[TRNSYS-users] Confusing results with a bui simulation.

[Elias Sasati]

Dear TRNSYS users,


   I am running a simulation, testing the heating needs of a building and
the weird thing is that I get also cooling values for a zone. If I change
the heating schedule for that zone I don't get any cooling results. While in
the summary results (T56_std-Output.txt) the cooling values appear in the
results, the sum of cooling power for that particular zone is zero
(T56_std-q.xlsx) making it more complex to find the error.
  As you can see in the attached files the problem is spotted in ZONE 11 and
month May. Though, if you open "T56_std-q.xlsx" the sum of ZONE_11 (11_COOL
, column AA) is zero. The results are correct if I use the FIXED20 heating
schedule. (See bui_info.txt for more information about bui)
 Does anyone else encounter similar problems?


Thank you for your time,
Elias
