[TRNSYS-users] Heat Pump Performance Data Files

[David BRADLEY]

Adrian,

   The data in the example files is from a real machine. I suspect the 
simplest thing to do would be to go to a manufacturer website and get 
data for a machine that covers the temperature range you need. The other 
alternative is that you can take the example data file and plot it in a 
spreadsheet program, look at the shape of the performance curves out 
near the limits of the temperature range specified, make an educated 
guess as to how the curve extrapolates, and then add data to the sample 
file.

kind regards,

  David
