Leona, Did you create the user defined schedule "BUEROKZIMMER" (unless this schedule is part of a non-English version of a TRNSYS library) in a different building project? I would manually edit the bui file in a text editor. I found it was quicker for some things compared to using TRNBUILD. If you have used this schedule in a different simulation you can just copy and paste the code into your current bui file. After that I would save this schedule in a user library. Also did you or someone else create this schedule on a different computer, the machine you are currently using have may not have it loaded. What I believe is happening is that you are calling a schedule that is not saved in any user libraries in TRNSYS, or not stored in the right place. When you open the file in text editor you will need to edit this section. * S c h e d u l e s *-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- SCHEDULE WORKDAY HOURS =0.000 8.000 18.000 24.0 VALUES=0 1. 0 0 SCHEDULE WEEKEND HOURS =0.000 1.000 24.0 VALUES=0 0 0 SCHEDULE WORKLIGHT HOURS =0.000 8.000 18.000 24.0 VALUES=0 1. 0 0 SCHEDULE USE DAYS=1 2 3 4 5 6 7 HOURLY=WORKDAY WORKDAY WORKDAY WORKDAY WORKDAY WEEKEND WEEKEND SCHEDULE LIGHT DAYS=1 2 3 4 5 6 7 HOURLY=WORKLIGHT WORKLIGHT WORKLIGHT WORKLIGHT WORKLIGHT WEEKEND WEEKEND Hope this helps. Aaron Danenberg From: 瞳瞳 [mailto:ilyt2000@gmail.com] Dear all, I am trying to make a simple room model to caluate the cold load. Now i have inputed all the data in the TRNBild and when i ran it, i got the information : Scheduletype<BUEROKZIMMER> not found. It is a daily schedule , and for the office room. My questions are 1. How can i solve the TRNBild problem? 2. What is the next step? make it as a external file in Type 56? 3. Which Types or componentes do i need to run the calculation. Type 109? Type 25? Thanks a lot for everyone who could explain me that. Leona |
