I'm a student in an advanced program where we have to create essays every three weeks on a STEM topic of our choosing. For this one, I decided to do Peltier elements, and when that proved to be difficult with how simple they were, I turned to refrigeration as an entire subject. I was having a hard time finding any in depth videos on their construction, but this video explains this stuff perfectly and concisely. Thank you so much!
As an apprenticeship instructor, I have struggled with ways to make this topic understandable; for my students as well as myself. You have done a great job with your explanations and diagrams of doing just that; making it understandable. Thanks and keep up the good work.
I was having a hell of a time understanding the refrigeration cycle for school and, unlike the gen ed courses I know so well from university, this is not something I could read once, take the exam, and dump it off later; I actually need to know this for the exam AND I need to retain it to be able to obtain and keep a job in my field. I’ve been trying on and off for weeks to find something that would explain it in a way that would make sense to me [online courses are new to me, so I only have reading as a way of learning, and it’s hard to retain that when I need reading and visual learning combined], but this helped. I stopped every so often to take notes, and in doing that, I feel confident that a little review here and there over the next few days will allow this to stick in my memory and I’ll never forget it. Thank you so much. I’ve liked and subscribed, and I look forward to any other videos you may have that will help me through this program.
Thanks . All your videos are easy to follow. Hopefully any new ones contain louder audio. I can only fully follow with headphones, which isn't a game changer, but would be nice to refer to these lessons anytime any place. Thanks again.
Good video overall, I know it's old, was looking for videos to explain refrigerant cycle to show my trainee. I am not sure I could recommend this video, however. Just some things that could help others who see this: -being overly specific on the cold/normal/hot etc of line temperatures isnt really necessary. For all intents and purposes we call anything after the compressor and moving downstream to the metering (expansion) device high temp, and we call anything in between the metering device and moving downstream back to the compressor, low temp. -you state the line in between the evaporator and compressor as warm, but the line between the condenser and metering device as normal, when in reality the line after the evap is usually 30-40 degrees colder to the other line and would never ever be warm.
Raymond that's great to hear we could help you learn the subject. Let us know if there's anything you would like us to make and we'll add it to the list.
When the refrigerant boils in the evaporater, that's because of the vaccum, right? Because the high side pushes and the low side pulls? Great video, by the way.
Just googled it to find the answer. TXV valve or the expansion valve is situated inside the evaporating unit and the sensing bulb is also near the outlet of the evaporation unit, so the expansion or TXV valve is in the my basement before the evaporation unit and sensor after the evaporation unit? The sensor measures the compressor suction line temperature and the expansion valve release the the refrigerant mix (80% liquid and 20% vapor) based on the temperature set on the expansion valve? It ensures the super heat temperature the compressor requires to function?
thanks brother...i seen all of you videos and its all very usefull for begginers and even for the technical expertise.looking forward to your new videos...great work
I like your videos nicely explained and well spoken, would you in the future or if you have posted a video of VAV boxes or old style pneumatic boxes? that would help allot keep up the good work.
Hi Juan, great to hear the feedback and I'll add the VAV to the list. We just made a HVAC video you might like also: ruclips.net/video/klggop60vlM/видео.html
Your videos are amazing, and it's ver obvious that you care about refrigeration. So, can you please generate a video about refrigeration by ammonia and please make it more professional. that we need information help us in operation, maintenance and basics of the cycle. Thank you again.
Great video.. however… you have described a “air conditioning system” the reason for this is when you mention refrigeration cycle but you clearly identify “warm” gas at a low pressure…!! As a 25+ year refrigeration engineer I would be worried with “warm” gas coming back to my compressor..!!!!
hi,Thanks for your clear explanation of Refrigeraton Cycler. I have one rather important question I would like to ask. Your Airflow where does the Air come from. Is it normally a Close Loop System where the Air is constantly re-circulated by the Evaporator Fan in the Fridge, or is Fresh Air Intake going on so that the Evaporator Fan is constantly pulling Fresh Air from the Outside and blowing it through the Evaporator Coils inside the Fridge. Also if it is not a close Loop System and the Fresh Air is constantly being sucked in from outside , is it vented out as it is recirculated inside and replaced by a fresh stream of air. Thanks
Great video information 👍❤ thank you for sharing your knowledge ♥️🇵🇭🫡 Please make a video how's it works HVAC condensing unit how's it works and parts and device. BITZER COMPRESSOR
Hi, I had an exam, and they asked a question that which part of the refrigeration recycle the temperature drops significantly, and I told "throgh the expansion valve." DO I ANSWERED TRUE?
Wait wait..why are you entering the condenser at the bottom??? Shouldn't it enter the top as a high temp gas, which cools and condenses to a low temp liquid as it descends (falls) through the coil? The low temp liquid then enters the bottom of the evaporator and boils off to a gas as it ascends (rises) through the coil. This direction minimizes the chance of liquid entering the compressor which would damage it. Or am I incorrect??
+suicide sponge on a simplistic level, yes it's essentially the same, although instead of a fan blowing air across the coils, a pump will push water across. I will upload a video soon for how a chiller works but in the meantime I recommend you watch our other video ruclips.net/video/1cvFlBLo4u0/видео.html "How a Chiller, Cooling Tower and Air Handling Unit work together" as I explain the process here and include a section view through the chiller.
hi -I don't understand 1-for the model T2/Te2 without third pipe from thermal expansion valve-when the valve are close the orifice -the presure wrere are going ? 2 the model with three pipe -third are conected at exhaust of evaporator -when the termic valve are close the pressure are going in bypass from third pipe ? And also who close the selunoid valve and the pressure of the compressor where are going ? the baypass are after this valve many thanks where I can find a animation of this ?
Thanks for the video. Could you edit the video to trim out the dead spaces when you’re thinking or not talking? They’re not really adding anything to the video and make it hard to follow.
No hate but a refrigeration cycle has 5 main components it starts with the comp then cond ten expvalve evap and then the pipes every system must have pipe work

I saw more than different videos to understand the basics of refrigeration cycle. This is the best explanation ever. Great work. Really appreciate.
Are you serious?? 🙄🙄
@@muhammeddilkas9983 yes. Seriously!
@@yashpatel3123 then you should watch more videos about this out there. They are more simplified and informative than this.This video is not worth it.
I absolutely love this channel. It is the best break down of everything mechanical
You taught me more than my professor was trying to teach me during her 2 hour long lecture.
Thanks for this video. It is really helpful. 💜
lmao sameee
What are u majoring in
Thank for this tutorial . Your video got me through a interview for a refrigeration tech ❤❤
This is why I love this channel easy to understand
Great video. Capturing the basics in clear and simple terms. thank you
Best Refrigeration Cycle demonstration I have ever seen! Excellent!
Has to be the most clear and easiest to understand thank you!!!
Even though English isn't my first language. I can hear your voice clearly. Thanks for this video.
Thanks . All your videos are easy to follow. Hopefully any new ones contain louder audio. I can only fully follow with headphones, which isn't a game changer, but would be nice to refer to these lessons anytime any place.

Please see the newer video, this one is old and terrible
@@EngineeringMindset I'll definitely check it out! Love that RUclips algorithm would send me an older video instead of the newer 😂😂
OMG! your explanation is the best one I have ever seen. I know nothing about refrigeration cycle operation....well now I do Thanks
Raymond that's great to hear we could help you learn the subject. Let us know if there's anything you would like us to make and we'll add it to the list.
Thank you this was very helpful
The best explanation stage by stage
Very nice explanation. Also good if you play video at x 1.5 or 1.75 speed.👍
Gem of a video. A treasure trove of a channel. Thank you!
his voice is really soothing :0
dude, thank you. easy to understand.
Thanks for your tutorial.... very well explained. Much appreciated.
Thank you soooo much, this is the BEST description I could have asked for!!!
Yes! This exactly what I wanted. Every other video sounded alien to me. Now after watching this they all make sense! Thank you!
I cringe at how bad quality this video is compared to our recent stuff but also very glad you still found it useful
just a wonderful way of explaining
Great explanation
It's really helpful to me. Thank you
Great explanation thanks!
When the refrigerant boils in the evaporater, that's because of the vaccum, right? Because the high side pushes and the low side pulls? Great video, by the way.
Thank you, vapor compression refrigeration
Well done, my friends! This is a phenomenal video!
Best explanation , Thank you!
Great Job there! please keep making such videos
Excellent, as usual.

Hey Mate....
Greetings...
ur doing a great job by passing ur knowledge to every one, i really appreciate that.
God bless u .

Hi Shadaab, really pleased to hear you liked it and it helped you. Plenty more videos to go up, stay tuned.
Man you're amazing.. Best explanation ever💪💪.. keep it up..
thanks brother...i seen all of you videos and its all very usefull for begginers and even for the technical expertise.looking forward to your new videos...great work
please louder the voice like other engineering mindset videos. barely hear it on outdoors with earphones but explains very well
Brilliantly explained thank you
Make a video on induction motor windings and its calculation
Very helpful, thank you.
Pipeworks upside down compressor should be at the top refrigerant flows down the condenser creating a high pressure sub cooled liquid
It's one of my first videos. See the newer ones. Not even sure how you found this
@@EngineeringMindset lolol please don’t take offense mate wasn’t a jibe was sending my apprentice some home work lolol

now i know how ac works!! thanks dude
Thank you
great video, appreciated
thank you for making this video i have i project i am doing and this really helped
Will you be posting a video for the cycle of a water cooled chiller system?
Hi Rashad, we have now. Please check out our videos! ruclips.net/video/0rzQhSXVq60/видео.html

BITZER COMPRESSOR
Hi, I had an exam, and they asked a question that which part of the refrigeration recycle the temperature drops significantly, and I told "throgh the expansion valve." DO I ANSWERED TRUE?
Thanks great video
Thanks
This video is more helpful on 1.25× playback speed !!
Location of expansion valve? Is it located in side the evaporator unit or condensing unit?
It's in the evaporator unit
Wait wait..why are you entering the condenser at the bottom??? Shouldn't it enter the top as a high temp gas, which cools and condenses to a low temp liquid as it descends (falls) through the coil? The low temp liquid then enters the bottom of the evaporator and boils off to a gas as it ascends (rises) through the coil. This direction minimizes the chance of liquid entering the compressor which would damage it. Or am I incorrect??
Expansion Valve
Third rewatch
Just noticed Expansion vlave. I laughed way too hard.
Nice
hi.how the refrigerant cycle work in a chiller?it is the same as video above?
+suicide sponge on a simplistic level, yes it's essentially the same, although instead of a fan blowing air across the coils, a pump will push water across.

The cycle is reversed
So I have a 5 and 10 year test to take for the pipe fitters union, and chance you guys know what to study up on or maybe can find a practice test?
Good luck Devin, recommend buying the official guidebook and maybe ask on some fitters forums.
nice, mate. niiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiice
7:003 How can a liquid be at high pressure? Liquids can't be compressed so they can have pressure.
Learn *HVAC FUNDAMENTALS* here: ruclips.net/video/klggop60vlM/видео.html
you should do your own courses.
wow it took me 10 minutes of watching to realise you misspelt valve
Shhh!

Thanks for the video. Could you edit the video to trim out the dead spaces when you’re thinking or not talking? They’re not really adding anything to the video and make it hard to follow.
what is throat valve
Dude used a mini split for real life examples 😅
Enters the compressor as a low pressure "warm" gas? No it enters the compressor as a low pressure superheated vapor... thats cold.
Low pressure, low temperature superheated vapor after leaving the accumulator if the unit calls for it
No hate but a refrigeration cycle has 5 main components it starts with the comp then cond ten expvalve evap and then the pipes every system must have pipe work
I'm more confused than before I started
Need to speak up in this video
Audio 🔊 quality is badd
Please watch you new video, this is very old version
je veut la traductiiiiiiiiion
nice break down but why are you whispering? lol
This is a really old video, one of the first ones I ever made. I don't know how you found this video but watch my newer ones, much better
🤨😒🤔😲😃👍
Please speak up!
lol, it’s fine
Turn up your device. It's loud for me
Didn't even watch this to quarter of the way cos I can't hear your speaking, you need to speak like you want people to hear what you got to say!
Just watch our newest content it's much better. I didn't even know how to make videos when I made this one it's so old.
