Hey everyone, I recently faced a problem that I tried to fix with some users, but I didn't provide them with enough informations which was confusing. So I am posting this question to explain my issue from the beginning.
I am modelling a residential building of 12 flats whose HVAC should be as follows: District heating for both water usage and floor heating + Heat recovery ventilaion
So these 3 screenshots show the hot water system configuration:
As you can see below it is a mixed water heater but the fuel type is District Heating as suggested by @egillmor (otherwise the ''DHW usage will show up as heating end use rather than water system end use.'')
The rest of the screenshots will show the HR ventilation and radiant floor loop
Following the instructions of @MatthewSteen in this post I did this :
The simulation ran successfully, but the District heating consumption chart was illogical, as shown below: the consumption is more or less the same from April to November and it is also low in January, while it should be low fi the summer and gradually increasing during the winter.
Same problem the the Demand
Does anyone have any idea about what is wrong with my HVAC that had led to that result ??
I hope I made it clear , but if there is any information missing, please let me know.
I would appreciate a lot your help ! :)
