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 =) Digital Thermostat Temperature Controller Red And Blue Display DC 12V 20A W3230 720643648147 | eBay Peltier Thermoelectric Module Peltierelement 12V TEC1-12706 12708 12710 12712 | eBay 40x40mm Primary Aluminium Water Cooling Block For Liquid Water Cooler For PC CPU | eBay 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. 2Pc 1m x 1.8m Self Adhesive 6mm Double Bubble Foil Thermal Insulation Camper Van 783101476140 | eBay 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 =)
Started a bit of work on the electrical part of the project today. Also cut a hole in the lid for the digital thermostat.
What amount of water flow are you expecting to see, c0rn? I mean, as far as a flow rating, how much water can it cool and how long will it take to cool that much when you're done?
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
