Something I noticed is how much better the music overlay is on the braising scenes, it's no longer very loud. And hearing the sound of the torch in the background makes it feel more 'connected'. Plus if I'm typing a comment, normal line about 'love the content, great to pick up tips to use while doing similar things, made some home installs easier/neater'.

Also i noticed the pipes get pretty red hot when soldering, ive always been taught to avoid that “cheery red” on the copper because the silver in the solder can burn out at too high a temperature meaning a weaker joint and premature cracking/failure of the joint leading to leaks…🤷‍♂️

[@Eyetrauma]

As someone that’s been in the infosec space I can kinda empathize with the owners not wanting to bother with the web telemetry: imagine you’re the one that approved its installation only for an exploit to result in the cooling to be turned off, leaving you with a fridge full of ruined food and potentially a closure while you wait for stock all because you opted for a “nice to have” web server interface. That’s risk that’s hard to justify.

[@BeezyKing99]

HUH?! jeez dude, I thought I was watching someone else, not HVACR VIDEOS, with that new intro... Here's to a better year.

[@nuc2726]

Hi Mr. HVACR guy. I am a new technician 10 months into this career. I'm finally on my own and doing my own thing in the company I work for. Your videos are lifesavers for learning this trade. Often times I do what you say without asking for the why and it just works, so I don't really need the why. However, my company provides my nitrogen tanks, and they don't like me leaking nitrogen through the copper while brazing. They say it's a waste of time lugging it around, joining the hose to the copper, and a waste of nitrogen to purge it. We don't charge an actual hourly for our work; our hourly rate is baked in to a fixed price for each service. It's the same price whether it takes is 1 hour or 10 hours. I work in residential only. 5 ton is the maximum size system I have ever seen or worked in. We bring it to a vacuum for 25 minutes or until it reaches 500 microns, whichever takes longer, to remove contaminants. Is it crucial to use Nitrogen while brazing? Is there any unforeseen risk to doing it without the nitrogen? Do you know the reason, or have you always just done it that way because it's tradition?

[@spencertravis9338]

Look up the channel AC Service Tech LLC on KZbin. He has a video titled: “HVAC Brazing Basics With/Without Nitrogen”. He goes over the difference inside of the piping for both.

[@Ryan-rv7lv]

I highly recommend you find somewhere else to work, these are a bunch of straight up hacks youre working for! 25 minutes or 500 microns whichever takes longer lmfao so what if theres moisture or leaks?

[@nuc2726]

@@Ryan-rv7lv Run time is 15 minutes of initial vacuum. Close hoses and turn off vacuum for 10 minutes after. Note location of needle on the gauge (I'm the only one with an sman480 so I use the micron gauge built in) and if it changes in those 10 minutes (or doesn't stabilize the change-over-minutes value on it's micron count in my case since it tells me), check braze joints. If it doesn't change, let it run for until 500 microns, or 10 minutes, whichever is longer. So really, it takes 35 minutes to do a recovery or an initial evacuation. What is your technique?

[@ATSNorthernMI]

I work for a major grocery store chain and we get notifications on our company issued phones and the clock in app on our personal phones if a cooler, freezer, or any other piece of merchandising equipment is over temp. The system works as intended and if we have a major refrigeration issue, the management teams phones get notified right away so they can create a service order or emergency service order to get someone out right away. It's a nightmare having to move 10,000 products to coolers and freezers because of it but it saves a lot of money in the long run quickly getting to the root of the problem before product is ruined. Some companies could care less if product is damaged because they can just file an insurance claim but why put your people through that hassle but its what they pay us to do.

[@pattyPIMPIN]

They've done a revision of the fan motor bracket I believe, original one cracked often. Had an on call where every bracket was broken only one was salvageable and could not get the newer style locally. Got the old style brackets and fan guards to put in.

[@hgbugalou]

re: the remote cards, I wish I was closer to you. I do this kind of thing professionally and work in IT. There is slick solution somewhere here that would allow the best of both worlds and put you customer at ease. You could you put them behind an extremely tight firewall, or even better setup a VPN tunnel to your company with wireguard. Your company could even update the firmware over the VPN tunnel to put their mind even more at ease.

[@freezerguy]

You didn’t have one here but a general tip with IntelliGen and QRC controllers into make sure you either completely remove or if it’s adjustable set the anti-short cycle time delay to as near zero as possible. There is a timer built into the controller and they will compete with each other.

I'm thinking you should have someone who knows tech talk to them about the cards... and how they can be done securely.

Fascinating as always, and I appreciate how you explain what you do as you do it.

[@whatshappenedhere1784]

Its good that you give it plenty of heat to get your brazing rod to penetrate the joint, just be careful about overheating the joint because you can cause oxidation that can prevent the brazing rod from tinning the copper properly and getting a solid joint. You want the copper to be at a dim glowing red, not a bright glow

[@whatshappenedhere1784]

And that swage at 10:26 isn't ideal, but I'm just nitpicking we've all done these things before I just have the luxury of not having my work on the internet to be critiqued 😝

[@bladeoffuryx]

About the network card, I completely agree with the concern that is coming from leaving the network card exposed to the internet. Assuming the card is not programmed to connect to some proprietary server from the manufacturer and is only providing a local web-page, I think a good solution would be to restrict access to it by using a zero-config virtual private network (VPN) service, such as Zerotier, or Tailscale. If configured correctly, this will put the network card in an invite-only private network, where the client can easily add or revoke access to said card through a management website on a as-needed basis, without risking any exposure over the internet. A common trick usually is to connect the internat cable to a small ARM computer board, such as a raspberry pi (or its clones), connect said computer to the WiFi network via the zero-config VPN and that's easy and safe access.

For brazing like that, get yourself some metallized insulation board. Some actually has real metal (or you can put a piece on it). That'll both spread the heat splash, and keep the stuff behind the pipe cool.

[@AIM54A]

A small roll of fiberglass cloth works great as a heat shield when you have to torch next to something that can melt.

[@alexanderkupke920]

A word of caution regarding the amount of solder you use. It may not only an issue about using more solder costing you (which I guess is pennies at most), what may happen is under some conditions that an excess amount of solder wicks through the joint and may either bead up on the inside, possibly causing turbulence in the pipe, or may cause beads of solder to float through the pipes as well. For the latter the dryer filter may take care of, but I am not entirely sure where in the system you place it. The turbulence can cause different issues, from making noise to actually seriously impacting the amount of flow you get through the pipe and possible cavitation issues.

[@nebraskaman8247]

There’s really no sense in using that much solder. I prob could have borderline done that entire install with a single stick. Also, no need to glow the copper that bright of red. Just pull the flame back some. Although, everyone does it differently.

[@phillip5397]

@@nebraskaman8247 like he said “it’s my company I can do what I want.”

[@thedane6483]

i dont agree. Using enough solder and heat is GOOD: It makes more secure solderings and if in difficult spot it flows better. Yes if he fills the pipe with solder you are right about turbulense, but that isnt the case... Good Soldering job

[@alexanderkupke920]

@@nebraskaman8247 Well, I might add, that "glowing" the copper may be relevant. Although I think especially with copper you have to be carfull, as it can be damaging to the copper (although I dont see this being anywhere close. When I learned soldering decades ago, besides electronic soldering which was what I did mainly, for different reasons I learned quite some metalworking and also soldering with that. First of all, in German we differenciated between "Weichlöten" which would translate into soft soldering, and "Hartlöten" which translates into hard soldering, but actually would be referred to as brazing or silver soldering (depending on the solder type) by most english speaking people. "soft soldering" would be the kind of soldering comparable to electronics, you might use for plumbing for example or in some roofing applications with tin or lead covers. And for brazing we were taught to actually to get the material "chery red" and the material was then supposed to have enough heat to melt the solder, so we were supposed to not even hold our brazing rod or silver solder into the flame. (At least that was what we were told, I think the point was that the material should be hot enough and not just melting the solder, as otherwise the material wouldn´t take any solder). But then we never used that with straight copper or even any pipe materials, so it sure is not completely comparable. I guess there are several schools of thaught or teaching methods for this, as you said, everyone does it differently. For all I think the point is what Chris pointed out several times, get the material hot enough so the solder will flow in between properly and not just bead up on the surface.

[@pedrogrady]

Those should be fans that suck cold evap air through the attached ducts, which enter a wall cavity where the air cools the beer lines----between the cooler and the beer taps (dispensing tower). This method is known as "short draw" (beer lines under 25 ft.). The other method for cooling longer beer lines is the installation of a glycol chiller, AKA Power Pack and is known as "long draw," where the beer lines run perhaps between floors and other uncooled areas and are bundled together with cooling, glycol lines, which constantly circulate between the glycol chiller and the dispensing tower. 🍺
