[TRNSYS-users] Has someone worked with TYPE-53?

[David BRADLEY]

Javier,
   Although Type53 does not use the standard TRNSYS external data file 
format, some of the same rules still apply: the model can interpolate 
performance inside the range of data given in the file but it cannot 
extrapolate beyond the range given. In the case of Type53m you get an 
error if your data file does not cover the range of your inlet 
conditions. Take the second data variable for example. The values are 
ratios of the temperature difference between the condenser water outlet 
and the evaporator water outlet relative to a specified design 
temperature difference. If the maximum temperature difference in the 
data file is 10C and then during your simulation, the temperature 
difference goes as high as 15C, you will get an error. If you aren't 
able to find which of your input variables is going out of the range, 
please send me the simulation that you are trying to run and I'll see if 
I can find it.
Kind regards,
  David
