Ed, thanks for the video. I have this compressor in my home unit here in Phoenix, it is 21 years old and I'm afraid is giving up the ghost. After watching this video I know EXACTLY what is happening to mine. Sometimes during a run , you can hear the compressor sounds like it slows down and starts rattleing or as you say scrambleing , if I allow to continue, the comp heats up and and shuts itself off. After about 30mins it will come back on and sound right. This is a heat pump so it is in use all year and is very busy here as it was 46c here yesterday, we are in cooling from about april through oct-nov. hopefully the old girl will hang in whilst I shop out a new unit, thanks again for the in-depth video, I like your new Merc by the way , its abig jump from little car ! Scott
Great Vid! As well as Ac and blowing stuff up, i also really enjoy your engine projects and am looking forward to seeing the big generator finally going.
I was always curious as to why a compressor made the metallic buzz vs the typical hum of a fan motor. Now seeing how those metal plates / pistons move explains that. they're just going at high speed under normal operation. Thanks for the video, even though I've come across it years later. I recently had to have my apartment's heat pump replaced, the unit that was here, was installed in 1994. Anyway the other night when the AC came on, the compressor shut off, came back on and blew a big hole in the side of the coil, and all the Freon escaped in a big woosh. The unit had been trying to die the last few years, and they tried to milk it along as to not to go through the cost of a new one as long as possible. It had gotten really loud too, it sounded like it could go at anytime. The new one is much quieter, even inside as well as out.
Those things are quite a mechanical marvel inside, its seems a lot more complicated then just using pistons and cylinders, not compared to something like a radial aircraft engine of course. The scrolls themselves look like something you could use in a piece of ornamental iron work like a fence or a railing.
I have a 5 year old 2.5 ton that knocked after 3 minutes of start up for 10 seconds today.Had to shut breaker off to get pump to start twice yesterday.Today it’s cycling fine except wondering about the 10 second knock? Cool video.
Thanks for the video, I was wondering what was inside one of these. It doesnt seem like a whole lot can go wrong, though I do wonder what damage was done to mine when the tech over charged it and that compressor hammered LOUD, still kinda runs but my ac doesnt work well.....
Very informative video, looks like Copeland should pay for your video or maybe they are not too keen on giving away their design secrets. Definitely agree that the floating seal and pressure loading on the fixed scroll is an ingenious design feature. I would assume that the floating seal is last part of the Copeland compressor that ever fails in service. The video now explains why my Lennox condenser with a Copeland compressor does not use a starting capacitor (only uses a run capacitor) like some competing condenser units.
Thanks for sharing the videos. I have a Danfoss model 120U1908 but I didn't find how to make the electrical connection. Did you use any capacitor? Why 3 wires in the terminal box?
I do like seeing things blown up but I like seeing the building and rebuilding stuff more like the Kelly and Lewis and the Westinghouse generator. Maybe the Kelly and Lewis could be paired up to power the Westinghouse but it probably doesn't have enough grunt to turn it over at full RPM, but the Morris engine might, the Datsun and Jag engines would for sure.
Great video. I'm looking for a compressor that produces the most pressure. From what I understand, a "Scroll" compressor can produce the highest pressure. What may I expect for maximum pressure from a Scroll compressor? Thank you.
hi, i would ask you, what may happen if i use a frequency inverter to vary the speed of a air conditioner compressor, if i do that, will it work like a inverter air contitioner?, is there any problem if the speed of refrigerator gas vary? can i modify a old air conditioner into inverter technology?
Think its a 5HP comp. Ran a secondhand one up yesterday that i have just installed, its making a nasty sounding noise from the sump area, time will tell!
You made this video so I didn't have to take a hacksaw to one I have scrap and take 2 hours cutting it open proberbly slipping and slicing my hand open resting in claret going everywhere, I thank you, maybe overvolt it for a bit of distraction see how long it lasts running on 400v
Thanks for super videos. Have two questions. As I get to know, some Copeland scrolls have oil pumps on the bottom. Does it pump up the oil to some parts of compressor or the amount of oil within the refrigerant is enough? The place where you grind off the upper cap is where the top scroll body joints and seals?
Is your vfd similar to the inverter technology in the newer mini splits? Or does it just change the frequency of your A/C mains? I work with these everyday, but have never seen one run like this. Very cool video.
hi,sr.thanks you for your video about scroll compressor,and its parts and explaning why it stop and borned!so my english isn*t very good,bat i trie to understand yours!god bless you,i wished from venezuelan,now i have one scroll that it was not starting,and i put one master kit for scroll compressor,05 tons.and it allready gone on,but in side,making alot a wire sound.do you have any idea what happened inside?i*ll be waetingg for your answer.bye,see you i hope pretty soon by this way.
Gr8 vids Aussie! Keep up the gr8 work! Question: Would you happen to know the minimum watts this scroll requires in order to start up and maintain minimum pressure when installed in fully enclosed system? And how many watts you're using to start when open like this? Thnx again! Subscribed and liked!
perhaps a scroll compressor could be used like a roots type supercharger was for a siren. perhaps we could make a scroll siren. but we would need a way to force a bunch of air into it and mount a large megaphone like aparatus
what did he say at 31 seconds? stazer? I had recently taken apart a rotary compressor but do not know what to call that copper coil section? Any help would be appreciated
mountain177 hahah, no he is right... even if you didnt mean it, that sentence felt a little bit like hearing an old man say "there are too many foreigners here these days"
Kay Kunack Well there at too many coming from India where they can't figure out how to keep their dicks in their pants! Hell every damn motel and hotel are now owned by India people and I refuse to stay at any of them anymore! They can keep their bed bugs! We Americans invent most of the good stuff and then Wall Street executives figure out how to profit more from it being made in China through slave labor with the full backing of your congressmen since they are allowed to do insider trading and make a fortune while they send Martha Stewart to prison for it! Have I said enough?
mountain177 Believe it or not, there's a whole lot of more capital intensive manufacturing that goes on in the US. The problem is, it's usually for bigger ticket items like Full AC compressors (outdoor ones that would cool a house or an office building) like the one featured in this video. Anything from this to multi-ton units you'd find for really big units. The problem is more on the consumer side of things. A whole lot of crap that people just mindlessly buy on the regular from the store is so cheap that it's almost unfeasible to make here in the States. There's a reason why a typical no-name screw driver set at Wal-Mart costs 5 bucks.
I have a compressor like this which has a soft start on it, i have nothing but trouble with the soft start , anyone know do i really need it? would love to bypass the stupid thing!
lol I have no idea why they would put a soft start on a domestic AC unit, most have or need a hard start kit (start cap and relay) I would just delete the thing and see how it goes. you may notice more inrush current causing lights to flicker ever so slightly if its a large compressor tho.
there is a start cap inside the soft starter. older models of my heat pump dont have them but apparently the power company here in Ireland is looking for soft starts to be installed, must leave it easier on their transformers or something.

after 21 yesra the compressor has all the rights to give up :-)
Great Vid!

Congratulation Sir. It is a useful video for AC technician. I really appreciate your intention on making this wonderful video. Well done.
That's a very interesting compressor design. It looks quite efficient.

Hey Ed !!!
Fantastic Demo Brother !!!
AWESOME !!!
That was great! Thank you for the demonstration. I enjoyed learning about this.
Thanks for sharing..... was curious about the parts inside and how they work.... thank you.....
@troll22001 there are a few good animations showing a cross section in operation. this compressor needs to stay in 1 piece for now
All your Videos are Great Mate
Seriously though, I did wonder how a scroll compressor worked, now i know, thanks Ed.
Those things are quite a mechanical marvel inside, its seems a lot more complicated then just using pistons and cylinders, not compared to something like a radial aircraft engine of course. The scrolls themselves look like something you could use in a piece of ornamental iron work like a fence or a railing.
I have a 5 year old 2.5 ton that knocked after 3 minutes of start up for 10 seconds today.Had to shut breaker off to get pump to start twice yesterday.Today it’s cycling fine except wondering about the 10 second knock? Cool video.

Neat how those work! I wonder what the benefit is over a conventional piston type?
@HDXFH Date of manufacture is in the serial number. The first 2 digits are the year and the third digit is a letter that is the month.
Good Demonstration Ed!!, That has some sort of date code on the top of the terminal block shroud, i wonder if that's the date of manufacture
Very cool, never seen one like that open

I did this on my house with a 3 ton copeland scroll 3 phase compressor. works like a charm. saves a shitload of electricity $$$
That's how Inverter ductless splits work
Think its a 5HP comp. Ran a secondhand one up yesterday that i have just installed, its making a nasty sounding noise from the sump area, time will tell!
I wonder could it be used as a air compressor? Maybe more efficient and longer life due to less moving parts?
You made this video so I didn't have to take a hacksaw to one I have scrap and take 2 hours cutting it open proberbly slipping and slicing my hand open resting in claret going everywhere, I thank you, maybe overvolt it for a bit of distraction see how long it lasts running on 400v
Good video for scroll compressor work and inside pump open
would oil spray out of the high side as it runs ? I was thinking of connecting it to an air tank
Thanks for super videos. Have two questions. As I get to know, some Copeland scrolls have oil pumps on the bottom. Does it pump up the oil to some parts of compressor or the amount of oil within the refrigerant is enough? The place where you grind off the upper cap is where the top scroll body joints and seals?

Which is better a scroll or twin rotary compressor?
does copeland have patent monopoly on scroll case design or does other manufactures produce scroll case design also?
If it is not too late could you cut away parts to show how the moving scroll fits into the fixed scroll?
tnx for the video i learn a lot about scroll.
Please can i put oil inside? When am fixing new one.

which part of the mechanical of copeland scroll if the trouble is like knocking sound i heard?
very educational video there!
what do you think causes "scrambling"?
Does the motor run in refrigerant fluid?
I'm here for the compressors but stay for the blowing stuff up.
Nice job....mate

can you show me the terminal diagram of the compressor to VFD
That compresser sounds like a engine!
what did he say at 31 seconds? stazer? I had recently taken apart a rotary compressor but do not know what to call that copper coil section? Any help would be appreciated
It's called the stater
"stator"
nice sounds kind of like a victa 2 stroke mower
very educational video demo
Proud of you Aussie brother!! It would top it off if you were a QLDer??
very informative. Thank you very much!
thank you very good video
Very interesting!
Greetings friend.
I would like to know how we open the compressor housing?
you have to cut the top off with a grinder.
Aussie50 congratz xD, was it hard because i think That that is not a easy job
Thanks 4 the information shared
@reddragon27284 oh yes!, there will be flames for this compressor :D
Excelent vid. Many thanks.
Great video!
Thanks!
Good video...
sounds like a dirt bike motor @6:30~
thanx sir
Where abouts are you based mate?
do a video about a hitachi scroll compressor
anything "made in the U.S.A." is hard to come by these days.
fuck u
carl daboss well, arent you just a little sack of sunshine! i was only sauing here in the usa, you cannot hardly buy anything that is from the usa.

Well silly, bolt it to the table then! :) Just kidding - have fun, but have safe fun. It's all sh*ts and giggles until someone touches the MOT!

blwing stuff up
Thank you
thank you aussie50
@V8Jagnut In the words of Photonicinduction, "I want flames!!!!". Lol
I'd rather have this kind of video than mindless destruction. But if one works for the other, who cares.
THANKS
sounds like a dirtbike lol
Sounds like a lawnmower engine.
COPELAND SCROLL ZR61 TFD KAC 522/250 (5 PK/HP)
if you could figure out how to convert one of these to run on DC, you would really have yourself something
simple bcoz its three phase so their is no need of capacitor for it
cool but needs to end with fire :D
bolt it down and floor it until it fails
Sounds like a really weak engine.
somebody stole your video
Thanks
Thanks
