Make AC for fishes! DIY Aquarium Water Chiller - Ep 2: Wiring and Testing

[@LawAbidingCitizen117]

You need to use the most efficient peltier module, TEC1-12708. Assemble at least 4 of them in parallel and feed only 6 amps for each. In total you would need to feed 6x4 = 24amps at 12V. Don't use those heatsinks, they aren't enough to pump out the heat from the hot side. Use water cooling, aluminium cooling blocks and radiator setup.

Hi i wonder if you can help me with my water chiller i believe it does have the same hardware, but my fan iant working and it is not getting cold or warm it, the set button is not working too, its not a diy, its from china that i ordered online and it work on first try but when i connected to my aquarium, it became defective the fan is not running. maybe you can help me?

[@byc0705]

I would google the model number and see if someone had the same issue or there’s a manual to follow. After trying that if it’s still not working I would need to test with a multimeter to check if there’s current running through the device because based on the description there’s none. Sorry that I can’t be more helpful and hope you get it fixed soon.

[@jecayoyao2638]

Yes I followed your instructions and it worked, after some videos even if it doesnt have the same model. Your video is helpful! I worked on the time delays so it is not defective! 😅 thanks to you!

Hi , i tried to copy but the pump wont suck the water , any tips?

[@byc0705]

I guess it’s air lock. You may try filling the pump and tube with water. Leave as less air as possible in the system then start pumping. Hope this will solve the problem. Thanks.

what power adapter do you use?

[@byc0705]

12V 10A AC to DC Adapter with Car Cigarette Lighter Socket

[@ujang3288]

Did you use peltier for the cooling?

[@byc0705]

Yes. By the way, the device can easily transform to a heater by giving the Peltier inverted current, so it can be used in winters.

[@jennisonr]

i tried this, but i find the change in water temperature to be marginal, what may have gone wrong?

[@byc0705]

The temperature change range heavily depends on the tank size, i.e. the water volume being cooled down. Room temperature also affects the performance.

Hi Brad, I dont know why but I did everything as per the setup but still even one jug of water is not cooled :(, would you like to get in touch over an email/watsapp to identify the root cause ?? Awaiting positive response. Thanks for your help.

[@byc0705]

I would bypass the control module for now. Connect the Peltier directly to the 12V power supply for 3 seconds. If you can feel the coldness, and the heat on the other side, you know the Peltier is fine(do the same to the pump and fan to test them) and the issue is likely with the control module. May be the wiring or setting.

How much to ship? haha. I would totally buy one of these if you'd be willing to make one up and give me a quote haha

[@byc0705]

Thank you for being interested in my work. It’s truly an encouragement for me because I’ve never imagined someone would be willing to buy my product. However, my device has not been through rigorous tests under extreme conditions, and therefore may not work in all environments. I would recommend commercial water chiller on the market. Thanks again!

@@byc0705 keep up the good work man.. i enjoy watching the builds!

Giusto un bicchiere di acqua raffreddi, niente di piu'.

Waste of time. Buy a chiller and save your time.
