Re: Kev suav teeb pom kev zoo thiab RCR (Chav Kab Ntsig Piv Txwv)
- Room Cavity Ratio (rau cov duab tsis xwm yeem chav ) = (2,5x Room Cavity Qhov tob x Ib puag ncig) ÷ Cheeb Tsam hauv Square Taw.
- Luas = Length + Length + Width = 2 * Length + 2 * Dav = 2 (Length + Width)
Cov lus nug tseem yog, dab tsi yog chav kab noj hniav sib piv?
Siv nyob rau hauv lub tsev teeb pom kev zoo xam, lub Chav Cavity Piv (RCR) ntsuas qhov ua tau zoo li cas a chav lossis lwm qhov chaw sab hauv yog siv lub teeb los ntawm cov khoom siv uas muaj nyob ntawd. [Tseem muaj Zonal Cavities thiab Ceiling Cavities, tab sis feem ntau siv yog cov Chav Cavity.
Tom qab ntawd, lo lus nug yog, koj ua li cas xam cov teeb theem hauv ib chav? Nov yog cov ntsiab lus thiab lub laij lej los pab koj.
- Siv lub teeb rooj kom paub seb muaj pes tsawg lux lossis footcandles koj xav tau.
- Laij cov lumens uas koj xav tau. Muab thaj tsam hauv thaj tsam ib square metres los ntawm qhov zoo nkauj, lossis thaj tsam hauv square feet los ntawm tus hneev taw.
- ua haujlwm seb koj xav tau pes tsawg qhov muag teev.
Tib neeg kuj nug, koj ua li cas xam qab nthab kab noj hniav piv?
Kauj Ruam: Chav kab noj hniav ratio = 2.9; qab nthab kab noj hniav piv = 0.0 (rov qab teeb); pem teb kab noj hniav piv = 1.2 (piv txwv li rau 20 x 30 x 3' qhov tob) Siv tau qab nthab reflectance = ua. 80; zoo hauv pem teb reflectance =.
Lumen sawv rau dab tsi?
Lumens = Lub teeb tso zis. Hauv cov ntsiab lus yooj yim, Lumens (los ntawm lm) yog ib qho kev ntsuas ntawm tag nrho cov teeb pom kev zoo (rau tib neeg lub qhov muag) los ntawm lub teeb lossis lub teeb ci. Qhov siab dua lub lumen ntsuas qhov "ci dua" lub teeb yuav tshwm.

Yuav ua li cas koj xam qhov nam piv ntawm ib lub log tsheb?
ASPECT RATIO. Feem ntau hu ua profile lossis series, qhov sib piv ntawm lub log tsheb yog txiav txim siab los ntawm kev faib lub log tsheb qhov siab los ntawm nws cov seem dav thaum lub log tsheb yog: inflated mus rau siab tshaj plaws huab cua siab, mounted rau qhov kev pom zoo ntsuas rim, thiab tsis muaj load
Koj xam xam lux thiab lumens li cas?
1 lx = 1 lm/mm2. 1 Lumen ib Square Meter: Lumen ib square meter sib npaug rau Lux (SI unit). Kev ntsuas tus naj npawb ntawm Lumens poob ntawm thaj tsam ntawm ib square meter, lub ntsiab lus ntawm Lux
Koj xam xam qhov nruab nrab qhov pom kev li cas?
Qhov nruab nrab qhov ci ntsa iab a = ntev ntawm chav nyob hauv meters; b = dav ntawm cheeb tsam hauv meters; h = nrug deb ntawm qhov nruab nrab ntawm cov teeb pom kev zoo thiab lub dav hlau uas koj yuav tsum ntsuas lub teeb pom kev zoo (piv txwv li qhov siab ntawm cov teeb pom kev zoo 2.80 m, qhov chaw ua haujlwm ntawm qhov siab 0.8 m, h = 2.80 txog 0.8 = 2)
Koj xam xam qhov chaw txav chaw nyob li cas?
Txhawm rau txiav txim siab qhov hloov chaw ntawm qhov chaw nres nkoj, peb tsuas yog muab thaj tsam hla ntu los ntawm qhov ntev ntawm qhov chaw nres nkoj (uas peb tau txiav txim siab ua 12 "hauv qhov piv txwv no.) Displaced Volume = 9.61625 X 12 = 115.395 cu.in
Koj xam xam pib lub zog ntawm lub cav li cas?
Raws li koj pom qhov sib npaug torque yog cov khoom ntawm lub zog thiab qhov kev ncua deb ntawm lub zog thiab qhov chaw ntawm kev sib hloov. Piv txwv li, yog tias koj xav tuav lub zog ua haujlwm ntawm qhov kawg ntawm rub, T = F x r
