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 , !
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.
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
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
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!
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.
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
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
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.
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...
"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.
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
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?
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?
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.
Lost me on the increases temperature and not heat statement when you immediately went to it "losing that heat". Think you meant increases in temperature means it increases in heat density, meaning amount of heat contained within something . But spot on none the less.. just a way of wording things that had me questioning my definitions of things.. :)
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

Nice bro iam from Ethiopia Refrigerator maintenance .uf u have information, vacancy i need thanks
InstaBlaster.
You teach very well.
The way of your teaching reminds me when I was in technical schools in Germany .
You are true professionl.

I have been in Germany.
The style of your teaching reminds German colleges .
Great job ,
You are true professional. Please continue 👍

I'm taking HVAC classes so stuff like this helps alot. Big pp points to u
Nice work on all your videos. You folks do a great service to our excellent industry. Thank you.
Extremely knowledgeable video with expertly explained concepts.. thumbs up for the great work!

Soooooooo glad I found this channel !!
Hey that's Matt Risinger in the intro! Love the build show
Simplified and easy to follow. Good video!
Great video! I'm in school right now and every little bit of knowledge helps!
I like the way u put things out ! simple , clear and plain. Thx u sir .
I have swapped my live and neutral line. Did I damaged my compressor. Thanks for your help
I love how you explain step by step 👏🏾, very knowledgeable , big help thanks

This tutorial the best so far thank you for sharing I learn more about compressors.
Glad it was helpful!

Glad it helped
I wish i had these videos when I studied. Great work!
Thank you very much. Very helpful and educational video
Great job
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.
Great stuff i am a new apprentice this videos have been great
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
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 clear explanation, wish you luck in the future.
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
Thank you for the video.

Thanks for the great video, Have you done one on charging a system on Amps or Compressor LRA (Lock Rotor Amps)?
Thank you
Elaborate
Very professional, thank you Sir.
Very nice explanation and. Helpful
Well done!
Love your content. Thank you for knowledge

Would love to see a illustration of where the vapor is converting to liquid.
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?
Very easily and nicely explained . 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...
Very well put. Thank you sir
SUPER EXPLANATION.
Great video man!!!! 👍👍

Nicely explained full marks to you Sir.
You’re soooo gooood! Thank you!

I set up a milk chiller for an off grid farm using a diesel lister engine :)
Excellent video
Very well Explained. Thanks!
Glad it was helpful!
Beutiful image, "when you compress the gas the molecues start bumping into eachother more frequently and heat up," aka friction.
Great information
Nice job and video
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?
Nice explanation
Thank verry good introduction lesson
Excellent.😀
Very well explained, thanks so much
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?
Nice information thanks bro keep it up
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?
Thank you sir. Hope you will continue making a educational videos about HVAC world.
Ok..so this is Compressors 001.
Any HVAC person should know this from the start.
Hello Bryan
Can you replace R22 compressor that is absolute with R410 compressor after removing POE oil and replacing it with mineral oil?
Masterful just masterfully said,thank you!
Very insightful! Very clear explanation of principle of VC Cycle without using any diagram!
Thanks, excellent show
This is great video . How to determine a metering device without opening the plenum?
Thank you!
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.
Thank you 😊
Thank you.
Thanks again 😅
Compressor split I always looked at.
How much oil does it take. What should the oil level be?
Lost me on the increases temperature and not heat statement when you immediately went to it "losing that heat". Think you meant increases in temperature means it increases in heat density, meaning amount of heat contained within something . But spot on none the less.. just a way of wording things that had me questioning my definitions of things.. :)
Wow amazing information
Many thanks, this video was amazing & very helpful.
Nice video, 🇮🇳
Great videos ! Thanks.
What do you mean by compressor sheel by inject bulk of oil?
@4:34
Do you instead mean "then the compressor is going to do *more* work and run hotter"?
Love your videos
thank you very good
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?
Nice video.
What do you mean by oil lost? Does it mean literally lost/gone?
Damn good tutorial!!
thanks
Great video. Would refrigerant migrating happen in a hermetic compressor in a cold ambient?
If the temp is bellow 32 on a 404a compressor on a freezer am I getting liquid feedback?
You are my hero
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
Whst specifications to be checked when same manufacture not available for scroll compressor to be selected, could u let me know
wow, please keep uploading new videos thanks
Wait? How is heat different from temperature?
