Load Duration Curve

A heating load duration curve is a chart which displays the hourly heating power demand over the calculation period.

Room


Defines from which room you want to view the Load duration curve

You can view only one room at a time in the graph.

NOTE: Only the calculated areas are displayed. If the desired room is not present in the list, then it has not been calculated.

System Type


Here you choose what type of generator you want to show on the load duration curve:

      Cooling. This is a blue line and represents the required cooling capacity.

      Heating. This is a red line and represents the heating capacity.

      Heating and Cooling. Both the heating and cooling capabilities are visible.

HVAC Part


Here you choose whether you want to show the area of a room, or the entire building on the load duration curve:

      Local relates to the power required to heat/cool the room;

      Central (air handling) to the total power required to heat / cool the air (the ability of the AHU);

      Local and central. Subject the total power to heat/cool the entire building.

Power Limit


With the heating load duration curve you can set the limits of your heating and/or cooling generator.
