[TRNSYS-users] Hot water absorption chiller

   In order to get the simulation to run you can put in the same COP and 
capacity data twice into the file, once with a 1.0 part load ratio and 
again with a lower part load ratio. I want to stress, though, that while 
that will make the simulation run, you aren't going to get meaningful 
results out of your simulation unless you can find some part load data. 
Otherwise the chiller is going to run at its full load capacity and COP 
no matter what the inlet conditions to it are.
