Iinkqubo ze-HVAC zixhomekeke kwizixhobo zokungenisa umoya zokufudumeza indawo kunye ne-air conditioning, kuba ii-chiller kunye neebhoyila ngokwazo azikwazi ukuzisa isiphumo sokufudumeza okanye sokupholisa apho kufuneka khona.Ukongezelela, iinkqubo zokungenisa umoya ziqinisekisa ukubonelelwa rhoqo komoya omtsha kwiindawo zangaphakathi.Ngokusekelwe kuxinzelelo kunye neemfuno zokuhamba komoya kwisicelo ngasinye, nokuba kusetyenziswe ifeni okanye i-blower.
Ngaphambi kokuba uxoxe ngeentlobo eziphambili zabalandeli kunye nabavuthela, kubalulekile ukuqonda umahluko phakathi kweengcamango zombini.I-American Society of Mechanical Engineers (ASME) ichaza abalandeli kunye nezivuthela ngokusekelwe kumlinganiselo phakathi koxinzelelo lokukhupha kunye noxinzelelo lokufunxa.
- Umlandeli:Umlinganiselo woxinzelelo ukuya kuthi ga kwi-1.11
- Isivutheli:Umlinganiselo woxinzelelo ukusuka kwi-1.11 ukuya kwi-1.2
- Isicinezeli:Umlinganiselo woxinzelelo ungaphezulu kwe-1.2
Iifeni kunye nezivuthela ziyimfuneko ukuze umoya woyise ukuchasana nokuhamba okubangelwa ngamacandelo afana neepayipi kunye needampers.Kukho iintlobo ezininzi ezikhoyo, nganye ilungele usetyenziso oluthile.Ukukhetha uhlobo oluchanekileyo kunceda ukwandisa ukusebenza kwe-HVAC, ngelixa ukhetho olubi lukhokelela kwinkcitho yamandla.
Ngaba usebenzisa izixhobo ezifanelekileyo zokungenisa umoya?
Qhagamshelana nathi
Iintlobo zeeFani
Iifeni zinokuhlelwa zibe yi-centrifugal okanye i-axial ngokusekwe kwindlela abaseka ngayo ukuhamba komoya.Kwelinye icala, kukho iindidi ezisezantsi kudidi ngalunye, kwaye ukukhetha ifeni ehambelana nesicelo kubalulekile kufakelo olusebenza kakhulu lwe-HVAC.
Le theyibhile ilandelayo ishwankathela iintlobo eziphambili zeefeni ze-centrifugal: i-radial, igophe langaphambili, igophe elingasemva kunye nohlobo lwe-airfoil.
| UHLOBO LWEFAN | INKCAZO |
| Iradial | -Uxinzelelo oluphezulu kunye nokuhamba okuphakathi -Ukunyamezela uthuli, ukufuma kunye nobushushu, kuyenza ilungele ukusetyenziswa kwimizi-mveliso -Ukusetyenziswa kwamandla kwandisa kakhulu kunye nokuhamba komoya |
| Phambili igophe | -Uxinzelelo oluphakathi kunye nokuhamba okuphezulu -Ifanelekile kwiinkqubo zeHVAC ezinoxinzelelo oluphantsi ngokwentelekiso, njengeeyunithi ezipakishiweyo zophahla -Iyalunyamezela uthuli, kodwa ayifanelanga ukusetwa kwemizi-mveliso eqatha -Ukusetyenziswa kwamandla kwandisa kakhulu kunye nokuhamba komoya |
| Ngasemva igophe | -Uxinzelelo oluphezulu kunye nokuhamba okuphezulu -Amandla ayasebenza -Ayifumani ukwanda okukhulu koxinzelelo kunye nokuhamba komoya -I-HVAC kunye nezicelo zemizi-mveliso, nazo zinyanzeliswe iinkqubo zoyilo |
| Ifoyile yomoya | -Uxinzelelo oluphezulu kunye nokuhamba okuphezulu -Amandla ayasebenza -Yenzelwe izicelo ezinomoya ococekileyo |
Kwelinye icala, abalandeli be-axial flow bahlelwa ngokweepropeller, i-tube axial kunye ne-vane axial.
| UHLOBO LWEFAN | INKCAZO |
| Ipropeller | -Uxinzelelo oluphantsi kunye nokuhamba okuphezulu, ukusebenza kakuhle okuphantsi -Ifanelekile kumaqondo obushushu aphakathi -Ukuhamba komoya kuncitshiswa kakhulu ukuba uxinzelelo lwe-static luyanda. -Usetyenziso oluqhelekileyo lubandakanya iifeni zokukhupha, iicondenser zangaphandle kunye neenqaba zokupholisa |
| Umbhobho axial | -Uxinzelelo oluphakathi kunye nokuhamba okuphezulu -Izindlu ze-Cylindrical kunye ne-clean encinci ene-fan blades ukuphucula ukuhamba komoya -Isetyenziswa kwi-HVAC, iinkqubo zokukhupha kunye nokumisa izicelo |
| Vane axial | -Uxinzelelo oluphezulu kunye nokuhamba okuphakathi, ukusebenza kakuhle -Ngokwenyama efana ne-tube axial fans, ukudibanisa i-vanes yesikhokelo ekuthatheni ukuphucula ukusebenza kakuhle -Ukusetyenziswa okuqhelekileyo kubandakanya i-HVAC kunye neenkqubo zokukhupha, ngakumbi apho kufuneka uxinzelelo oluphezulu |
Ngokhetho olubanzi kangaka lwabalandeli, kukho isisombululo malunga naso nasiphi na isicelo.Nangona kunjalo, ukwahluka kukwathetha ukuba kukho ithuba eliphezulu lokukhetha fan engalunganga ngaphandle kwesikhokelo esifanelekileyo.Eyona ngcebiso kukuphepha "umgaqo wesithupha" izigqibo, kwaye endaweni yoko ufumane uyilo lobuchwephesha oluhlangabezana neemfuno zeprojekthi yakho.
Iindidi zeeBlowers
Njengoko bekutshiwo ngaphambili, ii-blowers zisebenza ngomlinganiselo woxinzelelo we-1.11 ukuya kwi-1.2, nto leyo ebenza babephakathi phakathi kwefeni kunye necompressor.Banokuvelisa uxinzelelo oluphezulu kakhulu kunabalandeli, kwaye bayasebenza kwizicelo ze-vacuum zamashishini ezifuna uxinzelelo olubi.Iiblower zohlulwe zibe ziindidi ezimbini eziphambili: i-centrifugal kunye ne-positive displacement.
ii-centrifugal blowerszineemfano ezithile zomzimba kunye neempompo ze-centrifugal.Ngokuqhelekileyo zibandakanya inkqubo yegiya ukufezekisa isantya ngaphezulu kwe-10,000 rpm.I-centrifugal blowers ingaba nenqanaba elilodwa okanye ukwakhiwa kwamanqanaba amaninzi, apho i-design-stage-design inikezela ngokufanelekileyo okuphezulu, kodwa i-design yamanqanaba amaninzi inika uluhlu olubanzi lokuhamba komoya kwixinzelelo oluzinzileyo.
Njengabalandeli, ii-centrifugal blowers zinezicelo kwi-HVAC.Nangona kunjalo, ngenxa yoxinzelelo lwazo oluphezulu, zikwasetyenziselwa ukucoca izixhobo kunye nezicelo zeemoto.Umda wabo oyintloko kukuba ukuhamba komoya kuncipha ngokukhawuleza xa umqobo uphakamisa uxinzelelo, okwenza ukuba bangafaneleki kwizicelo ezinethuba eliphezulu lokuvala.
Iivutheli ezilungileyo zokufuduswaube nejiyometri yerotor eyenzelwe ukubamba iipokotho zomoya, ukuqhuba ukuhamba ngendlela ekujoliswe kuyo kuxinzelelo oluphezulu.Nangona zijikeleza ngesantya esisezantsi kunezivutheli zecentrifugal, zinokuvelisa uxinzelelo olwaneleyo lokuvuthela izinto ezivala inkqubo.Omnye umahluko obalulekileyo ngokhetho lwe-centrifugal kukuba ii-positive-blower blowers zihlala ziqhutywa ngamabhanti endaweni yeegiya.
Ukuqukumbela
Iifeni kunye nezivuthela zidla ngokuchazwa ngokusekwe kuxinzelelo kunye neemfuno zokuqukuqela komoya kwisicelo ngasinye, kunye neemeko ezithile zesiza ezifana nothuli kunye nobushushu.Nje ukuba uhlobo oluchanekileyo lwefeni okanye isivuthelo sichaziwe, ukusebenza kunokwandiswa ngeenkqubo zolawulo.Umzekelo,iidrive frequency frequency (VFD)inokunciphisa kakhulu ukusetyenziswa kombane kweefeni ezisebenza ngokuphindaphindiweyo.
