Heating & Cooling system

Hi,

I would like to know, how could I change the capacity of heating & Cooling system in DB. I have a case study room and I assumed the
Cooling set point temperature 26.00 (oC)
Cooling set back 29.00 (oC)
Heating set point temperature 19.00 (oC)
Heating set back 12.00 (oC)

typical winter and summer design week simulation show me the internal, radiative and comfort temperature is lower than temperatures that I assumed above. further more I defined HVAC systems as Simple, 3-Autosize.

what should I change reach the setpoint and set back temperature, and is it possible to change the system capacity.

From your description it looks like you are using Operational temperature as a temperature control in your simulations. If that is the case you can change it to Air temperature in model options (Simulation tab)/Calculation options and you should get the desired setpoint temperatures.

You can input the HVAC system capacity at zone level by selecting the HVAC Sizing option as manual in the program option (please see the figure).

I hope it helps.
