Wang,<br>
When you use TRNFlow, you are allowing Type56 to compute
interzonal air flow rates based on the external environmental
conditions that you are imposing (from a weather file for example).
I suppose that you would have to tune either the environmental
conditions or the amount of openings in your building envelope so
that you get an infiltration rate (calculated by TRNFlow) that
approximates the value that you measured (0.53 ach/h)<br>

TRNFLOW, the defined infiltration rate as 0.5276 1/h in TRNBUILD

Please explain this! Or tell me how to compare the test room

TRNBuild offers an output (NTYPE96) which is the
air change rate of infiltration. TRNBuild also
offers an output for the energy gain (or loss) from
infiltration (NTYPE4)<br>

I defined CO2% as 1000 ppm in TRNFlow, then I

Please tell me how to get the infiltration

Subject: [TRNSYS-users] Problems with
calling EES (Type66a)<br>
<div>
<div>Dear TRNSYS users,</div>
<div> </div>
<div><font face="times new roman">When
simulating an applied thermal
system, I'm using EES for the
hydronic part. I programmed the
hydronic circuit in EES and
coupled it with TRNSYS via Type
66a. This coupling works fine,
but;</font></div>
<div> </div>
<div><font face="times new roman">The
problem is that the simulation
runs very slow. Every timestep
that TRNSYS calls EES, the EES
project is opened and closed. Is
there a way to set some settings
so EES isen't closed and
reopened each time, this would
minimize the solution time alot.</font></div>
<div> </div>
<div><font face="times new roman">Thanks
on advance</font></div>
