Re: [TRNSYS-users] problem with weather file .109

Faustine,
  If you are using Trnsys17, it is highly recommended that you change from using Type109 to using Type99. Type99 is the "user format" mode from Type109. Type109's ability to read standard format weather files (such as TMY2/Meteonorm) has been replaced by Type15.

  Whether you are using Type109 in Trnsys16 or Type99 in Trnsys17, there are a number of lines at the top of the data file being read that dictate which column in the file contains which pieces of the data. Look at the example data files:

..\Trnsys16\Examples\Data Files\Type109-UserFormat.109
..\Trnsys17\Examples\Data Files\Type99-UserFormat.99

The line:

<var>    TAMB    <col>    3  <interp> 2  <add>  0  <mult>  1     <samp>   0    !...to get °C

dicates that the ambient temperature data is in column 3, that it should be interpolated, and that the values are already in °C (and therefore do not need to be converted).

Kind regards,
 David

Dear all,
 
I have a big problem with my weather files. I'm trying to compare a meteonorm file with a real weather file for the same place.
I'm using for my real case a type 109 using the Perez model.
To compare outside temperature I decided to plout out my two files with a type 65.
 
I get the following problem: My ouside temperature plotted out (from my type 109) does not correspond to the temperature of the column defined as TAMB ?
 
I need ur help please...How could you explaine this problem? Where does the error come from? I have no idea about it!
 
Thaks a lot
