Hallo,
I am simulating a heating system with heat pump and a boiler. For this I am using an available load profile as well as the set poit building temperature (see screenshot). Unfotunately after the simulation I am getting the notification that the heat capacity of system is not met, as well as the set building temperature was not reached. I have also tried just using 18 °C as the set building temperature (in excel). However, when I input the total energy demand of the building (without using my own load profile) the simulation works just fine.
The problem apparently seems that the mixing valve is not taking the set point temperature (from excel) and hence is most of the time 90% closed.
Would be great if someone can give me some hints on how I shall proceed further.
Thank you,
Z

Dear Zaideus
Could I ask you to send us a screenshot of the settings of the heat/cooling controller:
I simulated a similar project with hourly values and it worked well.
Thx & regards![Wink ;-)](./images/smilies/icon_e_wink.gif)

I am getting the same error when using quasi dynamic model and temperature 19 degrees, but the simulation is working fine with soll Temperatur 16 degrees.
I tried increasing the number of heat elements and power of heat pumps. But it didn't work. I will post the screenshot as soon as possible.
Thank you.

Hallo Polysun_CAH69,
Thank you for your reply, attached is the requested screenshot. It seems that due to large number of heating elements (100 floor heaters), a large flow rate is required (8000 l/h), but the supplied hot fluid flow from buffer is very less even though the buffer is big enough (10000 l) . Most of the back flow is being directed again into the system and the radiator soll temperature for forward flow is not achieved.
Thank you

Sehr geehrter Herr Zaideus
Ohne *.pse File können wir die Sachlage nicht beurteilen.
