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

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,

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
