Dear Malike,

 

I can write you only about type 56 issue:

1)      To generate heat demand you need to create building, e.g. using Trnsys3d plug-in to google sketch up (if you have Trnsys on your computer you should have tutorial to do it). When your building in google sketch up will be ready you need to import it to Trnsys and there will be a few default outputs from building. One of them will be indoor temperature of each zone and other will be energy demand of each zone. Then you need to connect them to some output type (plotter, or printer to file…, in your *.tpf file is type that plot graph and also print file.

 

2)      To put building in your simulation you need to add type 56 to the scheme: View->Toolbar->Direct Access, then choose Loads and Structures->Multi-Zone Building, then put type 56 icon on scheme, click on type icon, then choose tab ‘External file’ and show where is the *.bui file of your building. On the end you need to connect building module to other types (e.g. weather data). The last step is quite complicate, so better is to create new scheme base on building file (File-> New-> 3D Building Project, and follow windows/wizzard) and then add other types (e.g. solar collector etc.)

 

Good luck,

Karol

Dear all,


I'm trying to perform simulation for solar thermal system for water and space heating. In my project I have to size solar system for the school. 
TRNSYS provides some examples of solar systems and I decided to use one of them (scheme is attached - SDHW with heater).

Hot water demand 1020 liters per day, I put this value in the formula in Daily Load component (mdDHW= DHWProfile * 1020  ! Multiply by daily consumption). 
Is it right? 
Also when I try to make simulation for one year ( from 1 to 8760 hours), it shows me an error, that I have a problem with a deck file. 
My simulation time step is 0.25. 


In order to find space heating demand the Type 56 was used, however I found only temperatures inside of the building, scheme is attached ( file Wizard_check).
How to find heating demand? ( Q=AU(Ti-Ta))

Is it possible to perform all calculation on the one scheme instead of two? How to connect them?


I will be appreciated for any help,
It is very important project for me,

Thanks in advance,

Malike
