<div dir="ltr">Hello,<div><br></div><div>I am trying to model a solar heating system for a leisure home in ESP-r. </div><div><br></div><div>At first I tried to build the model in ESP-r version 12.0 with the following Build information:</div>
<div>-SVN source - development_branch@r9412 (unmodified)</div><div>-Platform- x86_64:Linux:3.8.0-29-generic</div><div>-Compilers- gcc/g++/gfortran</div><div><br></div><div>It seems that the plantsdb is missing. When i choose database maintenance->plant components->browse/edit, no list of plant components appears at all. In the terminal it says 'Error: -mode does not exist', while in the ESP-r window it says 'There are 112 components in plantc.db1'. I tried to open the same database on three different computers using the same version of ESP-r (version 12.0). The same error message was encountered on the two other computers. </div>
<div><br></div><div>-Does anyone know if there is a problem with the plantsdb in this version of ESP-r, or how I can fix this problem?</div><div><br></div><div>I then tried to build the model with an older version, ESP-r version 11.4 with the following Build information:</div>
<div>-SVN source: trunk@r2123 (locally modified)</div><div>-Platform: i86:Linux:2.6.23.1-21.fc7</div><div>-Compilers: gcc/g++/g77</div><div><br></div><div>In the 11.4 version i was able to open the plantsdb and a list of the available components appeared. The problem I am having with this version is that I am not able to define a sensor that is supposed to sense the temperature difference between a solar collector and a storage tank. (This part was clear in the 12.0 version)</div>
<div><br></div><div><div style="font-family:arial,sans-serif;font-size:13px">Under Controls->Plants and systems-> sensor details-> senses output of a plant component, i chose the solar collector as the "plant component for sensor". I was then asked: "Plant component node for sensor?" and I assumed that because I have a one-node flat plate collector that the answer to this was 1. A followup question appeared: "2nd Plant component index for sensor?". What number/index are they asking for here? I tried to write the index number for the plants database for the tank but it does not seem to work. I also tried with the index of the tank in my plant network file (i.e. the number of the plant component there). </div>
<div style="font-family:arial,sans-serif;font-size:13px">When i run the simulation and open results analysis, a warning appears:</div><div style="font-family:arial,sans-serif;font-size:13px">WARNING in filename.cfg: no chars found for plnt res string in: *splr</div>
<div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">Does anyone know how to fix either of these two problems? All help is much appreciated!</div><div style="font-family:arial,sans-serif;font-size:13px">
