Fantastic!! I’ve recently did similar using an old dehumidifier (even more efficient). You can add cheap 0degC Temp switches on the evaporator line to automatically shut down to thaw… I bought two cheap digital temperature controllers from Amazon and plugged them in series. One stops the unit when water temp is reached and other detects frost on the line to shut and thaw. I pump the water (USE DEMINERALIZED WATER / RAINWATER!) through a couple of old quad / atv radiators (which have steel fins instead of fragile aluminum) in two rooms, with large computer fans pulling the air through… I use the same piping radiators with coils around woodstove for heating in winter!

Very Kool! Thanks!

Thanks dude this helps out a lot

I'd add a small water proof box to the top of the AC unit for holding the 2 outlets. Then I'd add 2 switched outlets inside and make sure that this all plugs into a GFCI outlet or breaker. Try an keep the power away from the water as much as you can.

Trying to do this for my hydroponic setup - might just get a used unit off craigslist to try

what are u using the chilled water for? just curious?

I’m in the process of making a chiller, following your recommendations.

Can I use the same method for salt water tank

nice....you think sealing the coil to the sides of the cooler would force the water thru the coil and not around it...that may cause your freezing....

Do you think this could work with a 200 liter reflux still? I heat the boiler with propane (24kcal).

Nice job

What about the exhaust? I love this idea but concerned about heating the room with the exhaust

I was looking for a way to cool my koi pond water. I already have the water being pumped through a skimmer into a large plastic garbage can which provides filtration. I was thinking I could place a cheap air conditioner on top and removing the coil and placing it into the filter so the water returns to the pond colder. What do you think?

Nice set up ! I’m in the middle of making one . Any suggestions on how not to link the tubing, Possibly using some heat ? I’d appreciate any advice as that’s the stage i’m at .

Brilliant Mate, I may need to give that a crack.

Does the cooler need to be so big ( will need more time to cool the water ) i will be using it for a 6 gallon beer

what about corrosion of the evaporator? I made something like it for heating water and worrying about corrosion..

Sir, How much time it takes room temperature water to reach 40 deg f?

I wonder what your rear fan diameter is. I like this setup but was thinking about a fixed mount on a counter and ducting the high side outside through the wall. I was even considering a possible option of replacing or just supplementing the rear fan with about a 400 CFM inline exhaust fan pulling through the high side coils because I'd have to reduce that diameter. My problem is being in a room inside a house where putting everything on wheels is not practical and I want to be able to pull the heat outside. I've got the sheet metal and some ducting already just sitting around. Anybody tried anything like this yet?

How’s this design holding up? Thinking about making one as well but wanted to see what the longevity is thnx
