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.

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

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?

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?

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!

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.

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.

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.

Thanks for the video. Could you edit the video to trim out the dead spaces when youre thinking or not talking? Theyre not really adding anything to the video and make it hard to follow.

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?

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

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?

I saw more than different videos to understand the basics of refrigeration cycle. This is the best explanation ever. Great work. Really appreciate.

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!

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.

Pipeworks upside down compressor should be at the top refrigerant flows down the condenser creating a high pressure sub cooled liquid
