You seem to indicate that the Ram air goes into the Air Cycle Machine, this is a common mistake. The Ram Air merely goes through the Heat Exchanger to cool the Bleed Air from the Engine, which does eventually go into the ACM. Also, I believe that there is a second Heat Exchanger after the cooled air goes through the ACM Compressor before entering the Turbine.

I completely forgot the pack air temp was manual only on the 200s. I once had a 200 pilot tell me regulating the air temp made up 80% of his work.

The on-wall model is very good, helps understanding, but the technical accuracy, narration, music gets solid thumbs down from me. Narration is confusing and factually wrong in places. (eg, the wings anti-ice air does not come from the PACK outlet as implied, it is not even close, it doesn't even come from the same bleed air -- 14th stage vs 10th stage air. Oh, also, the CRJ does not have 'de-icing system', only anti-ice). Another criticism is the use of Fahrenheit. Everything else in aviation is in Celsius, why use Fahrenheit. Why two or three different narrator?

Bernard Goh deice is active and anti ice is passive. CRJ 200 does use compressor bleed air that flows thru perforated tubes on the leading edge of the wings and empennage. Whether that meets the definition of anti or deice I’m not sure. You are correct that anti ice does not pass thru the PACK.

The CRJ does not heat the empennage. This video is about airconditioning, meaning only 10th stage bleed air. To throw 'anti-ice' in there is wrong and misleading, anti-ice uses 14th stage bleed on a completely separate circuit.

So clearly no gas freon is been used,like Aircondition system on the ground,Aircraft take advantage of the super cooled air in the atmosphere in flight levels (above18000)

Nope, the compressed Air coming from the Engine is at about 300°, this system also works on the ground on a hot day. This system uses simple Thermodynamics to cool the air...compressing air makes it hotter, decompressing cools it, strategically placed Heat exchangers and regulators produce the desired temperature and pressure.

Very informative but ⁰F? I had to stop and look for a more relevant video that used globally understood S.I. units . . .
