<DIV>Dear TRNSYS users, I have some questions for you :</DIV>
<DIV> </DIV>
<DIV>1°) I try to use the type 67 with the type 56a (Multizone Building).</DIV>
<DIV> But, it seems to me that I <STRONG><U>must</U></STRONG> used the type 34 in complement.</DIV>
<DIV> [Output 11 of type 34 (Fraction of solar shading) ---> Input of type 56a (created by me to used in Input of External Shading Factor)]</DIV>
<DIV> because the type 67 gives me 2 outputs (among 11) :</DIV>
<DIV>
<DIV> [Output 7 of type 67 (Fraction of beam visible on horizontal for mask) ---> ?</DIV>
<DIV> [Output 9 of type 67 (Fraction of diffuse visible on horizontal for mask) ---> ?</DIV>
<DIV> that I don't know used with the type 56a directly.</DIV>
<DIV> </DIV>
<DIV>2°) I have read the files of the forum and I try the solution proposed by Diego (Wed Oct 26 2005) to Amelie Mariller</DIV>
<DIV> who recommend to use two type 68 (one horizontal and one vertical) with each type 34.</DIV>
<DIV> So, I have created two files in ".dat" :</DIV>
<DIV> the first with a slope of 0°</DIV>
<DIV> and the second with a slope of 90°.</DIV>
<DIV> The two files dividing the same others informations.</DIV>
<DIV> But I have the message : Error "Unable to read mask file, please check file syntax and format." when I launch the calculs.</DIV>
<DIV> </DIV>
<DIV>3°) So, I use only one type 68 with one type 34 :</DIV>
<DIV> </DIV>
<DIV> [Output 3 of type 67 Shaded beam radiation for surface ---> Input 5 of type 34 (Beam radiation on surface)]</DIV>
<DIV> [Output 10 of type 67 Shaded diffuse radiation on horizontal for mask ---> Input 4 of type 34 (Horizontal diffuse radiation)]</DIV>
<DIV> [Output 11 of type 67 Shaded total radiation on horizontal for mask ---> Input 3 of type 34 (Total horizontal radiation)]</DIV>
<DIV> </DIV>
<DIV> Parameter 1 of type 34 Upstream component mode = 1 and not 0</DIV>
<DIV> </DIV>
<DIV> In more, I use two Equations :</DIV>
<DIV> </DIV>
<DIV> a) Equation 1 :</DIV>
<DIV> </DIV>
<DIV> Sky diffuse radiation on titled surface i (Output of type 109)</DIV>
<DIV> +</DIV>
<DIV> Groung reflected diffuse radiation on titled surface i (Output of type 109)</DIV>
<DIV> =</DIV>
<DIV> Diffuse radiation for opening (Input 6 of type 67)</DIV>
<DIV> </DIV>
<DIV>
<DIV> b) Equation 2 :</DIV>
<DIV> </DIV>
<DIV> Sky diffuse radiation on horizontal</DIV>
<DIV> +</DIV>
<DIV> Groung reflected diffuse radiation on horizontal</DIV>
<DIV> =</DIV>
<DIV> Diffuse radiation on horizontal (Input 4 of type 69b and Input 4 of type 67)</DIV>
<DIV> </DIV>
<DIV> After simulation, I have controlled the five View factor (Outputs 6,7,8,9,10 of type 34) by Online plotter (type 65d)</DIV>
<DIV> and I'm surprise because the sum is not equal to 1 !</DIV>
<DIV> But if I change : </DIV>
<DIV> Parameter 1 of type 34 Upstream component mode = 0 and not 1</DIV>
<DIV> the sum is correct.</DIV>
<DIV> </DIV>
