Supermarket Refrigeration - How to Leak Check a Parallel Rack System

[@dr9759]

Doing my first solo PM leak check this Sunday 😁 you are about to make me look like a pro. Thank you for teaching the younger generation bro 🙏

[@businjay]

so fascinating watching your videos. as a kid my grandma worked at a small town grocery store and I loved when she took me to the motor room, was an old r12 and 502 system at the time, was soo cool. I dont get called to work on this kind of stuff in my HVAC biz but its fascinating, I went to an auction at a decommissioned king soopers store a few years ago just so I could see the motor room, There are nerds like me who love to see this stuff so thank you for sharing!! Not alot of people realize the complexity that goes into keeping their totinos pizza frozen, Thanks again buddy :-)

Nice video, i leak checked a rack and forgot the headers i have to go back to finish tomorrow though

[@OleRazzleDazzler]

hey brother, maybe you should mention that this method only works with heated diode detectors. Great video. love your shit

[@zombiediarhea]

Seems like if I start in the motor room, i wind up running the battery dead on my H10 trying to tighten schraders and caps on the fly. It's an awesome leak detector though.

Very informative video. Just subscribed. Love this channel. Thank you so much. Retired HVAC mechanic

[@gendronhvac-r1269]

Thanks :)

[@zombiediarhea]

So glad to find a channel that was created for the field of work I'm in.

[@gendronhvac-r1269]

I'm glad to help :-)

[@maheradous9257]

Very good job brother

[@hvacrnortheastern2110]

Great video this reminds me of the Supermarket chain that designed with header & receivers most of time are outside l know what store your in l use to service them in-till they move out of our state going back about 20 years

[@gendronhvac-r1269]

Thankyou :)

[@rocker8692]

They should make freon with infrared dye,and you put on special goggles and could see a leak.

[@dioncurtiscurtis3188]

No the outside is a must😂😂 if found a crazy blow out in a ff case, from pipes rubbing together.

[@lwilton]

Thanks! That seems like a really good overview!

[@user-uw6jh4cr9z]

Right every store has a refrigeration map to look at. The racks we do leak on every valve, every control and every fitting. We stopped looking for leaks.

[@gendronhvac-r1269]

Yeah, sometimes it's hard. A lot of stores are not willing to commit to a full leak reduction. Few of our customers refuse to pay us for leak reduction services. And they got into really deep trouble with the e p a. Only so much you can do as a technician. God bless my friend

[@cosminmunteanu2603]

Thank you !!!!

[@DonutsRGreat]

I don't know if it's common where you're at, but those water heat reclaim tanks have been leaking like crazy up in new england (thermostors)

[@gendronhvac-r1269]

Yes they leak a lot.

[@zacnadeau338]

Fellow new englander!

[@flynnnixon1246]

Great video thanks! 13:30 lol

[@carlocurotto7555]

Great video mate

[@mauikawi4290]

excellent content bro.

[@timothysambolin5293]

I’m in the field,I get stuck sometimes with oil issues,and I try to pump down the system to try to bring some of the oil back to the reservoir and I’m not sure where exactly to pump rack down. I would love a clarification on where to do that. Can you make a video on that?

[@gendronhvac-r1269]

kzbin.info/www/bejne/l6eUdpeIn5mSbM0 This I feel like might help :)

[@keepnitkool9042]

Where in New England are you? New Hampshire boy here!

[@austinhiggins6799]

Im getting exhausted just watching this video. Leak checking racks sucks

[@ryanellinger103]

Receiver should have liquid in it at all times. Industry standard is 20%, yes customer specs are all different. Running below 5% really means you have no liquid, because the handson rod are never 100% right.

[@gendronhvac-r1269]

Thank you for your comment you're a hundred percent right we should be running at 20% :). But it's what our customer wants so they pay us we're paid to do what they want lol. So there's really not too much we can do. They will try not to pay us if we go over the amount too often. 🤷

[@JuanTodoli]

Have you got the tech info link of those interchangers above the compressors? (23:22) Never seen a thing like that 🤓

[@gendronhvac-r1269]

Those are heat exchangers for the oil. The oil from the compressor runs into those evaporator looking things. The head fan turns on and cools the oil. Then it runs back into the compressor. I don't have any specific like Tech bulletins on that that is just how I've observed it working. I hope that helps :)

[@JuanTodoli]

@@gendronhvac-r1269 Yep, I've observed that like you, just curious if there's specific info to se the efficiency numbers. Thanks!

[@gendronhvac-r1269]

@@JuanTodoli I've actually never really had a reason to dig that far into it so I'm not sure. If you happen to find anything let me know I would love to learn :) Sorry I can't be more help. If I come across information I'll let you know

[@JuanTodoli]

@@gendronhvac-r1269 Nah, I was spinning too fine 🤐 I've had a lot of free time these last couple of months taking care of a family member at home and I've taken the opportunity to watch practically all your videos and sew you up with questions. It mesmerizes me with how skillfully and in how many different situations you handle the manifold. I have learned a whole lot of things with you, thanks for filming (I know that it is often uncomfortable) 🙏

[@WillPlaysGames1993]

ive been watching a bunch if hvac videos (mostly hvacr videos hvacr survival and a few others) i feel like you were moving the sensor way to much for it to even pick anything than again i dont do repairs and your sensor maybe different then what they use

[@gendronhvac-r1269]

The kind of leak detector matters alot. We have another leak detector at our company call the Stratus. That leak detector you need to move like a snail. You can move any much quicker Pace with the Bacharach h10 Pro the one I use. Also there's a little bit of nuance when your customer wants a leak check in a certain period of time and how thorough you want to be and do you have like probable cause to spend an extra 3 hours leaked detecting. Anyway I hope that helps

[@OleRazzleDazzler]

that H10 is the holy grail of detectors. also, even with lesser detectors, doing refrigeration, although i dont do supermarkets. most walk ins with a leak, you will immediately get a hit a lot kf the times just walking through the door.
