Re: [TRNSYS-users] (no subject)



Sek,
  I am not sure that approximating an active chilled beam using the cooled ceiling model is correct. In my understanding, the cooled ceiling models a purely radiative device whereas an active chilled beam supplies a small amount of cooled, dehumidified air to the space through some induction nozzles that draw room air over a series of cool water pipes, cooling it and supplying it right back to the room. I would think that the more correct methodology would be to write a model of an active chilled beam itself.
Best regards,
 David

Dear Trnsys users,
 
I am trying to create an active chilled beam for a typical office space and I would like to clarify the steps that I have tried. Firstly, I created a new layer, which is the cooled ceiling, under wall type manager. After which, I added this new layer to the wall type( Roof). Lastly, I defined the cooled ceiling under each zone. If there is any errors or if I have missed out on any steps I would greatly appreciate any remedies provided. I would also like to find out if I were to model a passive beam, what are the different procedures in modeling. Thank you.
 
Best Regards,
Sek Jun-Yang
