Subject: Re: [TRNSYS-users] Type 56
Abduljalil,
In order to change the wall layers, open TRNBuild and open your building description file (*.bui or *.b17). Select Typemanager: Walls from the menus at the top of the screen. Select the appropriate wall from the drop-down list. Double click on a layer in order to change its thickness.
Best,
David

I am a new trnsys user and I want to change the thickness of the wall insulation in the tape 56 ( multi-zone building ). Is it possible to change this thickness in this type ex. for insulation = 5 cm to 20 cm step 5cm.
I would like to study the effect of insulation thick to the performance of the system
best regards

Subject: Re: [TRNSYS-users] Psychrometrics
Jérôme,
What is most likely happening is that at a pressure of 1atm, your combination of the dry bulb temperature and the absolute humidity ratio are on the wrong side of the saturation line. Since that is physically impossible, the psychometric routine keeps your dry bulb temperature and resets the absolute humidity ratio to the value it would be if the relative humidity were 100%.
Best,
David

i'm using a psychrometrics type with dry bulb temperature and absolute humidity ratio in inputs. Pressure input is set to 1 atm.
I have noticed that sometimes there is a difference between the input humidity ratio and the output humidity ratio. The difference ratio is about 1 to 12%.
Could someone explain to me why this difference happens?
Thank you

Subject: [TRNSYS-users] error when opening sketchup
Hi,
I am using the TRNSYS 3d plugin for SketchUp V7. I have v8 but the plugin doesn’t seem to attach to v8 (is this correct? Is there a plugin for v8). Whenever I open sketch up I get the following error:
Sorry… the plugin has encountered an error. This error may cause unpredictable behavior in the plugin continue this session with caution! It would probably be a good idea to exit SketchUp and start again. (unfortunately this happens everytime I open sketchup)
For help please contact…
Error:

Wrong constant name jectinfoInterface

Can you help
Thanks
