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
