class=673524507-18052011>the main reason for your troubles is the groundfloor in
zone 1ST_L. There is a small surface overlapping with the big one. I removed
this and it works. But you have a lot of wrong adjacent walls and also the
window in the ceiling of zone 5TH_L is wrong. So I did some more changes to your
model. I do not know if everything is correct.</SPAN></FONT></DIV>
<DIV dir=ltr align=left><FONT color=#0000ff size=2 face=Arial><SPAN
class=673524507-18052011>My advise working with sketchup and TRNBUILD: Do not
draw the whole model and try to import it at last. Always work step by step.
Draw the first zone, try to import it check it and if everything is ok do the
next zone. Save often import often and keep all steps in seperat
files.</SPAN></FONT></DIV>

sketchup in order to create the IDF file. but i can not input to the simulation
studio when i use the trnsys muti-zone option. If any one can tell the reason, i
really appreciate it.I really don't wanna waste another whole day to redo it
! Thank you so much much!! <BR>And the IDF file is attached.<BR>waiting
for your reply!<BR><BR>And by the way, i found a err for the newest version of
simulation studio. when i input the trnsys 3d using the IDF, i found the
capacitance is set 0 automatically while the old version 17.000007 works well.

performance question<BR><SPAN
style="BORDER-COLLAPSE: collapse; FONT-FAMILY: arial, sans-serif; FONT-SIZE: 13px">Hey
all,
<DIV><BR></DIV>
<DIV>I have a question about the Type553 Unglazed collector and how it's
performance interacts when changing flowrates in two different scenarios. I
was wondering if someone could help explain the trend in a practical way for
me so I can explain it to my colleague.</DIV>
<DIV><BR></DIV>
<DIV>First off, when just running a constant flowrate and
constant incoming temperature as the inputs to the collector, I can
see that increasing that flowrate increases the useful energy out of the
collector. This makes sense and is intuitive.</DIV>
<DIV><BR>Now when I use a loop instead for the same collector, (say with a
pump operating at 1 GPM just as a starting point), and a perfect heat
exchanger with the same incoming water temp now on the load side of the HX, I
see a different trend I'm having trouble explaining to my colleague.</DIV>
<DIV><BR></DIV>
<DIV>What is happening is that the useful energy increases like the first
scenario, but only up to the flowrate that is on the load side of the
HX. <I>ex. So if I have 5 GPM on my load side, I see an increase in
performance up to 5 gpm on my collector side, and then the performance begins
to drop after increasing it any further.</I></DIV>
<DIV><BR></DIV>
<DIV>Another way to say it is that whenever my flowrate of the collector array
is greater then my load I have weakened performance. It seems that a
1:1 flow ratio on each side of the HX is the optimal method (assuming same
specific heats).</DIV>
<DIV><BR></DIV>
<DIV>Can anyway explain in a conceptual manner why there is this
decrease only when using the HX? I was thinking that because the load side of
the HX is the limiting flow (the one that isn't changing) then because the
collector flow is higher, that not all the heat from the collector can be
transfered, leaving the outlet of the HX on the collector side hotter than if
the flows were balanced. Thus in turn lowering the efficiency
and available energy to be collected the next time it passes through
the collector.</DIV>
<DIV><BR></DIV>
<DIV>I can actually see the source side temp coming out of the HX hotter than
the incoming water when the collector flow is higher, but my colleague still
thinks the energy should not drop. He believes that when increasing the
flow up to a very large number over many trials, the useful energy will always
rise up until it levels off asymptotically, whereas in my case, it is
doing more of a bell curve and dropping off after it becomes higher than the
load flowrate.</DIV>
<DIV><BR></DIV>
<DIV>Thanks for any help.</DIV>

<P class=MsoNormal>Dear All,</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>I am searching for a experimentally validated unglazed
collector setting in TRNSYS (with values of Inputs, Parameters, assumptions,
etc.).</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>I am currently working on an unglazed polymer PVT collector
with rectangular flow channels (so NOT a fin-type collector.</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>I would like to compare my attempts with similar systems.
As there are probably no "really similar" systems available, any validated
solar collector model will be helpful.</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>Ideally with long term measurements validation.</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>Can someone comment on the accuracy of the default values
for the collector types, e.g. is it a good enough reference to simply use a
TRNSYS type out of the box? </P>
<P class=MsoNormal> </P>
<P class=MsoNormal>Would some standard decks from IEA tasks work (I
think they exist, right?) for my purpose?</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>I am currently reading about <B>Type 132</B>, but till now
I could not find any download link (and it should be openly available if I
understood correctly). </P>
<P class=MsoNormal>Can anyone help on that?</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>I am not sure about the validity of my potential results,
as I do not have a prototype yet, so I try to judge how I could somewhat
validate by comparison.</P>
