[TRNSYS-users] Ventilation with controllable temperature

[Stefan de Kool]

Hello,

 

I want to implement a fan with an internal heat-exchanger used to warm the
ventilation air. I tried this with an auxilary node as follows: 

EN > AN = fan 

AN: Tset = desired temperature 

AN > thermal zone = opening (large crack)

 

For a validation run I choose Tset=Temperature of EN.

 

The problem is that with this, the zone temperatures are higher compared to
those w/o the AN. Does anyone have idea what could be wrong or is this not
the right way to implement this?

 

Thanks in advance,

Stefan de Kool
