Chilled ceiling information

Postby dylan.debbi » Wed Jan 02, 2019 2:19 pm


In the 5th version of Design Builder, it is possible to enter a heat flux in W of the chilled ceiling. Could you please tell me what represents this heat flux ?
- In which temperature condition has to be given ?
- Is it a good way to modelise a chilled ceiling like this when the manufacturer provides us its power ?

Thank you

There are 3 ways to define the cooling capacity of the chilled ceiling.

1-Design capacity (W)
2-Capacity per floor area (W/m2)
3-Fraction of autosized capacity

For more information about this component see the Program Help link below: ... t_Flow.htm
