I am little confused about creating (wall fans) in energyplus , i mean ordinary fans that doesn't attached to any HVAC system or something . i need to use them in cooling a space in a certain time . i found ( ”Fan:SystemModel”, Fan:ConstantVolume, Fan:OnOff, Fan:VariableVolume,) but they require inlet and outlet air node name which make me think that these groups are only for HVAC system fans and there is another way to simulate these ordinary fans. if these are the only way to create them i want to understand what should i do about inlet and outlet air node name input

thanks in advance

If I undertand correctly you mean a simple fan that recirculates air in a space. A simple wall fan cannot cool a space, instead it is a thermal load. However, a fan can contribute to thermal comfort but I am not sure if this is your question.

You could also create a HVAC air loop with just the fan and a 100 % outdoor air system and a zone and then schedule that somehow so it brings in unconditioned outdoor air when you want it.
