[TRNSYS-users] Storage Tank 3 In/Outlets

[Ökoplan Frau Settler]

Hello TRNSYS users,

 

I am searching for a thermal storage tank model (vertical, cylindrical) with
three inlets and three outlets, similar to Type 4 or Type 60. 

Where can I find one? 

 

Best Regards,

 

Sarah

Paul, 

The easiest way is to use two zones, but if the thernostat is in the hall,
maybe you should include that zone as well? You can also consider using
CONTAM or COMIS to calculate air exchange between the zones, although this
makes it more complicated. 

You can have one emitter for each zone. To represent parallell heating
circuits, just split the total flow from the heat pump using a diverting
valve component (Hydronics library) into one stream for each emitter and
then, after the emitters, combine the streams again using a mixing valve
component and connect it back to the heat pump. 

Kind regards, 
Knut Erik

[TRNSYS-users] How many zones?

 


I am modelling a 2-floor domestic property.  The 2 floors are connected by
an open hall, stairs and landing.  A thermostat is located in the hall.

A single heating system (GSHP) will need to supply heat to both floors
(under floor heating or low temperature radiators.)

What is the easiest way of modelling this;  I'm thinking:

1) Use 2 zones;  One for upstairs and one for down stairs.
2) Each zone has an emitter.
3) Each emitter is a load on the same heating system.  Is it easy to
represent parallel heating circuits from a single heat source?  What
components should I be looking at?

Any comments welcome. 

Thanks 

Paul
