual-source Heat Pump (SAHP-MDX) ibandakanya i-rotary hermetic compressor, i-valve yokwandisa, kunye neekhoyili ze-condenser ezipholileyo zamanzi. Inkqubo yenoveli evaporator, eyilelwe ukoyisa umda weconvection yendalo, yakhiwe ngokupakisha iipleyiti ezingenanto ezimbini ezine-blower fan phakathi.
"Umoya we-ambient unyanzeliswa nge-double source bare plate evaporator kwi-SAHP-MDX ngabalandeli ababini abavuthelayo abaneemoto ezizimeleyo ze-35 W," izazinzulu zathi, ziphawula ukuba inkqubo inomqokeleli welanga we-1.6 m2 kunye ne-evaporator yonke indawo ye-3.2 m2. “I-rotary hermetic compressor, enamandla okufakwayo alinganisiweyo angama-910 W kunye nomthamo wokufudumeza oyi-3,500 W, inxinzelela isikhenkcisi somphunga (R410A).”
Impompo yobushushu inoveli ineendlela ezintathu zokusebenza. Omnye ngumthombo weSolar-Air iMode yeNdalo (i-SANM) apho inkqubo inokusebenza imini yonke xa imitha yelanga iphezulu, ivumela i-evaporator ukuba iqokelele amandla elanga kunye nobushushu obuvela kumoya ojikelezayo ngokusebenzisa ukuhanjiswa kwendalo.
I-Solar-Air source Forced Mode (SAFM) nayo isebenza imini yonke, kodwa xa ukukhanya kwelanga kungafumaneki ngokupheleleyo, i-evaporator isebenzisa i-convection enyanzelekileyo ukufunxa ubushushu obuvela kumoya oyingqongileyo, kunye namandla elanga. Xa i-insolation ingekho ngexesha lokutshona kwelanga okanye ebusuku, inkqubo isebenzisa i-Air-Source Forced Mode (AFM), njengoko i-evaporator ifunxa kuphela amandla obushushu ajikeleze emoyeni ngokuhambisa ngenkani.
Inkqubo yenoveli yavavanywa kumazantsi eIndiya, ngeentsuku ezintlanu zasebusika ngo-2021 kunye nangezinye iintsuku ezintlanu zasehlotyeni ngo-2022. Yayinemijikelo emihlanu yokufudumeza amanzi yonke imihla ukuzama uluhlu olupheleleyo lweendlela zokusebenza. Kumjikelo ngamnye bekufuneka ifudumeze iilitha ezingama-300 zamanzi ukusuka kubushushu bokuqala obungama-31 C ukuya kowokugqibela obungama-50 C.
Ngokweziphumo, kwimo ye-SANM le nkqubo ine-coefficient of performance (COP) ye-3.62, ngelixa i-SAFM kunye ne-AFM iphumelele i-3.37 kunye ne-3.05, ngokulandelelanayo. Umyinge we-COP yemihla ngemihla yempompo yokufudumala yenoveli, kuyo yonke imijikelo emihlanu yokufudumeza ngosuku yafunyanwa yi-3.24. Ixesha eliqhelekileyo lokufudumeza kwi-SANM yimizuzu eyi-163, imizuzu eyi-177 kwi-SAFM, kunye nemizuzu eyi-187 kwi-AFM.
Lilonke, i-SAHP-MDX ecetywayo igqithisa ngokuthelekiswa neempompo zobushushu ezikwimithombo emibini ekhoyo ngokusebenza,” laqukumbela iqela lophando. "Ingasetyenziswa njengendawo enokwenzeka yokufaka izicelo zokufudumeza amanzi kwiindawo zokwenyani zemozulu enemozulu engalindelekanga, ubushushu bomoya kunye nemitha yelanga."
Izazinzulu zichaze inkqubo kwiphepha elithi "Ukusetyenziswa ngokufanelekileyo komgangatho ophantsi womthombo womoya welanga ukufudumeza umpompo wamanzi kusetyenziswa i-evaporator enemithombo emibini ene-convection enyanzelweyo," esanda kupapashwa. UNxibelelwano lwaMazwe ngaMazwe kuBubushushu kunye nokuThuthukiswa koBuninzi. Abaphandi bavela eIndiya eBannari Amman Institute of Technology, eSri Krishna College of Technology, kunye neYunivesithi yaseMalaysia yaseSunway.
