[TRNSYS-users] Natural ventilation in TRNFLOW and HVAC components

[Adrien JEZEQUEL]

Hi Timothé,
When TRNFLOW works, ventilation and ventilation from Type56 are desactivated.
You can use Trnflow only when you need to calculate natural ventilation airflows and use Trnflow input to do this. This can be = 1 when you want to use Trnflow and 0 otherwise.
If you want to use Trnflow all the time, you may combine auxiliary airnode (with temperature of your air heater) and fan.
Best regards

To whom it may concern,

I am using TRNFLOW to model natural ventilation through some window openings.

However, I also need to include a air heater (Type663). How I would normally do this is by creating a new ventilation regime in TRNBUILD and connecting the air flow rate, temperature and humidity inputs to the outputs of the Type663.

I noticed that the ventilation and infiltration regimes defined in TRNBUILD seems to be ignored when using TRNFLOW. Can somebody confirm this?

If so, how would one proceed to model natural ventilation in TRNFLOW and the air heater?

I would be grateful for any support/confirmation on these issues.
