Tips and Ideas for a Walk-In Cooler

Belo

5 year old buck +
We are currently building our dream home on 40 acres in western ny which is on a semi-functioning peach and apple orchard that will over time turn into a road side stand at its best. The land was owned by my wife's late grandfather and there are 2 outbuildings, 1 is going to be sold with the existing house and has a walk-in, the other is pole barn with dirt floors, structurally sound but in need of a little work to make it what I want. It will have water and electric that is now ours.

On the back of the pole barn is what I would call a lean too, but is basically a sloping roof with an open front that's been used to store fruit picking ladder, apple crates and a few pto attachments. We currently have half of it used for firewood.

I have the brilliant idea to turn part of this into a walk-in that will mostly be used to preserve apples and peaches, but can also be used to hang deer for an early bow kill. Generally in NY we don't worry about hanging temps, but the sloping roof is 8' at its lowest so why not put a hanger in there?

Anyhow, I will include pics later, but it's semi framed with the roof and 1 side. I'll need to build a floor, some additional framing on the front and side, frame for a door and then cutout a slot for an a/c unit, wire some electrical for a light, hoist, the a/c and a coolbot.

I'm handy, but carpentry isn't my specialty. I don't need pretty, just functional and in the beginning stages of planning this all out and thought I'd make a post here for anyone who has tips or wisdom for me. I think initially I was hoping to stay around $2k not including the electrical work, with my biggest cost being the coolbot and window unit, but was caught off guard a little with how expensive insulating board goes for. I see recommendations for r25, but r20 would meet my needs and saving more on only going r10 for the floor. I see kits for spray foam for sale but haven't done enough research to know if that's more cost effective. With some basic rough lumber included I'm now around $3.5k and again that's without some misc stuff, so likely closer to $4k.

Anyhow, any advice, tips or tricks is more than welcome. Thanks in advance!
 
Good question, I think they sell them pre-made ?

Hopefully someone on here gives you some advice …
 
What temp are you looking to get in there.

The 1st thing an A/C evaporator does is condense moisture to water. Then once you hit 100% humidity, the temperature starts reducing more.

When a typical A/C approaches the freezing point, it ices up. Also, some A/C's start to have problems with compressor at 40ish temp degrees outside. Couple that with poor evaporator performance, you might damage the compressor.

I forgot which refrigerant is better for the walk in cooler via A/C. But it is a concern. Might want to look at which A/C unit someone has had good luck with and stick with that.

You could do this for round $1000 if you go smaller sized. Something to fit 2 deer in.

A garage ok fridge with the door removed and a circulating fan added might be a bit better.

I am thinking of buying the biggest vertical freezer, putting a few hook on the top and hanging quarters. uartering, putting in the basement fridge with plenty of absorbent for it to sit on seems to be doing ok so far.

Kinda like double lung, because they pump most of the blood out.

I live in the hudson valley NY. Even rifle gets too warm. Even muzzleloader has been too warm some years.

R-13 fiberglass with foamboard and the cheap bathroom wall stuff is an cheap n easy way to go. Look on craigslist / facebook for foamboard. Someone trucks it in for 1/2 price. Isocyanate used boards are cheap, but hold moisture. IF it stays dry inside and sealed from the inside via good boards n caulk, you'd be ok. Seem folks use just 2 inch foamboard R-11 or so and be ok.

Using it for apples for months at a time, extra insulation will save $$$$.

I can apple slices pie filling and make applesauce and freeze. Save a few good desert apples. Mostly macoun.
 
I was recently surfing on Facebook Marketplace and saw several walk in coolers for sale in various conditions. That's the direction I would look. I think you could buy something that would be far easier and cheaper (and better?) than you might build. (at least around my part of the country)

Example:

 
A proper setup on a budget would be an embarco 1/2hp compressor chiller combo and a 4000-6000 single fan evaporator. About $1000 for both. Copper lnes, reciever dryer maybe, sweat in service valves if needed, thermostat. A few r-134a cans, service gauge set, and a vacuum pump to put in. Did my heat pumps myself.

Heat pump condensor unit might be retrofitted to work too possibility.

The redneck 2-4 deer setup with an A/C has been done many times before.

FYI many town hunting clubs own a walk-in freezer for their members.
 
Just buy the shell off FB. You may be able to find a complete unit, or go with the A/C and coolbot.
 
cool-bot seems to work well
 
Our hunting club has one. Make sure you can control the humidity. Too humid, and things mold. Too dry, and the outer layers get dessicated.

I think you'll love it once you get it working properly. It will open up a whole world of possibilities making your own charcuterie.
 
Interesting post. I sold frank the tank, the 20" 13hp rototiller. Was kicking my butt too much. Guy who bought it had 3 walk in coolers for sale.
