I really appreciate how you go play with an older rack system and then (just guessing) go mess with a residential split lol. That’s a wide breadth of skills and kudos to you to make it happen! If you aren’t already you’re gonna be reefer man all the time lol
Great work as always sir . The problem in our trade is that we need so many tools , it's hard to find a balance . Getting older we try to use a smaller lighter tool bag but then you keep going back and forth to the van ... And in my field , the van is often parked far away from the equipment so that's a real pain !
Getting it done....the name of the game in the summer. I had to deal with an issue recently on a 80 ton RTU.....fix3d the issues and found the oil sight glass was empty. Since the building was 95°+ i pumped in some oil to keep the compressors from grenading themselves.....now that its had the weekend to process the building temp down....im gonna go back and look for any oil leaks. With any luck the high discharge pressure will bring the oil back if it was logged in the evap. If i see oil stains...then i know i have a leak and can proceed with a leak search and repair.....sometimes in this business its about getting it up and going over all other issues. Doesn't mean we dont care, didn't notate it....i appreciate your logical outlook on situations and real world approach to situations
Yeah they've been telling us that for years. Theoretically any blend whether it's just two like 410A or whatever. The different refrigerant components would leak at different rates but also the thought process has been, did it leak in a liquid form or did it leak in a vapor form. I've only had a few times where 410A actually fractionated or it could have been just not condensables in the system.
Thanks for doing these videos! I always learn something. I have worked on everything from industrial ammonia systems to low pressure chillers over the span of more than 30 years, but never a rack system. Always enjoy watching.
I guess it’s always an emergency when the beer coolers are down! But it’s cool that I was able to get the first comment. Keep up the awesome work brother!!
Hey hello sir!! Been awhile I seen a post from you! Probably my fault. But Glad to see you still doing what you do! Also seen some posts from The Great Bearded one!👍🏻👍🏻🇺🇸
Good video Rick. I’m glad to see I’m not the only one still working on those old Hussman condensing units. We still have a few down here in Alabama. Keep the content coming
Two things… I love the old ass analog manifold 🤘 Like a true OG… Second, nothing beats that Stratus, my dude 🤙 I’m not in the field anymore, but I don’t think I can ever bring myself to sell mine 😬 Great videos, man. You’re legit
🤫I have digital too🤣. I use the analogs when I have to adjust pressure switches. But there are times when I use the analog gauges and I'm like "man it's been awhile since I've used these and I kind of miss it. "
@@HVACRSurvival Hey, I’m not knockin’ the digital sets! They’re amazing! But you know a true tech when you see those beat up analog manifolds come out… Honestly, I appreciate the idea that all your associated temps are right there on the digi’s and you don’t have to do the math, but I have high respect for those that use analog who actually know how to use them. I’ve never owned a digi set, and I’m kiiiinda proud of myself for that 🤣 Or maybe I just like to make things harder on myself and I’m a big moron 🤷🏼♂️
Making it look too easy! I appreciate the aside for the tool bag. I switched to TP-LC from the MB3 recently and I don't really like it. I wish they would just make a V-swap for the MB3. I can't find anything else that even comes close 💔
Those black colored cushion clamps are not even rated for discharge line temps. The plastic will melt and cause the clamp bolt to loosen due to excessive vibration.
The same used to be said about all the other blends. I've never had any fractionation problems with 404 but unfortunately 407 f is three blends. I lost a good majority of it, I would guess 80% or more was all new. What I didn't talk about was I didn't have a lot of refrigerant at the store so I couldn't afford to lose what I had and it was over the weekend.
Not an expert, longtime fan. Speaking of which, is the rack room ventilated well? I saw one outside air damper partially open, another closed. Do the exhaust fans and supply dampers generally work in these spaces? Where I work, even after multi-million dollar renovations, they miss the basics like that.
I never finished setting up my patreon since no one donated to it, my main thing I have is PayPal. You don't have to but if you want to here you go. Thanks for watching! www.paypal.me/RickDirmeyer
Spoken like a true veteran of the field. If you're gonna give me crap about not pulling down to 500 microns you obviously don't work on equipment this old
That's just real life, according to the same people that preach 500 microns for everything also tells you that you can't get the moisture out of Poe oil. And a filter dryer is the only way to remove the moisture.
Rick I always look forward to your videos! Please keep them coming! You’re so knowledgeable and the best at explaining everything!
🙏🤜🤛👍👍. Thank you!

I like refrigeration best over heating, I always did even before getting into refrigeration. Thanks for the support!

The struggle is real 😁
Warm beer ?, Run Rick, Run.
Love seeing these bigger commercial units being worked on, keep it up :D
Thanks, will do!
It says so much about your abilities to go into such a complex system and repair it so quickly
Love your videos the grocery refrigeration videos are very interesting I never knew how complex they were
Thank you for your feedback! 🤜🤛🙏🙏

Thanks Jason, I'm surprised I don't hear more crap from people but I try to explain why I do things the way I did if it's questionable.
Great job Rick, you work with passion and make sure the job is done right. Keep going strong 💪
Thanks brother 🙏👍👍
407c is zeotropic so if you lose some of the charge you have replace the whole charge. Correct me if im wrong but this is what i’ve been taught
Yeah they've been telling us that for years. Theoretically any blend whether it's just two like 410A or whatever. The different refrigerant components would leak at different rates but also the thought process has been, did it leak in a liquid form or did it leak in a vapor form.

Awesome video old mom & pop grocery store.Signal system.
Thank you!

Thanks for taking the time to watch them. My last video was more detailed on rack controls
I guess it’s always an emergency when the beer coolers are down! But it’s cool that I was able to get the first comment. Keep up the awesome work brother!!
Thanks for being a subscriber! 🤜🤛👍👍...#1
Lol. If anyone gives you grief about vacs on racks has never worked on a rack. Nice job.
Hey hello sir!! Been awhile I seen a post from you! Probably my fault. But Glad to see you still doing what you do! Also seen some posts from The Great Bearded one!👍🏻👍🏻🇺🇸
You have to turn on notifications. I post every week
Great job Rick.

Thanks brother!
Great work in a tough space. Thanks for the video.
Made me thirsty looking at all that beer... 😁

Good catch rick on this one
always a good day when u post
Thanks man!
Good to see another awesome video

Thanks man! I understand the tool bag battle😁👍👍
You will find as your Rack system experience continues that those clamps will loosen oven time, especially on the discharge.
Those black colored cushion clamps are not even rated for discharge line temps. The plastic will melt and cause the clamp bolt to loosen due to excessive vibration.
I’m surprised they don’t make some red hi temp ones
@Jonny what ones do you use then?
@@HVACRSurvival www.hydra-zorb.com/mm5/docs/HZ_High_Temp_Product_Guide.pdf
@@HVACRSurvival there is also a blue insert that is rated for higher temps.
we demand sub 500 microns!!!! 🤣🤣🤣 10 years later, it's almost there
😂👍👍
Great Video. Thank you for sharing.
Thanks for watching!
Thank u, I learn a lot from videos
Thanks Tim! I love hearing they are beneficial to people. Awesome!
How much of that original charge was left because its not R407F anymore.
The same used to be said about all the other blends. I've never had any fractionation problems with 404 but unfortunately 407 f is three blends. I lost a good majority of it, I would guess 80% or more was all new. What I didn't talk about was I didn't have a lot of refrigerant at the store so I couldn't afford to lose what I had and it was over the weekend.
There’s a considerable temperature glide with any of the 407’s and negligible with R404A. Of all the gasses to be short of….thats a bugger.
Nice job man. Very efficient. You sound like me in my head 😂
And I think I sometimes do it out loud when I'm not recording., 🤔🤫🤣🤣
Great video as aways, and always professional. Jerp ip the grest work.
🙏👍👍🤜🤛
Thanks for a great video 👍👍
Very well done video! Thank you for putting these together. I always learn something!
Awesome! Thank you!
New camera nice.

They are normally controlled by temperature. Usually they work, the room will overheat if not and that would put more load on the compressors.
Thanks for the reply! Appreciate you and your channel so so much.
Unlike a couple other channels I like my viewers enough to reply.
500 microns on a rack lol, that'll be the day
Rick can you link your patreon so I can tip you for these quality videos?
I never finished setting up my patreon since no one donated to it, my main thing I have is PayPal. You don't have to but if you want to here you go. Thanks for watching! www.paypal.me/RickDirmeyer
@@HVACRSurvival sent you a tip Rick! Start posting that link on all your videos! Knowledge isn’t free! Haha
I used to, thanks again!🙏🙏🤜🤛👍👍
Bud light isn't real beer, so there no loss.
😁😂
👍👍👍
wow all is very dirty, you need a better maintenance of the refrigeration system😲
They don't have us do any preventive maintenance only repair.
did you get free beer? :D
🍺🤫
504 thumbs up
🇺🇸👍💪❄️🙏

@HVACRSurvival if that were true about POE oil it wouldn't be used. Filter driers are important as more of a back up because there's no perfect vacuum
Thx
