Couldn't a TEC controller just be made with a t-balancer driving a relay or a power resistor?
Or just a simple curcuit with a thermistor and a variable resistor switching the TEC on above a certain temp. Ofcourse precision might be a bit off, a digital thermometer and a PIC controller could make it much more accurate (as accurate as the digital thermometer) and easier to vary between different temperatures. No complex circuit would be needed for that, just a bit of knowledge with programming PICs. Add a 16x1 lcd display and there might just be a small market. |

@Nugit and moonlightcheese
yes, but you'd get something like these: http://www.omega.com/ppt/pptsc.asp?ref=CN132 http://www.ttiglobal.com/Product.aspx?ProductID=3411 examples. which there is a vast product range, and prices. but, again, expensive for the private buyer.

That only cools 150w though, a dual 320 watt setup would have considerably better performance (if constructed correctly).

I will need at least 300watts to keep things were I want them. Thats why I figured 2 tecs over 300watts and then half the power to each of them. Should work out. I plan on making my heat die variable from 50watts to 150watts. And then the pump it self is like 55watts. I figure 300watts should be enough to drop the temps below room temp if room temp goes above 25C. |

I think that will work.
I assume you are going to insulate the system, this should improove efficency by allot if you do a good job ![]() Edit - there is a thread on the PSU / controll system here - http://forums.procooling.com/vbb/showthread.php?t=12147 Last edited by Holst; 08-31-2005 at 10:22 AM. |

I was able to start moving into my new place and I think I might not have to worry about chilling the water. THe new place not only has an A/C already in the room but the whole place is cool all day long as it is shaded.
![]() I am still going to build this chiller though. Just might not do it as soon as I was planning. |
