[EnergyPlus_Support] How to Control LowtemperatureRadiant system and typical HVAC system through external algorithm? [1 Attachment]

["m.waseemahmad@xxxxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Hello All,

I want to control LowTemperatureRadiant system by using an algorithm e.g. I want to use Model predictive control. I know EnergyPlus can control LowtemperatureRadiant based on different temperatures e.g. indoor air temperature, MRT, outdoor air temperature etc, We also have to define a throttling range, meaning if the set-point is 15 degrees and throttling range is 2 degrees C then there will be no water flow where the temperature is at or above 16 degree and maximum flow at 14 degrees and so on. My question is can we implement our own control algorithm so that we specify flow rate at a given time step meaning the control algorithm will pass values of Water flow rate to EnergyPlus? the same goes for a typical HVAC system? How can we specify Ts AND ms (Labelled in the figure) from outside EnergyPlus. I more interested in LowTemperatureRadiant systems (top figure). Please see the figure below, where I have tried to draw both systems.

The idea is same as you do for optimization? Any idea, how to do this?

Thanks

Kindest Regards

Waseem
