Well there is kind of a jet engine inside... These chillers use centrifugal compressors and they give off that sound they look very similar to the impellers of jet engines.
@@BritishEngineer Here's an explanation for the humming sound you hear before the first water pump starts up (timestamp 3:36.) Initially, this humming isn't coming from the motor, but rather the other motors in the area. This is due to them being run off of an inverter. The odd frequency (360Hz) is due to the power supply of the inverter, which uses a 3 phase diode bridge rectifier., which produces a ripple that has a frequency of six times line frequency (60Hz in this case.) Even with good filtering, some ripple still gets through to the motor. Once the water pump starts (with that hilarious "twah" sound), the 360Hz hum gets slightly louder because the motor has been energized. I only know the sound because I have seen many videos of these types of motors starting, and have heard them running at theme parks, to drive roller coaster chain lift hills. Hope this helps
That's what the pumps I used to work with doing irrigation on a ginger farm! Theyd speed up really quick then pause for a millisecond and then Just scream at you while your in a rinky dinky old 2x2m shed praying nothing like spontaneously Combusts due to the immense sound 🤣🤪

If you look closely at the motor when it starts, The mounts for the motor support is heavily rusted and the motor moves which causes the tension on one fan becomes very loose and the belt slips.
That’s not a stupid question haha 2 phase was a power service in the late 1800s early 1900s, to aid single phase motors starting up before 3 phase power was a standard. Some building has not updated and still require 2 phase service. so the building adds a “Scott-T Transformer that changes 3 phase into 2 phase and wiring backwards will turn 2 phase into 3 phase. Yes the phases are 90 degrees and has their own 2 conductors. (4 conductors total)
@@coastersaga I am not veey convinced by the 180 degree apart part. I don't see how two inductors that are inline with one another can create a rotating magnetic field. Alternating yes, but not rotating.
@@baconshark8067 So any motor running on split-phase would be electrically very similar to a single phase (capacitor start) induction motor, requiring a starter winding, centrifugal switch, and start capacitor to give it the kick it needs
Outdated type of power feed that some parts of old cities, old towns still use that want to keep historic buildings “as is” that uses (4) seperate feed wires instead of (3) power wires for 3 phase or (2) power wires (with a neutral) for single phase
fascinatingly crazy what people put online for videos ... and even crazier is why people watch something like that ... we like that
Whoop
Haha true that..
At least these types of videos are not that clickbate garbage lol
@@NickSilcox3 this is far better than that
HV/HC Harmonics and transients noises are like relaxing music for some of us…..🤭🤭. 👍👍
awwww that old quincy compressor, cant beat those with the air unloader soft start. Theyll last forever (my old shop had one I rebuilt from the 50's)

yo you right that the chiller sounds like a jet engine
0:53 I think that’s the most epic motor startup I’ve ever heard!
I guess I'm kind of off topic but do anybody know a good place to watch new series online?

wait what? you found one just on the side of the street? wtf
This should be marked under most satisfying video! Great video buddy!
Chiller one sounds so cool!
One of those chillers sounded like a jet engine.

the belds on cooling tower fans have a tough job
“Twah” - water pumps
If the fans at 0:43 and 1:43 like to smoke belts perhaps you should put a VFD on for softer starting
The fan runs 24/7 and the only time it shutdown is when maintenance is done to the air handler and It only smokes old warn belts
Wooow. Totally amazing electric motor up Spinning sounds. Pls. More videos.
Great video.
Even single phase muffin fan motors sound like this on startup.
0:54 the size of a school HVAC:
4:33 *the belt literally did a burnout*
The third one with new belt sounds like a jet takeing off lol
ahh Music to my ears
1:41 sounds like a tire screeching
Exactly
2:04 sounds like my air conditioner
cool i guess
Who found this in recommended
time to dont play fortnite
Awesome!!!
2:35 you can hear the sound of the PWM from the VFD motor whatevers
Nice !
0:36 the belt is slipping bad
0:05 wow that's a old blower
It has paddles
It's from the '40s
I take it you work on these big motors for a living?
TrainTrackTrav close, I work in HVAC in commercial and industrial applications
This is awesome.
5:20 why the fans are going different the left is fast but the right is slow?
If you look closely at the motor when it starts, The mounts for the motor support is heavily rusted and the motor moves which causes the tension on one fan becomes very loose and the belt slips.
even though i can hear the slippering sound
Are all to the belts replaced yet? Remember to show me the video of the belt replaced.
Make more like this please
ok, dumb question: where (unless you generate it yourself) and why (rather than 3) do you get 2 phase power? are the phases 90 degrees?
That’s not a stupid question haha
2 phase was a power service in the late 1800s early 1900s, to aid single phase motors starting up before 3 phase power was a standard.

What is this for what is your job
What is that sound when its started up and why is it so good
The sound you hear is the vibration of the motor windings as the inrush current rushes through, 7-10x it’s rated current draw
Water pump: TWAAAaaa
Water pump: TWAAAaaa clunck
Why do water pump motors sound like that, compared to fan motors?
@@coastersaga because they speed up faster and run at a higher RPM i guess
Tame is a good thing
who found this and realised its not public ? haha
Sneak preview haha! It’ll be public soon!

Whats that tiny little motor at 2:00 used for?
Eleavator Cooling
That makes sense @Mateo C
@@chrisbrasher6177 it’s just a wild guess but I’ve seen that in a elevator once before but I’m assuming
It's just the duct fan there's actually two motors
@@jaedenspider877 ohhh so that’s the echo I’m hearing
What is that supposed to be for😅❓
A 2 phase motor? What are you talking about?
It’s 2 phase, 4 or 5 wire setup. Please read description for what a 2 phase motor is
2 phase power still exists (except now it's called "split-phase,") and the phases are 180 degrees apart.
@@coastersaga I am not veey convinced by the 180 degree apart part. I don't see how two inductors that are inline with one another can create a rotating magnetic field. Alternating yes, but not rotating.

@@coastersaga in my opinion, it is still single phase.
What is 0:29 motor for?
Air Handling Unit.
I want to know what those fans are for.
cooling towers.
Hehehehe motor go woooOOOOP
