<p class="MsoNormal">Dear TRNSYS-users,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As part of my project, I have modeled a double bypass from a storage tank to a heat pump, but I am getting mass balance discrepancies (even though there are no such errors mentioned in the lst file). I have attached a diagram of the layout
to this email (similar to Figure 4.6.2-4).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I only seem to be getting this problem when both massflow4 and massflow5 are non-zero. In the screenshot attached, a slight difference in mass flow rates can be observed between massflow2(AtoC) and massflow2(DtoB). Also, massflow4 at the
diverter outlet is slightly different to the borehole flow rate… <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Has someone encountered this before? I have looked over the diverter equations and I tried to reduce the time step down to 0.01 hour but that doesn’t solve the problem. I have a simple example of this available, so I can send that on if
someone would like to take a look.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanking you in advance,<o:p></o:p></p>
