This is the best video for many reasons: 1. You actually know your stuff 2. You are confident. 3. You are a good teacher. 4. You are actually teaching and not reading from pre-recorded stuff. 5. Excellent pace and not robotic.
Very nice. I've been in Maintenance for 20 years and have worked on many AC units and you taught me some things. This will make me a better maintenance man. You don't realize how much you really don't know or forgot until you watch someone with extensive knowledge of AC systems. Thank you.
I know this video is old and nobody will read this, but Ive been studying HVAC for about 2 weeks. You just explained in this video wouldnt I couldn't pick up in 2weeks. Honestly you just broke it down and made it easy to understand.
Definitely the clearest explanation I could find! Just started my apprenticeship with the Union and I figure this is a basic thing I need to know. Great job on the video and thanks for explaining it so clearly!
Watched a few videos all on the refrigeration cycle and yours was all around the best. You started with the comparison of super heat, saturation, and sub cool. Went step by step on how each state was reached. That was very helpful. You didn’t go to fast. Great job!
I really appreciate this I’m currently going to school or become a hvac technician and right now we are on the refrigeration module and let me tell you I’m lost like a mother I was beating my self up bc it wasn’t clicking in my head my girlfriend told me to study today so I was like okay first vidoe that popped us is yours and now I’m finally understanding the cycle of refrigerator from the inside unit and outside unit and how it alls works. Thank you
I'm not studying to go into refrigeration but I need to understand it because I am studying to go into facilities management. The refrigeration sections were the hardest. I understand it so much better just after this one video. Awesome explanation. Thanks
Excellent video with just the right pacing. Best i have seen on the subject. Also kudos for providing a text reference. I will be studying that for sure.
I really appreciate your advice I'm in school now and I was trying to wrap around my head how to understand a refrigeration cycle but I definitely understand it now I appreciate it
I just want to echo Joe Wright comments right below. I agree with the comment for all the reasons he mentioned. Excellent video. I watch a number of other ones on the subject but this one is by far the best. Good Job.
Could you share how long the cycle time from the compressor to condenser, to the coil inside the fridge or freezer until to flow back to compressor per time? say if roughly took about 30 mins for cycle times from compressor flows vice versa, it will took about 48 times per days for compressor to refrigerant vapor and receive the evaporates gas. correct me if i'm wrong.
75% liquid & 25% vapor that enters evaporator is sub cooled? In the middle of the evaporator it is 100% vapor at saturation temperature? Toward the end of the the evaporator the vapor is super heated?
Hello in the cycle the line size no one ever really address that for me I see it in the capillaries. I'm sorry I can't explain myself 😅. I just did my first r290 and I'm just looking for info. Thank you very much
This may sound silly but, if the suction line is under a positive pressure before it reaches the compressor why is it referred to as a, "suction line", my interpretation is that suction implies negative pressure (a vacuum). Is the compressor not just forcing the refrigerant full circle, or is there a negative pressure pulling the refrigerant at the compressor that the gauges don't detect? (maybe my definition of suction is incorrect) Could you please explain?
I had to laugh at about 2.5 minutes in. LOL. I was caught off guard by the past-a pronunciation. I’ve always said paw-sta. The more you know LOL. Great video by the way from an apprentice.
Any questions ask away, we may be able to answer these in other video.
I have a few questions

5. Excellent pace and not robotic.
Thank you, I wish I had my Bluetooth mic here like my other white board vids but ah well lol.
@@HVACKnowItAll Yout presentation is truly remarkable. I will refer to it continuously and will recommend it to colleagues

Glad to help !
Probably the most clear explanation of the refrigeration cycle I have found on here. Thank you.
Cheers man, glad to help!
I would agree. Very comprehensive.
I know this video is old and nobody will read this, but Ive been studying HVAC for about 2 weeks. You just explained in this video wouldnt I couldn't pick up in 2weeks. Honestly you just broke it down and made it easy to understand.
I read it! Thanks Jessica !
@@HVACKnowItAll No problem. Do you have any videos on Chillers or any other system. How can I get your lastest or more recent videos.
A very clear, easy to grasp demonstration of the refrigeration cycle. Thank you!
Thank you
Definitely the clearest explanation I could find! Just started my apprenticeship with the Union and I figure this is a basic thing I need to know. Great job on the video and thanks for explaining it so clearly!
Thank you!
Best video for New Technicians.
Thank you!

Currently in Level 3 Technical Training for Refrigeration and this was the best explanation I've heard yet
Glad to help!
This was the best explained video I’ve seen THANKS
Thank you and you're welcome

My pleasure
One of the clearest explanations I've seen. Thanks!
Awesome video! Took your time to explain everything. Not talking fast like other people do posting videos, thanks!!
Thanks man ! Taking classes right now and my instructor is great hands on but has a hard time explaining textbook
Excellent video with just the right pacing. Best i have seen on the subject. Also kudos for providing a text reference. I will be studying that for sure.
Thanks man, much appreciated
I knew how to measure and calculate subcooling and superheat, but I had never understood it %100 until today. Thank you
I love the breakdowns, this is the only video that makes me understanding how the cycle worked. Thanks a lot
I really appreciate your advice I'm in school now and I was trying to wrap around my head how to understand a refrigeration cycle but I definitely understand it now I appreciate it
Cheers, glad to help
Great explanation sir...from the Philippines..have a great day...
Thank you!

Thank you for all of the detail. Going for my 5th class power engineering soon. I love understanding why things do what they do
Great video, you explained things very well. Helped me pass my ACR 21 Final.
That definitely makes me happy! Congrats
This vid is top 1 percent. Superlative teacher.
Much appreciated
How easily u explain everything thanku...🙏
I try lol
Very well explained. Thanks bro
You're welcome
I watch this stuff as a hobby enjoy learning thanks
the best explanation ever
Than you!
Bro!!! Thank you so much for this video. I have so much clarity now
I'm sure this makes perfect sense to other people who already know how refrigeration works
This is grass roots teaching, the way I was first taught before knowing anything!
I've never had Paasta however I'd like to try it some day. I'm tired of plain ol' pasta...!! LOL Great Video...!! Thanks and Happy Holidays 21'
Started learning today
Awesome
A very good explanation.
Thank you!
👏👏👏 Great presentation!
I appreciate that
Thanks.. you explain very well
You're welcome
Thanks in a million. Great content. Awesome. Grade: A++💥
Appreciate it!
Very good teacher
I appreciate that!
Great content! Straight forward and clear. You know your last name, roughly from Gaelic, stands for expert?
Thank you! Interesting, I did not know that at all.
New subscriber here. Great explanation!
Thanks Ian! I will try to keep it up haha
crystal clear explanation
Thank you!

Thank you!
Explanation is well said and I think you are on to your new calling 😉
Bert good explanation 👍👍🙌🙌
75% liquid & 25% vapor that enters evaporator is sub cooled?
In the middle of the evaporator it is 100% vapor at saturation temperature?
Toward the end of the the evaporator the vapor is super heated?
Hello in the cycle the line size no one ever really address that for me I see it in the capillaries. I'm sorry I can't explain myself 😅. I just did my first r290 and I'm just looking for info. Thank you very much
How did you get the saturation/boiling point?
Of the refrigerant?
Thank you!
Thanks!
My pleasure

Is the compressor not just forcing the refrigerant full circle, or is there a negative pressure pulling the refrigerant at the compressor that the gauges don't detect? (maybe my definition of suction is incorrect) Could you please explain?
No negative pressure in most systems. The compressor creates a pressure difference between two sides. It's a funny term I know.
Superheated vapor enters condenser?
Then vapor converts into liquid at saturation temperature?
Then temperature further drops to sub cool temperature?
Good video
Thank you sir
dude ... your killing me w the word PASTA lol my italian ancestors rolled in there graves.
My father inlaw is from North Italy, says it the same way.
Great job Gary, but you are saying pasta wrong 🤣🤣
Everyone knows it's not pawsta...me wife is an Italian lol
Thank you Sr
I had to laugh at about 2.5 minutes in. LOL. I was caught off guard by the past-a pronunciation. I’ve always said paw-sta. The more you know LOL. Great video by the way from an apprentice.
Haha, thats funny
theres a reason this video has no dislikes
Not yet....lol
Thanks!!
So what happens in the air conditioning cycle?.. Can you explain the difference?
There is no difference, air conditioning uses the principles of refrigeration
@@HVACKnowItAll Thankyou Its only that evaporator coil comes with fan in case of air conditioning right?
Should really draw the 4 main components in the some position as they would be in an enthalpy graph. Saving confusion later.
thanks

Pressure cooker superheats vapor because in pressure cooker water boils at temperature higher than boiling point
Your "Refrigeration Cycle Explained" video, is not playing?
It's playing on my end
#hvac #refrigeration
👍👍👍
Pasta… bro. Where you from.
Lol, it's not spelled Pawsta. I'm from Canada
Thank You😎
