[TRNSYS-users] naturel ventilation

[Karol Bandurski]

Hi,

 

Honestly  firstly it should be stated that natural ventilation is so complex
phenomena that simulation of this issue is very difficult – there is a lot
of uncertainty (e.g. wind Cp value)

 

Using Type 56 (TRNBuild) you can only define natural ventilation
(infiltration, ventilation mode, coupling flow of walls).

 

To simulate natural ventilation accurately you should try to use CFD
software (Fluent/ANSYS, OpenFOAM-HVACTool, OpenFOAM-Helyx), there is
possibility to coupling this softs with TRNSYS e.g. type 101.

 

You can try to simulate it in more coarse way using airflow network
method/software – e.g. Contam, ESP-r or commercial TRNBuild plug-in:
TRNFLOW.

There is possibility to coupling Contam or ESP-r model with TRNBuild – see
type 97 and 130.

 

Contam is free airflow and contaminant distribution simulation software,
ESP-r is free building performance (both thermal and airflow) simulation
software.

 

Good luck,

Karol
