Re: [EnergyPlus_Support] Flow control between floor heater and solar storage tank [1 Attachment]
Hello Mr. Nikolic, hello to all other experts,
I have exactly the same problem you have or had. Have already found a way to make this work?
In my opinion the tempering valve is worthless the way it works currently in E+. It is only in charge for the regulation of the outflow of the solar tank when its temperature is too high. So overall there is a higher energy demand due to the fact that the return flow of the heating floor system is cooled down by mixing up with the colder water of the solar tank.
Currently I try to regulate the tempering valve by implementing an EMS as you have already mentioned. But this takes time because I am not familiar with that kind of Programming. You could be a great help!
Thanks in advance. I attached a sketch that illustrates my HVAC loops.
Regards,
Christian
