Farah,<br>
with Type60, you have to specify three of the four flow rates. In
your case, you need to connect the collector loop pump outlet flow
rate to both tank inlet 2 and tank outlet 2. You correctly connected
the load flow to tank inlet 1. If that is what you've done and the
results don't make sense, please send the input file.<br>
<br>
Incidentally, in your case of matched flows and no heat exchanger,
there isn't any real need to use Type60; Type4 is a bit more
intuitive and may suit your needs.<br>
Best,<br>

<p class="MsoNormal">I am modelling a solar collector with hot
water storage tank (Type60c). I connected the collector
outlets to the tank inlets2, the tank outlets2 to the
collector inlets, and I set the tank flow rate at outlet2 to
“-2” (constant tank volume). On the other side of the tank, I
connected a load (mass flow rate) to the tank inlet1, and I
expected that the same mass flow rate will come out of the
tank outlet1. However, the flow rate at outlet1 is 0
throughout the entire simulation, and the load mass flow rate
connected to the tank inlet1 is added to the mass flow rate at
outlet2 (collector side) instead of outlet1.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In equations format:<o:p></o:p></p>
<p class="MsoNormal">MassFlowRateOut2 = MassFlowRateIn2 +
MassFlowRateIn1<o:p></o:p></p>
<p class="MsoNormal">MassFlowRateOut1 = 0<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It should be:<o:p></o:p></p>
<p class="MsoNormal">MassFlowRateOut2 = MassFlowRateIn2<o:p></o:p></p>
<p class="MsoNormal">MassFlowRateOut1 = MassFlowRateIn1<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any help how to fix this is highly
