High temperature radiant systems

Hi to all,

I am new to Ironbug. I was wondering if it is possible to model electric high-temperature radiant systems such as those commonly used in high industrial facilities that cannot be heated by other means:

I am quite confused about how to calculate heating consumption with this type of system.

I really appreciate any help you can provide.

Hi @Julioamodia89,

I guess you can use ZoneHVAC:HighTemperatureRadiant
Group – Radiative / Convective Units: Input Output Reference — EnergyPlus 23.2 (bigladdersoftware.com)

Hi, I am using this component and trying to connect a fixed interval schedule as the heating set point temperature schedule and getting this error…

  1. Solution exception:Failed to set Heating Setpoint Temperature Schedule! Please double check input data type, or typo!
    Detail error message:
    Object must implement IConvertible.

Hi @Nicholaskerr
It sounds like you did not set the correct data type for the schedule. Meanwhile, don’t forget to set the minimum and maximum value for your new schedule, as the defaults are 0 to 1.

Hi @MingboPeng I am seeing that the ironbug schedule allows a maximum of 24 values for temperature setpoints. my fixed interval schedule has 8760 values based on outdoor temperature. At the least i would want a minimum of 365 temperature set points.

could this be the issue?

as you can see i have set the data type to temperature. I’m not sure what you mean by setting a min and max as there is no option for that within the fixed interval schedule.
