[TRNSYS-users] Need in monitoring the temperature in type 56 model

[David BRADLEY]

Rakesh,
   It looks as though you are passing some incorrect variables back to 
the building model and that the variables you are passing (T_HEATING, 
T_COOLING, and RH_COOLING) are defined in the building but aren't 
actually implemented in your zone. The inputs that you need to pass from 
the furnace model to the building model are the furnace's outlet air 
temperature, RH, and flow rate. You will need to open TRNBuild and 
define a VENTILATION type in your zone. A couple hints:

1. Specify that you are going to provide air flow rate as a mass flow 
and change the flow rate from a constant value (the default) to an 
input.  Give the input a name like MVNT_55FC41
2. Specify that you are going to provide the temperature of the 
ventilation air as an input. Give the input a name like TVNT_55FC41.
3. Specify that you are going to provide the humidity of the ventilation 
air as an input and as an RH (which is the default). Give the input a 
name like RHVNT_55FC41.

When Type56 talks about ventilation, it means a stream of air, not 
necessarily the zone's fresh or outdoor air as is sometimes traditional 
in the US.
best,
  David
