Hi all,

I have to size Fan coil units in my model with known cooling powers.

But on EnergyPlus/DesignBuilder, we can only specify maximum cold water flow.

I've checked the Engineering reference of EnergyPlus (pasge 289 - Fan Coil Unit Sizing Formula (1257)) and they give the formula linking the two entities. However, it is unclear what are the other different parameters involved, didn't find any nomenclature explaining them (quite annoying actually), especially the DeltaTloop,des.

Can someone help me with it?

Thanks in advance
