Re: [TRNSYS-users] Temperature and %RH setpoint TRNBUILD

[David BRADLEY <d.bradley@tess-inc.com>]

Gary,
  Defining your setpoint as a SCHEDULE in TRNBuild simply allows you to set a value that depends upon the time of day. Defining your setpoint using an INPUT allows you a good bit more flexibility. You could define your equation as follows:

Tset_heat = 24*occ + 12*(1-occ)

occ would have to be defined in another equation or perhaps a Type14 forcing function to have a value of 1 when the building is occupied and a 0 when it is not occupied.

Best,
 David

Hi,

I trying to calculate the cooling demand of my office building in TRNBUILD and would like the cooling demand to response according to my occupancy schedule(less cooling at night and more cooling at day). I try to define the set temp at the cooling type by i not sure which one should i use (schedule or input?) And also the equation behind it, because when i enter like for instance 24degree(set temp) *occupancy schedule+0, i would get 0 degree when there is no occupancy.

Appreciate your kind assistance on this

Gary Kum
