Peltier Water Cooler Machine / Thermoelectric Cooler / Water Chiller / Cooling Device
This video shows peltier experiments where I explore using water or liquids as the cooling/heating medium instead of air. I am on a quest to find out what works best and most efficient so that I can use that knowledge to build devices in the future such as cooling device for CO2 laser, cooling small rooms, air cooling ,DIY small fridge or mini air conditioner and maybe even an ice maker.

By using powerful 100W peltier (thermoelectric cooler) modules, with giant heat sinks and water blocks, I was able to chill a 1L glass of water from 26,3 °C down to 13,3°C in matter of 15 min.
outdoors sunny weather: ambient temperature 35 ° C
