Dear TRNSYS users, I am using Type 99 in order to simulate a building with measured data. Someone of you is using Type 99 (T17) or Type 109 (T16)? I am wondering if the solar radiation data in the txt file should be in W/m2 (<mult> 1) or not. <var> IBEAM_H <col> 4 <interp> 0 <add> 0 <mult> ?? <samp> -1 !...to get radiation in W/m² What unit was considered when programming Type 99 ? After checking the type I saw a multiplication with 3.6 so I suppose the data in the external file should be in W/m2. If I consider the solar radiation on horizontal in W/m2 (<mult> 1) in the external file, when comparing data calculated by the Type 99 (output from Type 99 in kJ/h converted in W/m2) with the measured data (values in the external file in W/m2, at noon for example), the values are not identical. In conclusion, I want to check if Type 99 calculates and transfers the exact information given in the external file to the other types (Type56). Someone of you tried already this ?
