Iimpompo zoBubushushu obuPhezulu obuVuselelwa-Amandla ziLona khetho lutshiphu kakhulu kuMphunga woShishino

Uphando olutsha oluvela e-Austria luthelekise iindlela ezahlukeneyo zokuvelisa ubushushu kwimizi-mveliso kwaye lufumanise ukuba iimpompo zobushushu zomoya okanye zelanga zezona zisombululo zingabizi kakhulu kwaye zinobubele kokusingqongileyo.

Iqela lophando kwiYunivesithi yaseJohannes Kepler yaseLinz e-Austria licebise ukuba abenzi bomgaqo-nkqubo baxhase iiprojekthi zoshishino usebenzisa iimpompo zokushisa ukuvelisa i-steam kunye nentlawulo ye-€ 3 (i-$ 3.2) ngegigajoule (GJ). Eso sisiphumo sohlalutyo lwamaxabiso empembelelo yokusingqongileyo yeendlela ezahlukeneyo zomphunga, ezifumanise ukuba iimpompo zobushushu ezisebenza ngamandla ahlaziyekayo zibe zezona ndleko zincinci. "Ukuthathela ingqalelo i-43.20 Terajoules (TJ) eveliswe ngexesha lokuphila kwesityalo, i-subsidy ye-129,600 ye-XNUMX ingahlawulwa," abaphandi bathi.

Nangona uphando lujolise kumandla omoya njengomthombo wombane ohlaziyekayo, umbhali-mbhali uLukas Zeilerbauer uxelele pv imagazini ukuba ukusebenzisa amandla elanga kufuneka kuvelise iziphumo ezifanayo kakhulu. "I-PV ngokubanzi ineempembelelo eziphezulu kukufudumala kwehlabathi kunamandla omoya, kodwa ngokuqinisekileyo iphantsi kakhulu kubaphathi bamandla efosili," watsho. "I-PV ibonisa ixabiso lesithunzi le-euro eyi-1.46 (i-$1.58), ngoko iphantse yafana nomoya."

Kwiphepha elithi "Uvavanyo lomjikelo wobomi kunye neendleko zesithunzi somphunga oveliswe yimpompo yobushushu obuphezulu kwishishini," epapashwe IMveliso eZinzileyo kunye nokuSetyenziswa, izazinzulu zachaza ukuba zisebenzisa i-Life Cycle Assessments (LCA) ukuthelekisa iindlela ezahlukeneyo zokuvelisa i-steam ezisetyenziswa kwi-industrial scale, kubandakanywa iimpompo zokushisa eziphezulu (HTHPs). Ezinye iindlela zokwenza umphunga ziquka iinkqubo ze-steam-biogas, iinkqubo eziqinileyo ze-biomass, kunye nezinye iinkqubo ezisekelwe kwigesi yendalo kunye ne-oyile ye-fuel light.

Abaphandi baqwalasela iimeko ezimbini ezahlukeneyo, enye apho i-steam iveliswa ngoxinzelelo lwe-2-bar kunye noxinzelelo lwe-5-bar. Kuzo zombini ezi meko, bathathele ingqalelo ukusetyenziswa kombane womoya okanye wegridi.

"Umcimbi kunye neendlela ze-LCA kukuba ngokuqhelekileyo ziquka iindidi ezingaphezu kweshumi zomonakalo kwaye ngoko ke iziphumo ezahlukeneyo ezijongene neendawo ezahlukeneyo, kwaye kunzima ukufumana izinto ezinobunzima phakathi kwezi ziphumo ezihluke kakhulu," kuchaza iqela lophando. “Nangona kunjalo, iingcali ziye zacebisa ukuba kusetyenziswe amaxabiso emali kwangethuba. Enye yezo ndlela lixabiso lesithunzi, elinoluvo olusisiseko lokuba ekugqibeleni urhulumente, omele abantu bakhe, kufuneka ‘alungise’ umonakalo wokusingqongileyo ngoko ke unomdla wokunciphisa ezi ndleko.”

Akumangalisi ukuba izifundiswa zifumene ukudibanisa iimpompo zokushisa kunye namandla omoya anexabiso eliphantsi kakhulu le-1.44 ye-GJ kwi-2-bar bar, kunye ne-2.24 € kwi-5-bar case. Ukutshintsha amandla omoya kumxube wegridi yaseSpain kubangele amaxabiso eLCA e-3.83 kunye ne-6.23 € ngokulandelanayo. Ngokuthelekisa, ukusetyenziswa kwe-biomass eqinile yenkqubo yomphunga kunexabiso lokusingqongileyo le-17.2 ye-GJ nganye, kunye nexabiso le-oyile ekhanyayo ye-9.81 €.

Ukujonga ngokubanzi kwimiphumo yokusingqongileyo yeendlela ezahlukeneyo, uphando lufumene eyona nto ingcono kakhulu yokunciphisa i-98% ye-greenhouse emissions. Nangona kunjalo, amanye amanyathelo okusingqongileyo abonise iziphumo ezixubene ngakumbi, njengoko, umzekelo, iziphumo ezinxulumene nobutyhefu ziguquguquka phakathi kweempompo zobushushu kunye nebenchmarks.

"Isiphumo esingalindelekanga kukuba i-fluid esebenzayo kunye nokuvuza kwayo ayizange ibe negalelo elibalulekileyo kubushushu behlabathi kodwa yayiphantse ibe noxanduva lokuphela kwe-ozone," abaphandi bagxininisa. Bacingela ukusetyenziswa kwe-R134a njengolwelo olusebenzayo, njengoko ikuphela kolwazi olufumanekayo kuncwadi lwezifundo lwe-LCA.

I-HTHP ehlolisiswe kolu phononongo yenzelwe ukuphunyezwa kumgca wokuchola wesityalo sentsimbi eSpain. Inomthamo wokubonelela ngobushushu obungama-250 kW kwaye ibandakanya itanki edanyazayo eyilelwe ngokwesiqhelo ukuvelisa umphunga, kunye nempompo yokujikeleza.

"Nangona i-steam-generating pump pump-heat pump ecatshangelwayo kolu cwaningo yenzelwe ukuba iphunyezwe kumgca wokugqiba isityalo sensimbi, iziphumo zolu pho nonongo zingasetyenziswa kwamanye amacandelo amaninzi amashishini, njengoko i-steam ingumsinga wokushisa wendalo yonke kwiinkqubo ezininzi zoshishino," abaphengululi bachaza. "Le mpompo yobushushu inokusetyenziswa kuyo nayiphi na enye inkqubo efuna umphunga woxinzelelo olusezantsi ukuya kuthi ga kwi-5 bar."
