Re: [TRNSYS-users] Simulation with data that repeat ciclically

[David BRADLEY <d.bradley@tess-inc.com>]

Ivan,
  Angel makes a very good point about the radiation processor. Type9 will of course rewind itself as soon as it gets to the end of the file. However, the sun position as computed by the Type16 radiation processor will keep progressing with simulation time. One thing that you could do is to run a 1-day simulation and pre-process all of the solar radiation data (in other words use a Type9 to read in the raw data and a Type16 to process the solar. Then use a Type25 (printer) to create an output file that contains not only the temperature, humidity, pressure etc directly from your original data file but also the processed solar radiation for the surfaces that are of interest. In your second simulation, you would read in the output file from the first simulation using a Type9; you could just have a single day of data in the file and the file would rewind at the end of each day.
Best,
 David

Dear trnsys users:

 

I need to simulate a building with actual climate data during one day (for example 1st of February) that repeats cyclically (supongamos 10 veces). After reading the documentation, I did not find any way to do it automatically or in easy way.

For this reason I have thought of getting the data set of one day from the tm2 file (24 hours) and create a file with these climatic data repeated  ten times (240 hours). Then I will use the type 9 to read them.

 

Another suggestion?

 

Thanks a lot in advance.

Kind regards
