Adding fans that improve air circulation into rooms without adding an inlet T
 
Hello,

I am working on a problem where I have a room with an airconditioner and various heat sources. I applied a volumetric heat generation term to the heat source and have an inlet velocity from the air conditioner at 273 K for cooling.

I want to add a few additional fans into the room that function to improve the cooling in the room.

When I set the inlet velocity of the additional fans, it is set at 300K which I believe messes up the air conditioner cooling of the room and components.

How do I make these fans just add circulation into the room?

What you want is not a boundary condition but a momentum source

Thank you for your response. I was wondering how I can specify this momentum source into Fluent in order to simulate a fan.
