Grocery Refrigeration - TXV & Oil Failures How To Fix

[@mxcollin95]

This is the first time I’ve seen a commercial system…pretty cool. 👍

[@HVACRSurvival]

I have more under my grocery video play list.

[@marvinsellers4457]

Man I’m always so impressed by your work it’s so enjoyable to watch and learn . Thank you. Captain

[@HVACRSurvival]

Thanks brother. I appreciate that!

[@GreatValueVarget]

Ahhh glad to see im not theonly one who thought it was supposed to use one O-ring, fought with a leak for about an hour last week.... Instructions on the pot say they're supposed to be doubled up with a flat rubber and a o-ring rubber. RTFM gets all of us esp when you throw the box away lol Edit: few minutes later i see you found out the same info heh. Stacking 2 orings worked nicely for me (totally not because i couldnt find the second flat one that came with it or anything) Also, a dab of nylog keeps those things in place nicely while youre snugging it all up

[@HVACRSurvival]

It’s crazy imo , one flat and one round o-ring to make a seal 🤷‍♂️🤦🤣👍👍

[@throttlebottle5906]

when in doubt double it out? lol it make sense to have a wider flat surface are against some things, they could possibly make a special gasket for it, but cost cutting has them using off the shelf items.

Good job Rick....You're getting better at commercial maintenance...... No carriers today........

[@gabesreef]

Love these videos. Thanks for making racks easier.

[@HVACRSurvival]

I’ve been there, still there at times.

[@SupermarketRefrigeration]

Probably my favorite racks right there. United sells the tools for those solenoid stems. Theyre called "expansion valve adjustment discs". They look like a brass coin about the size of a half dollar. Nice work as always 👍🏻

[@HVACRSurvival]

Thanks for the info! I’ll find it on line hopefully.

Respect 🙏 Fantastic professional great quality work Rick 👌🏻🤟🏻

[@HVACRSurvival]

Thank you!

[@davidsanders6957]

I really enjoy seeing a skilled technician, as I'm one as well, I get you & scope of what's going on. You should be an instructor dude.

[@HVACRSurvival]

Thank you very much!

@@HVACRSurvival I've been watching your videos now for a few years, I myself am an HVAC technician and I'm definitely learning from you. I'm a 20 Year technician and love learning new things by watching the content. Keep it up 💪.

[@HVACRSurvival]

Thanks man. That makes my day. I don’t think I’m anything special, I just think I have learned a few tricks that I like to share.

Excellent video

[@fshn76]

Good video Rick. I strive to braze as good as you someday. I can get it done but they are usually not the prettiest. Hope you had a good weekend.

[@HVACRSurvival]

Thanks, you too! Clean is the key and the right amount of heat.

[@jasonjohnsonHVAC]

Supermarket is the only side i haven't experienced in this trade. It does seem interesting.....but that on call is whats kept me away. I enjoy learning about it and the videos.....I like working on chillers and hydronics....so as the kids say....I'll stay in my lane. Thanjs for sharing big dog

[@HVACRSurvival]

I still need to get more experience on the chillers. We have them, but he can only learn one thing at a time. Otherwise, I feel like I’m just half asseing my way through it.

[@jasonjohnsonHVAC]

@HVACRSurvival they take some time, especially water cooled and more specifically...centrifugals. I have no doubt you could be just as good at it, as you are aspects of the trade

[@HVACRSurvival]

Thanks Jason, I’d like to meet you, maybe we will be at a up coming show somewhere. Your one of my biggest supporters 🤜🤛👍👍

Anyyway to see your everyday carry ? ( toolbag ) love your content !

[@HVACRSurvival]

Yeah, I might be able to do that. I’ve done it on some other tool bags from a few years back.

[@chrisconklin873]

You have to put both seals on the sight glass and regulator mating surfaces, that's why there is 2 different styles of seals. The o ring seats inside the other seal

[@josephconway1968]

Great video, Rick! 🔧🔩⚙️🪛🧰

[@HVACRSurvival]

Thank you! 🙏

New Rick video 🥳

[@briankobes8208]

I have cracked a sight glass before using only 1 o ring . Got a new glass and used 2 rings

[@terryh8421]

Always enjoy your video's Rick.

[@HVACRSurvival]

[@MICLGz]

What don’t you work on lol. I’m just now getting into racks now……a lot of stuff to learn.

[@HVACRSurvival]

Yes there is. But you’re worth more money the more you know. 🤓

[@jonnyjonnyyespapa8013]

2 gaskets for the sight glass. Quarter goes on oil float body and round goes into sight glass portion

[@garypoplin4599]

13:07 - Rick, you added 15k to the SST. Some say 10k, others, say 20k DTD on refrigeration equipment - still others, 15k as you did. Is that just RoT, or is the design temperature difference for different equipment written anywhere so I can get more precise guidance than someone’s guess?

[@HVACRSurvival]

That’s just rule of thumb. Design could be 10 or 15 on the old stuff.

[@davidsanders6957]

You THE MAN, man.

[@HVACRSurvival]

🙏👍👍🤜🤛

[@D_Nice981]

I used to always double gasket the sight glasses whenever I replaced the sight glass on an oil regulator never has any leaks

[@sterlingarcher46]

I just read the comments about the gasket now I understand better , but 2 different gaskets on top of each other ? Wouldn't have thought to be honest. Although I've seen even weirder : Teflon gasket inside a groove goes against " Klingerit " flat cardboard like gasket... Go figure !

[@HVACRSurvival]

I was afraid to do it that way cause I thought that was Jerry rigging it. Come to find out that’s how you do it.

[@bradsmith9293]

There is a grooved ring gasket and a regular ring gasket. The grooved ring goes onto the sight. The other goes into the groove of it and against the compressor. Tighten

[@LifeisAmazingify]

Where did you get that bucket lid organizer from, been looking for a good one for a while

[@ayoutubewatcher7009]

I think Epr valves are mainly used for hot pull downs, as to not overload the compressor. As always great work.

[@chrisconklin873]

wrong

[@HVACRSurvival]

I see more CPR valves used for that. Thanks for the feedback.

[@andyread4332]

An EPR will hold pressure in the evap to maintain SST.

[@topher8634]

They are used on racks that run low and medium temp boxes. The controlling pressure is set to the low temp setting and the EPR will keep the compressors from pulling the pressure down to that setting so that you maintain a warmer evap. Without it, the pressure would be pulled down too low and the TXV would not be able to keep up.

[@topher8634]

​@@HVACRSurvivalthat's right, I think he's confusing the two.

[@whiskey7104]

What do you guys charge an hour just curious for grocery stores? And this is a general question anyone can answer. And also survival do you work on chillers at all? Nothing crazy like water cooling towers or even small chillers for a small complex. Just want to ask for myself and the way I’m growing on what I’m doing Thanks for anyone’s insight.

[@HVACRSurvival]

I work on chillers just not a lot right now. hourly rate is subjective to the area you live in. People would laugh at how little we charge compared to big cities but in our area, it fits the market. I don’t talk about the price.

[@hvactech77]

Just a thought but can u flip that sight glass to use the smooth side in ur application. Not sure if would matter flipped. It’s just a sight glass.

[@hvactech77]

I would have kept the sight glass flipped. No biggie.

[@HVACRSurvival]

I would have but I can’t show someone to do it wrong once I knew how to do it correctly. My moral compass said no. It only took 20 minutes to do both.

[@LifeisAmazingify]

I have double gasket those sight glasses and it held

[@thomweg6468]

Are you working on newer racks too? I really only work on racks an most markets in europe were I live build the whole Building new every once in a while (20years~)

[@HVACRSurvival]

I wish I worked on newer stuff. There’s really no grocery stores around me other than Walmart and Myers.

[@thomweg6468]

@@HVACRSurvival Ah ok that sucks. Yes most markets are not so big like Walmart but rather 10~ Normal (like you had in the Video, don't know the english word for it 😅)1-2 Cooler and 1 Freezer and about 5~ Freezer. But the New markets only run with R744, both normal and freezer.

[@thomastimmerman42]

everytime i have done a compressor and oil pot there is a double oring on sight glass one on pot side and sight glass side

[@HVACRSurvival]

I know that now. That was only the second one I’ve ever done.

[@throttlebottle5906]

probably should have pulled the strainer/nut with gasket out before brazing and maybe the bottom cap/adjuster stem. no gaskets to cook = no worries.

[@danpresson]

Rick your amazing great video

[@topher8634]

Ive always called it an oil pot too, nothing wrong with it, IMO

[@HVACRSurvival]

Thank you!

[@850EstatesEnterprise-n6q]

Got to use two gaskets one with the slight grove in it and one regular the one with grove goes on the canister the other on the glass cover

@@HVACRSurvival I’m currently streaming your videos you do shit to the T keep learning we all don’t know we very thing. You got every tool to test everything love the start up tech mentality.

[@WaffleStaffel]

My grocery store has banks of water cooled compressor/condenser units in large boxes, about 3x3x7 throughout the store on endcaps and whatnot. Anyone know what they're called? They're super quiet. I saw one of them open once and it looked like it had an enormous scroll compressor with like 2 inch suction lines, if I recall.

[@SupermarketRefrigeration]

Likely Protocol Racks made by Hussmann.

[@WaffleStaffel]

@@SupermarketRefrigeration Thanks! Yup, that's what they are.

[@WaffleStaffel]

@@SupermarketRefrigeration Huh, I assumed they were water cooled because of their location, but it looks like most system have rooftop condensers. What would be the advantage of locating _just?_ the compressors in cabinets throughout the store?

[@SupermarketRefrigeration]

@WaffleStaffel depending on where you're at in the country, they could be water cooled (Evaporative Condensers). If you're in an arid climate there's a good chance they're using those. The only real benefit is the money savings on not have to run a bunch in line set to the cases. If the racks are right next to the cases then you have a lot less line set to run.

[@HVACRSurvival]

I only have one store with the Proto-call rack. It’s a great unit when it has the electronic APR valves at each case.

[@throttlebottle5906]

wait, what is this no digital gauges!(lol)

[@scottdavis6717]

Please don’t put sight glasses on backwards. It’s a square cut with a concave ad a o-ring. When the glasses are backwards you cannot see the oil level..

[@HVACRSurvival]

At the time of it recording I didn’t know what the correct seal pattern was, once I did then I did it correct.

[@anthonyking5211]

You,re supposed to oil the o rings on the cart

[@HVACRSurvival]

I used nylog, that’s made with Refrigeration oil

[@throttlebottle5906]

"where's my youtube police at" 🤪 woop woop, wheeeeeew. all the times i;ve been pulled over(in the past) most either never hit the siren or just blipped it, the lights were enough. i guess the stacked gaskets would make a better seal overall, giving more pressure to a smaller area and secondary seal over the larger surface area.(especially if overtorqued) maybe some measure to keep site glass/leakage down if overtoruqued? likely a cost cutting measure too, while a custom flat-raised ring gasket would likely be best, they used off the shelf schmutz to do the job. I'm speculating here. pull it on over bro. 🥳🥸 **edit, actually, the glass/seals/small ring may be pressed into the large outter steel ring and also why the square cut ring is there to additionally seal that area, and the flat gasket to seal the large ring to oil pot body. reversed like that it may blow out the glass, seals and retainer ring! sometimes it takes me more thinking to reverse engineer on the fly nd I need to slow down, you seem to have the same mentality and figure things out well and plenty fast.
