Dear Angela,<br><br> Many thanks for your quick and patient reply!<br><br> There is still one question: do you mean we only can define the multi-airnode using TRNSYS3D model? Can't normal TRNSYS thermal model or TRNSYS 16 work?<br>

<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Marcus,<br> It depends somewhat on what component you are using to model the attic. However, almost without exception, you need to define the slope and azimuth of the attic roof surfaces in your weather component (Type15 probably) and then pass the appropriate solar radiation outputs from that component to the appropriate inputs of your building component.<br>

<div bgcolor="#ffffff" text="#000000">Baboo,<br> I think that limitation is only in the Studio. TRNSYS components can have as many labels as needed. If you can give me a bit more information about what you are using the labels for, I might be able to suggest a workaround. For example, a lot of the TRNSYS printer components (Type25, Type49, Type65) do not need input initial values so instead we treat those as labels.<br>

Date: Wed, 27 Jul 2011 18:22:20 +0200<br>Subject: Re: [TRNSYS-users] Set 2 or more than 2 AIRNODES<br>Dear Wang,<br>
<br>
@ advantages of multi-airnode zones:<br>
Please refer to the 3D Building Tutorial, p.20: multiple airnodes are combined to one radiative zone (i.e. radiation through a window of the topmost airnode is not trapped there but also reaches the airnodes/walls below) whereas each airnode remains an own convective zone. Thus, thermal stratification, e.g. in an atrium, can be modelled.<br>
<br>
@ definition of a multi-airnode zone: in your 3D-model you have to define the adjacent walls between the zones that afterwards shall be combined to one zone as "virtual surface", they are not imported into TRNBuild (see explanation in the 3D Building Tutorial, p.15).<br>
After importing in TRNBuild, you have to move the airnodes into one zone as follows:<br>
1. open the Zone-Window for the airnode to be moved<br>
2. click the button with the bent arrow right below the name of the zone (see attatched screenshot) and a window named "move active airnode" will open<br>
3. choose the target zone, click ok<br>
<br>
You will notice that there appears a new button in the zone window named coupling (also see attatched screenshot). As there is no adjacent wall between the airnodes in the zone, this is the way coupling can be defined for airnodes in a multi-airnode zone.<br>
<br>
