<div>Betrand,<br> I think you are going to need to use two controllers. The first controller will determine the flow rate of your collector loop in order to maintain a collector outlet temperature of 70C. The other controller will determine the flow rate on the load side of your heat exchanger in order to maintain source side outlet temperature of 60C. I am also not sure that Type2 is an appropriate controller model; Type2 models a differential controller that has only two states: ON and OFF. In order to modulate your flow and maintain an outlet temperature, you will need to use a proportional or a PID controller. There are some solar collector models in the TESS Solar Library that combine a variable speed pump, controller, and collector and modulate the required inlet flow rate in order to maintain an outlet temperature.

<div>Meriem,<br><br>
<blockquote cite="http://" type="cite">1- In type 56, When you calculate the response factors of the walls, which properties do you take for the inside and the outside air layers?? Do you take the ASHRAE standard library (I mean the layer A0 for the outside surface resistance and the layer E0 for the inside surface resistance).
<br>How does this interfeer with the indicated values of (hc)int?</blockquote><br>The convection and radiation from the inside and outside surfaces of Type56 walls are calculated internally based on the user specified values of front side and back side solar absorptance and inside and outside convection coefficient. These values are specified in the wall type manager in TRNBuild. TRNBuild displays a wall u-value that includes estimated values of front and back side surface resistance but these values are for display only. The actual values are calculated during the simulation and are a function of current ambient conditions.
<br><br>
<blockquote cite="http://" type="cite">2-How to calculate response factors with variable values of convective heat transfer coefficient of wall (inputs/shedule values)??</blockquote><br>in order to see the time dependent, calculated values of the wall u-value, you need to choose the appropriate Type56 output NTYPE by clicking on the "outputs" button in the TRNBuild project window.
<br><br>
<blockquote cite="http://" type="cite">3-In the example "Restaurant" ; the convective heat transfer coefficient (back)of the wall "outside" is defined as = 1*HOUTSIDE; where HOUTSIDE is an input of type 56, and HOUTSIDE is not connected to any other type, that means that during the simulations, this parameter is equal to zero?? Why is that input not connected properly??
</blockquote><br>you are quite correct; that is an error in the example. There should be an equation that sets the value of HOUTSIDE and that equation should be connected to Type56's input. The equation should have the form:
<br><br>(AA+BB*WindVel+CC*WindVel**2)*3.6<br><br>where AA, BB, and CC are empirical coefficients that depend on the exterior surface material and WindVel is the wind speed. The AA, BB and CC coefficients (from ASHRAE) would be:
<br><br> AA BB CC<br>Stucco 11.58 5.894 0.0<br>Brick 12.49 4.065 0.028<br>Concrete 10.79 4.192 0.0<br>Wood
8.23 4.00 -0.057<br>Smooth plaster 10.22 3.1 0.0<br>Glass 8.23 3.33 -0.036<br><br>Thanks for finding that error.<br>David<br><br><br><br>
