Abaphandi base-Italiyane bayile inkqubo yempompo yobushushu yomthombo wamanzi eyenzelwe ukuvelisa ukupholisa, ukufudumeza kunye namanzi ashushu asekhaya kwindawo yokuhlala yokuhlala eyakhiwe ngexesha le-1970s-1990s. Ingcamango yenoveli idibanisa amandla e-photovoltaic-thermal kunye nokugcinwa kwe-thermal kwaye ithembisa i-coefficient ye-seasonal coefficient yokusebenza kwe-5.
Iqela labaphandi elikhokelwa yiYunivesithi yaseSapienza yaseRoma liye laqulunqa inkqubo entsha yempompo yokufudumala yamanzi (WSHP) edibanisa amandla e-photovoltaic-thermal (PVT) kunye nokugcinwa kwamandla okushisa (TES) ukwenzela ukuveliswa kokufudumeza okudibeneyo, ukupholisa, ukuveliswa kwamanzi ashushu asekhaya kunye nombane.
Inkqubo yaphuhliswa phantsi kwesambulela seprojekthi yophando ye-EU-fund ye-RESHeat, ejolise ekuchongeni izisombululo ezihlaziyiweyo kunye nezamandla ezisebenza ngokufanelekileyo zokufudumeza kunye nokupholisa, kunye nokuveliswa kwamanzi ashushu asekhaya kwizakhiwo zokuhlala ezininzi. "Lo msebenzi ugxile kwinguqulo yesiTaliyane yeprojekthi ye-RESHeat," izazinzulu zathi, ngokuqaphela ukuba inkqubo ecetywayo ithatha itanki yokugcina amanzi ashushu endaweni yokugcinwa kobushushu obuphantsi komhlaba njengeenguqulelo zenkqubo eziphuhliswe kumazwe aseYurophu kwiindawo eziphezulu.
Inkqubo iqulethe ipompo yokushisa yomthombo wamanzi edibeneyo kunye neepaneli ze-photovoltaic ezipholileyo, iiyunithi ezimbini zokugcina - elinye icala lomthombo kunye nomthwalo wecala - kunye ne-fan coil. Kwinkqubo ecetywayo yokucwangciswa, ukushisa okuphantsi kweqondo lokushisa ukusuka kwiipaneli kusetyenziselwa ukuzalisa iqula elibandayo lempompo yokushisa ngexesha lokufudumala. Ngexesha lokupholisa, ubushushu obugqithisileyo obuvela kwiipaneli zePV, ezifikelela kumaqondo obushushu aphezulu, zigqithiselwa kwinkqubo yokuvelisa amanzi ashushu asekhaya.
"Iipaneli ze-PVT zibonelela ngokuhlanganiswa kwe-thermal kunye nombane, kunye namandla ombane asetyenziselwa ukunika amandla i-WSHP, naziphi na izifudumezi ezigcina i-backup, abancedisi kunye neendawo zekhondom, ngelixa ubushushu obuphantsi obuveliswa ngexesha lasebusika bufakwe njengomthombo we-WSHP ngokusebenzisa i-TES, "iqela lophando lachaza. Ngokwahlukileyo koko, ngaphandle kwexesha lokufudumeza, ukususela ngo-Epreli ukuya ku-Oktobha, ubushushu obuveliswa yi-PVT bubotshelelwa kwimveliso yeDHW, egcinwa kwindawo yokugcina ezinikeleyo. Okokugqibela, ehlotyeni, i-TES iqhagamshelwe kwi-DC, efunekayo ukukhupha ubushushu obugqithisileyo obuveliswe yi-HP yokupholisa indawo.
Ukusebenzisa isoftware yeTRNSYS kunye neendlela ezininzi zokwenziwa kwezigqibo (MCDM), izifundiswa ziqhube imilinganiso eyi-184 ukuchonga ubungakanani obufanelekileyo bamacandelo enkqubo ngenjongo yokuyithumela kwisakhiwo sokuhlala soluntu esinamagumbi ali-13 akhiwe malunga no-1980 ePalombara Sabina, kufutshane neRoma, eItali.
"Isampulu yesalathiso sisiphumo sokucwangciswa kwedolophu eqaliswe e-Italiya kwiminyaka engama-60 ye-900 yokungenelela kwenkqubo ehambelana nezakhiwo zentlalo ngaphambi kwemimiselo yokusebenza kwamandla kwizakhiwo," bachaza, bongeza ukuba isakhiwo, okwangoku sithembele kwinkqubo yokufudumeza igesi ephakathi, inomthwalo wokushisa ebusika nasehlotyeni we-61 kW kunye ne-65 kW, ngokulandelelana, kunye ne-55 ye-DHWl yabantu aba-50.
Kwimilinganiso kunye nohlalutyo lwe-MCDM, izifundiswa ziqwalasela iiparitha eziphambili ezifana nathi i-coefficient of performance (COP), i-fraction yelanga, ukusetyenziswa kwamandla okuphambili, ukugcinwa kwamandla okuphambili, inkqubo kunye neendleko zokusebenza, kunye neendlela zokucwangcisa indawo. Abaphandi bafumanise ukuba ulungelelwaniso lwenkqubo olungcono lunokufezekiswa ngeepaneli ze-PVT ezingama-75 ezipheleleyo ze-25 kW ezahlulwe kwiintambo ze-15, umthamo wetanki ye-buffer edityaniswe kwicala lomthombo we-HP ye-3 m³, kunye nomthamo we-1.5 m³ ye-DHW yokugcina i-thermal.
"Iiqondo lokushisa elichongiweyo liyi-25 C ye-DC, ngelixa i-HP, zombini ukushisa okusebenzayo kwe-evaporator kunye ne-condenser kuyahluka ngokwemiqathango yangaphandle," bachaza ngakumbi. Kwicala elibandayo, zisusela kwi-7 ukuya kwi-20 C kwaye ziyahluka ngokwemitha yezehlo kunye nobushushu obuphantsi bemveliso yeepaneli zePVT, ngelixa kwicala elishushu, ziyahluka ngokobushushu bangaphandle.
Inkqubo yachazwa kuphononongo "Inkcazo ye-PVT edityaniswe nenkqubo yempompo yobushushu bomthombo wamanzi ngokulungiswa kwamacandelo athile," epapashwe amandla.
"Lo msebenzi ujolise ekusebenziseni isakhiwo ePalombara Sabina njengetyala lokuvavanya ukuphuculwa kwenkqubo yokufudumala ephakathi kwimozulu epholileyo, ukuyiphakamisa njengendlela efanelekileyo yokusetyenziswa kwinqanaba elikhulu kwi-stock yentlalo yoluntu eyakhiwe ngexesha le-1970-1990s, ngombono wokulungiswa kwamandla kwinqanaba ledolophu," abaphandi baqukumbela. “Okujoliswe kuko kukusebenza kwenkqubo, kunye neCOP yexesha elithile eli-5 ubuncinane, kunye nobuncinane be-70% yokhuselo oluvela kwimithombo ehlaziyekayo ejolise kulawulo lobushushu obukhoyo.”
