[TRNSYS-users] Heating Type Manager (Heating Load is too high)

[Asma Sohail]

Hello trnsys-users,

this is Asma from the University of Stuttgart. Right now I'm working at my diploma thesis using TRNSYS and a problem occured we were not able to solve yet. I hope that you might have a solution or an idea how to fix it. In TRNBuild I'm using the Heating Type Manager with unlimited power to heat a room to a  certain temperature (20°C). I'm only using convective heat. But something is not working properly with the simulation. I get a heating load that is far too high for certain rooms. Specifically, it is about interior rooms with a too high heating load. I've already checked all links or sources of error, but haven't found anything that causes an error. My maximum specific heating load should actually be around 40 W / m² (144 kJ / h per m²), but I get around 100 W/m² (360 kJ/h per m²), although the outside temperature does not fall into the minus range. It would be great if you had an idea
how to fix that or if you could identify the problem. Thank you very much in advance!! I attached the files I used in case you have time to have a look at them.

Thanks and kind regards

Asma
