THE WALK IN COOLER IS TOO WARM

[@ViciousSadistic]

I Fired someone once for not closing the walk in door. Had to warn the guy like 50 times over a month. If you cant remember to close a door. How can I trust you to remember how to do your job completely and correctly? Kept trying to say it wasn't him. Ahem, that camera right there actually works.

[@jaysonhines1]

Well said.

[@Josb_Bluebird2143]

I worked for a grocery store that had the plastic curtains and door alarms on the walkin coolers and freezers. They would fire anyone who pulled or cut the curtains off. Worked with a guy that had been there for many years and he used to be the deli/ bakery manager when the store first opened. He got tired of the curtains smacking him going in and out when they were busy. One day he decided to cut them off a little taller than he was. They threatened to fire whoever did it, but all of the employees were roughly the same height so they couldn't prove who did it and he wouldn't tell them either.

Great video.The restaurants with open freezer doors just need a super powerful dehumidifier to keep the air too dry to condense on the coils.

[@throttlebottle5906]

oversize the refrigeration by about 35 times, get rid of the vent hoods, exhaust fans and all interior doors. 🤣🤣 there you go, the whole building is one giant inefficient dehumidifier. 🥳🤡

[@wackyworldofwindios3476]

Good morning you staying warm down south.

[@rockercover]

The icing of the evap.’s caused a memory recall in me of two walk in cooler sites, for two different drive through dairy product stores I worked at. One store had two fans in the rear of the coil, near one wall, pushing, (not pulling the air, which would become iced over often. The other store had the single fan, much larger, (more air flow volume), on the bottom of the coils, fan side facing the floor of the box. Rarely saw the single fan units iced / frozen over. The store with the single fans also had routine maintenance by the same company. So may have been a combination of different factors. So interesting.

[@prodigy3xtc389]

You can put a sign that says please close door behind you and they would Still fail to close the door. Laziness is a choice not a habit

[@SeanMackBuffaloStyle]

I have found an unusual problem on this exact heatcraft cooler evaporator coil. Fill the entire evaporator pan full of water, to simulate worst case defrosted coil. With the fans on full speed, creates a static pressure air curtain that actually holds the same water in the drain pan for many hours. I tested this with no drain line connected to the pan fitting. when the fans go to low speed, it starts to drain much better. I think heatcraft is unaware, bc in drain mode, the fans stay on full speed not draining the water out of the pan. this is becomes problematic on a lower superheat setting. the water in the pan freezes to the bottom of the evaporator coil. I found this problem in many applications at 35 to 40 box temp design...i.e...keg cooler, vegetable cooler, meat cooler, blast cooler.....the air out of the shroud starting spitting water out with a fully defrosted coil. Replicate this out if you get a chance.

[@jaysonhines1]

Nice observations dude

[@HVACRVIDEOS]

try putting a p trap on the drain line with an air vent, you likely have a vacuum issue in the walk in preventing the drain from draining, I will discuss this live on KZbin this evening 2/27/23 @ 5:PM (pacific) come over and check it out kzbin.infoy_KaNe4Bivk?feature=share

[@SovereignTroll]

All HVAC in Eastern Ohio and Western PA. Please don't have any bare skin on roofs and treat used filters carefully. They concentrate all the toxics and you must have proper gloves. Chemicals can absorb directly through skin, place them in plastic bags to prevent contamination, especially of your van. Don't make dust. I am a ret. Chemist that turned to the trades. I worked in a moon suit often dealing with vinyl chloride, chlorine, Ethylene oxide, anhydrous ammonia and more. Soap and water often.

[@ocko8011]

New homes, still in framing need to have every surface purged of dust and debris before finishing starts. Entombed contaminants in wall, floors and ceilings are costly to remove and pose significant long term health risks. Auto intake and cabin air filters should be changed as soon as possible in these areas as well.

[@Freonleon]

Or just suck it up and work, your gonna die anyway.

[@SovereignTroll]

@@ocko8011 Gosh, I didn't consider that. I now, because of you, now consider roofing. Asphalt shingles will absorb hydrocarbon toxins and the leaching out over time, disposal will become an issue. Roofers will now be constantly exposed for several years in those areas but metal roofs are probably immune after several rains. I found online vinyl chloride and phosgene react with water to acids that will dissipate over years. An occupational risk...

[@stevencossaboon3237]

Nice job Chris.

[@mattwoodbridge7924]

Awesome

[@Brisket9392]

Curtains don't work. They get cut or slung over whatever is outside the door. I think a timed door alarm that was not easily bypassed that sounded a progressively louder and louder siren would work. Something that would be painful or severely annoying to hear would change their behavior. Asking/Explaining why or putting signs up I find to not be all that effective.

[@Eddy63]

Good vid and I just ordered a black hat large/x large from your site ... Thx Bud ...

[@johnriff85]

With those Bohn Heatcraft smart boards you need to always ensure there's not a master controller outside of the box. That will revert your changes at the evaporator coil. Also you always need to double check the accuracy of all of your probes. The suction temp transducers on those constantly break.

[@HVACRVIDEOS]

If it was a beacon system yes you need to look for the master controller, but this Is a qrc system (quick response controller) there is no controller besides the main board

[@johnriff85]

@@HVACRVIDEOS very good to know. I've primarily dealt with the Beacon II systems. I despise them, but they've become easier to service now that I've seen so many issues with them. I'd personally prefer to see evaps on a walk in (that's not a rack system) controlled by either a K2, or a Dixell. I've seen so many beacon II coils iced up due to the transducer or thermistors being off which seems to happen a lot more frequently than it should.

[@coryevangelista310]

If it’s a cooler I almost always have to raise the defrost termination temp because I’m in a high humidity area

[@jasonyeager9102]

Chris, have you gotten any Heatcraft equipment that has been wired incorrectly from the factory? We received two on one gas station job where whomever wired it at the factory had one leg of a heater landed on the fan terminal for walk in freezers so as soon as the fans kicked on one defrost timer blew up and the other one tripped the breaker. Granted, best practices would have prevented this if we would have double checked but lesson learned to double check the wiring from the factory.

[@HVACRVIDEOS]

No I can't say I remember any of it being wired incorrectly

[@jasonyeager9102]

@@HVACRVIDEOS hmmm…I wonder if it’s just the units they ship to Iowa…have had 4 in the last year wired wrong from factory (base units, not Intelligen).

[@peti14045]

Hi Chris! Just a question when dealing a situation like this, it is not better to get rid of the ice with an electrical heat gun? I mean you said you don't want to submerge the evap fan motor. And then you can remove the motor. Would be a time and energy wasting procedure?

[@wtfux]

Why is the ice block not over the right third of the coil though? Also, do you try to yank off the ice on the underside of the drain pan first, or do you let it naturally fall off as it gets heated by the hot water you are spraying?

[@MyHiei]

I just started trade school for HVACR. What are some tips and tricks you could provide for me?

[@jfwfreo]

The problem for these businesses is that if they yell at staff for leaving the door open (and punish staff who do) the staff won't want to work there anymore.

[@danpresson]

To back that the managers don't in force it good video

[@glennschlorf1285]

Those coils need to stop the fans to defrost.... it would make them more efficient in the defrost mode not pulling the cold air across that coil. Seems like an error in engineering

[@anthonyleduc8461]

So why was it icing up to begin with?

[@CrimFerret]

I'm sure they'd like to enforce rules about closing the walk-in doors, but they know if they tried that, the cooks would quit and have jobs elsewhere the same day. It's literally cheaper to call you then to have to go through hiring a new person who's just going to do the same thing and prop the door open for their own convenience.

[@DrGreenGiant]

This seems so unbelievably backwards to me. If staff would leave if you enforce a reasonable and simple rule then they clearly don't have much incentive to work for that place, so I don't blame them for leaving. Incentives are really powerful.

[@drewc7479]

Hey guys I'm replacing a walk in cooler at work and the old unit had a suction trap at the evap , the condenser is just on top of the box with like 10 ft of piping. I don't really know why I'd need a suction trap on the new one , but if anyone has any input I'd appreciate it 👍

[@HVACRVIDEOS]

You can probabaly get away without it but I personally would install one, just to be safe

[@kyletegler5503]

I've been told every 8 feet you need a trap.

[@drewc7479]

@Kyle Tegler I would get if the evap is a lot higher than the compressor you wouldnt want a flooded start from liquid pouring down the suction. I added one anyway I'm new to refrig. Difficult when manuals are basically non existent for this keeprite evap and condenser and you gotta just go off research

[@mrod72785]

Why does leaving the door open cause the evaporator to freeze?

It lets warm moist air into the box, which then freezes on the coil. It also makes the evaporator run continuously to keep the box cool
