[TRNSYS-users] Type 655 problem with external files

[Santeri Siren]

Dear all,

I think I have some major problems with air cooled chiller type 655. I
created a simple example project where I change the ambient temperature
over time and see how the COP reacts. But the COP doesnt change at all. It
seems that the air cooled chiller doesnt read the external data file as it
should. I used the example files provided with the TESS HVAC package as the
external performance files.

When I change the chilled water setpoint tepmerature over time then the COP
changes but even then the chiller power doesnt change. Have you any idea
why this is happening?

By the way, I do know that in the performance file the cop rating should be
in the first column. However this doesnt change the fact that the ambient
air temperature doesnt affect the COP. I have attached a picture of my
simulation.

Thank you for advance!!

best regards. Santeri Siren
