Could you tell me why don't we use ACM instead of conventional Air conditioner?
@kayzrx83 жыл бұрын
The energy required to provide the high pressure high flow air into the system would be way too much to provide without the use of a very large compressor and would be very inefficient. Aircrafts already have this source of air from the compressor stage of the jet engine. Noise would also be an issue.
@gasturbine1012 жыл бұрын
Does that really work? The plastic hoses look like they would blow off or melt with the bleed air temperature, there is relatively high pressures and flows inside an aircraft PAC??
@iatctechnicallearningvideo13232 жыл бұрын
This one is a mock up with fewer moving parts,not as robust as the real ACM, although those hoses seem more brittle than they actually are.

Sorry, but how does the air get cooled again? By extracting water and drying it out? Lots of talk about heating and reheating, but HOW does the air become cool?
@iatctechnicallearningvideo13232 жыл бұрын
When you compress, air heats. The air cycle machine does the opposite, it allows hot air to expand and cool in the expansion chamber. Before that happens the air would have already processed thru the heat exchanger that would make the first cooling impact over hot bleed air from the engine. Please refer to the lesson that talks about secondary heat exchanger. the ACM here is training model which functions on same basic principle as actual aircraft ACM except that it won't show you the actual engine attached to a wing.

This was a good example of an ACM layout, but not a good lesson on HOW it works. As he did mention (briefly) temperature does whatever pressure does... Px goes up.... Temp goes up. Px goes down... Temp goes down. Let's call this rule 1 The other important thing is that you can change temperature without effecting pressure much at all. Lets call this rule 2 Let's not get into the numbers, just imagine a scale from very low to very high. Air the plane is flying through...... px=v.low, temp=v.low Air goes into the engine compressor and into the bleed valve... px=high, temp=high (rule 1) Air passes through primary heat exchanger..... px=high, temp=medium (rule 2) Air goes through compressor of ACM...... px=v.high, temp=high (rule 1) Air passes through secondary heat exchanger.... px=v.high, temp=medium (rule 2) Air uses all that pressure to drive the turbine of the ACM, then empties out into a larger volume....px=medium, temp=v.low (rule 1) Now you have very cold air at a useful pressure. You can now mix it with hot air from the start of the cycle to get the temperature you want. It can now enter the cabin at a constant rate, you then vary the rate that it leaves the outflow valve and that's how you can adjust cabin pressure too! Hope that helps.

So this aircraft air conditioning system doesn’t require the gas used in domestic-like ACUs? Is it because of the constant ramming air that the aircraft is constantly receiving?
@michaelan96885 ай бұрын
This process follows the brayton cycle not the Carnot/refrigeration cycle - no refrigerant is required

@GNX1577 ай бұрын
I still don’t see where the system can cool cabin air much below outside ambient temperature when you’re on the ground. Like, in a car, I understand where the refrigerant goes from a high temp and high pres liquid to a low pressure vapor (that is very cold) at the orifice tube, and after. But where is something like that happening here?
@michaelan96885 ай бұрын
You are overthinking it. When on ground the exact same process occurs but the hot high pressure comes from the APU instead of the jet engines
