Copeland Scroll™ Compressors for Refrigeration Applications 

I'm a service manager for 4 multi-family apartment communities and I have installed many Copeland Scroll compressors. When properly installed these compressors give excellent trouble free operation for many years. They are an exquisite piece of machinery expertly designed and have saved my company thousands of dollars!

I love Copeland corporation I worked at the Copeland they built in Lebanon Missouri worked in scroll department, then became an auditor. I absolutely loved my job. The pay was good. The benefits were good. My job gave me the confidence I needed. Thank you Copeland.

Okay that digital control unload system is REALLY cool. Looks a lot more reliable and affordable than a variable speed compressor.

Very clear and informative video. The only thing they failed to mention is that the loading and unloading sequence is so loud on a rooftop unit that it can be heard down through the building and everyone is screaming about the noise. I usually have to disconnect the unloader. I've had several customers say that they don't care if it's hot or cold in there as long as we can stop that horrible noise. This has happened on several buildings with rooftops with these style compressors.

Finally I understood how digital scroll compressors operate!!!! Tks

The compression ratio of a scroll compressor is based on the volume of gas it intakes in the suction pocket divided by the volume of gas that is discharged. Most scroll compressors are fixed compression ratio machines. Copeland Scroll compressors exist in many displacements and for many applications. Therefore, different compression ratios are designed into the various models that are manufactured in order to make the products as efficient as possible for the applications that they go into.

I really appreciated this video, the animations are clear and easy to understand. Thank you.

wow, so when the unloader/loader energizes, the pressure drops thus reducing the pressure or sucking the top scroll upward?🤔🤔🤔

Very helpful graphic, is this the same shape of a scroll type air compressor?

Awesome presentation and clear information .. thank you

Emerson needs to use this design in residential appliances.

Very cool vid. But needs pictures of the side discharge plates. How is the side plate wear controlled?

i just new student. thank u for everything

This compressor is freaking crazy.

Regarding the digital scroll application, I've seen another video more specific to its operation, a very good explanation of the off loading/capacity control function. Its a bit like the slide control on the screw compressors but offering fully off loading on a selectable time base. I might be fitting a second hand system that has several mid temp evaporators individually controlled, and I'm considering using EPR valves so that when the individual evaporators are satisfied, they don't pump down into a vacuum. The condensing unit has a digital scroll on it, so if the all the evaporators are all satisfied, the low side pressure switch will pump the low side pipework down after the EPR valves, and shut the compressor off. But if there is one or more evaporators that aren't at their set point, the compressor will off load to maybe 10%. I am trying to find out what controls the modulation of the sol valve, is it varying suction pressure from a low side transducer, or pipe wall temperature on the low side that signals a controller? Also regarding oil return, it states on the Emerson pdf for this compressor that it is undesirable to use an oil collector for some reason? But I am concerned that when the velocity reduces right down to when the compressors off loaded to 10%, it won't be sufficient to return the oil that has already carried over. So I am planning on using a double suction riser and adding a shot of oil to compensate for trapped oil carried over from when the compressor is at full load.

Is there any way (mechanically) the unloading assembly (for a lack of a better term) can be stuck open? Or would that have something to do with the digital scroll controller and it’s control of the unloader solenoid?

What is the compression ratio?

Is the 20% increased efficiency over reciprocating compressors or rotary vane compressors? Also, what is the cause for most of the efficiency improvement? Better Volumetric efficiency? Less mechanical friction? Less fluid friction?

Is the opening on the lid the high (discharge) line?

do u need a check valve on the discharge of the dig comp if it on a rack, sharing same suction/discharge header? (example:1 dig comp, 2 reg comps) prefer to know for the discuss 3D, but like to know for both. thx

I want one to work with a windmill ?

That's an interesting application. Our Design Services Network team could probably help with that. We've added a link to their web page to the video description.

Thank you very much.

I agree with Buddy tagart who said a comment earlier, I also wish a semi sealed scroll compressor without a seal and it with a magnetic cuppling or seperating of motor by stainless steel doom around the rotor, So we can produce small sized NH3 Units

hello, thanks for your Video, i will ask, can the compressor reach the pressure 14 bar from 1 bar? and what about the temperature at the discharge?

could you please tell me if this statment is true "The motor compressor is suspended by springs in the capsular housing which minimises the transmission of vibration to the capsule body, thereby reducing noise Emission"

i even thought of using magnets instead of a shaft to connect motor and scroll then there would eliminate a seal,

Ricardo, May we contact you to get some specifics regarding your comment? If yes, please message us with an email and phone number. Thanks!

is there no tip seal?

My compressor (just installed as a replacement for the old) gives rattling sound for about 30-40 sec and then functions smoothly... technicains says this si due to liquid refrigirant at the begining? is it true? Fan starts---> 30 sec rattling sound from compressor--> continues ralling for 40 sec--> quite operation...? any thoughts.?

Very well explained, thank you for this video! However, I was just wondering, how do the scrolls actually "wear in" instead of wear out? and what happens when they "wear in"?

Realy that is fantastic tecnalogy.......

I was looking at Copeland scroll compressor for Air conditioning (CPL_Covers_AGL) on page 9 the title is suction line noise and vibration. I'm curious from looking the suction pipe design picture. Why do they have to bend to be like U shape on suction line before entering the compressor ?

BTW, many scroll compressors, likely Copeland too, can run in reverse, for applications in say, heat pumps, electric automobile passenger heat / cool needs, etc.

I am suspecting that when you charge a copeland scroll with liquid through high side while under vacuum causes internal damage with the result being equalized pressure while running....If so why?

Thank you

Very good company all item & compressed good working.

Very good and funny videos bring a great sense of entertainment!

Help! I have digital scroll comp in a Liebert lan room unit. Compressor make a HORRIBLE chattering noise and does no work with or without unlaoder sol engaged.

the scroll technology is the best.

Professor Al-Aziziyah, the reasons for the weariness of the mechanical part

Is this for low temperature application...wahat the model no.

So how does this compare with the LG linear compressor? Could someone explain to me that Lg linear compressor really has design flaws that dies within 2-3 years? Based from bad experience/comments in the internet wc im not sure if Lg is just being targeted of marketing sabotage, im planning to buy an Lg fridge but based on what im reading im hesitant to get it. Pls help me decide😕😕

whats the problem if I hear the noise of the solenoid valve but I don't see the variation of HP and BP ? mine compressor seems to be always at 100%, but i hear the correct cycling and the noise of the solenoid valve-....

how did you do it can you share with me , thank you

IT WOULD BE INTERESTING TO SPANISH TRADUCTION

Scroll compressor में warranty क्यू नही आती

do copeland produce screw compressor?

let me use this video as a learning video, i;ll share the link in my description. Thankyou very much...

Could I ask you one thing? And that is, can you please bring back reciprocating compressors?

very good thank you

scroll compressor are the best

Great field to work in. where else can a tech earn $140 an hour.

CAN i REPLACE A COPELAND RECIPROCATING COMPRESSOR BY A SCROLL??? 2) THE ACUAL IS MODEL SRD6-0225-PFV B/531 109-1365 COPELAND

why can't Emerson build a two part compressor with the motor out side the refrigeration unit. even it you had to cool the motor say-pert it would eliminate system contamination and add to life of over all system. when i came up commercial compressors were belt driven.i am not saying go back to belt drive . direct drive would be ok.motor out side compressor Huck to it. by shaft.

very good company all items compressors

informated video

teams are very good but the service is bad as well as the support.

sigue pa lante esto funciona mete mano

Muito bom !!

Good Technology

Copeland compressors on service is very efficient

copeland compressor is the best

good brand

Sir please Hindi m explain Kare

Please stop using scrolls on freezers at -10

Trustworthy

Portuguese please...

Good luck

Hindi me bolo sir shamgh me nahi aya

pruan numbar

Junk compressor, bought my Rheem unit 4 years ago and it's already broken the compressor.

The gas inside scroll compressor Is not compressed well Because dynamic of compressor is spiral ... so the gas will not compressed well Scroll compressor is bad Rotarty compressor and piston compressor is the best

Говно компрессора ! Горят как спички.

Horrible tech support
