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
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
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
"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.
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 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
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?
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...
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.. :)
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?
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?

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 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 , !
Trying to get my universal refrigerant license and this helped a ton. Thank you!
Nice work on all your videos. You folks do a great service to our excellent industry. Thank you.
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.
I'm taking HVAC classes so stuff like this helps alot. Big pp points to u

Extremely knowledgeable video with expertly explained concepts.. thumbs up for the great work!
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 .
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.
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!
Hey that's Matt Risinger in the intro! Love the build show
Soooooooo glad I found this channel !!
I wish i had these videos when I studied. Great work!
Great stuff i am a new apprentice this videos have been great
Thank you very much. Very helpful and educational video
Great job
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
Really well-explained video of the process. Not in the industry but I found it quite fascinating. Thank you.
That’s was the best explanation So far
thanks!
Very nice video. Very explanatory. Thank you sir
Thank you for the video.
Very professional, thank you Sir.
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
Love your content. Thank you for knowledge
Very nice explanation and. Helpful
Well done!
Very well put. Thank you sir
Very clear explanation, wish you luck in the future.
Great video man!!!! 👍👍
I have swapped my live and neutral line. Did I damaged my compressor. Thanks for your help
SUPER EXPLANATION.
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
Excellent video
You’re soooo gooood! Thank you!
Great information
Nice job and video
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!
Very easily and nicely explained . Thank you
Nice explanation
Would love to see a illustration of where the vapor is converting to liquid.
Excellent.😀
Thank you 😊
Thank verry good introduction lesson
Nice information thanks bro keep it up

I set up a milk chiller for an off grid farm using a diesel lister engine :)

Very well Explained. Thanks!
Glad it was helpful!
Thank you.
Masterful just masterfully said,thank you!
Nicely explained full marks to you Sir.
Very insightful! Very clear explanation of principle of VC Cycle without using any diagram!

Thanks again 😅
thank you very good
Thanks, excellent show
Thank you sir. Hope you will continue making a educational videos about HVAC world.
Thanks for the great video, Have you done one on charging a system on Amps or Compressor LRA (Lock Rotor Amps)?
Thank you
Elaborate
Nice video, 🇮🇳
Great videos ! Thanks.
Wow amazing information
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
Love your videos
Nice video.
Compressor split I always looked at.
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?
Awsome explanation !!!!!!
Beutiful image, "when you compress the gas the molecues start bumping into eachother more frequently and heat up," aka friction.
You are my hero
Damn good tutorial!!
thanks
Many thanks, this video was amazing & very helpful.
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?
Great video like always.😀
Ok..so this is Compressors 001.
Any HVAC person should know this from the start.
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...
Hello Bryan
Can you replace R22 compressor that is absolute with R410 compressor after removing POE oil and replacing it with mineral oil?
Thanks
Welcome
1 more subscriber. You're doing a good job
@4:34
Do you instead mean "then the compressor is going to do *more* work and run hotter"?
This is great video . How to determine a metering device without opening the plenum?
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?
wow, please keep uploading new videos thanks

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?
If the temp is bellow 32 on a 404a compressor on a freezer am I getting liquid feedback?
Wait? How is heat different from temperature?
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.
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?
Are there any video around that show how to install, troubleshoot and service semi-hermetic compressor.
What do you mean by compressor sheel by inject bulk of oil?
