I still consider our home walk-in cooler to be one of the best investments we have made in our own food security especially because we are able to keep this room cool in all four seasons. This allows us to store our vegetable garden produce here on a year-round basis.
We've used 3 different methods to regulate the temperature of our cold room. They all work, but they do come with different costs and benefits. This video will show you the basic installation requirements for each of these cooling methods.
Here are answers to some common questions we get about our cold room:
1. What temperature do you maintain in your cold room?
4ºC or 39ºF
2. Can I cool my room with automated vents in the winter and an air conditioner in the summer?
Yes. We've found that as soon as the outdoor temperature reaches -10ºC or lower, we can cool our room exclusively with the automated vents. If our vents were larger or we didn't open the cooler door as often, we wouldn't have to wait until the outdoor temperature was quite that cold.
3. Could I mount the air conditioner on an exterior wall of the cooler?
Yes. We live in a cold climate where we are typically adding heat to our home and when our basement was uninsulated and cool it made sense to dump the excess heat from our cooler into our basement. Now that our basement is very well insulated, the heat from the air conditioner can make the basement temperature uncomfortably warm in the heat of summer so I wouldn't advise mounting the air conditioner on an indoor wall in all situations.

I'm hoping to build a cold room this year and use the old method of having a warm air vent up high in the room to the outdoors and then another cold air intake which would drop low down to the floor. It will be non electric convection air movement. We have almost 2 foot thich old fieldstone walls, so I will have to use the window and just fit plywood and insulation to the open windows and seal that tight. I believe with a way to have a control gate valve of some sort on both the intake and exhaust, I can damper it each day as needed. Just looking to drop the temps from the normal 55-60 deg F tems down to 38-40 deg so at least my potatoes will not be sprouting in Dec or Jan.

Great detailed video. Where did you purchase those automated vents?

@AmericanEgyptianWays 5 месяцев назад

Wow pretty insightful , just one question , can we implement the heat pump idea for large cold storage rooms ? will it be economically efficient

@bouquetpizza9638 5 месяцев назад

Hey! Really cool ideas - particularly the SANCO2 unit. I'm building a walkin for a pizzeria and I was wondering the inner dimension of your cold room is? Also, do you find the SANCO2 struggles to maintain the 4 degrees at all? Thanks!

@medina3420 Год назад

Excellent video. Thank you for sharing Great ideas. was Thinking Heat exchanger. But In the Desert, Water is Precious. and Limited, "Water Collection" So may go with AC unit. Plenty of Sun.

@VegetableAcademy Год назад

With the heat pump method, the excess heat doesn't need to be discharged through a sprinkler. That was just the easiest option for us since we don't mind adding a little water to our grass or perennial beds once in a while. To conserve water, the hot water could be pumped through a closed outdoor loop in the ground until the temperature in the hot water tank dropped back down to acceptable levels. That pump could be automated the same way we automate the opening and closing of the valve to our heat dumping sprinkler.

@Fireheadman 9 месяцев назад

have been following you on the other video, finally got my cooler online with 2 inkbirds using an 24,500btu LG AC. Was able to get it down to 32-34 degrees, but it has been a struggle adjusting the low/high/set points on each ink bird itc-308 wifi units. curious if you have a write up and video that explains more on this?

@Phano300 3 месяца назад

I understand this is a year ago but I was wondering ... I read your article and in the article you mentioned using 2 fans to move air from the cooler to the living space in the summer when you needed more hot water (even though you have a tank less hot water). I see 2 fans moving air from outside to inside during Canadian Winter but I don't see the 2 fans from cooler to living space. I'm assuming you didn't setup those fans and I was just wondering maybe the tank less hot water is enough to supplement? Also energy wise does the tank less use less electricity than the air to water heat pump and that's why you decided to not add the 2 fans (from cooler to living space)? I'm seriously looking into this setup but I know most tank less do use lots of electricity but then again that's from city cold water to domestic hot water, your going from some what hot to domestic hot. Just wondering if you did the calculation and saw that heat pump would be less efficient over all. Thanks for your videos I am a new subscriber from a week ago and still learning. I love DIY! eh? lol :)

@nates2526 Год назад

I like the inline fans the best. I wonder if there is an easy way to program “when it is cooler outside than inside, turn on” to help keep a root cellar cooler throughout the summer.

@VegetableAcademy Год назад

Yes. You can accomplish this by adding an Inkbird controller A in front of the Inkbird controller B that turns on the fans. Take the temperature sensor from Inkbird controller A and put it outside so it can measure the outdoor temperature. Then set that controller to a desired temperature limit for turning on the fans. If you plug Inkbird controller B into the "heating" port of controller A, then controller A will give power to controller B whenever the temperature outside is below your set temperature, and then controller B which has it's temperature probe inside the cold room will only turn on the fans when the room is too warm AND the outdoor air is colder than your set temperature. This little modification can be helpful in the spring or fall, but this method won't help you much in the summer though, because air temperatures are usually too warm even in the night time to assist with cooling a cold storage room sufficiently.

@hugoboyce9648 Год назад

Really good video! Although for the windows air conditioner, there are really cheap refrigirator controllers available. That way no spoofing of sensors is required, and there is only one thermostat involved instead of 2. It does require modifying the A/C's electrical circuit though.

@chev572bb 8 месяцев назад

Any recommendations on a controller?

@tylerjbellows 7 месяцев назад

Any recommendations for size or cooler?

@Uturn977 Год назад

in the back room were ac unit pulls hot air what do u do to help with humidity that room has to be really hot

@VanillaAttila Год назад

Wonderful video. What temp is the water that you water the lawn with? No concern of burning plants? A radiant floor heating system could also be a great option for the excess hot water. Or perhaps a water filled radiator since that wouldn't require a massive flooring retrofit.

@VegetableAcademy Год назад

I also wondered if the hot water we were dumping would be bad for the plants, but by the time it travels through the hose, out the sprinkler, and through the air, it's lost most of its heat. Our aquastat opens the automatic valves to dump hot water whenever the bottom of the tank is 40ºC or higher. I like your idea of using radiant heating as another way to lower the tank temperature when needed. We are already planning to add radiant floor heating. Unfortunately, we need to dump most of the heat in summer and that's also a time when we wouldn't want to be circulating hot water through a radiant floor, so that can't be the only place we dump heat...maybe good for spring and fall seasons though.

@VanillaAttila Год назад

@@VegetableAcademy Yeah makes sense. What to do with excess heat in summer.. Thinking off the cuff,.. dump thermal energy into soil under a hothouse outside perhaps extending the growing season. ROI may not compute just to save a couple BTUs. Perhaps a hot tub holding tank outside that is guilt free from which overflow waters the plants and drain before winter. Does the unit produce cold water as well on demand? Either way your current set up is awesome. I'm going to implement a similar design when I install our cold room. How much does that unit cost? I couldn't see prices on their site.

@tsproductions5366 Год назад

A swimming pool would also be ideal to dump heat, especially in warmer climates where its more of a problem (and you get more use out of a swimming pool)

@VegetableAcademy Год назад

@@tsproductions5366 Agreed!

@farrongilbert4726 11 месяцев назад

What would you do if your air conditioner iced up because of humidity

@jhosk Год назад

On the thermostat on the ac unit, could you not use a potentiometer? In theory you could get rid of the other two temp controllers

@VegetableAcademy Год назад

I'm not sure what you are imagining, but if it can accomplish the same two tasks of turning the AC on when the room is too warm and also shutting the system down when the fins have any ice build up, then you're good.

@seandrake7534 Год назад

Do you have a video on how to build a cold room

@VegetableAcademy Год назад

Yes. That's in the Seed to Table course. You can learn more about that here: www.vegetableacademy.com/course

@dimitrov22 Год назад

Hi. I am new to your subscription. But it made an impression on me the first video I watched. Your entire foundation is built on the massive amount of energy to cool your storage warehouse. In my country, we call this a basement. As it is. I think your whole concept is wrong. You should have a basement with minimal effort. Otherwise, what's the use of the basement, since you paid more money for electricity, when it will be cheaper for you to get it from the store. In Bulgaria, when we build a house, we must dig a hole in the ground for a basement. It can be deep or shallow, but it must be mined. And you don't enter like through such a hole as you showed at the beginning. A normal door and stairs are normal. Even in tower buildings, we have a basement for every apartment. Our buildings is not too big. I like your initiative and will watch you regularly. Thank you. Sorry for my English.

@VegetableAcademy Год назад

Welcome here. I'm not sure I understood everything from your comment, but to clarify, we do access our basement with regular stairs. I didn't show these in the video. The short clip of a hole and ladder at the start of the video was reference to an older style of root cellar that used to be more common before houses in our area all had fully insulated basements. We use some electricity to keep this space cool. In the winter all we need is a little power to run the two ventilation fans, and in the summer, all of the heat we pull out of the cooler now goes into our home's hot water tank, so I don't feel like we are wasting electricity at all with this cold room setup.
