Excellent. Many people don't realize that compressors are cooled by the proper refrigerant charge, using that coolant on the return or suction line, to keep the compressor from overheating. Thus destroying the oil and parts within the hermetic or semi-hermetic compressor. Very well explained. Thank you for all of your superb videos.
the video is factually correct with good usage of technical terms that most technician would have a problem with. Plus, a good explanation of why the temperature of the vapor refrigerant is increased was made. Some people would mistake increasing pressure means increasing the temperature but in fact the superheated complete vapor does not correspond to pressure/temperature relationship.
i still have a troubleshooting card on compressors from way back in school there are so so so many possible reasons for failure of a compressor your have to be a genius to remember them all , !
Your channel is amazing brother, thank you so much 🙏🏻 I'm just getting into refrigeration at work and your channel is going to help...Hermetic compressors are the ones we work with in the stores. I'm just learning about them and it's really interesting
it is a great video! Thanks! I just believe that a higher compression ratio means that the compressor is compressing the refrigerant vapor to a higher pressure, resulting in increased work done by the compressor and higher system temperatures.
Wow! So glad I found your channel this is so awesome!! I work in residential construction, not in the HVAC trade but lately have wanted to understand more about it, mostly because I wanted to install some ductless heat pumps, but I'm falling down a rabbit hole and it's great! Thanks for the education it is definitely improving me! So again thanks for that!
I did not have much science in high school but years later I have had the oppertunity to gain insights of physics of fluids and their properties of change from one state to another . Brian you must have had alot of school science to grasp and understand the laws of physics . You do a great job of presentation in this video , and not lecture over our heads of your topic on compressors . I gather more and more information and evolving skill each time I watch your videos Cheers
This was helpful. I wasn’t sure if the gas went to a liquid after the compressor. Makes sense though as heat will need to transfer into the outside air and gases do a good job transferring heat.
Just wanted to thank you it’s my second week as a apprentice first year. There is so much to learn. The way you break down the subject is really helpful. Keep up the good shit bud
Hello Bryan Question, if you have r22 compressor and it is absolute can you replace it with R410 compressor remove compressor POE oil and replace it with mineral oil and charge it with R22 refrigerant will it work?
Please help me understand my Copeland compressor. It is a scroll compressor from 2000. There’s another cylindrical tower next to it it’s probably 1/4 the size of the compressor but similar in appearance. What is this other piece of hardware do and what is it called? You have a great videos thank you
6:41 I live in a desert (+120F in summer). Many people suggested to insulate the section line that goes back to the compressor in my car to have colder AC. What do you think about this, will it harm the compressor because I made the refrigerant much colder than I supposed to be?
I heard from someone that a guy had used a plasma cutter to cut an AC compressor open, when it was still under pressure. Something like, he ended up in the hospital as a result. How much PSI does a scroll compressor usually hold?
I thought it be cool to make an off grid refrigeration system based on an open Drive compressor. Then you could have a DC motor spin it and be able to swap it with a gas engine, propane engine. Whatever you want. Control system would be difficult but totally possible. Love the videos by the way learning a lot
what would be a bad compressor ratio? i had an r22 runing on my low side at 96 with a discharge pressure of 267. it was a new customer i dont know what the previous company did, lst company was their 5 years ago. i replaced the fan motor, cusotmer didnt want a new unit, so basically i made it clear to the customer that unit will not operate efficiently
I would love to hear your thoughts on l.a.c.'s I am producing a custom 40 ton wall mounted unit and we are having trouble with out l.a.c. especially on startup.
It’s actually an increase in density. The denser you pack a liquid, the more energy you’re gonna get (heat that is built up). The compressor packs the refrigerant into a condenser, but it also pulls on the suction line, creating a vacuum. It creates both hot and cold at the same time.
PLEASE HELP ME I bought a 1.5Ton 5Star inverter Ac 2days ago a installation team came for installation, they installed the indoor unit and the outdoor unit perfectly and Vaccum the system through the charging hose (service line) after Vaccum the closed the valve of Vaccum motor and turned the Vaccum motor off after this he turned the discharge line (liquid stop valve) for 5sec and turned it off to check leaks till this everything he did was perfectly right as the manual said but after this the manual said to Disconnect charging hose from gas stop valve's service port, then fully open liquid and gas stop valves. But instead he opened the discharge line completely and then started to disconnect charging hose from which the gauge was connected as soon as he started open the gas started to leak from the charging hose and he took almost 30sec to disconnect till than it was leaking and it stopped when it was disconnected and at last he fully opened the discharge line and now Im overthinking and living in fear that what was that gas was it the refrigerant or the compressor oil or it may have suck air inside the compressor or coils because it was vaccumed, it may have contaminated the refrigerant that May lead to BLAST (Explosion) OF COMPRESSOR NOW IM Living in fear that it may blast any time what should i do now Please help me
At 4:33 the video said the compressor is going to have to do less work, and will run hotter. It should say 'more work', right, to increase from a lower pressure to a higher pressure?
It is true that compression ratio often goes up when suction pressure goes down and this results in less overall watt input to btu efficiency. Nevertheless, when the suction vapor is less dense (lower pressure) the compressor is moving less material and therefore doing less “work”. A single stage (typical) compressor has a fixed vapor volume and essentially fixed RPM (though it will slip more under greater load)
"Those are rare because you have a shaft coming out of the compressor" ..most cars on the road. Don't forget about MVAC. There might be more open drive compressors than hermetics, could the number of buildings and their AC and refirgeration units compared to vehicles.

Great video! I'm in school right now and every little bit of knowledge helps!
Hey that's Matt Risinger in the intro! Love the build show
Simplified and easy to follow. Good video!
I like the way u put things out ! simple , clear and plain. Thx u sir .
Soooooooo glad I found this channel !!
Thank you very much. Very helpful and educational video
Great job
I love how you explain step by step 👏🏾, very knowledgeable , big help thanks
I wish i had these videos when I studied. Great work!
This was helpful. I wasn’t sure if the gas went to a liquid after the compressor. Makes sense though as heat will need to transfer into the outside air and gases do a good job transferring heat.
Glad it helped
Great stuff i am a new apprentice this videos have been great
This tutorial the best so far thank you for sharing I learn more about compressors.
Glad it was helpful!
I have swapped my live and neutral line. Did I damaged my compressor. Thanks for your help
Just wanted to thank you it’s my second week as a apprentice first year. There is so much to learn. The way you break down the subject is really helpful. Keep up the good shit bud
That’s was the best explanation So far
thanks!
Very nice video. Very explanatory. Thank you sir
Really well-explained video of the process. Not in the industry but I found it quite fascinating. Thank you.
Very professional, thank you Sir.
If the temp is bellow 32 on a 404a compressor on a freezer am I getting liquid feedback?
Whst specifications to be checked when same manufacture not available for scroll compressor to be selected, could u let me know
Very clear explanation, wish you luck in the future.
Remember: a compressor cannot compress liquid
liquid cant be compressed
Even with a compressor.
Can only fit one. Gallon of water in a one gallon container. But you can fit a lot of pressurized air in that container
But it can come press deez nuts
Right so don’t charge the suction side with liquid haha.
Hello Bryan
Can you replace R22 compressor that is absolute with R410 compressor after removing POE oil and replacing it with mineral oil?
Very nice explanation and. Helpful
Love your content. Thank you for knowledge
Thank you for the video.
So what kind of pressure are we talking about? Say I want to build a fridge compressor. What pressure and flow rate should I aim for?
Can I run my home ac compressor nonstop for 8 to 10 hours each day without recycling with no damage to the compressor or to the evaporator unit?
Hello Bryan
Question, if you have r22 compressor and it is absolute can you replace it with R410 compressor remove compressor POE oil and replace it with mineral oil and charge it with R22 refrigerant will it work?
@4:34
Do you instead mean "then the compressor is going to do *more* work and run hotter"?
In Vehicle air conditioning they use a variable displacement compressor, axial piston design. The piston is driven by a wobble plate or swash plate.
I’ve taken one apart before. MVAC compressors are bizarre little things
What do you say, if AC compressor is tested by filled with 300-400 psi then from suction pipe come out black smoke? What can we do to repair it?
Please help me understand my Copeland compressor. It is a scroll compressor from 2000. There’s another cylindrical tower next to it it’s probably 1/4 the size of the compressor but similar in appearance. What is this other piece of hardware do and what is it called? You have a great videos thank you
Very easily and nicely explained . Thank you
What do you mean by compressor sheel by inject bulk of oil?
Great video man!!!! 👍👍
6:41 I live in a desert (+120F in summer). Many people suggested to insulate the section line that goes back to the compressor in my car to have colder AC.
What do you think about this, will it harm the compressor because I made the refrigerant much colder than I supposed to be?
They're correct. Unless otherwise specified most cars and their acs are still designed for cold climes.
Very well put. Thank you sir
I heard from someone that a guy had used a plasma cutter to cut an AC compressor open, when it was still under pressure. Something like, he ended up in the hospital as a result. How much PSI does a scroll compressor usually hold?
Very insightful! Very clear explanation of principle of VC Cycle without using any diagram!
Where do i find the tonage on a home ac comptressor
I thought it be cool to make an off grid refrigeration system based on an open Drive compressor. Then you could have a DC motor spin it and be able to swap it with a gas engine, propane engine. Whatever you want. Control system would be difficult but totally possible. Love the videos by the way learning a lot
I set up a milk chiller for an off grid farm using a diesel lister engine :)
Excellent video
Hi i am looking for a compressor for a 2 door side byside kennmore refridegarator.
what would be a bad compressor ratio? i had an r22 runing on my low side at 96 with a discharge pressure of 267. it was a new customer i dont know what the previous company did, lst company was their 5 years ago. i replaced the fan motor, cusotmer didnt want a new unit, so basically i made it clear to the customer that unit will not operate efficiently
Thanks for the great video, Have you done one on charging a system on Amps or Compressor LRA (Lock Rotor Amps)?
Thank you
Elaborate
How much oil does it take. What should the oil level be?
Would love to see a illustration of where the vapor is converting to liquid.
Masterful just masterfully said,thank you!
Nicely explained full marks to you Sir.
What do you mean by oil lost? Does it mean literally lost/gone?
why the compressor fail frequently on dry cleaning machine pleas suggest the beast solation
I would love to hear your thoughts on l.a.c.'s I am producing a custom 40 ton wall mounted unit and we are having trouble with out l.a.c. especially on startup.
Wait? How is heat different from temperature?
Very well Explained. Thanks!
Glad it was helpful!
Very well explained, thanks so much
Thank you sir. Hope you will continue making a educational videos about HVAC world.
May i ask? Can the R410a Compressor using R22 refrigerant? And what the side effect of that?
Well done!
You’re soooo gooood! Thank you!
Great information
Another job of the compressor is to compress the gas to temperature/pressure above its saturation point so as to aid in condensing back to a liquid
Thanks, excellent show
Nice job and video

@@HVACS Thanks, need to mull that over. And the compressor runs hotter because there is less gas to cool it?
Thank verry good introduction lesson
"Those are rare because you have a shaft coming out of the compressor" ..most cars on the road. Don't forget about MVAC. There might be more open drive compressors than hermetics, could the number of buildings and their AC and refirgeration units compared to vehicles.
How do you make sure mass flow is correct for proper cooling of compressor. ?
Great videos ! Thanks.
how much PSI does the compressor produce
Excellent.😀
SUPER EXPLANATION.
If conoresed air get hot why the tank is cold ?
Thank you!
Excellent Information...
Which is best book in the market (In English Language) which guides about all types of Compressors from Individual use to Industry level...
Sir
I have one doubt
Why compressor increase the pressure
Are there any video around that show how to install, troubleshoot and service semi-hermetic compressor.
Is it possible to change the frequency compressor (RSporand) with another cylindrical (rotary) compressor in the same capacity or vice versa without changing the capillary in the same mechanical circuit? Sorry for the translation
This is great video . How to determine a metering device without opening the plenum?
Thank you.
Beutiful image, "when you compress the gas the molecues start bumping into eachother more frequently and heat up," aka friction.
Dear sir very good video!!!
In my country Greece all speak about compressors with Hp and this make a lot of misunderstanding!!!Is that way in your country ???What is your opinion about that?
Awsome explanation !!!!!!
