WHY IS THERE MOLD IN THE WALK IN COOLER?

The customer was wondering why there was mold in the walk in cooler and why after he cleaned it off it just came back... The equipment was oversized and did not have long enough run times...

Never seen an intelligen system installed like that. Didnt even know it was a thing. Much bigger fan of the control board being outside of the box. Have had nothing but problems with Russell's smart evaporaters constantly going through boards and i feel the moisture from the box has something todo with it

[@zack9912000]

All they have to do is conformal coating placed in the board to waterproof it. They won't do it.

[@gsuberland]

PCB designer here. From what I saw on in the video, it looks like those boards have a thick conformal coating on them to prevent moisture from killing them, so I'd be surprised at it dying due to moisture. Maybe moisture buildup in the connectors, but that's pretty rare on vertically aligned boards. Should be fine here. Much more likely causes of failure are thermal cycling and bad power feeds.

[@Josh.SPublishingTeam2024I]

These are my favourite vidoes Freezer, Cooler and A/C installs, i learn so much from these videos 😊❤ thanks chris, I am only 12 but Its my dream to be a HVAC technician like you!

[@EnderMalcolm]

That is an adorably tiny evaporator. Edit: Coming back to the multi-system card. Another big selling point is that it allows very easy setup via internet-controlled monitoring systems in the future. Pop in an Ethernet cable and boom, it's hooked up to the monitoring system. Could even do a really simple alert-based system, text all the managers with the error code and current system temps. They will know immediately if there's an issue, rather than finding out 8 or so hours later when the ice cream is liquid.

[@Powertampa]

Yeah you could. You could also not do that and avoid giving the IT a headache in regards to network security. Only put things into a network if you absolutely need to. Less is more, don't need the beer getting warm over some idiot downloading malware to the network :)

[@Mr424242424242424242]

@@Powertampa That's why I prefer that IoT stuff run through its own dedicated gateway with no contact with normal network traffic. Preferably without the ability for anything outside to reach in, just it using a provider gateway to send emails or texts

[@Jadrie1]

​@@Powertampa Better idea is to, in advance, talk to the IT department and get their preference ahead of installation. A lot of teams are happy to get that sort of monitoring set up if the location would benefit from it, if they know well in advance: (NetSec might want it VLAN'd off to isolate its access, get a low voltage tech to run an ethernet drop to hardwire it, etc.,), it just requires communication with the other team ahead of time.

[@gsuberland]

@@Powertampa As long as you're only talking about outbound alerts and data reporting it's fine. Typically something like MQTT on the backend, feeding into a time series database and alerting system (e.g. PagerDuty). You wouldn't be giving this thing its own internet-facing IP address. My day job is doing security assessments on industrial control gear on stuff way higher price & risk than this, and lots of outbound telemetry is absolutely the norm these days. And the remote management stuff works the same way - the device sends outbound polls to a cloud service or does an outbound websocket connection (over TLS) for push messages, and it's all managed via that.

[@tschuuuls486]

The argument in favor for the wifi card would be Email notifications when there are problems, but the product is not yet spoiled. Also interesting that that California mandates more efficient fans and blades, but doesn't mandate hot gas defrost (which probably would be better for your customers as it should be more powerful).

[@Coffreek]

If people are worried about controllers inside coolers, they may not be aware of the IPX rating system. If you really want overkill, you can always install a heater and dessicant dryer inside the enclosure.

[@stephenbullock-yn3vh]

Excellent install 👍

[@dieselchevette]

Nice install video. You set an example of how to do it all properly. That Carel EEV is a great part, and it was sweet to see a tech using the magnet tool to turn it open/closed. That tool is indispensable to rule out the controls vs the valve when things act up. It was great seeing you at the show as well. I'd venture that your customer here I bet will see their power bill drop a bit, as well.

[@oscalerup1129]

That’s really cool. I did two walk-in replacements this summer. I got both to use a digital controlled evaporator, we used Russell, I liked them they also have huge capacitors to close the EEV upon a power failure. If I did it over though I also would still like a LLS. The Russell evaporators came stock with Sporlan EEVs which are very interesting and different looking to me vs what I typically see. As usual the customer is already on a budget and I always insulted the liquid line since in both applications the new line sets went through a very hot attic.

[@CopperCowboy333]

Amazing 🧜‍♂️ craftsmanship 👏.. as always 🎉

[@DelticEngine]

Hey Chris, this was an excellent, very informative and helpful video that managed to squeeze in key points about a lot of parts of the system and factors involved. Well done! Regarding the networking communication, I would go with wired ethernet always and disable any wireless communication. This makes it much less likely for there to be issues with WiFi glitches and interference as well as removing the possibility of wireless hacking which can be shocking simple to achieve sometimes. Ideally, the cooler ethernet would be on the business intranet rather than a more general network that includes internet access, although this can be mitigated if the business has intelligent network management and knows how to configure it. It would then be possible to allow, for example a specific device, and only that device, that you or your business has to remotely access the cooler network interface and see what is going on and maintain decent network security.

[@fshn76]

I was wondering where the DTC Valve was on the compressor since it was a 448a system. Then remembered it was for a cooler. Used to dislike 448a but I have became a fan here lately. Tube and fin CONDENSOR are so much easier to keep clean.

[@jasonjohnsonHVAC]

With EEV'S it is not uncommon for low superheat. Especially with VRF....I have seen superheat as low as 0.5°....with VRF, Chillers etc. This Heatcraft is pretty slick. The "front end" you were looking at on your tablet is pretty cool....its cool to see HMI's being more mainstream in equipment. In heavy commercial and industrial this has been a "thing" for decades now. It can and does give a vast amount of information.....as long as you understand what it is you are looking at. That was also a nice clean install yall did. Great video as always Chris HOPE YOU GET TIME AWAY FROM PODCASTS TO ENJOY AHR AS JUST AN HVAC GUY. 🤘🤘🤘🤘🤘🤘

Oh no, what happened to Sporlan? You took the Integrity, Quality and Tradition from us! ;-)

[@wtfux]

You sped through the box sizing and didn't make a humidity adjustment despite harping about cardboard weakening, were the defaults for a keg cooler setup sufficiently dry as is?

[@gordonrockafellow1211]

Walk in cooler humidity is more controlled by condenser evaporator match than system size. If you use factory match it is typically for 10 degree evaporator TD, which causes a fairly wet cooler. For a dry unit I will use a 15 or higher TD with electric defrost. I am in Florida where the humidity is high and a lot of places use walk in's in place of reach in's and the cooler door is almost open more than it is closed. If I use cooler factory unit sizing the cooler will not hold temperature with heavy traffic. The only problem with the high TD is having to use the electric defrost.

[@gregomyeggo4529]

Hi Chris, excellent video! I have a question. Where did you get that eev magnet? Who makes it? Thanks in advance!

[@sw6188]

[@davidmcclare443]

hi what was the reason that you installed a p trap on the refrigerant line?

[@ezchoicelab9904]

I think is a good idea to bing the CAT 6 cable together with EXV and Transducer in the same box. And let IT to take it from there, instead of letting them in your controller box.

[@thejnelson88]

In industrial refrigeration our Transducers come telling us not to mount upside down for that very reason. Oil messes with them so bad.

[@HVACRTECH-83]

Excuse my ignorance in this matter, I don't work on much refrigeration, but is that a common thing to have a fixed orifice downstream of the exv? What if it was a txv instead of a exv? I guess I don't understand why there's both a fixed orifice and expansion valve. I'm starting to work on more walk ins and freezers lately so trying to learn all I can. Great video btw as usual

Before replacing the equipment, have you considered putting a temperature data-logger in the box for a week or two, so that you can see the runtime on the current equipment and be able to more accurately calculate the capacity needed for the actual box and how its being operated?

[@ed6837]

Just wondering on a shut down if the EEV is closed and the solenoid is closed any issues with liquid trapped between the two? if the box warms up you would have tremendous pressure between the two valves.

[@Thermoelectric7]

I looked into this recently, pretty sure the solenoids will "leak" in the reverse direction, so any extra pressure will bleed back into the liquid line.

Chris Im confused for the ambient temperature for outside of the walk in is that for the condenser location because you put the ambient temperature at 105°F and then put the condenser on the roof of the building not the roof of the walk in like I expected the ambient temperature on the roof should it be alot highed than 105°F.
