Mafilimu otulutsa mafilimu, kapena kutulutsa mafilimu, amachita zinthu ziwiri zofunika: amachotsa mpweya wotentha, komanso amachotsa zonunkhira. Kutentha, mpweya wozizira kumapangitsa kukula kwa nkhungu, ndipo zonunkhira zimapangitsa kuti zisakhale zosasangalatsa. Zizindikiro za kumanga zimapangitsa anthu kuti azitsuka mumasamba onse atsopano ndi osinthidwa, ndipo ndi ofunika kwambiri muzipinda zam'mbuyo zakale, ngakhale zomwe zili ndi mawindo a mpweya wabwino (zomwe sizing'ono kwambiri m'nyengo yachisanu ndipo sizichotsa chinyezi komanso mafani).
Koma kukhazikitsa wofooka, wotsimikiziridwa ndiwotchi sizingawathandize, ngakhale wotchiyo akukwaniritsa zofunikirazo. Gwiritsani ntchito mfundo zotsatirazi kuti muyambe kulondola.
Mafilimu Omwe Amakonda
Mafilimu otulutsa mpweya amayerekeza ndi kuchuluka kwa mpweya omwe amatha kusuntha, amayeza mamitala imodzi pamphindi, kapena cfm . Zomwe zimapangidwira zimagwiritsidwa ntchito kuzipinda zodyeramo zomwe zili ndi mamita 100 kapena osachepera. Ulamuliro wa thumbu ndikuti mukufunikira osachepera 1 cfm pa malo osanjikizira. Kuti mudziwe tsatanetsatane wa malo anu osambira, wonjezerani nthawi yaitali m'lifupi. Mwachitsanzo, ngati bafa yanu ili mamita 6 m'litali ndi mamita 9 m'litali, mapepala ake oposa masentimita ndi 54. Chifukwa chake, ayenera kukhala ndi fanasi omwe adavotera 54 cfm. Koma musanayambe kugula, pali zinthu zingapo zomwe muyenera kuziganizira. Choyamba, ndibwino kuti muzitha kupitirira mpweya. Mu chitsanzo cha pamwambapa, muyenera kupeza 60 cfm fan payeso yabwino. Chachiwiri, ngati chipinda chanu chogona chimakhala ndi jekeseni kapena zipinda zogawanika kapena zidutswa zochepa, mungathe kufuna zowonjezera (onani m'munsimu).
Ndipo chachitatu, osachepera amavomereza kukula kwa firimu ndi 50 cfm, kotero ngati chipinda chanu chogona ndi, nkuti, makilomita 42 okha, mukufunikirabe 50 fm fan.
Kufuna Malo Amkati Osambira
Pazipinda zapakati pa mamita 100, mamita otopa amatha kukula ndi chiwerengero cha zipinda mu chipinda. Kuti muwerenge pogwiritsira ntchito fomuyi, onjezerani zofunikira za cfm zofunikira pa zonsezi:
- Bhati: 50 cfm
- Mtsuko woyendetsedwa: 100 cfm
- Kusamba: 50 cfm
- Chophimba: 50 cfm
Choncho, kusamba ndi chimbudzi mu bafa kudzafuna firii 100 cfm, pamene chipinda chogona ndi jekeseni, chimbudzi ndi madzi akufunikira 200 cfm fan.
Chiwerengero china chothandizira pazipinda zazikuluzikulu zokhala ndi mapiri otalika (kuposa mamita asanu ndi atatu): Lonjezerani mapepala apamwamba ndi kutalika kwa denga, gawani ndi 60 (mphindi imodzi mu ora limodzi), ndikuchulukitseni ndi 8 (maulendo ovomerezeka a mpweya pa ola limodzi). Mwachitsanzo, pa chipinda chokhala ndi mamita 120 ndipo chili ndi denga la mapazi 10:
120 x 10 = 1,200
1,200 / 60 = 20
20 x 8 = 160 cfm
Kodi Mukusowa Woposera Mmodzi?
Ngati malo anu osambira ali ndi chimbudzi chosungira kapena malo osambira, ndibwino kuti mupange firiji yodziyeretsa yeniyeniyo. Ngati danga liri laling'ono, fani la 50 cfm liyenera kukhala lokwanira. Apo ayi, gwiritsani ntchito kuwerengera koyenera malinga ndi kukula kwa chipinda. Wopanga wosiyana amathandiza kwambiri pamene malo omwe ali mkati ali ndi khomo. Ingokumbukirani kuti fanaku akufunikira mpweya wa mpweya kuti achite ntchito yake. Ngati chitseko chatsekedwa ndipo palibe phokoso pansi pa chitseko, mphunzitsiyo adzafa ndi "mpweya" mpweya ndipo adzachita bwino. Phokoso liyenera kukhala laling'ono la 5/8 masentimita, kapena mutuluke pakhomo pakhomo pamene fanaku ikuyenda.
