Ukunciphisa ukusetshenziswa kwamandla kwezinhlelo zokushisisa, ukungena komoya kanye nezipholile (i-HVAC) kuya ngokuya kubaluleke kakhulu ngenxa yokukhuphuka kwezindleko zamafutha ezinsalela kanye nokukhathazeka kwemvelo.Ngakho-ke, ukuthola izindlela ezintsha zokunciphisa ukusetshenziswa kwamandla ezakhiweni ngaphandle kokuyekethisa ukunethezeka kanye nekhwalithi yomoya wasendlini kuyinselele yocwaningo eqhubekayo.Enye indlela efakazelwe yokufeza ukusebenza kahle kwamandla ezinhlelweni ze-HVAC ukuklama amasistimu asebenzisa ukumiswa kwamanoveli kwezingxenye zesistimu ezikhona.Isiyalo ngasinye se-HVAC sinezidingo ezithile zokuklama futhi ngasinye sinikeza amathuba okonga amandla.Amasistimu e-HVAC awonga amandla angadalwa ngokulungisa kabusha amasistimu avamile ukuze kusetshenziswe amasu ezingxenye zesistimu ezikhona.Ucwaningo lwakamuva lubonise ukuthi inhlanganisela yobuchwepheshe be-air conditioning ekhona inganikeza izixazululo ezisebenzayo zokongiwa kwamandla kanye nokunethezeka kokushisa.Leli phepha liphenya futhi libuyekeze ubuchwepheshe obuhlukene nezindlela, futhi libonisa amandla azo okuthuthukisa ukusebenza kwezinhlelo ze-HVAC ukuze kwehliswe ukusetshenziswa kwamandla.Kusu ngalinye, kuqale kwethulwe incazelo emfushane bese ngokubuyekeza izifundo ezedlule, umthelela waleyo ndlela ekongeni amandla we-HVAC uyaphenywa.Ekugcineni, kwenziwa ucwaningo lokuqhathanisa phakathi kwalezi zindlela.
5.Amasistimu okubuyisela ukushisa
Izindinganiso ze-ASHRAE zincoma inani lomoya ohlanzekile odingekayo wezakhiwo ezahlukene.Umoya ongenambandela unyusa kakhulu izidingo zokupholisa zesakhiwo, okuholela ekwandeni kokusetshenziswa kwamandla okuphelele kwezinhlelo ze-HVAC zesakhiwo.Embonini yokupholisa emaphakathi, inani lomoya omusha linqunywa ngokusekelwe emikhawulweni ephezulu yokugxila kokungcoliswa komoya kwangaphakathi okuvamise ukuba phakathi kuka-10% no-30% wenani eliphelele lokugeleza komoya [69].Ezakhiweni zesimanje ukulahlekelwa komoya-mpilo kungaba ngaphezu kwamaphesenti angama-50 wokulahlekelwa okuphelele kokushisa [70].Kodwa-ke, ukungena komoya ngomshini kungadla amandla kagesi afinyelela ku-50% asetshenziswa ezakhiweni zokuhlala [71].Ukwengeza, ezindaweni ezishisayo nezinomswakama izinhlelo zokungenisa umoya ngemishini ezifanele mayelana ne-20-40% yengqikithi yokusetshenziswa kwamandla kwezinhlelo zokupholisa umoya[72].Nasif et al.[75] itadishe ukusetshenziswa kwamandla kwaminyaka yonke kwesipholile somoya kuhlanganiswe ne-enthalpy/membrane heat exchanger futhi yaqhathanisa nesipholile somoya esivamile.Bathole ukuthi esimweni sezulu esiswakeme, ukonga amandla ngonyaka afika ku-8% kungenzeka uma usebenzisa isishintshi sokushisa ulwelwesi esikhundleni sohlelo oluvamile lwe-HVAC.
Isishintshi sokushisa esiphelele se-Holtopyenziwe ngephepha le-ER elibonakala ngokungena kwamanzi aphezulu, ukucinana komoya okuhle, ukumelana nezinyembezi okuhle kakhulu, nokumelana nokuguga.Ukuvunyelwa phakathi kwemicu kuncane kakhulu, ngakho-ke ama-molecule womswakama we-diameter encane kuphela angadlula, ama-molecule ephunga anobubanzi obukhulu awakwazi ukudlula kuwo.Ngale ndlela, izinga lokushisa kanye nomswakama kungabuyiselwa kahle, futhi kuvimbele ukungcola kungene emoyeni omusha.
6.Umphumela wokuziphatha kokwakha
Ukusetshenziswa kwamandla kwesistimu ye-HVAC akuncikile kuphela ekusebenzeni kwayo nemingcele yokusebenza, kodwa futhi nasezicini zesidingo sokushisisa nokupholisa kanye nokuziphatha okuguquguqukayo kwe-thermo kwesakhiwo.Umthwalo wangempela wamasistimu e-HVAC ungaphansi kwalokho oklanywe ngawo ezikhathini eziningi zokusebenza ngenxa yokuziphatha kokwakha.Ngakho-ke, izinto ezibaluleke kakhulu ezinomthelela ekuncishisweni kokusetshenziswa kwamandla e-HVAC esakhiweni esithile ukulawula okufanele kwesidingo sokushisisa nokupholisa.Ukulawulwa okudidiyelwe kwezingxenye zokupholisa kwesakhiwo, njengemisebe yelanga, ukukhanya nomoya omusha, kungaholela ekongeni kwamandla okubalulekile endaweni yokupholisa yesakhiwo.Kulinganiselwa ukuthi cishe u-70% yokonga amandla kungenzeka ngokusetshenziswa kobuchwepheshe bedizayini obungcono ukuxhumanisa isidingo sebhilidi namandla esistimu yayo ye-HVAC.Korolija et al.iphenya ubudlelwano phakathi kokushisisa kwesakhiwo nomthwalo wokupholisa kanye nokusetshenziswa kwamandla okwalandela namasistimu ahlukene e-HVAC.Imiphumela yabo ibonise ukuthi ukusebenza kwamandla wesakhiwo akukwazi ukulinganisa kuphela ngokusekelwe esimisweni sokushisisa nesokupholisa esakhiweni ngenxa yokuncika kwayo ezicini ezishisayo ze-HVAC.Huang etal.ithuthukiswe futhi yahlola imisebenzi emihlanu yokulawulwa kwamandla ehlelwe ngokuya ngokuziphatha kwesakhiwo futhi yasetshenziswa kusistimu ye-HVAC yevolumu yomoya eguquguqukayo.Imiphumela yabo yokulingisa ibonise ukuthi ukonga amandla okungu-17% kungafinyelelwa lapho uhlelo lusetshenziswa ngale misebenzi yokulawula.
Amasistimu avamile we-HVAC athembele kakhulu emandleni akhiqizwa kumafutha ezinto ezimbiwa phansi, aphela ngokushesha.Lokhu kanye nesidingo esikhulayo sengqalasizinda eyongayo kanye nemishini sekwenze kwadingeka ukuthi kufakwe izinto ezintsha kanye nokulungiswa kabusha kwezakhiwo ezihlala abantu abaningi ukuze kuzuzwe ukusebenza kahle kwamandla kanye nokusimama kwemvelo.Ngakho-ke, ukuthola izindlela ezintsha eziya ezakhiweni eziluhlaza ngaphandle kokuyekethisa ukunethezeka kanye nekhwalithi yomoya wasendlini kuseyinselele yocwaningo nentuthuko.Ukwehliswa okuphelele okufinyelelekayo kokusetshenziswa kwamandla kanye nokuthuthukiswa kokunethezeka komuntu ezakhiweni kuncike ekusebenzeni kwamasistimu e-HVAC.Enye indlela efakazelwe yokufeza ukusebenza kahle kwamandla ezinhlelweni ze-HVAC ukuklama amasistimu asebenzisa ukumiswa kwamanoveli kwezingxenye zesistimu ezikhona.Ucwaningo lwakamuva lubonise ukuthi inhlanganisela yobuchwepheshe be-air conditioning ekhona inganikeza izixazululo ezisebenzayo zokongiwa kwamandla kanye nokunethezeka kokushisa.Kuleli phepha kwaphenywa ngamasu ahlukahlukene okonga amandla ezinhlelo ze-HVAC futhi kwaxoxwa nangamandla azo okuthuthukisa ukusebenza kwesistimu.Kutholwe ukuthi izici eziningana ezifana nezimo zezulu, ukunethezeka okushisayo okulindelekile, izindleko zokuqala nezemali, ukutholakala kwemithombo yamandla kanye nesicelo.
