Hello,
I’m trying to model in TRNSYS 17 a system that comprises: solar panels + controller + battery + load. I’m trying to keep the model stand-alone, i.e. without any grid interconnection, but I
couldn’t figure out how to set my controller to exclude the grid.
Is that possible? If so, how could I do it?
Thanks in advance for your help,
Best regards,
Enrico Chinello

Al-Hyari,
It is not really possible to know what might be going wrong without running the project. What I would suggest is that you make a new project to which you add only the exhaust and outdoor air fans. Make sure they are the right size by adjusting parameter
values and run the simulation using an online plotter to verify that the temperature, humidity and flow rate leaving the fans is as you planned for it to be. Next, add the heat wheel into the system. Again, make sure that the parameters are correctly set so
that the heat wheel is appropriately sized to the application. Again, use the online plotter to verify that the temperatures, humidities, and flow rates exiting the wheel make sense. Keep adding one component at a time and verifying as you go.
kind regards,
David

so i tried by my own to build the model for an AHU Equipped with a heat wheel and auxiliary dx coil connected to a VRV System
i want to know the values of temperature and relative humidity before and after the heat wheel. but there is some mistake that i can not figure it out.
please advise me what can i do to make the correct model to simulate
in the attached files you can find the trnsys model and the schematic diagram for the AHU
It is my pleasure to join this discussing group mail.
I am working to simulate an AHU equipped with Heat wheel and an auxiliary dx coil connected to a VRV system.
I am new on TrnSys and i don't have much knowledge.
So if any one could help me by sendeng a similar example to study on it and make modification on the block diagram i would be highly appreciated.
