Another excellent video on how to break down the individual components in a supermarket environment. For those of you struggling with this video, break out your pen and paper and start designing your own piping diagrams, just like he did. If you are on the cusp of really getting a system running in your head, this may just be the "light bulb" video you needed. Remember, until you know what each component is designed to do AND why it is where it is, you won't have a complete picture in your head. Finally, make a point of watching properly operating systems. You can't troubleshoot a broken system if you don't know what it should look like when it is operating properly.
Thank you mia amigo for sharing your knowledge I just started to work for refrigeration company and it’s hard to understand rack cistern with your videos is helping me out.
Yes, this answered my question about the Hot Gas Bypass Valve. (Been struggling with that one for a couple weeks, but yes, there it is, literally in the last minute.) Thanks. [This goes a long way to adding knowledge of pressure and direction in these systems (!). The experienced guys already know this, but newbies don't - they get lost in the rack room when pipes get pointed to and we literally don't know which end is "up". This goes a long way to clearing it all up. (I should play this one every session the way musicians play the scales.)]
Man you are a treasure of knowledge, I been doing rack system for the last 10 years i can’t even explain the system even close to the way you did it in this 35 Minutes. Keep the good work, and Thank you so much Sir.
Super cool to see this and understand most of it 3rd year apprentice here and I spend most of my days in rack rooms or out on the sale floor deicing cases 😅
Great video information 👍 thanks for sharing your knowledge and experience 🫡🇵🇭, Ask questions ❓ how did you troubleshoot if one of compressor failed or how's the process? Is there a lead compressor if the system only need 1 compressor???
Excellent video!!! 5 stars! I am a little confused about the evaporator though. Comes in at minus 20 and leaves at minus 17 so it is 3 degree superheated vapor but it has increased in temp. So why is it still a vapor? Apologies if that’s a dumb question. It still stumps me.
I believe at that time stamp.I'm talking about the hold back valves. Those valves hold back refrigerant in order to raise the pressure in the condenser. If this allows the system to operate during low ambient conditions
Yes it does, The colder sections are lower pressure. High pressure wants to go to low pressure. There is a law of physics where high energy always moves to low energy. It's just how the natural state of things works.
I'm sorry that's a bit out of my wheelhouse, I have no idea. But on what I do know it depends more on how many systems are on the rack. For example I've seen a small rack Operate on a 200 amp service. But I've also seen racks operate on a 500 amp service. It really depends on how much Merchandising equipment The store needs. I hope that helps. But if the question is Is 600 amps enough for a supermarket I have no idea I have no concept of how much electricity in entire supermarket would use including lights computers all kinds of other stuff That might Be more Electrician or civil engineer. Good luck
You can think of it as they are all like 70% the same. They all use the same principles of physics to run and they have the same basic parts. And companies like hussman and Hill Phoenix have done a real lot to make their Refrigeration racks very uniform. But they will vary like 30% different from rack to rack. So for example a rack might be run with Emerson rather than danfoss. They might have asked for Extra Protection or extra pressure transducers or a larger compressor or one system might have a two-stage split condenser rather than a one stage. So most of its the same but you're going to have this 30% which might be called bells and whistles that will be added and it will change from company to company and from supermarket chain to supermarket chain. Hope that helps

Thanks for the comment good stuff
Thank you mia amigo for sharing your knowledge I just started to work for refrigeration company and it’s hard to understand rack cistern with your videos is helping me out.
Outstanding demonstration bro!
14.7 is atmospheric pressure anything under that is vacuum
Very good video great information thanks for sharing
Very informative! You know your stuff. Watching these to be able to land my dream job in refrigeration
Good luck!

Thanks I'm glad it help ya !! :)
Man you are a treasure of knowledge, I been doing rack system for the last 10 years i can’t even explain the system even close to the way you did it in this 35 Minutes. Keep the good work, and Thank you so much Sir.
I'm impressed. That was a great overview!
Thanks :) I appreciate the compliment
Great explanation of all the components and how they work! 👍👍
Thankyou :)
LOL "comes in here out their around here and up around this valve that valve I love your knowledge and confidence ect:
Thankyou :)
Great video
Super cool to see this and understand most of it 3rd year apprentice here and I spend most of my days in rack rooms or out on the sale floor deicing cases 😅
3rd year apprentice my company throwing me out on my own I told them at least give me a year
Thank you for your Video,
again, really appreciate you, i'm already leaving out my er's and replacing them with ah's
🤣
Awesome video 🤙
That's awesome all the way until the end !!
Nice video
Awesome
Thank you sir
Great video information 👍 thanks for sharing your knowledge and experience 🫡🇵🇭,

How's the process for oil charging or refrigerant charging or replaced of parts?
Excellent video!!! 5 stars! I am a little confused about the evaporator though. Comes in at minus 20 and leaves at minus 17 so it is 3 degree superheated vapor but it has increased in temp. So why is it still a vapor? Apologies if that’s a dumb question. It still stumps me.
It comes in as a liquid.
Heats up 3 degrees.
Now it's a vapor.
I hope that helps:)
21:31 The check valves will prevent the 80% liquid that’s being held back. From going back to the split valve and w.e is being reheated right?
I believe at that time stamp.I'm talking about the hold back valves.
Those valves hold back refrigerant in order to raise the pressure in the condenser.
If this allows the system to operate during low ambient conditions
Refrigerant moves from warmer to colder?
Yes it does,
The colder sections are lower pressure. High pressure wants to go to low pressure.
There is a law of physics where high energy always moves to low energy. It's just how the natural state of things works.
Min 32:00
Couldn't quite grasp the last 2 minutes... Is this about Hot Gas DEFROST?
Yes it is :)
It's how the hot gas works I'm glad you watch to the end.
Was it helpful?
@@gendronhvac-r1269yes sir thank you
Is 600 in enough power for a 22000 square-foot supermarket
I'm sorry that's a bit out of my wheelhouse, I have no idea.
But on what I do know it depends more on how many systems are on the rack.
For example I've seen a small rack Operate on a 200 amp service.

But if the question is
Is 600 amps enough for a supermarket I have no idea I have no concept of how much electricity in entire supermarket would use including lights computers all kinds of other stuff That might Be more Electrician or civil engineer.

Se ve muy sucio no hacen servicios preventivos
Im glad I'm not sitting in an office designing this stuff,I like to use my hands.Are most all rack refrigeration systems to same?Thanks

Is 600 amps enough power for a super market
Depends on the size of the store and what all it has.
It depends on the size of the store.
But I have found many racks that are under two hundred and fifty amps
Awesome
