How A Typical Refrigeration Cooler Works - Pump Down Refrigeration in 3D

[@BBYERS27]

Bravo!!!! That was an amazing demonstration!!! I love The attention to detail. HVAC School always delivers superheated content!🔥🔥

[@jalenp8461]

These 3-D animations are going to help a lot more techs it is so helpful to see what is actually happening. I wish more schools would implement this

[@Swampdawgg69]

Thank you

[@PublicEnemy04]

As someone who is transitioning to Commercial Refrigeration from Residential Service, I highly, HIGHLY appreciate this. Thank you so much.

[@halverde6373]

Go all into commercial and industrial refrigeration . Leave the residential nightmare behind! You'll make serious bank. Either working for a company or on your own.

[@halverde6373]

Can you mentally handle 5 million dollars worth of product being lost or a nasty disease escaping the CDC if you fail? I have. Both times I fixed it.

@@halverde6373fuck yeah dude

[@JacobsNews]

​@@halverde6373even worse they're about to evacuate the dementia Wing🎉 and it's up to you to fix this unit that you've never seen before🎉 First Step spend 1 hour opening up ceiling accesses🎉 Step2 being told by the head nurse that it actually is in her office where you thought it would be but she assured you it wasn't 🎉 step 3 pray to the HVAC gods that the problems in the air handler so you don't have to go to the roof🎉

FINALLY SOMETHING FOR OUR VISUALLY LEARNERS MUCH APPRECIATED

[@MrJujubean]

I got into the HVAC in the mid 70s , I was in the commercial refrigeration side of our shop. We served malls and restaurants. Man if we would have had access to a channel such as yours I would have become a well-seasoned tech much quicker. You do a great service to our industry. Keep up the great videos.

[@bigclivedotcom]

That was a brilliant presentation.

[@Shade_Tree_Mechanic]

I agree. Great to see you here as well!

[@DawlessHouseMusic]

As a residential guy in refrigeration now, this was a big help. Had a bad first day thinking too much like a AC guy.

[@JP-sd2cw]

A visual video like this on for an economizer or even a safety circuit on a rooftop unit would be great!

[@jorgeuribe4512]

As someone who doesn’t know anything about refrigeration, this was an amazing explanation. It answered a lot of questions and gave me a big inside in case I ever have to do refrigeration

[@christopherbarrett6408]

As an operating engineer this is a great way of learning and educating video. Thank you once again

[@arbenitkryeziu46]

Just wow as a student of a trade and not understanding the teacher that much this is helping me sooo much, we need more like this 3Ds😊

[@DellAnderson]

Very impressive 3D animations. Thank you very much. You're helping explain a mysterious couple of installations using Hi Lo valves & Copeland compressors in an unusual highly customized application (bus conversion), so I have to understand deeply rather than follow a recipe in a book.

[@adlan8555]

I'm in Miami Appliance Repair technician. Mostly refrigerators. I want to become an AC technician. A lot. Best chanel!

[@FiercefoxProductions]

You mean refrigeration technician

[@acrservicesmathewr7565]

Wow I love these 3D simulators. You can’t get much more accurate then this. As a Hvacr tech I am new to refrigeration and becoming more knowledged in resisdential but the next step is commercial refrigeration. Thank you for taking this time to ensure we understand these presentations

[@SukhvarinderSinghBadesha1]

Best video on KZbin on the subject.

[@pabloaldo6683]

One of the best if not the best video explaining the Automatic Pump Down System, Thank you very much!

[@robertcherry4971]

Thank you I have begun to focus more on the commercial side as of recently. I have done this to expand my options and skill set. I appreciate all that you do for the HVACR industry…… GOD bless you all,stay safe out there brothers….and remember to never rush to judgment. Thank You!!

[@kirkprospector4958]

Keep up the great work brother :)

[@ebfsystem]

It will be cool to show how to troubleshoot the critical components on this systems, Great video!

[@dirkcanyow]

By far the most detailed video on how a pump down refrigeration works thank you. Keeeeeeeeep them coming

[@deundraiegrandison6287]

I just started in the commercial side and these videos are on points especially for someone green like me lol

[@realvanman1]

I'd wire those two 120 volt, permanent split capacitor evaporator fan motors to a series parallel contactor that runs them in series during the off cycle and parallel during the cooling cycle. Permanent split capacitor fan motors run very well at reduced voltage, running slower, consuming less power, and running cooler. This will save energy, and reduce the heat load on the system, while still providing plenty of air circulation during the off cycle.

[@911coldair]

I really appreciate the information you are putting out for the hvac community. Please keep doing this videos i love it.

[@alyciadh32]

THAT WAS AWESOME!!!! THANK YOU SO MUCH FOR THE VISUAL, VOCAL ILLUSTRATION!!! MUCH VALUED!!!

[@920HVAC]

Absolutely the best illustration available! Thank you.

[@steinarsaevdal6827]

[@curioushvacguy6876]

great video, really truly-- great job with he voice over work Corey

[@davem388]

I think I would be really cool if you made these type of animations to help people understand and read schematics.

[@EverythingHVACR]

I'm just watching again after sending it to one of our guys. I'm not sure if I commented before, but this is a great demonstration.

[@samalmo]

This is a great video and animation, thank you for taking the time to share this with the world, we need more technicians in this industry!

[@performancehvacr6629]

I love these 3D videos. Great, as usual. Nice work, guys.

[@zesty2023]

this is so good that even I as only a residential HVAC guy can understand it.

[@johnkurtz9304]

Fantastic! I wish these videos were around when I was in school.

[@WswRefrigeration]

You guys crushed it

[@takethe101totarzana4]

That was great. Thanks to all who helped put this together.

[@VileProject]

This is a fantastic rundown on pump-down system. Great job guys.

[@andrewtrushinski3848]

This was an excellent demonstration. Very helpful for me to understand better whats going on. I am also coming from residential air conditioning. Thank you!

[@waynenocton]

This is such a great video! I’m very new to refrigeration, but at my work we have so many issues with the many many HVAC units, and several walk-in coolers. We can’t seem to find anyone that can reliably repair the walk-in units, they either say the entire unit needs replaced, or they try and fail over and over again. Talking to them it’s clear they don’t actually understand them, which makes it hard to work on them. I’ve taken over the maintenance as far as changing filters, keeping condensate drains working and pans clean, replacing start capacitors when they fail etc, so basically I do what I can before calling for help, then watch and learn what I can. I have installed smart thermostats everywhere, since the employees like to turn some units to heat while others are set to cooling, and now have it automated so if one is changed to heat, all the others do as well and vice versa. But this walk-in is driving me crazy, it seems to want to freeze up every week or so, I have widened the temperature setting so it stays off longer between runs giving it time to defrost more, which seems to be working, and also have sealed up a few air leaks where new lines were run in and not sealed up which seemed to help a lot according to the temperature sensor I’ve installed which logs as well so I can see the patterns. But, what this video has opened my eyes to is the fact that the outdoor unit NEVER turns off! So I will be looking into that when I get to work tomorrow, thanks so much for your effort.

[@hvacmisadventures]

Make sure the door seals are good and leaving the door open for long periods will freeze it up too

[@puneetlakhian6728]

Omg! This is the coolest thing ever! Love the 3D simulations and there is so much good information in here. Thank you

[@tomwalton2872]

So cool no pun intended. I actually can comprehend that theory now. Thank you.

[@scottriddle5468]

That is how you show the proper operation of a medium temperature cooler. 🎉

[@zproxiimiity7733]

Best video out there on this!!!

Extraordinary teaching! Keep up the good work ❤

[@andrewluymes2977]

This is top notch video-what an excellent job!

[@HVACNoLife]

Great video! Hope you cover more refrigeration sytems. Would love to see low temp and modern EEV systems. You people are the best at education.

[@ulairecantea9231]

Great video. Thank you. It would be good mentioning that cut out at 5 psig is for reciprocating compressors and for scroll it has to be higher then 10 at least. Also for R404a refrigerant cut in of 15 psig is se to low and in most cases it goes in area 20psig and higher. Thanks again for amazing video.

[@austinburtch5972]

Wouldn't the Cut-in pressure be 80 psi and the cut out pressure be about 70 psi with 404a? To maintain a box temp of 36F degrees? Assuming you have to use a Pt chart to set the pressures on the pressure control. 15 psi is about -22 with 404a. Seems a little low for a box temp of 36F

[@ulairecantea9231]

@Austin Burtch thermosta in this case is regulating temperature in side box by closing and opening soleoid valve. It is set that way that remove most of refrigerant from low side of the system. If thermostat is removed then low pressure switch would be set differently.

[@austinburtch5972]

Oh yea lol I forgot about the t-stat in this situation 😂 I don't work on much refrigeration and the last one I worked on used the low pressure control to regulate the box temp not using a t-stat or pump down solenoid. Thank you for bouncing my brain back to Earth

[@colejc]

@@austinburtch5972 got me at first as well was just going to ask about that

[@Elisummit845]

Awesome video. I'm in the ac side of things but love to learn more. At 13:00 what's the point of the differential? Why not just have a cut in and cut out? I always get stuck at that (yes I have done small refrigerators when the customer asked).

[@Elisummit845]

Ok I think I got it. Because this is on the low side of the system so the compressor knows to come back on on a pressure rise. Correct me if I'm wrong.
