Re: [TRNSYS-users] Error and Fan coil, radiator model

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

Muhammad,
  The excel file has most of the data that you need in it in rows 9-17. The independent variables required by Type938's data file (the lines across the top of the file) are the temperatures in column B and the dependent variable values are in column C or D. The map given in the data file is not complete (ie not all combinations are given). What I would recommend you do is to normalize the data in your excel spreadsheet (divide all of the power values by the power at rated conditions) then overlay that normalized data on a plot of the example Type938 data.  You should find that your data, once normalized, fits pretty well with the example normalized data, in which case you can use the default data file.
Kind regards,
 David

Hi David,

Thanks for your kind reply. I fixed my errors. Now the problem is I can not understand how to make external file for my heat pump. I am using type 938. The data which I get from manufacture is in attached file, Which is not as it was written as default in type 938. I am attaching manufacture data and Type 938 data file.

 

I hope to hearing from you soon.

 

Kindest Regards

Muhammad,
  In order to run your simulation, I would need the data files for the Type534 tank and for the Type938 heat pump. The *.lst and *.log files contain information as to the cause of the error. As for a radiator and a fancoil model, both are available in the TESS HVAC Library for Trnsys17.
Kind regards,
 David

Hi,

I have simulated a Solar assisted heat pump system. I am getting some errors, could not understand what these for? Could any one please help me out.

Also does any one know any models for radiator and fan coil unit. If there is no standard model then how I can get non standard models? Attached with this email is my project's .tpf file.

 

 

Thanks

 

Looking forward to hearing from you.

 

 

Kindest Regards
