Xa kuziwa kwiindawo ezinkulu zemizi-mveliso,Abalandeli beVolume High Low Speed ​​(HVLS).lukhetho oludumileyo lokubonelela ngokujikeleza komoya okusebenzayo kunye nokupholisa. Enye yezinto eziphambili ekumiseleni ukusebenza kwe-fan ye-HVLS yi-CFM yayo (i-Cubic Feet ngomzuzu), elinganisa umthamo womoya umqhubi onokuhamba ngomzuzu. Ukuqonda indlela yokubala i-CFM ye-fan ye-HVLS ibalulekile ekuqinisekiseni ukuba ilinganiswe ngokufanelekileyo kwindawo ekujoliswe kuyo ukukhonza.

Ukubala i-CFM ye-fan ye-HVLS, ungasebenzisa ifomula:CFM = (Ummandla wesithuba x Utshintsho loMoya ngeyure) / 60. Indawo yendawoyimbuyekezo yesikwere iyonke yommandla oza kusetyenziswa yifeni, kwayeutshintsho lomoya ngeyurelinani lamaxesha ofuna ukuba umoya okuloo ndawo utshintshwe ngokupheleleyo ngomoya omtsha ngeyure. Wakuba unala maxabiso, unokuzifakela kwifomula ukumisela i-CFM efunekayo yesithuba.

BALA I-CFM YEFAN

Xa kuziwa kwi-Apogee CFM, ibhekisa kwi-CFM ephezulu enokufikelela kwi-HVLS fan ngesantya esiphezulu. Eli xabiso libalulekile ekuqondeni izakhono zefeni kunye nokugqiba ukuba ingakwazi ukuhlangabezana ngokufanelekileyo neemfuno zokungena komoya kunye nokupholisa kwendawo ethile. Kubalulekile ukuqwalasela i-Apogee CFM xa ukhetha i-fan ye-HVLS ukuqinisekisa ukuba inokuhambisa i-airflow efunekayo kwisicelo esicetywayo.

Ukongeza kwifomula yokubala i-CFM, kubalulekile ukuqwalasela ezinye izinto ezinokuthiifuthe kumsebenziye fan HVLS, ezifanauyilo lweblade yefeni, ukusebenza kakuhle kwemoto, kunye noyilo lwendawo.Ukufakwa ngokufanelekileyo kunye nokubekwa kwefeni kunokuchaphazela amandla ayo okuhambisa umoya ngokufanelekileyo kuyo yonke indawo.

Ukuqukumbela, ukuqonda indlela yokubala iI-CFM ye-HVLS fanibalulekile ekuqinisekiseni ukuba ilinganiswe ngokufanelekileyo kwisicelo esicetywayo.Ukuqwalasela i-Apogee CFM kunye nezinye izinto ezinokuchaphazela ukusebenza kwefeni kuya kunceda ekukhetheni i-fan ye-HVLS efanelekileyo yokusasazwa komoya kunye nokupholisa kwiindawo ezinkulu zemizi-mveliso.
