<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">You actually might be in luck with the provided TESS sample catalog data for your micro CHP system. There is a popular micro CHP system that is manufactured here
in Wisconsin, the “Marathon Engine” or the Ecopower, and it produces 5.5 kW electric and 12.5 kW thermal (from the 4 HXs that you mentioned) that runs on natural gas or propane. It used to be manufactured in Germany or Austria, so perhaps it is the same or
very similar system? I was on a project team that helped implement the system in an energy systems laboratory at MSOE, and there was another TRNSYS user that implemented a system at the University of Maryland. Nonetheless, there is an external data file for
a similar an IC engine system that is provided with the TESS Libraries:<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">As you can see from the comments and the values in the data file, the majority of the thermal energy from this goes into the jacket and the exhaust. It does not
have waste heat from the generator in this particular data file.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">However, I cannot stress enough what Jeff mentioned: take your time, take a step back, make sure this data file (with PLRs and fractional waste heat values) aligns
to your particular system, get this piece working first, and then proceed with the rest of your simulation once you have that piece set. There is also a very simple example with this data file in Type907 with a simple exhaust heat exchanger for reference:<o:p></o:p></span></p>

<p>I took a look at your project and I think you should take a step back and work on things a bit at a time. I've attached a simple project showing how a 70 C cooling stream is connected to an IC Engine with a varying load. Take the time to completely understand
how this project works before connecting up the tank, condenser, tank cooling stream etc. Remember that the odds of the default engine performance files being identical to your particular machine are small - you may have to modify the parameters and external
files to match your given simulation. Your question as to "Next, I have thermal load profiles in kWh. I don't know how I can integrate the load to unload the storage." How do they do it in real life? There's your answer. I'm guessing they have a pumped
flow through the tank that uses the thermal energy. Try the flowstream loads component, controllers, pipes, pumps etc to mimic the real world system.<o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif">thank you for your fast answer. In my mail before, I said that I want to load the thermal storage tank with the heat out of the exchangers. I tried to simulate a real CHP unit
with 5.5 kW elec and 12.5 kW thermic. The CHP unit works just in full load, that means "on" or "off". There are four HX in the CHP to gain the heat out of generator, oil cooler, water jacket and exhaust. At the outlet of the CHP should be 83 °C to load the
storage with that temperature and back to the CHP after the condenser with 70 °C (max.). There is a fluid flowrate to cool the components with 823 kg/hr. But I don't get the desired 83 °C. There must be a mistake between oil cooler and water jacket as you
can see in the plot. A pdf with the function principle is in the Annex.<o:p></o:p></span></p>

CHP with 70°C, because the "load side" is incomplete. The load side is should be a HX to dump the arriving heat. So there is no unloading of the storage.<o:p></o:p></span></p>
