Kusankha fancha kutentha kwa fan nthawi zambiri kumakhala zovuta. Ngati mumagula fani yomwe ili ndi mphamvu zowonongetsa malo osungira ndi zonunkhira, mumayesetsa kukweza kwambiri moti palibe amene akufuna kuigwiritsa ntchito. Kumbali ina, ngati mumatsitsa mawu oposa-Boeing-747, mpaniyo sangakhale wamphamvu mokwanira kuti agwire ntchitoyo.
Zoonadi, malo abwino osambiramo amadzimadzi amakhalanso chete ndipo ali ndi malo okwanira.
Ndalama zimayenera kuganiziranso kuti zisagwiritsidwe ntchito, popeza sizingatheke kugula chifaniziro chokhazikika, chomwe chimapangitsa ndalama zokwana madola 800. Mudzapeza ambiri a mafani ndi chiwerengero chochepa chokha, muyeso womwe umagwiritsidwa ntchito phokoso lopsa, koma simungakhoze kupita pa zowerengera zosavuta za mwana yekha. Taonani zina mwazifukwa zomwe mungapange chisankho chodziwikiratu.
Kuyeza Maseŵero Akumveka kwa Achinyamata
Miyala, osati ma decibel, ndi mayunitsi a muyeso omwe amagwiritsidwa ntchito poyang'ana momwe kulimbika kwasambira kukulira. Miyala ndiyeso yeniyeni, yochokera kumalingaliro a maganizo a mphamvu ya mawu. Mafilimu amadzimadzi amodzi omwe amadzipangira okha amachokera ku 0,3 mwana kapena zocheperapo chifukwa cha zitsanzo zabwino kwambiri zomwe zimakhala zofanana ndi ana aamuna anayi kapena zina zowonjezera, zomwe zimatchedwa "chuma".
Kuyeza Kusuntha kwa Air
Mphamvu yogwira ntchito ya fan yotulutsa mpweya wa bafa imayesedwa mu cfm, kapena masentimita imodzi pamphindi. Uwu ndiwo mpweya wa mpweya umene mpweyawo umamwa kuchokera mu bafa mkati mwa mphindi imodzi. Mukhoza kuyang'ana pa anaes ndipo mutenge wotsekemera wotsika kwambiri koma osatsimikiziranso kuti fanasiyo ndiyiyeso wokwanira ku chipinda chanu chogona.
Wachiwiri ndi pamene kulingalira kwa cfm kumabwera. Monga lamulo lalikulu, kuchepetsa cfm kwa malo ena osambira ndi 50. Pambuyo pake, muyenera kukhala ndi 1 cfm pa malo amphindi. Mwachitsanzo, 10 × 10-foot-washrooms amafunika fan omwe adavotera pafupifupi 100 cfm.
Langizo: Kuti mutengere mwayi wanu wothandizira cfm, muyenera kupereka chakudya chokwanira, kapena "maonekedwe," mpweya mutasiya chitseko chokwanira mokwanira pamene fanaku ikutha.
Achifwamba samangoyamwa mpweya woipa ; Amapanga mpweya wabwino pogwiritsa ntchito mpweya wabwino nthawi yomweyo. Ngati mukusowa mpweya wozizira, sungagwire bwino ntchito yake.
Ndi Dziko Lophatikiza
Tchati chotsatira pogwiritsira ntchito ana ndi data cfm kuchokera m'mabuku ochepa otchuka amasonyeza mmene mwana amakula pamene cfm akuwonjezeka. Mawonekedwe ambiri <0.3 okhawo amasunthanso 80 cfm kapena osachepera, pomwe ambiri a ma 1.0 omwe ali ndi mawonekedwe amodzi amasuntha 140 cfm kapena ochulukirapo. Koma sizinali zophweka. Monga momwe tchati chikusonyezera, ndiyambiri ya kayendedwe ka zig-zag kumtunda, ndi zochepa zomwe zimasuntha mpweya wambiri ndi phokoso lochepa.
Lowani Single Sone Rating (SSR), chiwerengero cha miyendo ya cubic pamphindi yomwe inachotsedwa payekha (sones / cfm). Nambala zapamwamba za SSR zili bwino. SSR ndi yofunika chifukwa imayimitsa payokha-cf-cfm "ndalama." Ndibwino kuti mukhale ndi fanesi yomwe imatulutsa mpweya waukulu phokoso lochepa, ngati galimoto yomwe ikupita patali pang'ono.
Monga chitsanzo chochuluka, ganizirani Broan Model 688, yomwe imakhala yotchuka kwambiri kapena yosungirako ndalama zomwe mungathe kuziyika mu nyumba ya nyumba kapena malo ogulitsa. Pa phokoso la phokoso la ana 4.0 omwe amamveka phokoso, limatulutsa 50 cfm. SSR yake ndi 12.5, yochepera kuposa wina aliyense yemwe timamufunsa.

Nkhani Zofunika, Nawonso
Chinthu chinanso chofunika kuganizira ndi Kuwerengera Koyendetsera Mtengo, zomwe zimagwiritsa ntchito mtengo wamtengo wapatali wa fancha (SSR / mtengo) kukuthandizani kuwona kuchuluka kwa kayendetsedwe ka mpweya pamodzi ndi ana aang'ono omwe mukupeza pa dola. Zaka Zapamwamba Kuwerengera Kusintha kwa Nambala kuli bwino.
Mwachitsanzo, Broan 688 yomwe inatchulidwa kale imalandira ndalama zokonzera ndalama za 0.9. Komabe ngati mukufunafuna zotsika mtengo, zoyera komanso zophweka, Broan 688 ingawoneke bwino. Pa $ 14 okha, nthawi zambiri ndi zotsika mtengo kuposa mafani oyambirira mndandanda wathu pansipa. Kuti muyang'ane pa njira ina, mukhoza kuyika mafani mu malo okwana 5 mpaka 10 pa mtengo wa chipangizo chimodzi chapamwamba (osati kuwerengera mtengo wazitsulo, ndithudi).
Otsitsimula Otetezera Mafilimu Oyeretsa Anavotera
Nazi atatu mafani abwino pamsika. Pali zowonjezera mafani omwe ali ndi mafananidwe ofanana ndi amodzi, koma kuyang'anitsitsa ndi ochepa kumakuthandizani kumvetsa momwe mungasankhire munthu wokhala ndi chimbudzi chomwe chimakwaniritsa zosowa zanu za mpweya komanso bajeti yanu.
1. Panasonic FV-15VQ5 WhisperCeiling
- CFM : 150
- Mitundu : 0.3
