I am looking for some numbers regarding the air condition in different jet aircraft.

How much air mass and/or air volume is blown into or cycled through the airframe per minute/hour?
Is there a difference between air/ground (pack low/normal/high flow)? How much?
How much air mass or air volume is supplied as fresh air and how much air mass or volume is recycled (through recirculation fans)?

Thanks for your help!

I'm pretty sure this has been answerred before on these forums.

In the A320 family the nominal normal flow is about 1 kg of fresh air per second.
High and low flow are 120% and 80% of that nominal flow, respectively.
