[TRNSYS-users] RE : RE: Room temperature control

[bihr yves]

Thanks for your help, but my problem is not solved.
   
  J. Cramer Silkworth, you said: 
  Type 14 has two outputs - the first is the average value of the function, the second is the instantaneous value at the end of the timestep. It seems like you're using output 1, try using output 2 connected to type 56.
   
  The problem is the same when I use an equation to define the value of "set temperature".
  What I do not understand is:
  I define (with an equation) the same schedule for heating and ventilation.
  The equation outputs are, for exemple: 
   
  Hour       Air temperature        Air change (vol/h)
  6                      16                                0
  7                      16                                0
  8                      20                                5
  9                      20                                5
  10                    20                                5          
   
  But the outputs of Type 56 are:
   
  Hour       Air temperature         Air change (vol/h)
  6                      16                                0
  7                      16                                0
  8                      18                                5
  9                      20                                5
  10                    20                                5
   
  So air change is ok, whereas air temperature is wrong during 1 hour
   
  Does anyone has an idea about that? Thanks by advance.
   
  Best regards,

  Dear trnsys users,
   
  I'm a new Trnsys user and I'm the only person who uses it in my company. So my question is very simplistic.
   
  It concerns "room temperature control". I define "set temperature" with the schedule editor included in Trnbuild, or with Type14 or with an equation. But temperatures given as outputs by Type56 do not correspond to "set temperature", when the value of "set temperature" changes.
   
  For an exemple, when "set temperature" values are 16°C at 8:00 and 19°C at 9:00, the temperatures given by Type56 are 16°C at 7:00, 17,5°C at 8:00 and 19°C at 9:00.
   
  Does anyone has an idea about that? Thanks by advance.
   
  Best regards,
  
  Yves Bihr
