Hello, I have been interested in using thermoelectric coolers, (Peltiers) for many applications. But, I don't know how to control them. I hear that simple on and off switching can be damaging to the module. But how else can I control it? If I use any kind of thermostat, I can't have it be anything too complex.
The application that I want to use one for now, is water cooling. I will be cooling about a 1/2 gallon of water with a 70 Watt module. Well, I'm gonna try at least... but I don't know if it will cool it enough, too much, or waste too much power. This is going to be drinking water, so the temerature needs to be from about 50-60 degrees Fahrenheit... or so. (Or 10-15 degrees Celsius). The water will be in a metal dish and I want to mount the module on the bottom of it. So, really I'm asking for the answers to the following questions:
1. How can I control it to keep the water temperature around 50-60 degrees Fahrenheit?
2. Will a 70 watt module be cold and powerful enough to cool a 1/2 gallon of water?
3. Will the module be overworking itself and killing my electric bill trying to keep the water cool?
4. Generally, how cold are these coolers? Can I even use them for applications like these or are they more for cooling electronic parts and stuff like that? If so, then what should I use to cool this water? I don't want to mess around with chemicals like freon, that's why I was so happy when I found these modules.
Can anyone please help me? :? Thanks.
