[TRNSYS-users] TRNBuild / Type56: Documentation on handling custom inputs

Thu Sep 17 04:12:28 PDT 2009

Paul,

When you specify a heating type in TRNBUILD, you simulate the building in 
Energy Rate Control. This is useful for dimensioning equipment as you can 
output the heating load from the building given a specific set 
temperature. When you actually want to simulate operation of the 
equipment, like a GSHP system, you should use Temperature Level Control 
instead. Then you should turn Heating off in your building zone, and use 
Ventilation (if heat is delivered by air) or Gains (for example radiators 
or heat pipes) to couple your heat source to the building. See this 
tutorial: 
http://sel.me.wisc.edu/trnsys/downloads/tutorials_and_examples/tlc_tutorial.pdf 
for an explanation of using Temperature Level Control.

Hope this helps,

Knut Erik

Thanks for your quick reply Olivier.

The following paragraph from 06-multizonebuilding.pdf confuses me:

"The heating requirement of any zone subject to idealized heating control 
can be determined by specifying a heating type. If the heating equipment 
is modelled external to the TYPE 56 component, the heating type should not 
be used. Instead, VENTILATION AIRCHANGE, TEMPERATURE and HUMIDITY should 
be defined as INPUTS, fed by outputs from the conditioning equipment 
component(s) or the supplied heating power should be defined as CONVECTIVE 
and RADIATIVE GAINS. The specification of a heating control is optional 
and the default setting of the heating control is off."

So I do use the Heating Regime to couple the heat source:  I just have to 
understand the radiative and convective split of my emitter?

What role does the ?set temperature? provide?  Zone temperature is an 
output to my simulation and it is the simulation that controls whether the 
emitter is receiving heat or not.

Thanks
Paul

Paul,
After having created your input, you can use it in several screens in 
trnbuild, it depends what you want to do. 

Cordialement,

Olivier Guillemot

inputs

Can anybody point me at documentation or examples, which show the handling 
of custom Inputs to Type56 in TRNBuild.

I've followed 06-mulitizonebuilding.pdf.  This describes how to create a 
new Input field which will appear in the interface to a Type56 instance 
within the Simulation Studio but it does not show how you use it for 
anything within your building model once you have created it.

I'm trying to connect a heat source ( from emitters of a GSHP system ) to 
the described building.

Thanks
Paul
