initial CO2% as 1000 ppm(0.00164 kg/kg) in the test

CO2% as 400 ppm(0.00065726 kg/kg) doesn't work, the
indoor CO2% reduce beyond 400 ppm(0.00065726 kg/kg)
and up to 6.00E-10kg/kg, i think the air flow rate in
test data works all the time, the ambient CO2% as 400
ppm(0.00065726 kg/kg) doesn't work.<br>
So I defined an Equation in simulation studio: when
CONZ(the indoor CO2% )<0.00065726, air flow factor
is 0. What's the meaning of air flow factor?<br>
I think the above problem's reason is air flow
factor(1) works all the time. Is my thought right or
not? Please see the ATTACHED 1st and 2nd. Please have
a look at my programs whether are they right or not?
If not please correct them. thanks!<br>
<br>
<br>
<br>
But after running, I found CO2% reducing rate of the
curve is very faster than my actual measurement in the
test room. Please see the ATTACTED 3rd and 4th. To 3rd
you can see only about 2 hours the CO2% got to 400
ppm(0.00065726 kg/kg), but to 4th the actual
measurement curve in the test room: it needs about 10
hours to get to 400 ppm(0.00065726 kg/kg). Please
explain it, why the difference is so bigger? Or please
see the ATTACHED 1st and 2nd to verify the CO2%
reducing curve in TRNFlow with ATTACTED 4th the actual
measurement curve.<br>
<br>
2. Please tell me how to get the CO2% data etc. of
TRNFlow output after running?<br>
<br>
Many thanks!<br>

<p>Dear Mr. Frenzel,<br>
<br>
Thanks!<br>
<br>
In the TRNFlow manual: there it
is explained that "As soon as TRNFLOW
is turned on, (...) in the simulation
the defined infiltrations,
ventilations and couplings will be
replaced with the calculated air
flows." The fact is that I
defined initial CO2% as 1000
ppm(0.00164 kg/kg) in the test room in
TRNFlow, and I defined the ambient
CO2% as 380 ppm(0.0005819 kg/kg).
Meanwhile, I defined the infiltration
rate as 0.5276 1/h in TRNBUILD. I
want to compare the CO2% reducing
curve in the test room based on the
infiltration rate 0.5276 1/h of
actual measurement value with by
TRNSYS simulation. But when I used
TRNFLOW, the defined infiltration rate
as 0.5276 1/h in TRNBUILD was replaced
maybe. 1000 ppm in the test room
keeps constant. Please see the
ATTACHED.<br>
<br>
Please explain this! Or tell me
how to define in TRNSYS/TRNFlow in
order to compare the test room
infiltration rate of actual
measurement value with by
TRNSYS/TRNFlow simulation? I want to
observe CO2%'s reducing curve when
infiltration rate is 0.5276 1/h (I
measured the value in the test room)
using TRNSYS/TRNFlow, to observe the
CO2%'s reducing curve whether is the
same as the actual measuring CO2%'s
reducing curve or not?<br>
<br>
Many thanks!<br>

<p>Dear Mr. Frenzel,<br>
<br>
Many thanks!<br>
<br>
After I installed both of
them once again, it's OK.<br>
<br>
1. To radiative part: The
test room has 2 heatings:
one is radiator, its power
is 578 W, another is
convector, its power is
540 W. How can I define
this situation's radiative
part? As you said can I
think both of them have
only convective part? So I
define the radiative part
is 0 or not? As you know,
it is very difficult to
make sure what's the
convective and radiative
part of this test room
situation. But my
professor let me figure it
out, so can I define the
radiative part as 0? Or do
you have some experience
about this radiative part
defining?<br>
<br>
2. To thermal time
constant: Thermal time
constants are a feature of
the <a title="Lumped system
analysis" href="http://en.wikipedia.org/wiki/Lumped_system_analysis" target="_blank">lumped
system analysis</a>
(lumped capacity analysis
method) for thermal
systems, used when objects
cool or warm uniformly
under the influence of
convective cooling or
warming. In this case, the
heat transfer from the
body to the ambient at a
given time is proportional
to the temperature
difference between the
body and the ambient.<br>
Physically, the constant
represents the time it
takes the system's <a href="http://en.wikipedia.org/wiki/Step_response" target="_blank">step
response</a> to reach <img src="" alt="1-1/e \approx
63.2%">
of its final (asymptotic)
value. <br>
<br>
Please see ATTACHED 1st:
Tset-point is 21°C from 8
am to 6 pm, other is 20°C,
Thermal time constant of
this test room is the time
that Tindoor air gets to
the 20°C
+63.2%(21-20°C)=20.632°C.
But this is at the
situation of floor
heating. I want to
simulate the situation
when using Radiator and
Convector. <br>
Please see ATTACHED 2nd:
The result is very
strange. T indoor air
which rises from lower
temperature to higher
appeares 3 jumps, this is
very strange, because I
closed all the windows and
turned off TRNFLOW, only
defined the infiltration
in order to simulate the
actual situation of the
test room. But, meanwhile,
QHeat is keeping constant.<br>
Please see the .tpf and
,bui files of ATTACHED. </p>
<div><br>
Please tell me how to get
the thermal time constant
of the test room using
TRNSYS? Or how to explain
to my professor the ideal
heating? <br>
<br>
<br>
<br>
</div>
3. To ideal heating: Where
is this heating? Can I
define its position? How is
it operating or working?<span></span><span></span><span></span><br>

<div> 2. I
defined a set

temperature:20C
from 8 am to 6
pm, other time
is 18 C in the
test room . I
used the
HEATING to
realize it,
but the

ideal heating.
Please tell me
what's the

ideal heating?
</div>
<div> The
result is the
indoor
temperature
can get to the
set point at
once and no
time delay, so
I cann't get
the THERMAL
TIME CONSTANT
of the test
room. But my
professor let
me use TRNSYS
to verify the
result of
using TRNSYS
to calculate
the time
constant and
actual
measurement
test room
result of time
constant.
Please tell me
how to get the

using TRNSYS?
Or how to

<div>2. Indeed

you mean the

Did you see

I got the

I think
TNRSYS's
results are
questionable.
Why I turn off
the

is there still
having QINF? <span><font color="#0000ff" face="Arial" size="2"> </font></span> </div>
