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!

[@Copeland_Company]

Thank you for the great feedback @donathon Joffery Trump! 👍

[@eclipsekcb9201]

They are built by slave labor in Lebanon, Missouri. You're able to save money because they pay their workers zilch.

[@karendouglass8117]

I worked at Copeland in Lebanon also. When they first opened. Loved my job in scroll dept. Then became an auditor. Loved both jobs. The pay was better than most companies in the area. It was a great experience and opportunity. Thank you

[@karendouglass8117]

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.

[@FerralVideo]

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

[@cesar235cs]

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

[@Copeland_Company]

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.

[@meclucas]

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

[@br5747]

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.

[@channelasianewterminatexii7594]

u have to put flexible pipe through the compressor cuz if u dont they sound very loud that was my experience.

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

[@thienhavinh7431]

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

[@uncontrollabledogs3791]

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

[@poormanskint3008]

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.

[@ref-technogenetiki6817]

for multi sircuit applications it is better to use more than one compressors to carry the load for example one Digital scroll and three fixed scroll compressors or one full inverter compressor and three constant speed compressors with Carel Prack 100/300 or Emerson CPC.

[@garymorgan4192]

Changed a good few of these on the same site as the body has either snapped the discharge line upon start up or burnt out due to lack of oil return. Body was empty. Rather have a co2 packaged unit

[@FruiceProduces]

What is the danger of having 2 scroll compressors in the same circuit?

[@gregorymalchuk272]

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?

[@jehandwi4774]

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

[@dand1486]

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

[@patriotvoice8952]

Awesome presentation and clear information .. thank you

[@jeffreystroman2811]

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

[@JROrg2009]

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

[@jhh764]

Not what they meant by that. It won't rotate backwards

[@br5747]

If it runs in Reverse for more than about a minute it'll be trash and need to be replaced.

[@Brisket9392]

Scroll compressors only function in one direction. Heat pumps just have a reversing valve which basically makes the condenser the evaporator and evaporator the condenser. 3 phase scrolls (commercial/industrial applications) must be checked for correct phase or the scroll won't pump and will eventually quit.

[@JROrg2009]

@@Brisket9392 Yes, that's what I meant by "run in reverse", via the changeover or reversing valve.

[@I_Lucid_Dreamer]

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?

[@LongTrout]

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?

[@BRISTOLFORCE2009]

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

[@brdhus]

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.

[@fudogchomp]

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

[@fabiobouhabib7160]

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"?

[@AgentOffice]

They sand against each other slightly

do copeland produce screw compressor?

[@SuperManhattans]

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 ?

[@caru3257]

Tinnapop. not an expert but maybe to avoid liquid getting to the compressor.

[@Copeland_Company]

Hello Tinnapop! The image is a pictorial representation of a ‘shock loop’ recommendation to minimize line vibration. The system designer would determine the requirement based on tube design and testing.

[@newtecnoclimasrlsgv4939]

the scroll technology is the best.

[@Copeland_Company]

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.

[@Giobl1nd]

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-....

[@Copeland_Company]

Hi Giorgio! Thanks for the question. Since you have a digital scroll compressor, the problem might be that you might have a bad unloader solenoid valve. The solenoid is cycling on/off but the valve is stuck close that's why the compressor doesn't unload. We suggest that you try and replace the valve and see what happens. Hope this helps! If you have any more questions, you may contact our Copeland Technical Support at 973-498-3926 (Option 1 for Contractors | Option 2 for OEM). Have a great day!

[@Giobl1nd]

thanks guys, I 'will try that option because I did all the measurement I could do.. my last option is replace the valve ( I have the external type ) .. may could be also some internal problems, I mean Mechanical problems like some spring or maybe a sized component? cheers from Italy @@Copeland_Company

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

[@DWAYNE2ism]

Copeland compressors on service is very efficient

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

are u crazy!? semi hermetic pistons where the best but they got rid of them because we where able to rebuild and fix many of the problems with thwm and that dosnt help copeland sell more compressors. Everything has become shit in hvacr, everything just gets thrown in the trash and replaced. The scroll is shit, give me a semi hermetic with unloaders and call it a day.

[@RrRr-th1kf]

Spiral compressor is bad because of dynamic of compressing gas inside it .. rotary and piston is best and better than spiral compressor

[@eyadalhazouri9537]

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?

[@Copeland_Company]

Scroll compressors will run at higher compression ratios, often exceeding 14 to 1 in low temp refrigeration applications. One must refer to a specific compressor's operating envelope to determine what refrigerants and applications the compressor was designed to work with. Generally speaking, Copeland recommends that discharge line temperatures exceed 225 degrees six inches away from the discharge port.

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.
