Mafani a Ceiling ndi High Volume Low Speed ​​(HVLS) mafanizimagwira ntchito zofanana popereka mpweya wozungulira ndi kuziziritsa, koma zimasiyana kwambiri malinga ndi kukula, mapangidwe, ndi machitidwe. Nazi kusiyana kwakukulu pakati pa ziwirizi:

1. Kukula ndi Kuphimba Dera:

Mafani a padenga: Amakhala kukula kwake kuyambira mainchesi 36 mpaka 56 ndipo amapangidwira malo okhalamo kapena ang'onoang'ono ogulitsa. Amayikidwa padenga ndipo amapereka mpweya wozungulira m'madera ochepa.

Mafani a HVLS: Okulirapo kwambiri, okhala ndi mainchesi kuyambira 7 mpaka 24 mapazi. Mafani a HVLS amapangidwira malo ogulitsa mafakitale ndi malonda okhala ndi denga lalitali, monga nyumba zosungiramo katundu, mafakitale, malo ochitira masewera olimbitsa thupi, ndi ma eyapoti. Amatha kuphimba malo okulirapo kwambiri ndi masamba awo akulu, omwe nthawi zambiri amakhala mpaka 20, 000 mapazi masikweya pa fan.

2.Kuthekera kwa Air Movement:

Mafani a padenga: Amagwira ntchito mothamanga kwambiri ndipo amapangidwa kuti azisuntha mpweya wocheperako bwino m'malo ochepa. Ndiwothandiza popanga kamphepo kayaziyazi komanso kuziziritsa anthu omwe ali pansi pawo.

Mafani a HVLS: Amagwira ntchito mothamanga kwambiri (nthawi zambiri pakati pa 1 mpaka 3 metres pa sekondi iliyonse) ndipo amakonzedwa kuti azisuntha mpweya wambiri pang'onopang'ono kudera lalikulu. Amachita bwino kwambiri popanga mpweya wokhazikika pamalo onse akulu, kulimbikitsa mpweya wabwino, ndikuletsa kutentha kwapakati.

3.Blade Design ndi Ntchito:

Mafani a padenga: Nthawi zambiri amakhala ndi masamba angapo (nthawi zambiri atatu kapena asanu) okhala ndi ngodya yotalikirapo. Amazungulira mothamanga kwambiri kuti apange mpweya wabwino.

Mafani a HVLS: Khalani ndi masamba ochepa, akulu (nthawi zambiri awiri mpaka sikisi) okhala ndi ngodya yozama kwambiri. Mapangidwewa amawathandiza kuti azisuntha mpweya bwino pa liwiro lochepa, kuchepetsa kugwiritsa ntchito mphamvu komanso phokoso.

4. Malo Okwera:

Mafani a denga: Amayikidwa pamwamba padenga ndipo amayikidwa pamtunda woyenera padenga lanyumba kapena lamalonda.

Mafani a HVLS: Amayikidwa padenga lalitali, nthawi zambiri kuyambira 15 mpaka 50 mapazi kapena kuposerapo pamwamba pa nthaka, kuti atengerepo mwayi wokulirapo kwawo ndikukulitsa kufalikira kwa mpweya.

5. Ntchito ndi Chilengedwe:

Mafani a padenga: Amagwiritsidwa ntchito kwambiri m'nyumba, m'maofesi, m'malo ogulitsa, ndi malo ang'onoang'ono amalonda pomwe malo ndi denga ndi lochepa.

Mafani a HVLS: Oyenera malo akuluakulu ogulitsa mafakitale, malonda, ndi mabungwe okhala ndi denga lalitali, monga malo osungiramo katundu, malo opangira zinthu, malo ogulitsa, malo ochitira masewera olimbitsa thupi, ma eyapoti, ndi nyumba zaulimi.

Cacikulu, pamene onse denga mafani ndiMafani a HVLSzimathandizira kuti mpweya uziyenda ndi kuziziritsa, mafani a HVLS amapangidwa makamaka kuti azigwira ntchito m'mafakitale ndipo amakonzedwa kuti azisuntha mpweya wambiri m'malo ambiri osagwiritsa ntchito mphamvu zochepa komanso phokoso lochepa.
