- In this video we look at the air conditioning system in an aircraft. We see why this system is required, what is an air cycle machine and how cooling is achieved in this system.
The different components of this system and how these components function to provide cool conditioned air is explained here.
Thank You!
Glad to say I currently overhaul these cool machines :) for the Dash-8 and CRJ series. not exactly the coolest feature of an aircraft to work on but someone's gotta do it
Wow! That's awesome!
It would be the coolest lol but maybe not the most fun lol. We all appreciate it though
Unreal how complex these machines are! Thanx
Yes They are
These are just loving videos...please continue whole aircraft engine series

Excellent work👌
just i have a question about temperature in the outlet of the primary heat exchanger and how it can be calculated
Thank you for your answer ❤❤
not sure of the calculation part
Your is very good
Thank you! Do Check out my other videos as well!
Good video. What about air conditioning when aircraft is taxing?
Thanks.
The engines will supply air to the Air Cycle Machine, which will provide cool air.
Such a great a video
Thank you! Check out my other videos as well!
Yeah sure
PERFECT. THANK YOU!
Welcome!
beautifully explained
Thank you! Do Check out my other videos as well!
Thanks. Good lesson.
You are welcome!
Thank you! Now back to AE
That's great1
Can you explain ac works in turboprop?
Very good explanation, but what happens when the outside temperature is hot? How air conditioning system works while the plane is on ground?
There may be external air conditioning units which would supply cold air directly to the mixer unit. Or bleed air is supplied to the Air Cycle Machine to achieve cooling through air expansion in the turbine
Is that the reason it looks like there's an outdoor unit on the jet bridge/passenger boarding bridge? is it because it's giving cold air to the airplane?
Amazing video !!!! this is how my brain works I gotta see it unfortunately... How many temperature controllers does an aircraft have?
glad i could help. controllers depend on the size of the airplane
Sir do aeroplane still gets the air in... Incase ac stops working though the temperature inside may get high... And the plane is either on land or in air ..do these inlet still supply the outside air without any cooling or sucking of air inside?
Well done!
Thank you!! Please do check out my other videos as well!
Superb video
Thank you! Do check out my other videos as well!
Well explained.
Thank You!
Thanks for this great explanation.. keep it up sir.. is this on A320 air conditioning system? Thanks again 😊
Yes, it is
Interesting, if I’m understanding it correctly there is no refrigerant like in a standard air conditioner, air IS the refrigerant?
Make one video about vapour cycle air conditioning system
Sure. Will note it!
Another good video
Thanks again!
Thank you
You're welcome. Do check out my other videos as well!
I learn basic from this video I got 5 mark out of 5
The No Bleed system is the future.
The 787 has it.
All aircraft must now follow.
It is a no-brainer.
Yes. A glimpse of the future!
Good one
Thanks
Excellent
Thank you! Cheers! Check out my other videos as well!
mükemmel bir annlatımm
Could you please make a vdo on vapour cycle Air conditioning system?? Plz!
Have noted it. Will make one on VC Air Conditioning soon!
I thought that air conditioning in planes use refrigerant, but i was wrong. thank you very much for the great video. Very well explained.
Thanks! Check out my other videos as well!
Me too think there’s refrigerant in the compressor…thank you 😊
there is a refrigerant
the air is the refrigerant☠️
Great video! Had a question about whether there is a condenser because a few of the AGU diagrams we are covering in my class have a condenser.
That's a different kind of air conditioning system, called as the Vapor Cycle Machine.
Thats for reciprocating engines
I would like to thank but , but I cannot. You are missing to explain some major points. one of them, where the energy comes from to rotate shaft? How the turbine expansion gives enough torque to compressor? Can you explain from the aspect of conservation of energy and thermodynamic laws?
¡Excellent!, thanks
Glad you liked it!
Thank you.
You're welcome!
Can you also provide detailed presentation about VCM (also a type of air conditioning in aircraft)
I have noted it down. Will do something on it soon.
Allay sellim timmek :)
thanks
Welcome
I don't know from which aircraft is this air-conditioning system but on 737 is for sure air in primary heat exchanger not cooled from fan air. Fan air is part of pneumatic system. Fan air is cooling the supply of bleed air to air duct in pylon trough pre-cooler.
I will need to check the Air Conditioning System on the 737, but the basic concept would be the same for the Air Cycle Machine.
Sorry, as my experience, on a 320 the water seperator is after the compressor and before the turbine of the acm is it correct?
Its just after the turbine as that's where the condensation happens!
Pleasant 💯❤️❤️❤️
Thank You!
thank you for the great explanation. but how does the volume of air remain constant in the mixer unit and in the aircraft? air is just coming in, but i dont see where excess air is supposed to go out from.
From the mixer unit, air is continuously supplied to the aircraft cabin.
I mean, if you follow the dark blue arrows in the diagram @4:00, the cooled air from the turbine is fed into the mixer unit, and into the aircraft. But there's no air coming out of the [mixer unit + aircraft] system. So where does the warmer air from the cabin go to?
@@estherauyong4941 Some of the air flows back into the mixer unit after filtration and the remaining air is let out by the outflow valve!
@@JxJAVIATION I see.. Thank you for the explanation :) 👍
could you please explain what is the filtered air you mentioned in the end of the video? Is it the old air already remain in the cabin before the new air delivered? Thanks a lot.
Most of the air from the cabin is vented out. Some of the air is recirculated through different filters which is called as filtered air.
the music in the end freaked me out lmao
apologies!
Good video. What about the "bypass valve"? Where is it located?
Thanks.
Thank you! Check out my other videos as well! The bypass valve comes between the compressor and the turbine of the air cycle machine.
@@JxJAVIATION Thanks! Surely, I will check.
is bypass valve the thing that controls how warm the air is
Hi Sir, I Am doing a work for my Bachelors Degree, and I need to talk in my final paper about this system. Is it possible if you could send me a link where I can get access this information. Thank you
Check out the FAA handbook for Pilots on the Aircraft Systems!
very nice. what do you use for your illustration software?
This is MS Whiteboard!
3:46 What is filtered air taken from the aircraft? I mean i couldn't understand this part. Great topic by the way.
Air that is inside the cabin is filtered and mixed with air from engine, cooled then pumped back to cabin again
@@henrytsao1 Thanks!
@@henrytsao1 why does the air inside the cabin needs to be filtered again?
The air from the cabin is "impure air" so needs to be filtered for recirculation
@@JxJAVIATION I think that’s where the HEPPA filters are fitted
Hello,
I am a bit confused, where are the packs? aren't they used in air conditionning system? thanks
The unit which has the air cycle machine is called as the Pack!
How do you make this animation? Which software is used? Pls share
Thank you but there are some missing parts, like condenser and reheater also there are some mistakes in your graphics like cooling air for PHC and location of water separater. Good luck
Think you are referring to the air conditioning system which has a vapor cycle machine. The system which I have shown is the one with an Air Cycle Machine, or ACM.
All good but music in the end destroy ears
Apologies for that!
abiii böyle bir şeyy yokk
So it means the working refrigerant is air
yes!
lol so weird
I guess this is because outside air is cold enough that it doesn't need latent heat of evaporation to help the movement of the heat
HOW THE RAM AIR GET COOL AIR WHEN THE AIRPLANE IS ON GROUND?
I AM STUDING FOR MY A&P LICENSE
They use APU
Using APU or external bleed air!
I think the reason for that is also the reason why you see air conditioner outdoor units in jet bridge/passenger boarding bridge
building air conditioning system: we use a refrigerant to cool the air
airplanes: the air is the refrigerant
Yes and lots of cold air is readily available to act as refrigerant!
Reheater & condenser?
This is the Air Cycle Machine Type of Airconditioning System
Sir you didn't mention the "Reheater" and" Condenser"of the A/C system
This is the Air Cycle Machine type air conditioning system!
@@JxJAVIATION Doesn't matter. Even in this type there is reheater and condenser.
Hello I am working B737-700.
One problem our plane during on ground in the Cabin very hot not cooling. We cleaned water separator coalescer bag. Still hot in Cabin. After take off normal cooling cabin.
Checked the coolant quantity?
@@JxJAVIATION can you please send me instructions 🙏
@@bayarmagnaijaranjil9391 Please use the manuals for exact procedure
You probably have a worn out air cycle machine. The acm is pushed harder on the ground than in the air because on the ground the outside air is warmer than at altitude.
Aircraft in air ,ram air not provide in heat exchanger then what to do
The cooling would only be achieved by the air passing through the air cycle machine.
Excellent presentation of a complex system. However there are still some downstream portions that need clarification. The kind of filters used to because in the cannibals HEPA, and not very effective for microbe filtration, The air flow is also very poor because it is a vortical flow not laminar or horizontal There is recovery time with open aircraft when boarding and unboarding. Over all while effective cooling system for comfort it is not very specialized in in microbe or viral prevention which still makes flying unsafe..
Thank you for the information!
where is the condensor in it
You are referring to vapour cycle machine type of cooling. I have given a Air Cycle Machine Cooling!
How can I hear it Bengali
Dont think that option is there!
You forgot to add humidifier at last
I will make a video on Vapor Cycle Type Air Conditioning system which will include this!
@@JxJAVIATION alright thanks 😊
🤔🤔🤔🤔🤔🤔
Where are secondary H.E & reheater & condenser......?
💔
That's a different type of air conditioning system.
lol why won't other air conditioners use this principle of using the air itself as a refrigerant
oh wait it needs already compressed air to compress itself
haha guess you answered your own question!
The video is not accurate at all, and the system does not explain all the components of the system, and some components are not related
You are referring to vapour cycle machine type of cooling. I have given a Air Cycle Machine Cooling!
You're right. For example the water separator is upstream the turbine and not downstream. Also the second stage heat exchanger and the trim air are missing. The ram air is used to cool down the heat exchangers.. it's a bit a disaster 😂
