Ukunciphisa ukusetyenziswa kwamandla okufudumeza, ukungena komoya kunye neenkqubo zomoya (i-HVAC) kuya kubaluleke kakhulu ngenxa yokunyuka kweendleko zamafutha eefosili kunye neenkxalabo zokusingqongileyo. Ke ngoko, ukufumana iindlela ezintsha zokunciphisa ukusetyenziswa kwamandla kwizakhiwo ngaphandle kokubeka esichengeni intuthuzelo kunye nomgangatho womoya wangaphakathi ngumngeni oqhubekayo wophando. Enye indlela eqinisekisiweyo yokuphumeza ukusebenza kakuhle kwamandla kwiinkqubo ze-HVAC kukuyila izixokelelwano ezisebenzisa ulungelelwaniso lwenoveli lwamacandelo enkqubo esele ikho. Ingqeqesho nganye ye-HVAC ineemfuno zoyilo ezikhethekileyo kwaye nganye inika amathuba okonga amandla. Iinkqubo ze-HVAC ezisebenza ngamandla zinokudalwa ngokuphinda kuqwalaselwe iisistim zemveli ukuze kusetyenziswe ngobuchule iindawo ezikhoyo zenkqubo. Uphando lwakutsha nje luye lwabonisa ukuba indibaniselwano yetekhnoloji ekhoyo yokupholisa umoya inokunika izisombululo ezisebenzayo zogcino lwamandla kunye nentuthuzelo yobushushu. Eli phepha liphanda kwaye liphonononga ubugcisa obuhlukeneyo kunye neendlela, kwaye libonisa amandla abo okuphucula ukusebenza kweenkqubo ze-HVAC ukwenzela ukunciphisa ukusetyenziswa kwamandla. Kwisicwangciso ngasinye, inkcazo emfutshane inikezelwa kuqala kwaye emva koko ngokuphonononga izifundo zangaphambili, impembelelo yaloo ndlela kwi-HVAC yokonga amandla iyaphandwa. Ekugqibeleni, uphononongo lokuthelekisa phakathi kwezi ndlela luyenziwa.
5.Iinkqubo zokubuyisela ubushushu
Imigangatho ye-ASHRAE icebisa ubungakanani bomoya ococekileyo ofunekayo kwizakhiwo ezahlukeneyo. Umoya ongaguquguqukiyo unyusa kakhulu iimfuno zokupholisa zesakhiwo, nto leyo ekhokelela ekwandeni kokusetyenziswa kwamandla ngokubanzi kweenkqubo zeHVAC zesakhiwo. Kwisityalo esisembindini sokupholisa, isixa somoya omtsha simiselwa ngokusekelwe kwimida ephezulu yoxinaniso lwezingcolisi zomoya zangaphakathi ezihlala ziphakathi kwe-10% kunye ne-30% yesantya sokuhamba komoya sisonke [69]. Kwizakhiwo zanamhlanje ilahleko yokungena komoya inokuba ngaphezulu kwe-50% yelahleko ye-thermal iyonke [70]. Nangona kunjalo, ukungena komoya ngoomatshini kunokutya ukuya kuthi ga kwi-50% yamandla ombane asetyenziswa kwizakhiwo zokuhlala [71]. Ukongeza, kwimimandla eshushu kunye nefumileyo iinkqubo zokungenisa umoya zoomatshini ezifanelekileyo malunga ne-20-40% yosetyenziso lwamandla lulonke lweenkqubo zomoya [72]. Nasif et al. [75] ufunde ukusetyenziswa kwamandla onyaka we-air conditioner kunye ne-enthalpy / i-membrane exchanger heat and thelekisa kunye ne-air conditioning eqhelekileyo. Bafumanise ukuba kwimozulu efumileyo, ukonga amandla ngonyaka ukuya kuthi ga kwi-8% kunokwenzeka xa usebenzisa i-membrane yokutshintshiselana kobushushu endaweni yenkqubo yesiqhelo ye-HVAC.
I-Holtop iyonke yokutshintshiselana kobushushu yenziwe ngephepha le-ER elibonakaliswe kukunyakama okuphezulu, ukuxinwa komoya okulungileyo, ukuxhathisa okugqwesileyo kweenyembezi, kunye nokumelana nokwaluphala. Ukucocwa phakathi kweentsinga kuncinci kakhulu, ngoko ke kuphela iimolekyuli zokufuma ezinobubanzi obuncinci zinokudlula, iimolekyuli zevumba ezinobubanzi obukhulu azikwazi ukudlula kuyo. Ngale ndlela, iqondo lobushushu kunye nokufuma kunokubuyiselwa kakuhle, kwaye kuthintele ungcoliseko ukuba lungene kumoya omtsha.
6.Isiphumo sokuziphatha kokwakha
Ukusetyenziswa kwamandla kwenkqubo ye-HVAC ayixhomekanga kuphela ekusebenzeni kwayo kunye neeparitha zokusebenza, kodwa nakwiimpawu zokufudumeza kunye nokupholisa imfuno kunye nokuziphatha okuguquguqukayo kwe-thermo yesakhiwo. Owona mthwalo weenkqubo zeHVAC ungaphantsi kunoko uyilwe ngamaxesha amaninzi okusebenza ngenxa yendlela yokuziphatha. Ke ngoko, ezona zinto zibalulekileyo ezinegalelo ekucuthekeni kokusetyenziswa kwamandla e-HVAC kwisakhiwo esinikiweyo kulawulo olululo lwemfuno yokufudumeza kunye nokupholisa. Ulawulo oludityanisiweyo lwamacandelo omthwalo wokupholisa kwisakhiwo, afana nemitha yelanga, ukukhanya kunye nomoya omtsha, kunokubangela ukongiwa kwamandla okubalulekileyo kwiplanti yokupholisa yesakhiwo. Kuqikelelwa ukuba malunga ne-70% yokonga amandla kunokwenzeka ngokusetyenziswa kobugcisa boyilo olungcono ukulungelelanisa imfuno yesakhiwo kunye nomthamo wenkqubo yeHVAC. Korolija et al. yaphanda ubudlelwane phakathi kwesakhiwo sokufudumeza kunye nomthwalo wokupholisa kunye nokusetyenziswa kwamandla okulandela ngeenkqubo ezahlukeneyo zeHVAC. Iziphumo zabo zibonise ukuba ukusebenza kwamandla okwakha akunakuvavanywa kuphela ngokusekelwe kwimfuno yokufudumeza kwesakhiwo kunye nokupholisa ngenxa yokuxhomekeka kwayo kwiimpawu ze-HVAC zokushisa. Huang etal. iphuhliswe kwaye ivavanye imisebenzi yolawulo lwamandla emihlanu ecwangcisiweyo ngokwendlela yokuziphatha kwesakhiwo kwaye iphunyezwe kwi-variabl yomthamo womoya wenkqubo ye-HVAC. Iziphumo zabo zokulinganisa zibonise ukuba ukonga amandla kwi-17% kunokufezekiswa xa inkqubo iqhutywa ngale misebenzi yolawulo.
Iinkqubo eziqhelekileyo ze-HVAC zithembele kakhulu kumandla enziwe kumafutha efosili, aphela ngokukhawuleza. Oku kunye nemfuno ekhulayo yeziseko ezingundoqo ezinexabiso eliphantsi kunye nezixhobo zombane zenze imfuneko yofakelo olutsha kunye nohlengahlengiso olukhulu kwizakhiwo ekuhlala kuzo abantu ukuze kuphunyezwe ukusebenza kakuhle kwamandla kunye nokuzinza kokusingqongileyo. Ke ngoko, ukufumana iindlela ezintsha eziya kwizakhiwo eziluhlaza ngaphandle kokubeka esichengeni intuthuzelo kunye nomgangatho womoya wangaphakathi kuhlala kungumngeni wophando kunye nophuhliso. Ukucutha okufikelelekayo kokusetyenziswa kwamandla kunye nokwandiswa kokuthuthuzela kwabantu kwizakhiwo kuxhomekeke ekusebenzeni kweenkqubo zeHVAC. Enye indlela eqinisekisiweyo yokuphumeza ukusebenza kakuhle kwamandla kwiinkqubo ze-HVAC kukuyila izixokelelwano ezisebenzisa ulungelelwaniso lwenoveli lwamacandelo enkqubo esele ikho. Uphando lwakutsha nje lubonise ukuba indibaniselwano yetekhnoloji ekhoyo yokupholisa umoya inakho ukunika izisombululo ezisebenzayo zogcino lwamandla kunye nokuthuthuzela ubushushu. Kweli phepha iindlela ezahlukeneyo zokonga amandla kwiinkqubo zeHVAC zaphandwa kwaye amandla azo okuphucula ukusebenza kwenkqubo kwaxoxwa. Kwafunyaniswa ukuba izinto ezininzi ezifana neemeko zemozulu, induduzo ye-thermal elindelekileyo, iindleko zokuqala kunye nenkunzi, ukufumaneka kwemithombo yamandla kunye nesicelo.
