Re: [EnergyPlus_Support] Fan Coil Unit - Convert cooling power capacity to maximum cold water flow



Nassim,
You can edit the fan power by expanding the zone HVAC, then editing the fan object.

Fan sizing is also affected by the sizing temperatures in the HVAC Zone Data screen.

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


Best Regards,
