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

Hi Everyone,
I am having trouble with the TYPE-53 for vapor
compression chillers.
I am getting an error message which says ”the chiller is
operating outside of the range defined by the
performance curve fit”. However, I cannot see what the
problem is. I have checked the data and everything look
well.
There is no examples with this type
included in the provided information with the
software.
Has someone worked
with this TYPE-53?.
Does have someone an example using this TYPE-53?.
Thanks,
Javier Galvan
