[TRNSYS-users] CO2 coupling with Comis and trnsys (2)

[danny roelofsen <dannyroelofsen@gmail.com>]

Dear Trnsys users,

 

I'm making a model where i'm coupling Comis and Trnsys to make it possible to control (turn on and off) the ventilation with concentrations of CO2.

 

I have a CO2 source (I assume this source has to be given in Comis in each individual room). I used a type 14h controller which gives out a value 0-1 to control wether the pollution source is on or off. I connected the actual factor of type14h to the "actual factor for source with schedule". In the results I can see that the concentration is higher in the periods the source is active, but it seems it is not increasing over time when the source is turned on. It seems like the source in Comis is regarded as a concentration in/by Trnsys.

 

I attatched my files of Comis and Trnsys

 

Does anyone has a solution for this problem?

 

Thanks in advance,

ps: I need an increasing concentration of Co2 in order to be able to control the ventilation system, which i'm trying to control with type 2d. (comparing the concentration of CO2 with the upper and lower dead band). If there is a better solution for this i'd be glad to hear about it.
