[TRNSYS-users] TESS Chiller Models

[Santiago Naranjo Palacio <sn377@cornell.edu>]

Dear TRNSYS-users,

I have been using both of the chiller models supplied by TESS (Type 655 and 666) and I have a couple of questions regarding the data files needed to use them. How were exactly these numbers obtained (the Capacity Ratio and COP ratio)? I am trying to use the chillers for different chilled water temperature settings and ambient temperatures and I was wondering how to do this. If I understand the model correctly, this means that these chillers only approximate power consumption based on the data provided and there is no other criteria. Correct?

I would greatly appreciate any input.

Thanks
