Chii chinonzi Fan Filter Unit?
Chiyuniti chefirita yefeni kana FFU chakakosha selaminar flow diffuser ine fan nemota yakabatanidzwa. Fan nemota zviripo kuti zvikunde kumanikidzwa kwe HEPA kana ULPA filter yakaiswa mukati. Izvi zvinobatsira mukugadzirisa mashandiro apo simba refeni riripo kubva kuair handler harina kukwana kukunda kudonha kwekumanikidzwa kwefirita. FFU dzakakodzera kuvaka kutsva uko mwero wekuchinja kwemhepo wakakwira uye nzvimbo dzakachena zvakanyanya zvinodiwa. Izvi zvinosanganisira mashandisirwo akadai sema pharmacies emuzvipatara, nzvimbo dzemishonga dzakasanganiswa uye micro electronics kana zvimwe zvivakwa zvekugadzira zvine hungwaru. FFU inogona zvakare kushandiswa kusimudzira ISO classification yemakamuri nekukurumidza uye zviri nyore nekuwedzera ma fan filter units padenga. Zvakajairika kuti ISO plus 1 kusvika ku5 makamuri akachena kuti denga rese rifukidzwe nema fan filter units nekushandisa FFU panzvimbo pe central air handler kupa shanduko dzemhepo dzinodiwa. Saizi yeair handler inogona kuderedzwa zvakanyanya. Pamusoro pezvo ne arrange yakawanda yeFFU, kukundikana kweFFU imwe chete hakukanganisi mashandiro esystem yese.
Kugadzira Sisitimu:
Dhizaini yakajairika yesystem yekamuri yakachena ndeyekushandisa negative pressure common plenum apo FFU inodhonza mhepo yakakomberedza kubva mukudzoka kwakajairika, uye inosanganiswa nemamiriro ezvinhu inogadzira mhepo kubva kuchikamu chekubata mhepo. Chimwe chinhu chikuru che negative pressure common plenum FFU system ndechekuti inobvisa njodzi dzekuti zvinhu zvinosvibisa zvinobva padenga reimba zvikaiswa munzvimbo yakachena iri pasi. Izvi zvinoita kuti sisitimu yedenga isingadhuri uye yakaoma ishandiswe. Pamwe nekuisa mayuniti mashoma.
Saizi Yakajairika:
FFU inogona kuburitswa zvakananga kubva pamudziyo wemhepo kana mudziyo weterminal. Izvi zvakanaka pakugadzirisa nzvimbo yacho apo nzvimbo yacho iri kuvandudzwa kubva pakuisa ma laminar asiri ekusefa kuenda kuFFU ine ma duct. FFU inowanzo kuwanikwa muhukuru hutatu, 2ft x 2 ft, 2ft x 3 ft, 2 ft x 4ft uye yakagadzirirwa kukwana mugridi yedenga yakasungirirwa. FFU inowanzo saizi ye90 kusvika 100 FPM. Kune hukuru hunozivikanwa hwe2ft x 2 ft izvi zvakaenzana ne480 CFM yemuenzaniso wefirita unotsiviwa nekamuri. Kuchinja mafirita chikamu chakakosha chekugadzirisa nguva dzose.
Mafashoni Esefa:
Kune masitayera maviri akasiyana eFFU anobatsira kuchinja mafirita nenzira dzakasiyana. Mafirita anotsiviwa neparutivi pekamuri anobvumira kupinda mufirita kubva kurutivi rwekamuri pasina kukanganisa kuvimbika kwesiringi. Mayuniti anobviswa padivi pekamuri ane mupendero webanga wakabatanidzwa unopinda muchisimbiso chegel chefirita kuitira kuti pave nechokwadi chekuti hapana kubuda kwemvura. Mayuniti anotsiviwa nepadenga rebhenji anofanira kubviswa padenga kuti atsiviwe nefirita. Mafirita anotsiviwa neparutivi pebhenji ane nzvimbo yefirita yakawanda ye25% iyo inobvumira mwero wemhepo wakakwira.
Sarudzo dzeMotokari:
Imwe sarudzo yekutarisa pakusarudza fan unit imhando yemota inoshandiswa. PSC kana AC induction type motors ndiyo sarudzo inodhura zvishoma. ECM kana brushless DC motors ndiyo sarudzo yepamusoro yekushanda nema micro processors ari mukati ayo anovandudza mashandiro emota uye anobvumira motor programming. Paunenge uchishandisa ECM pane mapurogiramu maviri emota aripo. Chekutanga i constant flow. Constant flow yemota inochengetedza mweya uchifamba ne fan filter unit isina static pressure sezvo filter ichitakura. Izvi zvakanaka kune negative pressure common plenum designs. Chechipiri motor program i constant torque. Constant torque motor program inochengetedza torque iyoyo kana rotational force yemota isina static pressure sezvo filter ichitakura. Kuti mhepo irambe ichiyerera ne fan filter unit ne constant torque program, upstream pressure independent terminal kana venturi valve inodiwa. FFU ine constant flow program haifanirwe kudhonzwa zvakananga kune upstream pressure independent terminal device, sezvo izvi zvichiita kuti zvishandiso zvese zviri smart zvirwire kudzora uye zvinogona kutungamira kumhepo inoyerera uye kusashanda zvakanaka.
Sarudzo dzeMavhiri:
Pamusoro pesarudzo dzemota, kunewo sarudzo mbiri dzemavhiri. Mavhiri akakombama emberi ndiwo akajairika uye anoenderana neEC motor uye constant flow program. Mavhiri akakombama ekumashure kunyangwe asingaenderane neconstant flow motor program isarudzo inoshandisa simba shoma.
MaFFU akawedzera mukurumbira zvishoma nezvishoma nekuda kwekugadzirwa kwawo kusingashandise simba zvakanyanya uye njodzi yekudzikira kwekushanda kwenguva pfupi nekuda kwehurongwa hwekubata mhepo hwakaderedzwa. Dhizaini yemamodular emaFFU systems inobvumira shanduko dziri nyore uye nekukurumidza muISO classifications dzemakamuri ekuchenesa. MaFFU ane akawanda maficha anobatsira uye sarudzo dzinobvumira kugadzirisa system zvakakwana uye sarudzo dzakazara dzekudzora dzinobvumira Start up nekukurumidza uye commission, uye kutonga kwakazara uye kutarisa system panguva yekushanda.
