Re: [TRNSYS-users] Turning ON-OFF Active system



Dear David,

Thank you very much for your reply.

However, I still would like to ask about one thing, since I am not much into this aspect. My goal is to control the flow rate of Active Layer (ceiling heating system) within the specified range of operative temperature. It means that I would like to switched off the active layer when the T_operative is higher than given value and then switch on again when the temperature drops below other value.

Thus, I wonder how is it possible to change variables that are defined in TRNBuild (flow rate) in TRNSYS? Do you have any experience with that?

Kind regards,
Lukasz

Ps. I am sorry if this mail comes twice, I had some problems with my computer.

Łukasz,

  There aren't controls available within TRNBuild. Make the inlet temperature and flow rate to the active layer into inputs and then you can use whatever controls you like in the Studio to turn pumps and other devices on and off and thus control the temperature in the space. Make sure to use a short timestep (1-5 minutes) or the building will not stay reliably near its set points.

kind regards,

 David

Dear All,

I am writing to you, since I would like to ask if there is a possibility to control the Active Layer - radiant ceiling heating system so that I could trigger it on\off whenever the airnode temperature is below or above the certain limit? Is there an option to do it in TRNBuild?

I would be grateful for any guidance.

Thanks in advance for your reply.

Kind regards,
Lukasz Watly
