[TRNSYS-users] ChillerType 53!

Dear Cagatay,
   Type53 reads its own data file and then calls a curve fitting routine to 
internally produce a performance curve for the chillers. The format of the 
data that Type53 is expecting is simply a series of n lines each having 
three entries, an X, a Y, and a Z value. The number of lines in the file is 
dictated by the value of parameter 5. There should not be any header lines 
in the data file. The extension of the file (*.dat or *.txt does not 
matter; Type53 is simply looking for a text file and does not care what 
extension is used.) I am not sure what the exact problem is but if the 
above hints do not help, I would suggest contacting your distributor directly.

that is correct. Type53 reads its own data file.

an integrator would be used if you wanted to know total power consumption 
of the chillers over each day, each month, or over the entire simulation. I 
would recommend using a combination of Type24 for integrating and Type25 
for printing.

I am not sure whether we have any such data files.

Kind regards,
