"we're not taking hot air out of the house, we're taking heat out, the two air flows are separate" This immediately helped my understanding of the cycle.

PHENOMENAL EXPLANATION. Anyone working on Automobile A/C would benefit from this!

Excellent explanation, it was refreshing.

This has to be the Best description of a refrigeration cycle I've seen (seen many). Easy to understand, plain and sensible use of English, organized and good flow, fast, etc. No adiabatic, enthalpy, and other complicated terms that distract. Good job! Thumbs up

I am someone who is just getting in the HVAC-R trade. I have been going on ride alongs with a company and the gentian I've been learning from has been teaching me this process. After watching this video it all clicks to me! this is one of the best teaching videos I've watched. Thank you.

This video made abundantly more sense than the semester of Thermo that I sweat through (no pun) in college! Thanks for a great explanation!

Left handed guys are always very intelligent and smart , keep uploading boss

Great educational video and training. Thank you

He is a very good teacher!

The best I've seen. Thanks

Excellent video, this is the right way to teach the refrigeration cycle to new and prospective hvav technicians!!

I have been watching many videos, I heard the superheat/subcooling over and over. With the explanation here, all makes now sense. Thank you, thank you.

Outstanding explanation, thank you. No thermodynamics gobbledygook, no entropy mayhem. Just Boyles Law . Thanks so much

2 minutes into the video and this has been a great video to learn from immediately 💯💯💯

Great presentation Jim Bergmann, clear explanatory overview. thank you !

Hi Jim, wanna say good job in putting up the video in simple and detailed view of the Vapour cycle air conditioning syste. Appreciate that

I'm studying 5th Class power engineering here. I'm already a plumber, so I've got the boiler stuff down pretty well. The refrigeration side though, is the next largest part of the provincial exam. I know very little about refrigeration. This is the best video I've found yet. Thanks

you're the best JIM, thank you very much.

Best explanation of a refrigeration cycle ive seen yet!👍🏻👍🏻👍🏻👍🏻...Thanks

Most outstanding! Great video. Explained thoroughly and clearly plus you covered a lot of pertinent details like in/out temps for evap and condenser. Plus it is the first time I have ever seen that explains how the evaporator keeps liquid out of the compressor. Thanks so much

Thank you. This is by far the most comprehensive explanation I've ever seen in youtube about Air Conditioning cycle....

This was extremely helpful...I've watched a bunch of videos and your video was able to give me clear understanding. THANK YOU

By far the best video I have seen as well. You made the refrigeration cycle make so much sense. Thank you

Really appreciate this video. Thanks for making the basic HVAC cycle understandable. Well done.

Best presentation EVER. THANKS

Awesome explanation!!! Simple and to the point!!! Someone give this guy a raise!!! Thank you

Thank you for this. I was somewhat confused based on what my class was telling me. You made it pretty straightfoward.

Very helpful. Needed to refresh my understanding of the cycle and this was very well done.

At last! I understand it. Brilliant. Many thanks.

Explained this way better than my instructor!

Excellent presentation. Thanks!

Thanks for the simple explanation, now I have a good foundation to build on. Especially the metering device was always a difficult explanation to try and sort out, but you did it for me. Thanks again sir

Great explanation. You couldn’t of explained it better. Great job Sir

Great Job! Helped me out on my last min exam prep.

Great job Jim!

This is a great video and fantastic explanation of the refrigeration cycle.

Thanks, you have the most accessible presentation of the basic refrigeration cycle.

The best instruction so far!

Thankful to you for for this awesome overview, free of confusions. Could u do more videos & spread your knowledge & use board like this one?

Dude! This is awesome! Thank you!!!

i been trying to under stand this for the past four week and for the life of me i could not get it at all... but this video help me in just the 1st watch... thank you alot sir

Wauy this video is amazing, they way you express the circle is perfect great video boss 💯🙏🏽✊🏽

Thanks in a million. Great content. Awesome. Grade: A++💥

Excellent, concise, and clear.

Great Video!

This is an excellent video. Thanks

Excellent explanation!!!

Great video could you do the same video for adsorption system? Your explanation is very clear. Thank you.

Thank you sir .. wonderfull overview🙂

You'd think I'd understand superheat and subcool by now, but I didn't until this video! It's just the temp above and below boiling point, now I get it! I still view the refrigeration cycle as the closest thing to real life magic I know besides flight.

THANKS FOR GIVING A VIDEO IN THIS TOPIC, IT HELPS FOR MY COMETATIVE EXAMS

not all heroes wear capes

Thank you for this great explanation.. really helps

Great explanation

Great video!

This was well presented but it contains one flaw common to every refrigeration cycle explanation I have ever encountered. The job of the compressor is not to increase the pressure; its job is to increase the temperature. It accomplishes that job by increasing the pressure. I believe that one of the reasons so many people struggle to troubleshoot refrigeration systems efficiently is because of this inappropriate elevation of the importance pressure change in the cycle. Of course, it is important but the job of a refrigeration cycle in an air-conditioning application is to absorb heat from cool indoor air and shed it in warmer outdoor air. The heat absorbing coil must be cooler than the indoor air it is absorbing heat from, and the heat shedding coil must be warmer than the outdoor air it is shedding heat too. To do this it would be obvious to the student that there has to be a mechanism in the cycle to make the outdoor components warmer than the indoor components. To me it makes more sense to explain that this is the job the compressor does, raise the temperature, and to explain that the metering devices job is to lower the temperature. Then explain that the compressor raises the temperature by raising the pressure and the metering device lowers the temperature by lowing the pressure. Temperature change is PRIMARY, pressure change is just the means to that end. The refrigeration cycle contains five basic components: a heat carrier (refrigerant), a heat absorber (evaporator), a temperature increaser (compressor), a heat shedder (condenser), and a temperature reducer (metering device).

Very good, thank you!

Great video, thanks

it was very informative sir!!! well done

Great job sir!

Very helpful thank you. Can u please do a video on water chillers and/or cascade and booster systems

Very good explanation, thank you

Excellent presentation.

Good job sir

Very good!

Thanks from India

Do you know if there are videos of some one going through the system. like you do here except with different faults and how they affect the system? It would be tremendously helpful to people how are visual learners.

Awesome explanation, Thx

Can you do a similar video on the heating process and furnace

Thank you for your this study i think it had done useful a video

Great presentation

How does a fridge work? Me: Yes Best Video on KZfaq on refrigeration for dummies (me)

best explanation

Thank you thank you thank you

Thank you for this video. Originally the blue gauge showed the saturation temperature of 20 degrees F (Pressure 43 PSI R22). At the same time the temperature I measure on the blue line next to the charging port is 80 degrees F. Thus my Superheat is 80 F - 20 F = 60 F. The pressure at the red gauge before charging was 200 PSI that corresponds to the temperature of 102 F. When I charged the system from the R22 recovery bottle, the Superheat changed 75 F - 26 F = 49 F. my red At the same time my red gauge after charging shows the pressure 225 PSI or it is the temperature 106 F and I measured the temperature of the high pressure pipe was 106 F. Question- is my system is overcharged now of I should continue charging it?

Best soooo far ❤🙌🏻🙌🏻🙌🏻

Very informative

When you type HVAC/R online Jim Bergman’s face appears not all hero wear capes he’s the real MVP

Thank you sir..

thanks you so very much

excellent.

Damn good

hi,Thanks for your clear explanation of Refrigerator Cycle. 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

Very good

Legend

I understood this.

If the office is small, the pressured supposed to raise, so I think!

Nice tutorial. One question, is the Evap fan is using 75 degree air across the coil ? Is that like at 1st start up ?

Thxs to you sir

Thankyou..

I was so confused in my class prior to this

thank you for the video but I still don't get how the heat is remove from inside the house? is thru the evaporator coil ? but once you remove the hot air from the inside the house and supply 55 degrees what happens to the heat? where does it goes?

thanks

Please explain about liquid receiver how it works.

Have a side by side KENMORE FRIDGE, THE FREEZER FREEZING BUT THE FRIDGE NOT COOLING NO VOOL AIR COMING THROUGH THE AIR VENT INTO THR FRIDGE. COULD SAY WHAT'S THE PROBLEM?. THANK you so much.

In the above example what will be liquid line temperature

Am A/C man for 30 years now am now in d US but not no woh to reed or right

Is the condenser removing the indoor heat as well as reducing the temp of the refrigerant from the compressor.

well put
