Air Exchanges

[iwmech]

A quick one, does anyone know what l/s.m²fac mean as a unit for air exchange flow rate?

Thanks in advance.

That just means that the flow rate is dependent upon the floor area of the room the air exchange is attached to.

So if you have a template with an air exchange set at 0.5 l/s.m2 and you apply that template to a room with 50m2 floor area, the flow rate for that room will be 0.5 x 50 = 25 l/s

Hi CP,

Thanks for your response. Thought about it some more and I suspect that it actually means L/s per meter squared of facade? There is another option L/s.m^2 and I guess this is what you suggested.

Thank you.

Ah yes, I think you're right. That one is quite a new option I think but handy.
