Re: [TRNSYS-users] Unheated Space

[David Bradley <bradley@tess-inc.com>]

Samar,
 I am a bit unclear on what you are trying to do. Typically an unheated space would not have any set point associated with it; the temperature would simply float and there would be no heating load on that space. If you are modeling such a space but there is a heated space next to it, you can treat the wall in between as a BOUNDARY wall in TRNBuild and specify the surface temperature of the back side (the side that is in the conditioned space, not the side that is in the unheated space). Note that what you are asked to specify is the surface temperature, not the temperature of the air in the adjacent space but as a first guess, you could probably assume that the surface is at the set point temperature.
Best,
 David

Dear All,

I am trying to calculate the heating and cooling load by using TRNSbuild. 

The problem that I have an entrance in my model which considers as unheated spaces with set point temperature around 18 C as the same time it is adjacent with other volume's.

Is there any ways to translate this adjacent wall with temperature condition into TRNSbuild?

Thank you for your kind assisstance in advance.

Samar
