Dear all,<br><br> I made the simulation using TRNSYS Wizard, however, after that I got a TRNSYS Bug. Please see the attached figure which is the bug I met. (English meaning:*.bui file <span id="result_box" class="short_text" lang="en"><span class="hps">contains</span> <span class="hps">an invalid path</span></span> )<br>
<br>Do you experts have some solutions or advices for that? <br><br>Once I use the TRNSYS Wizard to produce other any new program, it appears this bug all the time. If I can not deal with it, I will not continue to work using TRNSYS.<br>
<br> <br><br>Many thanks in advance!<br><br>Br.<br><br>wang<br><br><br><br><div class="gmail_quote">2012/6/1 <span dir="ltr"><<a href="mailto:trnsys-users-request@cae.wisc.edu" target="_blank">trnsys-users-request@cae.wisc.edu</a>></span><br>

<p class="MsoNormal"><span lang="EN-US">Hi Trnsys-users,</span></p><p class="MsoNormal"><span lang="EN-US"><br></span></p>
<p class="MsoNormal"><span lang="EN-US">I modeled a
chilled water system with several fans coils unit on TRNSYS, I focalize on the
repartition of the flow rate in it. The point is, I don’t know if there is a
configuration which considers the water delay from the pump to the coils. And
if the type 31 (pipe) induce a new flow rate repartition because of the
pressure difference. And if I want that how I do ?</span></p><p class="MsoNormal"><span lang="EN-US"><br></span></p>

<div><br></div><div>I have read a couple of messages in the archives about this topic but I haven´t understood correctly the few addressing my specific issue. </div>
<div><br></div><div>Here is my point. I assume the heat pump to meet the building demand. The aim is then to force the heat pump load and observe how the system behaves (COP, ground loop fluid temperatures). </div><div><br>
</div><div>I would be able to do this with an external MATLAB code (with COP values interpolated from catalog data) but it would be a shame not to harness TRNSYS potential (there is no need to re-invent the wheel as I read in a previous message). </div>
<div><br></div><div>Let me put in other words: how to control a heat pump load? </div><div><br></div><div>I have read about a trick to handle this, with a "lump" temperature but I don't get the idea behind it. Any other explanations is welcomed. </div>
<div><br></div><div><br></div><div><br></div><div>Thanks in advance,</div><div><br></div><div>Best regards,<br clear="all"><div><br></div><div><br></div>-- <br><div><font color="#999999"><b>Damien Casetta</b></font></div>
