Great video! Quick note though…how I understand the receiver level indicator is that when it says 100% full on the indicator the actual level is about 80%.
Helping those who are willing and ready to learn new things is the reason I do these videos. I got pushed to the back of the line and overlooked my whole career. Never give up and never give in, if you want it bad enough MAKE IT HAPPEN🙌
That's a great video! You always learn something new on these. Especially neat seeing the dynamics of such large scale systems that you just don't see on more common equipment... Thank you for taking everyone along!
Rick you did a great job especially on some equipment you hadn't worked on before . Now something tells me you're gonna get yourself the 400 model of the plier-wrench 😏
Love my can of degreaser to clean valves like that. Only issue is you have to pull a vacuum following, love me some nylog for assembly even on bolts. Great work
Probably why I like your videos so much, I am that type of guy. Being a Millwright, I just like seeing how thing work. Your vids are great , keep up good work.
I like when you can use the system as a recovery tank after years have to drag heavy tanks on the roofs it’s really nice to just drag a small recovery machine up lol very good in-depth video Rick
I always have a tube of Permatex One Minute Gasket Maker and Loctite 515 Gasket maker for those situations, both work great in sealing a flange if that gasket is worn/incorrect.
@@HVACRSurvival The minute gasket maker dries within 15 mins (Even though it states 1 minute). The loctite 515 I am not sure, I have put back together parts and let it sit for maybe 5-10 minutes before tightening a flange down and it seems to have held with no problems so far.
I did a poll and more than half the country want to see live streams from you , Lora and friends ... Just sayin' and I only report what I hear 🤣😅😂 Thx as always ...
I was going to do it this weekend but I was on call, plus I couldn't get the videos made quick enough, I spent all Saturday cutting that long hour video down to 25 minutes. I just got a go pro 11 and I'm learning to watch my settings closer than before. That can kill the picture quality.
I worked on this one hour video all day since about noon. I don't think recording nonstop is a good idea 🤣. I appreciate the kind words, there's plenty of things I need to get better at. Grocery stores are one of them, chillers even more so.
Never worked on any supermarket before....about the only side if the trade i haven't experienced....probably won't at this point in my life. I enjoy heavy commercial and industrial. I especially enjoy the hydronic side. Chillers and boilers are my jam. As always another great video Rick. A true professional
Grocery is a hard market to get into. There are only so many grocery stores compared to regular business and residential. I've been finally getting my chance to do more chillers just recently. It's been a slow transition into industrial and racks.
Thank you, it makes a lot more sense, when you can actually see what is inside the housing. Those commercial systems are neat, having that valve to allow you to block off the High Side, while you evacuate the Low Side.
That's how I feel as well. If you follow my Instagram page I posted a valve three times larger and has two pipes in and two out. It's interesting how they cut the sliding piston to direct the flow.
yeah cant really gauge liquid when running in split, also when you want lower pressure you can go to the controller and override some compressors on to get your pressure low enough where you like it and then valve it off well at least thats what i do
@@HVACRSurvival winter time has a lot of liquid stacking and VFD issues over here where its condensing too quickly and there is not enough liquid coming back to receiver so just make sure all your discharge pressures are near your float setpoints it will cause a lot of issues, floodback to compressors due to not building enough differential, not enough liquid going to some cases ect.. subcooled liquid should never be lower than 55 degrees anything lower and you are just wasting energy and refrigerant due to being subcooled refrigerant is more dense and can not doing much more than 55 degree liquid but being subcooled you can down size your valves for load for increased capacity from efficient subcooled liquid, not sure if it helps but just throwing it out there
No, it helps to hear it, there's a lot of times you know the principles but until you see them in action you don't really put it all together in full coherence.
I've lost my trust in those rebuild kits. Seems like I always get something different than what I should have. Unfortunately, I've transitioned to just replacing the valves. Seems to be a more consistent fix. Nice video 👍🏻
So how do you pull a vacuum on something that immense? Many pumps for sure but what about a micron reading? Because that system is huge, is an initial vacuum of 1000 microns even possible?
Sure it is... when it's new. The problem I find is overtime there are several little leaks, in the valves, braze fittings, trapped refrigerant in the oil. Several little things add up. All we can do is do our best with the time and equipment we're given.
Everything can be pulled to a sub 100 micron vacuum if the system is tight and you bring enough vacuum pump oil and have enough time. I know guys who have made repairs to chillers and had to leave the pump on for three days straight, returning one to two times a day to change the oil. Pulling a vacuum slowly is infinitely better than pulling one fast. A fast vacuum can freeze moisture. 🤷♂️
@@HVACRSurvival I am not sure but the entire super walmart lost all refrigeration with exception of some individual floor units. The said it was a leak. So I was wondering what would cause such a huge failure in all freezers and fridges? It just seemed odd to lose so much and not from power issue but leak.
Great video! Quick note though…how I understand the receiver level indicator is that when it says 100% full on the indicator the actual level is about 80%.
That is correct, You should only fill it no more than 80%.
Love seeing work from the supermarket, makes me wish I did more work in the supermarket
Appreciate you opening and showing how everything works, really helps us newer young techs out.

🤣👍👍 anything bigger than the 10" gets crazy money.

Thanks so much!
That system makes my head spin! Definitely takes experience to work on one of these.
Love riding along on a new experience with you!
Awesome!
Baddazz video...I am refrigeration but I ain't done one of them yet.
Thanks brother 👍👍

Thanks for the support and the feedback, they help a lot🤜🤛👍👍
Awesome video as always. Being diversified in multiple sides of hvacr is a plus.
Very true👍👍
Nice one Rick
I like when you can use the system as a recovery tank after years have to drag heavy tanks on the roofs it’s really nice to just drag a small recovery machine up lol very good in-depth video Rick
As I get more hands on time with the larger systems I'll be looking into a longer 3/8 liquid hose.
I always have a tube of Permatex One Minute Gasket Maker and Loctite 515 Gasket maker for those situations, both work great in sealing a flange if that gasket is worn/incorrect.
I have used something like that on steam traps, how long does it have to dry before using it on high temp and pressures like refrigerant?
@@HVACRSurvival The minute gasket maker dries within 15 mins (Even though it states 1 minute). The loctite 515 I am not sure, I have put back together parts and let it sit for maybe 5-10 minutes before tightening a flange down and it seems to have held with no problems so far.
@@saugatools402 it sounds like something good to have when you can't get the gasket right away👍👍 thanks for sharing!
I don’t do the service but I do do all the piping and brazing on equipment like that. I understood all of it lol
You're at a greater advantage than I was just when I first started doing these grocery stores. I'm still learning everyday.
Wow those Allen screws are some kind of tight

@@HVACRSurvival Oh I went and looked below video and was very impressed how you had it laid out. Looked like a ton of work.
Great job Rick, Making amateurs and rookie technicians look bad again, as usual. Keep up the good work.
I hope these videos give you a helping hand. My goal is to be remembered as someone that made it make sense.
Nice work Rick. Always learning from your videos.
Thanks for the support!
NIce how you admit and show your mistakes. A lot can be learned from mistakes.
That's how I have learned most of what I know, by seeing what happens when you try something and see the result.

I feel you, I can't believe what they sell for $$$
@@HVACRSurvival agreed. Prices on this stuff has been blowing my mind.
Is the big copper just resting on the uni-strut without any isolators right next to the bypass valve?
Can you reply back with the time stamp that way I can find it please.
Sweet deal.
Thanks John!

My local Walmart lost 90% of all freezer and fridges twice, not sure what failed. Is there one loop that would cause that?
What do you mean by "one loop"?
@@HVACRSurvival I am not sure but the entire super walmart lost all refrigeration with exception of some individual floor units. The said it was a leak.

🇺🇸💪❄👍 thanks Obi-Wan
🤜🤛🙏🙌 thanks for being a great supporter bud!
@@HVACRSurvival thanks for being a great teacher of the trade. 👍🙏
👍👍👍
what is the leak detector you used?
Inficon Stratus. I did a review video on it vs it's little brother the dTek3.
I bought the Stratus after chatting with Rick for quite a while.....it is worth every penny it costs.
Tell them how it is lol
