Abacwaningi e-Italy baklame uhlelo lwephampu lokushisa lomthombo wamanzi oluhloselwe ukukhiqiza ukupholisa, ukufudumeza kanye namanzi ashisayo asekhaya esitokisini sezindlu zomphakathi esakhiwe ngeminyaka yawo-1970-1990s. Umqondo wenoveli uhlanganisa amandla e-photovoltaic-thermal nesitoreji esishisayo futhi uthembisa i-coefficient yesizini yokusebenza engu-5.
Iqembu labacwaningi eliholwa yiNyuvesi yaseSapienza yaseRoma lenze uhlelo olusha lwephampu lokushisa lomthombo wamanzi (WSHP) oluhlanganisa amandla e-photovoltaic-thermal (PVT) kanye nesitoreji samandla ashisayo (TES) ukuze kukhiqizwe ukushisa okuhlanganisiwe, ukupholisa, ukukhiqizwa kwamanzi ashisayo asekhaya kanye nogesi.
Lolu hlelo lwakhiwe ngaphansi kwesambulela sephrojekthi yocwaningo lwe-RESHeat exhaswe yi-EU, okuhloswe ngayo ukuhlonza izixazululo ezivuselelekayo nezisebenza kahle ekushiseni nasekupholiseni, kanye nokukhiqizwa kwamanzi ashisayo asekhaya ezakhiweni zokuhlala ezinamafulethi amaningi. "Lo msebenzi ugxile kunguqulo yesiNtaliyane yephrojekthi ye-RESHeat," kusho ososayensi, bephawula ukuthi uhlelo oluhlongozwayo lwamukela ithangi lokugcina amanzi ashisayo esikhundleni seyunithi yokugcina ukushisa okungaphansi komhlaba njengezinguqulo zesistimu ezenzelwe amazwe aseYurophu ezindaweni eziphakeme.
Uhlelo luqukethe iphampu yokushisa yomthombo wamanzi ehlanganiswe namaphaneli e-photovoltaic epholile, amayunithi amabili okugcina - uhlangothi olulodwa lomthombo kanye nolunye uhlangothi lomthwalo - kanye nekhoyili yabalandeli. Ekucushweni kwesistimu ehlongozwayo, ukushisa okuphansi kwezinga lokushisa okuvela kumaphaneli kusetshenziselwa ukugcwalisa umthombo obandayo wepompo yokushisa ngesikhathi sokushisa. Ngesikhathi sokupholisa, ukushisa okweqile okuvela kumaphaneli e-PV, afinyelela emazingeni okushisa aphezulu, kudluliselwa ohlelweni lokukhiqiza amanzi ashisayo asekhaya.
"Amaphaneli e-PVT ahlinzeka ngokuhlangana okushisayo nogesi, ngamandla kagesi asetshenziselwa ukunika amandla i-WSHP, noma yiziphi izifudumezi eziyisipele, izisiza kanye nezikhala ze-condominium, kuyilapho ukushisa okuphansi okukhiqizwa ngesikhathi sasebusika kuhlanganiswa njengomthombo we-WSHP ngokusebenzisa i-TES," ithimba locwaningo lachaza. “Ngokuphambene, ngaphandle kwenkathi yokushisisa, kusukela ngo-April kuya ku-October, ukushisa okukhiqizwa yi-PVT kusetshenziselwa ukukhiqizwa kwe-DHW, egcinwa endaweni yokugcina impahla. Ekugcineni, enkathini yasehlobo, i-TES ixhunywe ku-DC, edingekayo ukuze kukhishwe ukushisa okweqile okukhiqizwa yi-HP ukuze kuphole isikhala.”
Zisebenzisa isofthiwe ye-TRNSYS kanye nendlela yokwenza izinqumo ngemibandela eminingi (i-MCDM), izifundiswa zenze ukulingisa okungu-184 ukuze zihlonze ubukhulu obufanele bezingxenye zesistimu ngenhloso yokuyibeka esakhiweni sokuhlala somphakathi esinamafulethi angu-13 akhiwa cishe ngo-1980 e-Palombara Sabina, eduze neRome, e-Italy.
"Isampula yereferensi iwumphumela wokuhlelwa kwedolobha okwaqalwa e-Italy ngeminyaka yama-60s ka-'900 ukungenelela kohlelo oluhlobene nezakhiwo zomphakathi ngaphambi kwemithethonqubo yokusebenza kwamandla ezakhiweni," bachaza, bengeza ngokuthi isakhiwo, okwamanje esithembele ohlelweni lokushisisa igesi eliphakathi nendawo, linomthwalo wokushisa wasebusika no-61 kW no-65 kW, ngokulandelanayo, kanye nenani labantu abangu-55 DHWl.
Ekulingiseni nasekuhlaziyweni kwe-MCDM, izifundiswa zicabangele amapharamitha abalulekile afana nathi i-coefficient of performance (COP), ingxenyenamba yelanga, ukusetshenziswa kwamandla okuyinhloko, ukonga amandla okuyinhloko, izindleko zesistimu nezokusebenza, kanye nemibandela yendawo yokusebenza. Abacwaningi bathole ukuthi ukucushwa kwesistimu okungcono kakhulu kungafinyelelwa ngamaphaneli angu-75 e-PVT anenani elingu-25 kW ahlukaniswe ngezintambo ezingu-15, ivolumu yethangi lebhafa exhunywe ohlangothini lomthombo we-HP ongu-3 m³, kanye nevolumu engu-1.5 m³ yesitoreji esishisayo se-DHW.
"Izindawo zokushisa ezihlonziwe zaziyi-25 C ye-DC, kanti i-HP, kokubili izinga lokushisa lokusebenza kwe-evaporator ne-condenser liyahlukahluka kuye ngezimo zangaphandle," baqhubeka bechaza. “Ohlangothini olubandayo, isukela ku-7 iye ku-20 C futhi iyahlukahluka kuye ngokwemisebe yesigameko kanye nokukhiqizwa kokushisa okuphansi kwezinga lokushisa kwamaphaneli e-PVT, kuyilapho ohlangothini olushisayo, kuyahlukahluka kuye ngokwezinga lokushisa langaphandle.”
Uhlelo luchazwe ocwaningweni "Incazelo yesistimu yepompo yokushisa yomthombo wamanzi ye-PVT ngokusebenzisa ukwenziwa kahle kwezingxenye ngazinye," eshicilelwe ku- Energy.
"Lo msebenzi uhlose ukusebenzisa isakhiwo e-Palombara Sabina njengecala lokuhlola lokuthuthukisa isistimu yokushisa ephakathi kwezimo zezulu ezipholile, ukuyiphakamisa njengendlela ekahle okufanele isetshenziswe ngezinga elikhulu kuzo zonke izindlu zomphakathi ezakhiwe phakathi nawo-1970-1990s, ngenhloso yokuvuselela amandla esikalini sasemadolobheni," kuphetha abacwaningi. “Izimpokophelo wukusebenza kahle kwesistimu, nge-COP yesizini encane engu-5, kanye nokumbozwa okungenani okungu-70 % emithonjeni evuselelekayo egxile ekulawuleni izinga lokushisa elizungezile.”
