    This video was by far the best one I found for the AC set up. Mine is working great in the first 24 hrs with only a single Inkbird unit. I just had to adjust the location of the temperature prob vertically at the bottom of my AC’s fins and adjust the temperature a few times to dial everything in. It’s holding a steady 41 degree temp without freezing up. I’ll probably take it down one or two more degrees in the coming week. And I’m using a really old, dirty 5,000 BTU window AC. Update - one week in and absolutely love this system. The single Inkbird has worked great with the probe positioned vertically against the fins, centered and about 1/2' up from the bottom. I used a short piece of electric fence wire in a u shape inserted into the fins to hold it in place. So glad I came across this video while researching cooling options.

    • @VegetableAcademy
      @VegetableAcademy  3 роки тому +6

      Nice. I think you could accomplish almost the same level of control with one Inkbird. I am running ours right now with just the one probe in the fins and it's doing alright. One difference is that the air conditioner turns on a bit later, because the fins warm up a little more slowly than the air in the cooler. The air conditioner also seems to be cycling on and off more frequently because as soon as the fin temperature drops substantially to cool the air, the Inkbird cuts power to the lightbulb and turns of the air conditioner. I imagine this would be more of a problem in the hottest part of the year when the air conditioner needs to be running more often. This would mean that the fins would usually be at a lower temperature than the room air so the ideal temperature setting on the Inkbird might not be the room temperature you are shooting for. Setting the Inkbird might require some experimentation and adjustments throughout the season depending on your climate. Have fun fine tuning your setup. If you can't dial it in, you always know that you can add another Inkbird for the best precision.

We walled off a 10' x 12' area in the front of the trailer, With a stand up room ac we can keep the temps below 40f easily. We went with a single hose stand up ac because it does not draw in air from the outside as it is very dusty on playa.

    First off I want to thank you for the video. Here's what I came up with using your step by step instructions. My cooler 7Hx8Lx7W with 5" thick cooler panels. Built inside a 30' shipping container with a roof. I'm located in South Georgia. Go Georgia Southern Eagles! 1. I purchased a 10000 BTU Toshiba A/C and the exact materials listed in your video. Ok, I built this cooler to hold deer meat prior to processing. I want to keep the temperature between 36 & 38 dergrees. Here's my issue. I've only been able to keep the temperature between 40 & 45 degrees consistant for several days. My units keeps freezing up. I've set my controllers to 36, 37 & 38 degrees for room temp. and 29 - 34 degrees for fin temp. The lowest temp i've got in a 96 hour test run was 39 degrees and that was on Friday morning when the outside temp was 47 degrees. Now, I know that the outside temp. plays a roll. However, I have a co-worked that has the same setup I do and he has used a the same Coolbot for 11 years straight with no issues while maintaining a 36-38 degree temp. So, here's my assessmetnt. I think your method will work fine with the inkbirds for folks in the south who just want to keep veggies cool. From my experience, It's just to warm in the South for a meat cooler at the beginning of deer season. May work great when the temperatures in the south get cooler, say late November. So, I just wanted to let folks know about my experience in the deep south. Thanks

    This whole project took me about 20 minutes to complete. I can confirm that it works as intended.
    You don't need to be an HVAC tech or all that handy really as long as you have the right items.
    The 4W bulbs highest temperature was around 99 to 100 degrees Fahrenheit.
    One thing to keep in mind is the length of the temperature sensor on the air conditioner. The one on my AC barely has any wiggle room. I am going to have to set the bulb piece very close to the AC. With that in mind it was still reading 99 to 100.
    Thank you so much.

    As an hvac tech, I applaud you. If you are willing to learn a bit about the AC then you can get rid of the light bulb. If you run constant power to the compressor circuit but break it with the first temp controller, it will pass power to the compressor when temp rises. Leave the fan on all the time. Use the second temp controller as is to reduce freezing if needed.

I bet you could get by with a 2 watt resistor that you operate at 1 watt. power = v^2/R or R= V^2/P 5V*5V/1W = 25 ohms. 1 watt might not be enough, so might need to have a 10 or 15 ohm available too. also this would be nice because it would be low voltage.

    • @LivingGoodAlaska

      The air conditioner will have a continuous draw of nearly 2000 watts with a surge/start up draw of much higher. The continuous draw will suck a bunch of fuel and be hard on both machines and the start up surge will be likely to trip the overload on the generator constantly, causing the cooler to malfunction when you’re not around. The 2000 watt will probably run it in an emergency but for continuous use I would get a larger generator. I hope this helps🙂

      It may very well be cheaper to program an arduino to perform the same task with two temperature sensors. I don't have any arduino experience, but it still sounds like a fun project despite that. If you've got the skills to make that happen go for it, and please share how you made it work. The solution described here is a simple system anyone can assemble with off the shelf parts and no programming skills.

    • @VegetableAcademy

      That depends on the specific settings of your AC unit. On our current model, I can select a setting that will run the fan constantly to circulate the air even when no cooling is happening, or I can select an energy saving mode that shuts the fan off completely once the cooling cycle is done. I use the latter to conserve energy.

    • @VegetableAcademy
      @VegetableAcademy  Рік тому +1

      One of the settings is likely different from last year then. Our AC has an econo mode that shuts down everything when no cooling is called for, (ie. when the light turns off) but there are a few other modes that keep the fan running at all times with different fan speeds even when the compressor is not running. This is great for air circulation in the cooler and CoolBot recommends that the fan be left on, but it can use a lot more energy. I'd take a closer look at the manual for your AC to make sure I understood the settings correctly and maybe read through the CoolBot troubleshooting pages in their installation manual as well.

    I installed a resistor parallel to the AC room temperature probe. Costs less than $1. It makes the AC think its warmer than it is. This also allows the AC to make use of its inverter technology, saving power and giving a very stable temperature - somehting the Coolbot doesn't do either.

    I built a cooler like this based on this video. I now slaughter my own angus beef and age it in the cooler. One thing I found was that the amount of moisture coming off 4 beef quarters for the first 6 hours or so quickly frosts up the coils and condenser. I had to use a hair dryer about every half hour to defrost the first one. The 2nd one I left the cooler door open about a foot and put a big fan on high just inside the door to blow the moisture out of the cooler for about 2 hours, then left the fan on after closing the door. I put a dehumidifier in for the first 24 hours also. It only frosted up twice this way.

    Really great video though. only 3 issues i see with this set up as well as the coolbot. 1) im not sure what time of the year this box is being used, but there is no head pressure control for the colder months. you may or may not find you need this. 2) i see a potential for short cycling if for some reason youre bouncing around 1.5 c which could kill your compressor. 3) newer ac units use flammable refrigerants, such as R32. by doing all of these modifications youre changing the UE listing and assuming liability in the event there's a leak in refrigerant and it ignites.
    but again i really do like how you considered defrost. smarter guy than most.

    I've got a bunch of questions
    1. How big is that room?
    2. what Kind of AC do you use? or am I overthinking and is any kind of AC enough?
    3. How much per month does that cost in electricity?

    • @VegetableAcademy
      @VegetableAcademy  2 роки тому +2

      1. It's 5 feet wide, 9 feet long, and 6.5 feet high
      2. We have an 8000 BTU window air conditioner. Don't just use any AC. Use CollBot's AC guide to help you find a unit that is compatible with this method of control.
      3. I don't know exactly. I have done some heat loss calculations that showed the cooling cost for a room this size would be a little under $100 per year if the cooler temperature was always 4ºC and the temperature outside the walls was always 20ºC and the walls, ceiling, and floor were all insulated to R20. So there is a rough ballpark answer for you. I would like to put a meter on the AC circuit and track the power usage each month, but that's a project that hasn't been my top priority. This summer we switched to using an air source heat pump as the main cooling device. This is fantastic because all the energy removed from the cooler now goes into our hot water tank so any money spent on cooling just heats our water.

    Even though the LED is very low wattage I'd be inclined to find an alternative, similar to what Coolbot uses, a resistor of some kind. Perhaps even a traditional filament bulb. Heat is an enemy to semi conductor which is what a LED is. Covering it in any way will tend to shorten it's life & in the case of a larger bulb become a fire hazard. Seems to work for you though, so what do I know haha. Another thing with LED bulbs, most are fitted with a heatsink base. That might be a better place to tack the sensor rather than blocking the light itself by taping it over.

      @OP Remember we're talking about a refrigerator here, not massively high temps. Just needs to be hot enough to trigger the compressor to run. The passive cooling from being in a fridge should be more than enough to compensate for any "overheating" of the diode, if any. Hell, my pocket LED flashlight is so bright that the light itself can burn your skin or clothes if you put it right in front for just a few seconds. If you leave it on long enough on turbo, (a few minutes) the body of the light (which acts as a heat sink) will get hot enough to burn you if you hold the tip too long. It has active temperature regulation though, which drops the output of the LED precisely to protect it from too much heat. Still, it sustains high output for long periods of time, takes the high temps and the LED doesn't fail. That's a class leading, ultra high output LED chip on a tactical flashlight though, not a regular, low power bulb like the one he's using so I'm sure it'll be just fine and nowhere near a fire hazard.

    You can buy the modules themselves without the case and cords coming in, dual stage or single stage. You gotta provide the wires as such. Can get them in 110 -220 as well as in 12v that controls a relay for 110-220v. And depending on where you go you can get them dirt cheap. Run them to outlets and flush mount them, even outside the room so you don't have to enter the room to adjust things.
    You could also run an Arduino with a program and a couple relay boards, and set it precisely to do certain things.
    Turn on light when over x temp. Turn off the light when a different probe hits x temp, and even do a third or fourth to measure different parts of the room or fins.
    But I'd prefer to get in and pull out the electronics and wire it up to a PID or Arduino with pid, and a couple of proves to measure room temp, as well as make sure the fins aren't icing up. Arduino and the modules are dirt cheap to buy, even dirtier cheap to build.
    Cut out the entire light system, and just turn on and off the compressor based on temps you see.
    Many options here and the more techy you are, the cheaper it can be.

So we are looking $25-30? You can also set the arduino up to do other stuff, control humidity, lights, and send alerts when the temp is out of range.

We now use an air to water heat pump to pull the heat out of our cold room and use that energy to heat our home's hot water tank.
