Kana zvasvika kunzvimbo huru dzemaindasitiri,Mafeni eHigh Volume Low Speed ​​(HVLS)ndiyo sarudzo inozivikanwa yekupa mhepo inoyerera zvakanaka uye inotonhodza. Chimwe chezvinhu zvakakosha pakuona kushanda kwefeni yeHVLS chiyero chayo cheCFM (Cubic Feet per Minute), icho chinoyera huwandu hwemhepo inogona kufambisa feni muminiti imwe chete. Kunzwisisa maverengero eCFM yefeni yeHVLS kwakakosha pakuona kuti yakakura zvakanaka panzvimbo yainoda kushandira.

Kuti uverenge CFM yefeni yeHVLS, unogona kushandisa fomura iyi:CFM = (Nzvimbo yenzvimbo x Kuchinja Kwemhepo Paawa) / 60. Nzvimbo yenzvimbo yachondiyo nzvimbo yese yenzvimbo ichapihwa feni, uyeshanduko yemhepo paawandiyo nhamba yaunoda kuti mhepo iri munzvimbo iyoyo itsiviwe zvachose nemhepo itsva muawa imwe chete. Kana wangowana mavalues ​​aya, unogona kuabatanidza mufomura kuti uone CFM inodiwa panzvimbo iyoyo.

VERENGA CFM YEMUFANANI

Kana zvasvika paApogee CFM, zvinoreva CFM yepamusoro iyo fan yeHVLS inogona kuwana nekumhanya kwayo kwepamusoro. Kukosha uku kwakakosha pakunzwisisa kugona kwefeni uye kuona kana ichikwanisa kusangana nezvinodiwa zvekufema nekutonhodza munzvimbo yakati. Zvakakosha kufunga nezveApogee CFM pakusarudza fan yeHVLS kuti uve nechokwadi chekuti inogona kupa mweya unodiwa kune chinangwa chayo.

Pamusoro pefomura yekuverenga CFM, zvakakoshawo kufunga nezvezvimwe zvinhu zvinogonakukanganisa mashandiroyefeni yeHVLS, sengedhizaini yebanga refeni, mashandiro emota, uye marongerwo enzvimbo yacho.Kuiswa zvakanaka kwefeni uye kuiswa kwayo panzvimbo kwayo kunogona kukanganisawo kugona kwayo kufambisa mhepo zvakanaka munzvimbo yese.

Mukupedzisa, kunzwisisa maitiro ekuverengaCFM ye fan yeHVLSZvakakosha pakuona kuti saizi yacho yakakodzera kushandiswa kwayo.Kufunga nezve Apogee CFM nezvimwe zvinhu zvinogona kukanganisa mashandiro efeni zvichabatsira pakusarudza feni yeHVLS yakakodzera kuti mhepo ifambe zvakanaka uye itonhore munzvimbo huru dzemaindasitiri.
