[TRNSYS-users] R: R: R: I: strange output for type 927

[Jeff Thornton]

Chiara, 

I don't have to look much farther than the data file. You have used a
comma for the decimal point and not '.' TRNSYS numbers must use the
decimal point. Please update your file and try again.

It looks like maybe the file you are using isn't normalized. Please send us your project and data files and we can verify.

So if you're seeing a large outlet temperature it means that you are giving the model a large inlet temperature. I suggest you review the TRACE command in TRNSYS and use it to figure out what may be going wrong with your simulation.

I have write the input file and i have modify the input schedule in trnsys, but ,when i run the simulation , i have strange value: for example my oulet load temperature= 1.6*10^8 and this is not normal. I have the same problem if i use the input file that trnsys give me as example with its default values.
