WHY CAN'T I PROP THE DOOR OPEN??

[@N0Sbackfire]

A door alarm that goes off on a timer would be excellent for that location, since I've seen you place one at a different location for the same reason You have every right to be frustrated about going out to that location because your customer is completely oblivious and apparently likes spending money on overtime service calls, when they could simply follow your advice and let their employees know as well. We're all human and you're doing a great job.

[@graywolf2694]

They just disabled the alarm

[@TheAussieRepairGuy]

I've worked in various industrial areas in a repair capacity - alarms get disabled and people go to ridiculous lengths to override safety equipment, alarms, and guards, rather than do a job safely and correctly. Sometimes you have to bend the application around the workers. Such as air curtains or plastic strip curtains or something. Though I frequently hear of staff replacement being the final solution.

[@fortfun46835]

I'd connect it to the compressor so you just stop trying to cool down after 10 to 20 minutes of the door being open.

[@Kwaq84]

@@fortfun46835 That's one evil idea ;) I like it! No alarms, buzzer etc. You left the door open, it naturally warmed up. Asking why? You leave your fridge open in your home? Might be pain in the ass for other guy to figure out why compressor won't start, though ;)

Venting your frustration about your work is healthy and shows you actually care about the work you do and as long as you are courteous to the customer bottling up that kind of emotion just leads to randomly lashing out at a later date.

ya know what I've been trying to bring back in fashion, Air Curtains, they can leave the door open all they want and the air curtains keep the hot out and cold in. Or for less money, IDK about America but here butchers always had a thick plastic curtain cut into strips hanging down, which helps a lot

[@FerralVideo]

I see them here in FL, along with warnings to not leave doors open, and HVAC alarm indicators that go off if the doors are left open. In fairness, this is FL, where there's so much humidity that you'd probably turn the evaporator into a giant ice cube in five minutes of opening the door ...

[@Phred_Phlintstoner]

I'm in Wisconsin and we use the plastic curtains for our finished product freezer at work. Keeps the freezer from getting ice on the ceiling and dripping all over everything during defrosting.

[@n.gineer8102]

Id tell them go for the plastic. Less work than air curtains. Most employees are ok with plastic.

[@dgk42]

I know a guy who installs air curtains in medical facilities. It deals with temp as well as creating a barrier to unwanted particles.

[@altus1226]

Another way, though I've only seen it once- is to have two plastic half-doors on a hinge, much like the front gate door thing in saloons in old westerns.

[@analogmoz]

Chris, I've advised restaurants to use an industrial circulator fan to blow steam off hot foods for a minute or two before the speed racks are stored in the WIC. It seems to help quite a bit. Failing that, you may need to add plastic sheeting inside the doorway. Thanks for the video.

[@rustblade5021]

it's also totally against health code to put hot food inside a fridge. it has to be cooled first.

[@Phred_Phlintstoner]

@@rustblade5021 not if it's being flash frozen. If so you use a cooler to drop the initial heat before putting in the freezer. But that's more industrial use not restaurant/commercial use.

@@Phred_Phlintstoner yes, you can use a blast chiller but they are quite expensive

[@Phred_Phlintstoner]

@@DanO181919 I'd love one of those. I have worked in the same food production plant for 15 years now. We just have a cooler with an outside air fan to take it from the over 165°F just out of oven temperature to the just over 130°F point where time becomes critical. It then goes into a freezer to come down in temp the rest of the way. We call them a blast cooler and blast freezer, but other than the outside air fan (which was only put in the side of the cooler 7 or 8 years ago) they are really just walk in coolers/freezers. We are a pretty small company.

your temp controller air sensor is on the discharger side of the evaporator!! move it to the back of the coil and your box wont have large swings in temp and will hold a more accurate temp. love the video's awesome work!

Yes, I do domestic and yes some people do, when they cook dinner they would have it open for 15 minutes while getting crap in and out. All the eggs condensate. The cooking always tastes terrible, and they start eating out all the time. I've even seen shows on the idiot box where they leave the fridge open when making dinner. This week, 2 girls were sitting in the doorway of their house and telling me the ac is leaking a tiny bit, yep it supposed to do that with the door open, charged 180 bucks, and they didn't shut the door, they just accepted it would leak when the door is open all day.

[@nottheinternet6276]

I've done a lot of work in IT & a frequent call I've had is with document scanners making lines on the scans. I'd explain to the customer that they need to open the lid & clean the glass on the scanner. They would state they already did that & they wanted me to come out to fix it. I'd go out & after verifying the issue I would clean the glass & then try another scan which almost always was perfect after a little window cleaner & a paper towel. I know your frustration, especially if they try to argue about the bill! As long as I'm getting paid I try to just focus on the dollar signs at that point & be happy I made easy money. If they're going to argue about the bill when I've done everything I can to help them before going onsite then they can be someone else's customer in the future because at that point for me it isn't worth the frustration.

I get what you're saying about being frustrated because I know how it is. I was a auto/jet engine tech for over 40 years. I dealt with the public like you do and I got frustrated like you do. For years, I held back my frustration but there came a time when enough was enough. The public does not see the big picture nor do they care. So, I decided to weed out those people who would not head my warnings about their auto's/ jets. I told some of my customers that they need not darken my door way again and so I never saw them again. Understand, I had more work than I could do anyway so a few less people didn't bother me. In fact, I felt much better when those people were gone and I could fully concentrate on the people who actually cared. You may or may not find your point of no return but if you do you will find the work you do goes more smoothly than you could have ever imagined. Good luck to you in the future and never take that frustration home with you, that is a big mistake, trust me. Sorry for all the waffling but it had to be said.

Good idea but bringing in hot food is a bad idea. He should charge them to oversize it again since it was not intended to be used to put hot food in to begin with. I am sure anyone with a half of a brain has been taught you don't put hot food in a fridge. I used to be the corporate service tech for 21 of the 29 Ryan's Family Steakhouses in FL and we had some stores where the cooks kept the Blodgett ovens on 500 degrees till closing time then hose them out with water and had lot of maintenance issues. We had curtains on some walk-ins because of doors left open on higher volume stores. What helped in my case was to implement PM maintenance training for all employees and if not done, this would directly impact managers bonuses.

[@SchwaAlien]

In this situation I wonder if a slightly less cold evaporator near the area they bring the hot food to could be set up just to rapidly dehumidify the air before it reaches the colder coils, seems like the moisture from the hot food may be more of a problem than the heat from the food.

I like to use a higher differential, like leave the setpoint at 34-35 and set the dif to 5-6 for more off cycle defrost.

Workers generally don't care about the equipment, they are focused just on their food and getting it out the door. The really fucked up aspect of this, is that most facilities don't run 24 7. So, they actually have reasons to be in and out of the doors. Places with a 24 7 operation at least have some flexibility in operation. Jesus!

where do you get the water hose to clean those condensers its not in the links

[@dashcamandy2242]

It's just your standard "watering wand" available at home improvement and garden stores, as well as major stores like Walmart and Target. The price/quality varies from manufacturer to manufacturer, but it's not a specialized tool.
