Warning: Heat capacity of system not met
Verfasst: Mi Apr 11, 2018 6:13 pm
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
