[TRNSYS-users] Qheat - calculation



Dear all,

 

I need your help.

I have simulated with TRNSYS a small quadratic office building.

One of my Outputs in TRNSYS is the heat demand (Qheat).

 

Can someone explain me, how TRNSYS calculate the heat demand (Qheat) ?

 

If I calculate the heat demand with a “static calculation tool” or per hand, then I have a difference of 40 percent to the dynamic result of TRNSYS.

 

Are only the dynamic effects (e.g. storage capacity) the reasons? And are 40 - 60 percent realistic

 

Thank you for your answers.

 

Best regards

 

Andreas
