   The sample data file does come from an actual chiller and it is 
common to see much higher COPs when the chiller is running at part load. 
One thing to bear in mind, though is that while data in the external 
file is interpolated within the range covered by the file, it is not 
extrapolated beyond the range given. If you have a poorly sized chiller 
and it is running at some point either above or below the range in the 
data file, you may not get correct results. It is always best to use a 
data file for the chiller that you want to use. Such data is available 
at manufacturer's websites. TRNSYS does not have the ability to autosize 
Kind regards,
