Cooling down temps in my DIY Aeroponics unit with 100w peltier

Hi all!

I started a thread a while ago regarding my DIY Aeroponics/DWC build that can be found on the below link.
Homemade low pressure Aeroponics/DWC hybrid

The DIY box is working great except for the water temps. So the next part of the project is to cool down the water.

I never have over 4 US Gallons (15 liters) in my res so I do not need a large cooler. So I am planing on building a Peltier 100w cooler. I know they are not the most efficient but for a small res they should be fine I hope and I only need to cool between 4-5C.

I have ordered some parts of eBay and now I am waiting on the parts to arrive. I will be sharing my findings in case it works good and anybody wants to build the same =)

2Pc 1m x 1.8m Self Adhesive 6mm Double Bubble Foil Thermal Insulation Camper Van, I will insolate the box and lid with this stuff and I am hoping this will help a little bit extra so I do not have to run the Peltier cooler all the time.

I already have a spare PC cooler that is rated for 150w cooling.


I also have a bunch of 12v 10-20a 120-240w power supplies at home.

This should be fun =)

 

So I started building the "plate" that everything will be attached to today.

 

Once all the cables are in place it will not look nice anymore hehe

 

@StickyBudHound, here you go man =)

 

Preach it brother =)

 

Started a bit of work on the electrical part of the project today.





Also cut a hole in the lid for the digital thermostat.

 

To be honest I am not sure, it's hard to find any numbers and actual proper testing from any other projects.

So I will have to just test and document in hopes that it will help other people. I am not even sure this will work good at all. Keep finding loads of projects but no real numbers.

Flow rates will be hard to know until I test the water block, I have done loads of custom built water cooling on PCs and flow rates can change loads depending on the water block.

 

I changed my mind a bit regarding this chiller. I ordered a Hailea HC100a that I will be using with my grow box for my girls.

I will instead use this chiller with a future chili grow.

Honestly I want to use something I built myself but I also want to make sure that I thoroughly test it first, once I have tested it and I am happy with the results I will use it in my tent. Currently I really need something that really works in my grow space

 

Small updates, waiting on some tubing that will fit on the water block. Still a bit of wiring to do. But getting there slowly
