[TRNSYS-users] Implementation of TESS-Type 669

[info.bauklima]

Hi Jeff,

There is a mistake in proformo definition - see appendix
But why are there no outputs for energy-values, because of wrong performa
definition.
flowrate ist evaluated as pressure I guess.
Does the mistake in the proforma - definition generate zero values for
calculated energy-values ?

Regards

Heinrich

<I would like to use the TYPE "696b" of the TESS-HVAC-library in my project,
to model the energy-consumption of a simple AC-Unit. But when I checked the
studio example, that I got from TRANSSOLAR , I realized that there is no
possibility to evaluate the energy output of the component.>

The outputs of the model from the proforma should be:

OUT(1)=Outlet air temperature
OUT(2)=Outlet air humidity ratio
OUT(3)=Outlet air percent relative humidity OUT(4)=Outlet air flow rate
OUT(5)=Outlet air pressure OUT(6)=Sensible energy requirement in heating
mode OUT(7)=Latent energy requirement in heating mode OUT(8)=Total
(sensible+latent) energy requirement in cooling mode OUT(9)=Sensible energy
requirement in cooling mode OUT(10)=Latent energy requirement in cooling
mode OUT(11)=Required reheat energy

Please let me know what the outputs are in the proforma that you are using.

Thanks!

Jeff
