Kodi Fan Filter Unit ndi chiyani?
Fanizo la zosefera kapena FFU ndiyofunikira cholumikizira cholumikizira chalaminar chokhala ndi fani yophatikizika ndi mota.Zokupizira ndi mota zilipo kuti zigonjetse kupanikizika kwapakatikati kwa HEPA kapena ULPA fyuluta.Izi ndizopindulitsa pamapulogalamu obwezeretsanso pomwe mphamvu za fan zomwe zilipo kuchokera ku chothandizira mpweya ndizosakwanira kuthana ndi kutsika kwa fyuluta.FFU ndi oyenera kumanga kwatsopano komwe kukufunika kusintha kwa mpweya komanso malo aukhondo kwambiri.Izi zikuphatikiza ntchito monga malo ogulitsa mankhwala azipatala, malo ophatikizira mankhwala ndi zida zamagetsi zazing'ono kapena malo ena opangira zinthu.FFU itha kugwiritsidwanso ntchito kukweza mwachangu komanso mosavuta gulu la ISO lazipinda pongowonjezera zosefera za fan padenga.Ndizofala kuti zipinda zoyera za ISO kuphatikiza 1 mpaka 5 kuti denga lonse likhale lophimbidwa ndi zosefera za fan pogwiritsa ntchito FFU m'malo mwa chowongolera mpweya chapakati kuti apereke kusintha kofunikira kwa mpweya.Kukula kwa chowongolera mpweya kumatha kuchepetsedwa kwambiri.Kuphatikiza apo ndi gulu lalikulu la FFU kulephera kwa FFU imodzi sikusokoneza magwiridwe antchito a dongosolo lonse.
Kupanga Kwadongosolo:
Kapangidwe ka zipinda zoyera ndikugwiritsa ntchito mphamvu yoyipa yomwe FFU imakoka mpweya wozungulira kuchokera kumayendedwe wamba, ndipo imasakanizidwa ndi momwe zimapangidwira mpweya kuchokera kugawo loyendetsa mpweya.Ubwino umodzi waukulu wa kukakamiza koyipa kwa plenum FFU system ndikuti kumachotsa kuopsa kwa zonyansa zomwe zimasamuka kuchokera padenga kupita kumalo oyera omwe ali pansipa.Izi zimapangitsa kuti pakhale denga lotsika mtengo komanso lovuta kugwiritsa ntchito.Kapenanso yoyika ndi mayunitsi ochepa.
Kukula Wokhazikika:
FFU imatha kuthamangitsidwa mwachindunji kuchokera ku chothandizira mpweya kapena chipangizo cholumikizira.Izi ndi zabwino kwa retrofit ntchito kumene danga akwezedwa kuchokera non-sefa laminars kuti ducted FFU.FFU imapezeka mu makulidwe atatu, 2ft x 2 ft, 2ft x 3 ft, 2 ft x 4ft ndipo amapangidwa kuti agwirizane ndi gridi yoyimitsidwa yapadenga.FFU nthawi zambiri imakhala ndi kukula kwa 90 mpaka 100 FPM.Kwa kukula kodziwika bwino kwa 2ft × 2 ft izi zikufanana ndi 480 CFM pagawo la chipinda chosinthira fyuluta.Kusintha kwa zosefera ndi gawo lofunikira pakukonza pafupipafupi.
Masitayelo Osefera:
Pali mitundu iwiri ya FFU yomwe imathandizira kusintha kwa fyuluta m'njira zosiyanasiyana.Zosefera za m'zipinda zosinthika zimalola mwayi wofikira zosefera kuchokera kumbali yachipinda popanda kusokoneza kukhulupirika kwa denga.Zipinda zochotseka m'zipinda zimakhala ndi mpeni wophatikizika womwe umalowa mu sefa ya gel osindikizira kuti atsimikizire kulumikizidwa kwaulere.Benchi pamwamba mayunitsi replaceable ayenera kuchotsedwa padenga kuti m'malo fyuluta.Zosefera zapamwamba zosinthika za benchi zimakhala ndi 25% zosefera zambiri zomwe zimalola kuti mpweya uziyenda kwambiri.
Zosankha zamagalimoto:
Njira inanso yomwe mungayang'ane posankha gawo la fan ndi mtundu wa mota yomwe imagwiritsidwa ntchito.PSC kapena AC induction type motors ndiye njira yotsika mtengo kwambiri.ECM kapena brushless DC motors ndiye njira yabwino kwambiri yokhala ndi ma processor ang'onoang'ono omwe amawongolera magwiridwe antchito agalimoto ndikuloleza pulogalamu yamagalimoto.Mukamagwiritsa ntchito ECM pali mapulogalamu awiri omwe amapezeka.Choyamba ndi kuyenda kosalekeza.Kuyenda kosalekeza kwa pulogalamu yamagalimoto kumapangitsa kuti mpweya uziyenda kudzera pagawo lazosefera zosasunthika mosasunthika pomwe fyulutayo imanyamula.Izi ndizoyenera kukakamiza kukakamiza kophatikizana kwa plenum.Pulogalamu yachiwiri yamagalimoto ndi torque yokhazikika.Pulogalamu yamoto ya torque yosalekeza imasunga torque imeneyo kapena mphamvu yozungulira ya mota osadalira kukakamiza kwa static pomwe fyulutayo imanyamula.Kuti mpweya usasunthike kudzera pagawo losefera la fan lomwe lili ndi pulogalamu ya torque yosalekeza, cholumikizira cham'mwamba chodziyimira pawokha kapena venturi valve chimafunika.FFU yokhala ndi pulogalamu yoyenda mosalekeza sayenera kuyendetsedwa mwachindunji ku chipangizo chapamwamba chopanda mphamvu, chifukwa izi zimapangitsa zida zonse zanzeru kumenyera kuwongolera ndipo zimatha kupangitsa kuti mpweya uziyenda bwino komanso kusagwira bwino ntchito.
Zosankha zamagudumu:
Kuphatikiza pa zosankha zamagalimoto palinso njira ziwiri zamagudumu.Mawilo okhotakhota Patsogolo ndi njira yokhazikika ndipo imagwirizana ndi EC mota ndi pulogalamu yoyenda mosalekeza.Mawilo okhotakhota kumbuyo ngakhale kuti sagwirizana ndi pulogalamu yamoto yothamanga nthawi zonse ndi njira yowonjezera mphamvu.
Ma FFU achulukirachulukira kutchuka chifukwa cha kapangidwe kawo kogwiritsa ntchito mphamvu komanso kuchepetsa chiwopsezo cha nthawi yopumira chifukwa cha kayendetsedwe ka mpweya.Mapangidwe amtundu wa FFU amalola kusintha kwachangu komanso kosavuta kumagulu a ISO azipinda zoyeretsa.FFU's ili ndi zinthu zambiri zothandiza komanso zosankha zomwe zimalola kuti makinawo azisintha komanso zosankha zambiri zowongolera zomwe zimaloleza Kuyambitsa ndi kutumiza mwachangu, ndikuwongolera ndi kuyang'anira dongosolo panthawi yogwira ntchito.
